Abstract

The method involves using a melting device (7,8) which produces a hot melt adhesive and is carried along with the foil roller (5) during a displacing movement. The melting device is located on a work platform (10) which remains horizontal during the displacing movement. The displacing movement occurs by means of a movement mechanism (4) which has a telescopic arm (12). The swivel axis (11) of the arm is moveably arranged on the support structure. Independent claims are included for: (1) a device to attach sheetings to the tunnel wall, and (2) the use of foamed hot melt adhesive for fixing sheetings to tunnel arches, especially for fixing the sheetings to spray concrete arches.

Description

Die Erfindung betrifft ein Verfahren zum Befestigen von Folienbahnen an Bauwerksflächen, insbesondere an Tunnelwänden, bei welchem mindestens eine Folienrolle durch eine Verlegebewegung entlang der zu bedeckenden Fläche bewegt und dabei die Folienbahn von der Rolle abgezogen und an die Fläche angelegt wird, wobei die Folienbahn durch von einer Schmelzeinrichtung erzeugten Schmelzklebstoff an der Fläche befestigt wird. Weiter betrifft die Erfindung eine entsprechende Vorrichtung zum Befestigen von Folienbahnen an Bauwerksflächen, insbesondere an Tunnelwänden, gemäss Oberbegriff des Anspruches 15.The invention relates to a method for attaching film webs to building surfaces, in particular tunnel walls, wherein at least one film roll moves by an installation movement along the surface to be covered, while the film web is removed from the roll and applied to the surface, wherein the film web by A melt adhesive produced hot melt adhesive is attached to the surface.

Ein Verfahren bzw. eine Vorrichtung zur Verlegung von Folienbahnen ist aus WO 01/02700 bekannt. Dieses Dokument zeigt die Verlegung von Dichtungsfolien mittels eines Verlegewagens, der entlang einer der Bauwerksfläche angepassten Führungsbahn fährt. Die von einer Rolle abgezogene Dichtungsfolienbahn wird mittels Hotmelt-Klebstoff befestigt. Die Schmelzeinrichtung für den Klebstoff ist stationär an einem Portalwagen angeordnet, der die Führungsbahn trägt. An dem Verlegewagen ist ein beheizbarer Arbeitsspeicher für den Klebstoff vorgesehen, der in einer Endstellung des Verlegewagens mit geschmolzenem Klebstoff aus der stationären Schmelzeinrichtung befüllbar ist. Diese bekannte Anordnung ist eine Weiterentwicklung der aus CH-A-652 448 bekannten Anordnung, bei welcher die Verlegeeinrichtung über einen flexiblen Schlauch mit der stationären Schmelzeinrichtung verbunden ist.A method and a device for laying film webs is known from WO 01/02700. This document shows the laying of sealing foils by means of a laying carriage which travels along a guideway adapted to the surface of the building. The sealing film web removed from a roll is fastened by means of hot melt adhesive. The melting device for the adhesive is stationarily arranged on a portal trolley, which carries the guideway. On the laying carriage, a heatable working memory for the adhesive is provided, which can be filled in an end position of the laying carriage with molten adhesive from the stationary melting device. This known arrangement is a further development of the known from CH-A-652 448 arrangement in which the laying device via a flexible Hose is connected to the stationary melting device.

Der Erfindung liegt die Aufgabe zugrunde ein verbessertes Verlegeverfahren zu schaffen.The invention has for its object to provide an improved installation method.

Dies wird bei dem Verlegeverfahren der eingangs genannten Art dadurch erreicht, dass die Schmelzeinrichtung bei der Verlegebewegung mit der Folienrolle mitgeführt wird.This is achieved in the laying method of the type mentioned in that the melting device is entrained in the laying movement with the film roll.

Im Unterschied zum Stand der Technik wird also die gesamte Schmelzeinrichtung mit der Folienrolle entlang der Bauwerksfläche verfahren und ist bei der Verlegung einer Folienbahn nicht stationär. Dadurch sind sehr kurze Verbindungsleitungen von der Schmelzeinrichtung bis zur Auftragsstelle für den Schmelzklebstoff auf die Folienbahn möglich. Es entfallen somit störungsanfällige, lange Leitungen mit heissem Schmelzklebstoff und es entfallen auch spezielle Zapfventile. Der Schmelzklebstoff wird direkt beim Verlegen der Folienbahn von der mitbewegten Schmelzeinrichtung erzeugt.In contrast to the prior art, therefore, the entire melting device is moved with the film roll along the building surface and is not stationary when laying a film web. As a result, very short connecting lines from the melting device to the application point for the hot melt adhesive to the film web are possible. It thus accounts for fault-prone, long lines with hot melt adhesive and it eliminates special nozzles. The hotmelt adhesive is produced directly during the laying of the film web by the co-moving melting device.

Bevorzugterweise wird eine Schmelzeinrichtung eingesetzt, die unter Gaszufuhr einen geschäumten Schmelzklebstoff erzeugt. Dabei wird bevorzugterweise auch der dazu benötigte Gasvorrat zusammen mit der Schmelzeinrichtung bei der Verlegebewegung mitgeführt. Der geschäumte Schmelzklebstoff zeigt als Vorteile gegenüber dem bisher verwendeten ungeschäumten Schmelzklebstoff einen geringeren Klebstoffverbrauch pro Quadratmeter Folie, ein nur geringes oder gar völlig fehlendes Abtropfen von geschmolzenem Klebstoff beim Auftrag "über Kopf" sowie eine erhöhte Klebkraft. Es hat sich gezeigt, dass geschäumter Schmelzklebstoff das direkte Verkleben von Folienbahnen auf Spritzbeton ermöglicht.Preferably, a melting device is used which generates a foamed hot melt adhesive while supplying gas. In this case, preferably also the gas supply required for this purpose is carried along with the melting device during the laying movement. The foamed hot melt adhesive shows as advantages over the previously used unfoamed hot melt adhesive lower adhesive consumption per square meter of film, a little or even complete dripping of molten adhesive when applied "overhead" and increased adhesion. It has been shown that foamed hot melt adhesive allows the direct bonding of film webs on shotcrete.

Bevorzugt ist es, wenn die Schmelzeinrichtung auf einer bei der Verlegebewegung im wesentlichen horizontal bleibenden Plattform mitgeführt wird. Dies erlaubt es, eine für den stationären Betrieb ausgestaltete, handelsübliche Schmelzeinrichtung bei der Verlegebewegung einzusetzen. Vorzugsweise ist ferner die Plattform auch als Arbeitsbühne ausgestaltet, was das Mitführen einer Bedienungs- bzw. Kontrollperson bei der Verlegung bzw. dem Schmelzklebstoffauftrag ermöglicht.It is preferred if the melting device is carried along on a platform that remains essentially horizontal during the laying movement. This makes it possible to design a commercially available melting device designed for stationary operation during the laying movement use. Preferably, the platform is also designed as a working platform, which allows the entrainment of an operator or control person during installation or hot melt adhesive application.

Das erfindungsgemässe Vorgehen kann bei einer beliebigen Verlegevorrichtung verwendet werden. So könnte z.B. ein Verlegewagen gemäss der WO 01/02700 verwendet werden, der dann aber gemäss der Erfindung die Schmelzeinrichtung mitführt. Bevorzugt wird indes eine schwenkbare, längeneinstellbare Bewegungseinrichtung zur Ausführung der verlegebewegung, insbesondere ein schwenkbarer längeneinstellbarer Arm, insbesondere ein Teleskoparm, anstelle eines auf einer vorgegebenen Führungsbahn fahrenden Wagens. Die bevorzugte Ausführungsform erlaubt eine einfache Anpassung an verschiedenste Bauwerksflächen, insbesondere verschiedene Tunnelprofildurchmesser.The inventive method can be used in any installation device. So could e.g. a laying carriage according to WO 01/02700 are used, but then carries the melting device according to the invention. However, preference is given to a pivotable, length-adjustable movement device for carrying out the laying movement, in particular a pivotable, length-adjustable arm, in particular a telescopic arm, instead of a carriage traveling on a predetermined guideway. The preferred embodiment allows a simple adaptation to a variety of building surfaces, in particular different tunnel profile diameter.

Der Erfindung liegt ferner die Aufgabe zugrunde eine verbesserte Vorrichtung zur Befestigung von Folienbahnen zu schaffen.The invention is also based on the object to provide an improved device for fastening film webs.

Dies wird bei der eingangs genannten Vorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 15 erreicht. Dadurch, dass die Schmelzeinrichtung mit der Folienrollenaufnahme bei der Verlegebewegung mitgeführt wird, ergeben sich die vorstehend anhand des Verfahrens erläuterten Vorteile.This is achieved in the aforementioned device with the characterizing features of claim 15. The fact that the melting device is carried along with the film roll receptacle during the laying movement results in the advantages explained above with reference to the method.

Dadurch, dass die Folienrollenaufnahme bevorzugterweise an einer horizontal verstellbaren und schwenkbaren Bewegungseinrichtung für die Ausführung der Verlegebewegung angeordnet ist, ergibt sich eine einfach an verschieden verlaufende Bauwerksflächen, insbesondere verschiedene Tunnelprofile, anpassbare Vorrichtung.Because the film roll receptacle is preferably arranged on a horizontally adjustable and pivotable movement device for carrying out the laying movement, the result is an easily adaptable building surface, in particular different tunnel profiles, adaptable device.

Vorzugsweise ist eine Längeneinstellung, insbesondere ein längeneinstellbarer Arm, insbesondere ein Teleskoparm vorgesehen. Weiter ist es bevorzugt, wenn die Längsachse der Folienrollenaufnahme jeweils in der durch sie verlaufenden Horizontalebene schwenkbar ist. Ferner ist es bevorzugt, wenn die Längsachse der Folienaufnahme aus der Horizontalebene heraus neigbar ist. Bevorzugterweise wird die eine oder die andere oder werden beide der genannten Bewegungen der Längsachse der Folienrollenaufnahme am der Folienrollenaufnahme entgegengesetzen Ende der Bewegungseinrichtung, insbesondere des Teleskoparmes bewirkt. Insbesondere werden sie bewirkt, indem die Bewegungseinrichtung, insbesondere der Arm bzw. Teleskoparm entsprechend an der Tragstruktur gelagert ist, so dass die genannten Bewegungen unabhängig voneinander und unabhängig von der Verlegebewegung ausführbar sind. Vorzugsweise ist eine zweite Bewegungseinrichtung, insbesondere ein weiterer Teleskoparm, vorgesehen, welche Bewegungseinrichtung unabhängig von der ersten Bewegungseinrichtung bewegbar ist. Die zweite Bewegungseinrichtung ist z.B. ebenfalls linear verschieblich und schwenkbar. Sie trägt vorzugsweise die Schweisseinrichtung für die Folien.Preferably, a length adjustment, in particular a length-adjustable arm, in particular a telescopic arm is provided. Further, it is preferred if the longitudinal axis of the film roll receptacle is in each case pivotable in the horizontal plane extending through it. Furthermore, it is preferred if the longitudinal axis of the film receptacle can be tilted out of the horizontal plane. Preferably, one or the other or both of said movements of the longitudinal axis of the film roll receptacle on the film roll receiving opposite end of the movement means, in particular of the telescopic arm causes. In particular, they are effected by the movement device, in particular the arm or telescopic arm is mounted accordingly on the support structure, so that said movements are independent of each other and independently of the laying movement executable. Preferably, a second movement device, in particular a further telescopic arm, is provided, which movement device is movable independently of the first movement device. The second moving means is e.g. also linearly displaceable and pivotable. It preferably carries the welding device for the films.

Vorzugsweise ist die Tragstruktur für die Bewegungseinrichtung ein Portalwagen, der entlang dem Bauwerk verfahrbar ist, insbesondere innerhalb eines Tunnels auf Schienen verfahrbar ist. Vorzugsweise ist die Bewegungseinrichtung am Portalwagen und ist der Portalwagen selber in eine Transportstellung bringbar.Preferably, the support structure for the movement device is a portal trolley, which can be moved along the structure, in particular can be moved on rails within a tunnel. Preferably, the movement device on the portal carriage and the portal carriage itself can be brought into a transport position.

Figur 1 zeigt schematisch eine in einem Tunnelgewölbe 2 angeordnete Verlegevorrichtung 1. Das Tunnelgewölbe 2 steht dafür als Beispiel für beliebige Bauwerksflächen. An der Innenseite 3 des Gewölbes soll eine Abdichtung in Form von Folienbahnen verlegt werden, welche auf bekannte Weise sich überlappend bahnweise nacheinander entlang der Tunnellängserstreckung auf die Tunnelinnenwandung aufgebracht werden, indem Folienbahn für Folienbahn nacheinander von der einen Schnittstelle der Wandung 3 mit der Tunnelsohle 16 zur anderen Schnittstelle der Wandung 3 mit der Sohle 16 auf die Wandung aufgeklebt wird. Mit Folie ist hier jede beliebige Art von folienartigem Dichtungsmaterial, z.B. eine Kunststoffdichtungsbahn, KDB, oder anderem folienartigen Material gemeint, welches beim Tunnelbau oder bei anderen Bauwerksflächen bahnweise Verwendung findet. Es kann sich um einschichtige oder mehrschichtige Folien handeln oder auch um Gewebebahnen oder Vliesbahnen, die hier auch vom Begriff Folie mitumfasst sein sollen, oder um solche Bahnen in Kombination mit Kunststofffolien. Die Bahnen werden im Tunnelbau in der Regel sich mit ihren Randbereichen überlappend verlegt und im Überlappungsbereich verschweisst. Die Folien werden als Rollenmaterial konfektioniert, wobei eine Rolle z.B. ein Gewicht von 150-200 kg haben kann. Die Folien könnten aber auch gefaltet als Pakete vorliegen, was indes für die vorliegende Erfindung keinen Unterschied macht; es sollen hier beide Arten der Folienkonfektionierung bzw. des Folienvorrates als umfasst gelten. Die Befestigung der Folie an der Tunnelinnenwandung 3 erfolgt bei dem ersten Aspekt der vorliegenden Erfindung mittels eines Schmelzklebstoffes. Damit sind alle Arten von Klebstoffen gemeint, welche durch Erhitzen flüssig und verarbeitungsfähig werden und sich beim Erkalten verfestigen und die zu verklebenden Teile auf diese Weise verbinden. Andere Bezeichnungen für solche Klebstoffe sind z.B. Heissleim oder Hotmelt.FIG. 1 schematically shows a laying device 1 arranged in a tunnel arch 2. The tunnel arch 2 stands for this as an example of any building surfaces. On the inside 3 of the vault a seal in the form of film webs to be laid, which are applied in a known manner overlapping web by line along the tunnel longitudinal extension of the tunnel inner wall by film web for film web successively from the one interface Wall 3 is glued to the tunnel sole 16 to the other interface of the wall 3 with the sole 16 on the wall. With foil here is meant any type of foil-like sealing material, for example a plastic sealing strip, KDB, or other film-like material, which is used in web-like manner during tunneling or other building surfaces. They may be single-layered or multi-layered films or may also be fabric webs or nonwoven webs, which should also be included here by the term film, or such webs in combination with plastic films. As a rule, the runways are laid overlapping with their edge areas in tunneling and welded in the overlapping area. The films are made up as roll material, with a roll, for example, may have a weight of 150-200 kg. The films could also be folded as packages, which, however, makes no difference to the present invention; Both types of film preparation or of the film stock should be considered to be included here. The attachment of the film to the tunnel inner wall 3 takes place in the first aspect of the present invention by means of a hotmelt adhesive. By this is meant all types of adhesives which become liquid and workable by heating and solidify on cooling and join the parts to be bonded in this way. Other names for such adhesives include hot glue or hotmelt.

Figur 1 zeigt nun schematisch eine Vorrichtung 1 gemäss dem ersten und dem zweiten Aspekt der Erfindung mit einer Bewegungseinrichtung 4, welche um eine Achse 11 schwenkbar an einer Tragstruktur 6 der Vorrichtung angeordnet ist. An ihrem freien Ende trägt die Bewegungseinrichtung 4 unter anderem eine Folienrolle 5. Diese Rolle 5 wird durch die Bewegungseinrichtung entlang der Bauwerkswandung bzw. der Tunnelwandung in einer kontinuierlichen Verlegebewegung bewegt, so dass die von der Rolle abgerollte Folienbahn die Wandung bedeckt. Dies ist in Figur 1 durch verschiedene Stellungen der Folienrolle 5 entlang der Tunnelwandung dargestellt. Die Klebeverbindung der Folienbahn mit der Wandung 3 erfolgt dadurch, dass auf die Folienbahn mehrere sich kontinuierlich oder mit Unterbrechungen entlang ihrer Länge erstreckende, voneinander beabstandete Klebstoffraupen kurz vor dem Andrücken der Folienbahn an der Wandung auf die Folienbahn aufgebracht werden. Diese Raupen aus erhitztem, flüssigem Schmelzklebstoff erkalten beim und nach dem Anpressen der Folie an der Wandung und schaffen die Klebverbindung zwischen Wandung 3 und der Folie.Figure 1 shows schematically a device 1 according to the first and the second aspect of the invention with a movement device 4, which is arranged about an axis 11 pivotally mounted on a support structure 6 of the device. Among other things, the movement device 4 carries a film roll 5 at its free end. This roll 5 is moved by the movement device along the building wall or the tunnel wall in a continuous laying movement, so that the film web unwound from the roll covers the wall. This is represented in Figure 1 by different positions of the film roll 5 along the tunnel wall. The adhesive bond of the film web to the wall 3 takes place in that a plurality of adhesive beads extending continuously or intermittently along their length are applied to the film web shortly before the film web is pressed against the wall on the film web. These beads of heated, liquid hot melt adhesive cool during and after the pressing of the film on the wall and create the adhesive bond between the wall 3 and the film.

Gemäss einem ersten Aspekt der Erfindung wird nun die Schmelzeinrichtung, welche den flüssigen Schmelzklebstoff erzeugt, bei der Verlegebewegung mit der Folienrolle oder dem Folienpaket bzw. dem Folienvorrat mitgeführt. Figur 1 und Figur 2 zeigen dazu, dass die Schmelzeinrichtung 7, welche eine bekannte handelsübliche Schmelzeinrichtung für Schmelzklebstoffe ist, an der Bewegungseinrichtung 4 angeordnet ist, die auch die Folienrolle 5 trägt, von der die Folie 15 abgezogen wird. Die Schmelzeinrichtung kann dabei auf beliebige Art und Weise an der Bewegungseinrichtung angeordnet sein, so dass sie deren Bewegung zusammen mit dem Folienvorrat (Folienrolle oder Folienpaket) mitmacht. Bei dem in Figur 1 und Figur 2 dargestellten Beispiel ist die Schmelzeinrichtung 7 auf einer Plattform 10 angeordnet, welche an der Bewegungseinrichtung so aufgehängt ist, dass die Plattform bei der Bewegung entlang der zu bedeckenden Bauwerksfläche 3 bzw. Tunnelwandung 3 im wesentlichen horizontal bleibt. Dies ist aus den verschiedenen Stellungen der Plattform 10 in Figur 1 ersichtlich. Von der Schmelzeinrichtung 7 führt mindestens eine Leitung 9 zu den Auftragsköpfen 17, welche auf der von der Rolle 5 abgerollten Folie 15 die Klebstoffraupen ablegen. Es kann dabei eine Leitung 9 vorgesehen sein, welche zu einem Leimbalken führt, der mehrere beabstandete Austrittsöffnungen aufweist. Bevorzugt ist es allerdings, wenn mehrere separate Auftragsköpfe 17 vorgesehen sind, zu denen jeweils eine separate Leitung 9 aus der Schmelzeinrichtung 7 führt. Die Förderung in den Leitungen 9 zu den Auftragsköpfen wird in der Regel durch eine in der Schmelzeinrichtung vorgesehene Pumpe durchgeführt. Falls die Schmelzeinrichtung selber keine Pumpe enthält, so ist eine separate Pumpenanordnung dafür vorzusehen. Die Schmelzeinrichtung 7, die mit der Bewegungseinrichtung mitgeführt wird, ist vorzugsweise eine Schmelzeinrichtung zur Herstellung von geschäumtem Schmelzklebstoff. Eine solche bevorzugt verwendete Schmelzeinrichtung ist z.B. der Typ "Foam-Melt® 200", der z.B. von der Firma Nordson Deutschland GmbH, Erkrath, Deutschland vertrieben wird oder durch weitere Niederlassungen der Firma Nordson. Diese Schmelzeinrichtung erzeugt aus bekanntem festem Schmelzklebstoff unter Zufuhr eines Gases, z.B. industriellem Kohlendioxid oder Stickstoff, einen schaumförmigen Schmelzklebstoff. Dieser kann auf die genannte Weise über die Leitungen 9 und die Austragsköpfe 17 auf die Folie abgegeben werden. Bevorzugterweise wird dazu auch der Gasvorrat von der Bewegungseinrichtung mitgeführt, was in Figur 1 und 2 durch einen Gastank 8 dargestellt sein soll. Durch die Mitführung einer Schmelzeinrichtung zusammen mit dem Folienvorrat bei der Verlegebewegung ergibt sich, wie in den Figuren ersichtlich, eine besonders einfache Konstruktion und eine kurze Leitungsführung für den heissen Schmelzklebstoff. Zum Betrieb der Schmelzeinrichtung bei deren Mitführung mit der Bewegungseinrichtung wird lediglich die Zufuhr von elektrischer Energie für die Schmelzeinrichtung benötigt. Die benötigte Menge von festem Schmelzklebstoff, der in der Schmelzeinrichtung aufgeschmolzen wird, kann in dieser mitgeführt werden. Beim Vorsehen einer Plattform kann auf dieser auch ein Vorrat von festem Schmelzklebstoff mitgeführt werden, welcher für mehrere vollständige Verlegebewegungen ausreicht. Jedenfalls sollte die Schmelzeinrichtung so bemessen sein, dass sie mindestens Schmelzklebstoff für eine vollständige Verlegebewegung wie in Figur 1 gezeigt enthalten kann. Bei der bevorzugten Verwendung von geschäumtem Schmelzklebstoff erfolgt die Verlegung wie bereits für normalen Schmelzklebstoff geschildert. Es hat sich gezeigt, dass der geschäumte Schmelzklebstoff bei der vorliegenden Anwendung mehrere Vorteile aufweist. So erfolgt z.B. praktisch kein Tropfen von Schmelzklebstoff wenn über Kopf gearbeitet wird, wie dies ersichtlicherweise bei der Verlegebewegung an einer Tunnelwandung vorkommt. Ferner wird durch die Aufschäumung weniger Schmelzklebstoffmaterial benötigt und es ergibt sich eine erhöhte Klebkraft. Die Verwendung geschäumten Schmelzklebstoffes ermöglicht es sogar Folienbahnen direkt auf Tunnelwandungen 3 aus Spritzbeton zu kleben. Dies war bis anhin mit herkömmlichen, nicht geschäumten Schmelzklebstoffen nicht immer mit Sicherheit durchführbar. Als bevorzugter Schmelzklebstoff für die Anwendung auf Spritzbeton im Tunnelbau kommt z.B. der Typ Ecomelt A3 EX159 der Firma Collano AG, Schweiz zur Anwendung. Der geschilderte Aspekt der Erfindung, wonach die Schmelzeinrichtung bei der Verlegebewegung mitgeführt wird, kann grundsätzlich bei beliebiger Ausführung der Verlegebewegung verwendet werden. So ist es durchaus möglich bei einem Verlegewagen, welcher entlang einer Führungsbahn gefahren wird, ebenfalls die Schmelzeinrichtung mitzuführen.According to a first aspect of the invention, the melting device which produces the liquid hotmelt adhesive is now carried along with the film roll or the film package or the film supply during the laying movement. Figure 1 and Figure 2 show that the melting device 7, which is a known commercially available melting device for hot melt adhesives, is arranged on the movement device 4, which also carries the film roll 5, from which the film 15 is pulled off. The melting device can be arranged on the movement device in any desired manner, so that it participates in its movement together with the film supply (film roll or film package). In the example shown in FIG. 1 and FIG. 2, the melting device 7 is arranged on a platform 10, which is suspended on the moving device in such a way that the platform remains essentially horizontal during the movement along the building surface 3 or tunnel wall 3 to be covered. This can be seen from the various positions of the platform 10 in FIG. At least one line 9 leads from the melting device 7 to the application heads 17, which deposit the adhesive beads on the film 15 which has been unrolled from the roll 5. It can be provided a line 9, which leads to a glue bar having a plurality of spaced outlet openings. It is preferred, however, if several separate guns 17 are provided, to each of which a separate line 9 leads from the melting device 7. The delivery in the lines 9 to the guns is usually carried out by a pump provided in the melting device. If the melting device itself does not contain a pump, it is necessary to provide a separate pump arrangement for this purpose. The melting device 7, which is carried along with the movement device, is preferably a melting device for producing foamed hot melt adhesive. Such a preferably used melting device is, for example, the type "Foam-Melt ® 200", which is sold for example by the company Nordson Germany GmbH, Erkrath, Germany or by other branches of Nordson. This melting device produced from known solid hot melt adhesive with the supply of a gas, such as industrial carbon dioxide or nitrogen, a foam-like hot melt adhesive. This can be discharged in the said manner via the lines 9 and the discharge heads 17 on the film. Preferably, the gas supply is also carried along by the movement device, which should be represented by a gas tank 8 in FIGS. 1 and 2. The entrainment of a melting device together with the film supply in the laying movement results, as can be seen in the figures, a particularly simple construction and a short cable routing for the hot melt adhesive. For the operation of the melting device in their entrainment with the moving means only the supply of electrical energy for the melting device is required. The required amount of solid hot melt adhesive, which is melted in the melting device, can be carried in this. When providing a platform can also be carried on this a supply of solid hot melt adhesive, which is sufficient for several complete installation movements. In any case, the fuser should be sized to contain at least hot melt adhesive for a complete installation movement as shown in FIG. In the preferred use of foamed hot melt adhesive laying is as already described for normal hot melt adhesive. It has been found that the foamed hot melt adhesive has several advantages in the present application. Thus, for example, there is practically no drop of hot melt adhesive when working overhead, as evidently occurs during the laying movement on a tunnel wall. Furthermore, less foaming adhesive material is needed by the foaming and there is an increased bond strength. The use of foamed hot melt adhesive even makes it possible to glue foil webs directly to tunnel walls 3 made of shotcrete. Until now, this was not always feasible with conventional, non-foamed hot melt adhesives. As a preferred hot melt adhesive for use on shotcrete in tunneling, for example, the type Ecomelt A3 EX159 from Collano AG, Switzerland is used. The described aspect of the invention, according to which the melting device is carried along during the laying movement, can in principle be used in any embodiment of the laying movement. So it is quite possible in a laying carriage, which is driven along a guideway, also carry the melting device.

Nach einem weiteren Aspekt der Erfindung wird die Bewegungseinrichtung 4, welche die Verlegebewegung bewirkt so ausgeführt, dass diese ein schwenkbares Element umfasst, welches insbesondere ein schwenkbarer Arm 12 und insbesondere ein schwenkbarer teleskopischer Arm 12 ist, der zur Durchführung der Verlegebewegung um eine Achse 11 an der Tragstruktur 6 schwenkbar ist. Wie aus Figur 1 ersichtlich, ist die Achse 11 von der einen Seite der Tragstruktur zur anderen Seite der Tragstruktur parallel verschieblich (entlang der Linie A), so dass sich ein erweiterter Bereich für die Verlegebewegung ergibt. In dem Beispiel erfolgt die Verschiebung horizontal, was bevorzugt ist.According to a further aspect of the invention, the movement device 4 which effects the laying movement is designed such that it comprises a pivotable element, which is in particular a pivotable arm 12 and in particular a pivotable telescopic arm 12, which is used to carry out the laying movement about an axis 11 the support structure 6 is pivotable. As can be seen from FIG. 1, the axis 11 is displaceable in parallel from the one side of the support structure to the other side of the support structure (along the line A), so that an extended area for the laying movement results. In the example, the shift is horizontal, which is preferred.

Figur 3 zeigt schematisch eine Ausführungsform ähnlich derjenigen der Figuren 1 und 2, wobei gleiche Bezugszeichen gleiche Elemente bezeichnen, und wobei in Figur 3 verschiedene Stellungen des längsverstellbaren Armes 12 dargestellt sind, nämlich eine Endstellung mit der geringsten Länge des ausfahrbaren Teleskoparmes 12 und eine Stellung, bei welcher der Teleskoparm voll ausgefahren ist. Entsprechend können verschieden grosse Tunnelprofile mit der Verlegevorrichtung bearbeitet werden.Figure 3 shows schematically an embodiment similar to that of Figures 1 and 2, wherein like reference numerals designate like elements, and wherein in Figure 3 different positions of the longitudinally adjustable arm 12 are shown, namely an end position with the smallest length of the telescopic telescopic arm 12 and a position, in which the telescopic arm is fully extended. Accordingly, different sized tunnel profiles can be processed with the laying device.

Figur 4 zeigt in Schnittdarstellung entlang der Linie F-F der Figuren 3 bzw. 5 eine bevorzugte Ausführungsform des der Tunnelwandung 3 zugewandten Endes der Bewegungseinrichtung 4, welche in diesem Fall wiederum einen längenverstellbaren Arm 12, und insbesondere einen Teleskoparm aufweist. Die Längenverstellung kann dabei pneumatisch, hydraulisch oder auch motorisch erfolgen. Am Ende des Teleskoparmes 12 ist ein Ausleger 20 fest angeordnet, an dessen freien Ende ein Hebel 21 um eine Achse 20' schwenkbar befestigt ist. Der Hebel 21 wiederum trägt an seinem anderen Ende die Aufnahme für die Folienrolle 5, welche Aufnahme bzw. Rolle eine Längsachse 26 aufweist. Die Rolle 5 ist in dieser Folienrollenaufnahme mit der Längsachse 26 drehbar gehalten, so dass die Folie als Bahn 15 von der Rolle 5 abziehbar ist. Über eine Umlenkung 27 gelangt die Folienbahn an mindestens eine Andruckrolle, welche die Folie an die Bauwerksfläche 3 andrückt. Im Beispiel von Figur 4 sind dabei mehrere Sätze von jeweils vier Andruckrollen 28 vorgesehen, wobei in der Darstellung von Figur 4 nur ein solcher Satz ersichtlich ist. Diese Sätze von Andruckrollen wirken jeweils in dem Bereich auf die Folie ein, in dem der Klebstoffauftrag erfolgt ist. Stangenförmige, koaxial mit der Rollenachse angeordnete Träger 55 und 56 bilden zusammen mit einem hinteren Schild 25 und einem vorderen Schild 25', welches in Figur 4 nicht ersichtlich ist, ein Tragelement, welches die Aufnahme mit der Längsachse 26 für die Rolle 5 bildet. Das Tragelement kann dabei so ausgebildet werden, dass eine volle Rolle 5 auf einfache Weise in das Tragelement eingehängt und daran drehbar befestigt werden kann. Das am Hebel 21 befestigte Tragelement wird dabei durch ein hydraulisches oder pneumatisches Anpresselement 24, welches am Arm 12 und am Hebel 21 abgestützt ist, gegen die Tunnelwandung gedrückt. Die Plattform 10 ist in diesem Beispiel ebenfalls am Ausleger 20 um die Achse 60 schwenkbar angeordnet, so das sie immer im wesentlichen horizontal bleibt. Die Plattform 10 kann bevorzugterweise als begehbare Arbeitsbühne ausgestaltet sein, so dass eine Überwachungsperson die Auftragung des Klebstoffes auf die Folienbahn und deren Aufbringung auf die wandung 3 überwachen kann. Das Aufbringen des Schmelzklebstoffes auf die Folienbahn 15 erfolgt in diesem Beispiel wiederum über eine mit der Bewegungseinrichtung mitgeführte Schmelzeinrichtung 7, deren Verbindung mit dem Schlauch 9 in der Figur 4 nicht dargestellt ist. Der gezeigte Aspekt der schwenkbaren und längenverstellbaren Bewegungseinrichtung wird dabei bevorzugterweise mit dem vorgängig erläuterten Aspekt des Mitführens der Schmelzeinrichtung kombiniert. Der Aspekt der schwenkbaren und längeneinstellbaren Bewegungseinrichtung kann indes auch mit herkömmlichen stationären Schmelzeinrichtungen kombiniert sein oder kann allenfalls sogar mit anderen Befestigungsmitteln als Klebstoff für die Folienbahn verwendet werden, z.B. mit Klettbefestigungsmitteln.FIG. 4 shows, in a sectional view along the line FF of FIGS. 3 and 5, a preferred embodiment of the end of the movement device 4 facing the tunnel wall 3, which in turn has a length-adjustable arm 12, and in particular a telescopic arm. The length adjustment can be done pneumatically, hydraulically or by motor. At the end of the telescopic arm 12, a boom 20 is fixed, at its free end a lever 21 about an axis 20 'is pivotally mounted. The lever 21 in turn carries at its other end the receptacle for the film roll 5, which receptacle or roller has a longitudinal axis 26. The roller 5 is rotatably held in this film roll receptacle with the longitudinal axis 26, so that the film is removable as a web 15 of the roller 5. Via a deflection 27, the film web reaches at least one pressure roller, which presses the film against the building surface 3. In the example of Figure 4, several sets of four pinch rollers 28 are provided, in the representation of Figure 4, only such a sentence is visible. These sets of pressure rollers each act in the area on the film in which the adhesive has been applied. Bar-shaped carriers 55 and 56 arranged coaxially with the roller axis form together with a rear plate 25 and a front plate 25 'which can not be seen in FIG is a support member which forms the receptacle with the longitudinal axis 26 for the roller 5. The support member may be formed so that a full roll 5 can be easily hooked into the support member and rotatably attached thereto. The support element attached to the lever 21 is pressed against the tunnel wall by a hydraulic or pneumatic pressure element 24, which is supported on the arm 12 and on the lever 21. The platform 10 is also pivotally mounted on the boom 20 about the axis 60 in this example so that it always remains substantially horizontal. The platform 10 may preferably be designed as a walk-on platform, so that a supervisor can monitor the application of the adhesive to the film web and its application to the wall 3. The application of the hotmelt adhesive to the film web 15 takes place in this example, in turn, a carried along with the moving device melting device 7, the connection with the hose 9 in Figure 4 is not shown. The aspect of the pivotable and length-adjustable movement device shown here is preferably combined with the previously explained aspect of entrainment of the melting device. However, the aspect of the pivotable and adjustable length motion means may also be combined with conventional stationary fusing means, or may even be used with other fastening means as an adhesive for the film web, eg with Velcro fasteners.

Anhand der Figuren 3 und 5-7 werden nun weitere bevorzugte Ausführungsformen der Vorrichtung bzw. des Verfahrens erläutert. Wie aus Figur 3 ersichtlich, ist die Bewegungseinrichtung 4 oberseitig an einem Portalwagen 6 angeordnet. Dieser weist Räder auf, mittels welchen er entlang des Tunnels verfahrbar ist. Auf diese Weise können die Folienbahnen nacheinander versetzt zueinander durch die Verlegebewegung auf die Tunnelwandung aufgebracht werden. Ein die Schwenkachse 11 tragender Wagen 35 der Bewegungseinrichtung ist dabei an der Oberseite der vom Portalwagen gebildeten Tragstruktur 6 vorzugsweise horizontal verfahrbar, um die Schwenkachse 11 verfahren zu können. In der Draufsicht von Figur 5 ist ersichtlich, dass das Verfahren der Schwenkachse 11 durch einen Wagen 35 bewirkt wird, welcher auf Schienen 39 auf der Tragstruktur 6 verfahrbar ist. In der Draufsicht von Figur 5 ist wiederum die am Arm 12 angeordnete Plattform 10 ersichtlich. In diesem Beispiel ist die Schmelzeinrichtung 7 ungefähr mittig auf der Plattform 10 angeordnet. Bei der Ausgestaltung als Arbeitsbühne können auf dieser Plattform 10 zwei Personen beidseits der Schmelzeinrichtung 7, welche bevorzugterweise auch den Gasvorrat umfasst und allenfalls Vorräte von Schmelzklebstoff umfasst, Platz finden. In dem gezeigten Beispiel ist an dem Arm 12 neben der Aufnahme für die Folienrolle auf der anderen Seite des Armes eine Bearbeitungseinrichtung zur Bearbeitung der Tunnelwandung angeordnet, welche nachfolgend noch genauer erläutert wird. Diese Arbeitseinrichtung weist Drahtbürsten 45 und/oder Fräser auf sowie eine Arbeitsbühne 33. Weiter ist in diesem Beispiel ersichtlich, dass an der Tragstruktur ein weiterer Wagen 61 vorgesehen sein kann, der vorzugsweise vom ersten Wagen unabhängig verfahrbar und welcher auf weiteren Schienen 63 verschieblich ist und eine Bewegungseinrichtung, vorzugsweise einen Arm 30 trägt. Dieser ist ebenfalls schwenkbar und längenverstellbar und trägt mindestens die Schweisseinrichtung 32, welche die gerade in Verlegung befindliche Folie 15 mit der bereits vorher verlegten Folie auf bekannte Weise verschweisst. Auch der Schweisseinrichtung 32 kann eine Arbeitsbühne 31 zugeordnet sein, welche ebenfalls vom Arm 30 getragen wird. Durch diese zweite Bewegungseinrichtung, die vorzugsweise unabhängig von der ersten Bewegungseinrichtung ist, kann die Verschweissung optimal auf die Verlegung abgestimmt werden.With reference to Figures 3 and 5-7 further preferred embodiments of the device and the method will now be explained. As can be seen from FIG. 3, the movement device 4 is arranged on the top side on a portal carriage 6. This has wheels, by means of which it is movable along the tunnel. In this way, the film webs can be successively offset from each other by the laying movement are applied to the tunnel wall. A the pivot axis 11 carrying car 35 of the movement device is preferably horizontally movable on the upper side of the support structure formed by the portal carriage 6 in order to be able to move the pivot axis 11. In the plan view of Figure 5 it can be seen that the method of the pivot axis 11 is effected by a carriage 35 which is movable on rails 39 on the support structure 6. In the plan view of Figure 5, in turn, the arranged on the arm 12 platform 10 can be seen. In this example, the melting device 7 is arranged approximately centrally on the platform 10. In the embodiment as a working platform, two persons on both sides of the melting device 7, which preferably also includes the gas supply and at most supplies of hot melt adhesive, can find space on this platform 10. In the example shown, a processing device for processing the tunnel wall is arranged on the arm 12 next to the receptacle for the film roll on the other side of the arm, which will be explained in more detail below. This working device has wire brushes 45 and / or cutters and a working platform 33. Furthermore, it can be seen in this example that a further carriage 61 can be provided on the support structure, which is preferably movable independently of the first carriage and which is displaceable on further rails 63 and a movement device, preferably an arm 30 carries. This is also pivotable and adjustable in length and carries at least the welding device 32, which welds the currently in the process of laying film 15 with the previously laid film in a known manner. Also, the welding device 32 may be associated with a working platform 31, which is also supported by the arm 30. By this second movement means, which is preferably independent of the first movement means, the welding can be optimally adapted to the installation.

Bevorzugterweise ist die Lage der Längsachse 26 der Aufnahmeeinrichtung für die Folienrolle nicht nur durch die Verlegebewegung entlang der Bauwerksfläche bzw. Tunnelwandung 3 bewegbar, sondern auch in ihrer Lage zu der Wandung 3 einstellbar. Diese Einstellung umfasst eine Schwenkbewegung und/oder eine Neigebewegung der Längsachse 26 der Folienrollenaufnahme. Betrachtet man dazu Figur 4 und denkt sich dazu die horizontal verlaufende Ebene B, die durch die Achse 26 verläuft, so liegt die Längsachse 26 der Rollenaufnahme in dieser Ebene und zwar parallel zu der Schnittlinie aus der Ebene B mit der Tunnelwandung 3. Damit bei der Verlegebewegung Korrekturen der Folienbahn und eine gleichmässige Überlappung mit der vorherigehenden Folienbahn auch bei einem Kurvenverlauf des Tunnels durchführbar sind, so ist die Längsachse 26 zunächst in der Ebene B so verschwenkbar, dass die Längsachse in verschwenkter Stellung nicht parallel zur Schnittlinie der Ebene B mit der wandung 3 verläuft. Eine zusätzliche bevorzugte Korrekturmöglichkeit besteht darin, dass die Längsachse 26 so geneigt wird, dass die Längsachse 26 nicht mehr in der Ebene B liegt, sondern zu dieser geneigt verläuft, so dass das eine Ende der Achse über und das andere Ende der Achse unter der Ebene B liegt und die Achse 26 geometrisch gesehen nur noch einen Punkt mit der Ebene B gemeinsam hat. Diese Verstellmöglichkeiten der Achse 26 können bei der Rollenaufnahme selber vorgesehen sein, werden aber in dem gezeigten Beispiel und bevorzugterweise am anderen Ende der Bewegungseinrichtung 4 bei deren Lagerung an der Tragstruktur 6 bzw. dem Portalwagen ausgeführt. Figur 13 zeigt die entsprechende Lagerung der Bewegungseinrichtung 4 mit dem Arm 12, der die Achse 26 trägt in grob schematischer Darstellung in Ansicht von oben. Ersichtlich ist der Wagen 35 mit der Schwenkachse 11 für den Arm 12. Die Stellung des Arms ist z.B. ebenfalls im wesentlichen horizontal und die Achse 26 liegt in der Horizontalebene B. In der gezeigten Normalstellung des Wagens 35 zu der Ebene B liegt die Achse 26 in der Ebene B und verläuft parallel zur Schnittlinie der Ebene B mit dem Tunnelgewölbe 2. Wird nun der Wagen 35 um eine Achse 48, die senkrecht zur Ebene B steht gedreht, so bewegt sich das Ende des Armes 4, das die Längsachse 26 trägt entlang der Kreislinie C und die Achse 26 (mit der Folienrolle) schwenkt in der Ebene B derart, dass sie nicht mehr parallel zur Schnittlinie der Ebene B mit der Tunnelwandung 2 steht.Preferably, the position of the longitudinal axis 26 of the receiving means for the film roll is not only movable by the laying movement along the building surface or tunnel wall 3, but also in their position to the wall 3 adjustable. This setting comprises a pivoting movement and / or a tilting movement of the longitudinal axis 26 of the film roll receptacle. If you look at Figure 4 and thinks to the horizontally extending plane B, which passes through the axis 26, so is the longitudinal axis 26 of the roller mount in this plane and parallel to the section line from the plane B with the tunnel wall 3. So in the Laying movement corrections of the film web and a uniform overlap with the preceding film web are also feasible in a curve of the tunnel, the longitudinal axis 26 is initially pivotable in the plane B so that the longitudinal axis in the pivoted position is not parallel to the section line of the plane B with the wall 3 runs. An additional preferred possibility of correction is that the longitudinal axis 26 is inclined so that the longitudinal axis 26 is no longer in the plane B, but extends inclined thereto, so that the one end of the axis above and the other end of the axis below the plane B is located and the axis 26 has geometrically only one point with the plane B in common. This adjustment of the axis 26 may be provided in the role recording itself, but are performed in the example shown and preferably at the other end of the moving means 4 during their storage on the support structure 6 and the portal car. FIG. 13 shows the corresponding mounting of the movement device 4 with the arm 12, which carries the axis 26 in a roughly schematic representation in a view from above. The position of the arm is, for example, likewise essentially horizontal and the axis 26 lies in the horizontal plane B. In the normal position of the carriage 35 to the plane B, the axis 26 lies in FIG the plane B and runs parallel to the intersection of the plane B with the tunnel arch 2. Now, the carriage 35 by one Axis 48, which is perpendicular to the plane B is rotated, so moves the end of the arm 4, which carries the longitudinal axis 26 along the circular line C and the axis 26 (with the film roll) pivots in the plane B such that they are no longer parallel to the intersection of the plane B with the tunnel wall 2 stands.

Wird andererseits der Wagen 35 um die Achse 38 geschwenkt, die in diesem Beispiel in der Ebene B liegt und durch die Mitte M der Längsachse 26 verläuft, was nicht zwingend ist, so verlässt die Längsachse 26 die Ebene B ausgenommen im Mittelpunkt M; die Längsachse 26 wird somit zur Ebene B geneigt bzw. gekippt. Vorzugsweise sind beide Verstellmöglichkeiten vorgesehen. Eine konstruktive Ausgestaltung ist in den Figuren 5, 6 und 7 ersichtlich. So sind die Schienen 39 für den Wagen 35 (Figur 5) an einem inneren Tragelement 37 befestigt, welches um die Schwenkachse 38 schwenkbar an einem äusseren Tragelement 36 befestigt ist. Dies ist im Detail in den Schnittdarstellungen E-E (Figur 6) und D-D (Figur 7) ersichtlich. Die Pfeile D stellen dabei die Neigung der Schienen 39 zur oberen Horizontalebene der Tragstruktur dar, welche zu einer entsprechenden Neigung der Bewegungseinrichtung mit dem Arm 12 führt, was zu der erwähnten Neigebewegung der Längsachse 26 aus der Ebene B herausführt. Diese Bewegung des Tragelementes 37 um die Achse 38 kann z.B. durch nicht dargestellte Elektromotoren bewirkt werden. Die vorerwähnte Schwenkung der Längsachse 26 der Folienrollenaufnahme in der Ebene B wird andererseits durch eine Drehung der Schienen 39 um die Achse 48 bewirkt, die vorzugsweise senkrecht zur Horizontalebene der Tragstruktur 6 steht. Zu diesem Zweck sind die Schienen 39 auf einer Drehbühne 42 angeordnet, welche um die Achse 48 drehbar am Tragelement 37 angeordnet ist, wie dies aus den Figuren 6 und 7 ersichtlich ist. Die Schienen 63 für den Wagen 61, der den Arm 30 trägt, sind vorzugsweise auf dieselbe geschilderte Weise verstellbar, wie die Schienen 39, so dass die Schweisseinrichtung 32 automatisch der Verstellung der Längsachse 26 der Folienrollenaufnahme folgt. Für diese Bewegung sind die beiden Bewegungseinrichtungen also vorzugsweise gekoppelt, während sie, wie erwähnt, für das Verfahren und Schwenken unabhängig sind.On the other hand, when the carriage 35 is pivoted about the axis 38, which in this example lies in the plane B and passes through the center M of the longitudinal axis 26, which is not mandatory, the longitudinal axis 26 leaves the plane B except in the center M; the longitudinal axis 26 is thus inclined or tilted to the plane B. Preferably, both adjustment options are provided. A structural design is shown in Figures 5, 6 and 7. Thus, the rails 39 for the carriage 35 (Figure 5) are secured to an inner support member 37 which is pivotally mounted about the pivot axis 38 on an outer support member 36. This can be seen in detail in the sectional views EE (FIG. 6) and DD (FIG. 7). The arrows D represent the inclination of the rails 39 to the upper horizontal plane of the support structure, which leads to a corresponding inclination of the movement means with the arm 12, which leads to the mentioned tilting movement of the longitudinal axis 26 from the plane B. This movement of the support member 37 about the axis 38 can be effected for example by electric motors, not shown. The aforementioned pivoting of the longitudinal axis 26 of the film roll receptacle in the plane B is on the other hand effected by a rotation of the rails 39 about the axis 48, which is preferably perpendicular to the horizontal plane of the support structure 6. For this purpose, the rails 39 are arranged on a rotating platform 42, which is arranged rotatably about the axis 48 on the support member 37, as can be seen from Figures 6 and 7. The rails 63 for the carriage 61, which carries the arm 30, are preferably adjustable in the same way as the rails 39, so that the welding device 32 automatically follows the adjustment of the longitudinal axis 26 of the film roll holder. For this movement, the two movement devices are thus preferably coupled, while, as mentioned, they are independent of the method and pivoting.

Die Figur 8 zeigt in Draufsicht von oben eine vergrösserte Darstellung des vorderen Endes der Bewegungseinrichtung mit den Arbeitsbühnen 10, 33 und auch 31. Es sind nicht alle Elemente der Folienführung dargestellt, ersichtlich sind aber die nebeneinanderliegenden mehreren Sätze von Andruckrollen 28 und entsprechend auch von rotierenden Drahtbürsten 45, welche die Wandung 3 bei der Verlegebewegung für die eine Folienbahn bereits an den Stellen vorbearbeiten, bei denen die Schmelzklebstoffraupen bei der Verlegung der nächsten Folienbahn zu liegen kommen. Anstelle oder zusätzlich zu den Drahtbürsten können auch Fräselemente vorgesehen sein, besonders bei sehr unebenen Tunnelwandungen. Figur 9 zeigt eine entsprechende Ansicht von der Tunnelwandung her auf die Bewegungseinrichtung hin gesehen, worin wiederum die Sätze von Andruckrollen 28 ersichtlich sind sowie auch in dieser Figur die entsprechend angeordneten Ausbringköpfe 17 für den flüssigen Schmelzklebstoff. Ersichtlich ist in dieser Figur auch die Aufnahmestruktur für die nur angedeutete Folienrolle 5, welche durch die Schilde 25 und 25' mit den Verbindungsstangen 55 und 56 gebildet wird, und die Längsachse 26 für die Folienrollenaufnahme bildet. Ersichtlich sind ferner wiederum die Drahtbürsten 45, welche im gleichen Abstand wie die Andruckrollensätze bzw. die Ausbringköpfe 10 voneinander beabstandet angeordnet sind. Die Figuren 10 und 11 zeigen entsprechende Schnittdarstellungen entsprechend den Schnittlinien A-A und B-B von Figur 9, in welchen dieselben Elemente noch einmal ersichtlich sind. Zusätzlich zu den rotierenden Runden Drahtbürsten 45 können lineare Drahtbürsten 46' vorgesehen sein. Vor dem Aufbringen des Schmelzklebstoffes können die Aufbringstellen wenn nötig durch eine Trocknungseinrichtung getrocknet werden.Figure 8 shows in plan view from above an enlarged view of the front end of the movement device with the working platforms 10, 33 and 31. Not all elements of the film guide are shown, but it can be seen the juxtaposed several sets of pinch rollers 28 and accordingly also of rotating Wire brush 45, which already pre-work the wall 3 in the laying movement for a film web at the points where the hot melt adhesive beads come to rest when laying the next sheet. Instead of or in addition to the wire brushes and cutting elements may be provided, especially for very uneven tunnel walls. FIG. 9 shows a corresponding view from the tunnel wall on the movement device, which in turn shows the sets of pressure rollers 28 as well as in this figure the correspondingly arranged application heads 17 for the liquid hotmelt adhesive. It can be seen in this figure, the receiving structure for the only indicated film roll 5, which is formed by the shields 25 and 25 'with the connecting rods 55 and 56, and forms the longitudinal axis 26 for the film roll holder. Also visible are, in turn, the wire brushes 45, which are arranged at the same distance as the Andruckrollensätze or the Ausbringköpfe 10 spaced from each other. Figures 10 and 11 show corresponding sectional views corresponding to the section lines AA and BB of Figure 9, in which the same elements are shown again. In addition to the rotating round wire brushes 45, linear wire brushes 46 'may be provided. Before applying the hot melt adhesive If necessary, the application points can be dried by a drying device.

Figur 12 zeigt eine weitere Ausführungsform, bei welcher die Schmelzeinrichtung nicht auf einer begehbaren Plattform mitgeführt wird, so dass separate Podeste 70 und 71 an der Tragstruktur 6 vorgesehen sind.FIG. 12 shows a further embodiment in which the melting device is not carried on a walk-on platform, so that separate platforms 70 and 71 are provided on the support structure 6.

Figur 5 zeigt weiter eine bevorzugte Ausgestaltung der Räder des Portalwagens 6, wobei diese Räder 67 aus einer Arbeitsstellung in eine Transportstellung 67' schwenkbar sind, wobei die Drehrichtung des Rades beibehalten wird. Dies erlaubt einen einfacheren Transport der Vorrichtung. Zum Transport ist ferner der Portalwagen bzw. die Tragstruktur in ihrer Höhe reduzierbar. In Figur 3 ist das durch die ineinanderschiebbare Ausgestaltung der Säulen der Tragstruktur 6 mit den Elementen 66 und 68 dargestellt. Weiter werden zum Transport die Bewegungseinrichtungen gegenüber der in Figur 5 ersichtlichen Stellung um 90° gedreht, so dass die Arme 12 und 34 in Längsrichtung der Tragstruktur zu liegen kommen. Auf diese Weise kann ein einfacher Transport der ganzen Vorrichtung erfolgen.Figure 5 also shows a preferred embodiment of the wheels of the portal trolley 6, said wheels 67 are pivotable from a working position into a transport position 67 ', wherein the direction of rotation of the wheel is maintained. This allows a simpler transport of the device. For transport, the portal trolley or the support structure can also be reduced in height. In FIG. 3 this is illustrated by the telescoping configuration of the columns of the support structure 6 with the elements 66 and 68. Furthermore, the movement devices are rotated by 90 ° relative to the position shown in FIG. 5 for transport, so that the arms 12 and 34 come to rest in the longitudinal direction of the support structure. In this way, a simple transport of the entire device can take place.
