Description
Die Erfindung bezieht sich auf ein Handarbeitsgerät, insbesondere zum
Durchtrennen eines Metallklipses in einem Mauerwerk, nach dem Oberbegriff des
Patentanspruches 1. Ein solches Gerät ist z.B. aus
der EP-A-0 756 920 bekannt.The invention relates to a hand tool, in particular for
Cutting a metal clip in a masonry, according to the preamble of
Insbesondere bei Altbausanierungen müssen die Fensterrahmen zu
Renovierungszwecken aus dem Mauerwerk entfernt werden, so daß die die
Fensterrahmen arretierenden Metallklipse zu durchtrennen sind.
Dazu werden üblicherweise Handarbeitsgeräte der vorgenannten Art eingesetzt,
mittels denen Nuten in das Mauerwerk gefräst werden, um die Metallklipse zu lösen.
Das Eindringen der Frässcheibe in das Mauerwerk verursacht hierbei eine große
Verschmutzung, da der Mörtelstaub durch die Rotation der Frässcheibe
unkontrolliert in die Umgebung geschleudert wird.In particular, in Altbausanierungen the window frames must be removed for renovation purposes of the masonry, so that the window frames arresting metal clips are to be cut.
For this purpose, hand tools of the aforementioned type are usually used, by means of which grooves are milled into the masonry to solve the metal clips. The penetration of the milling disc in the masonry here causes a large contamination, since the mortar dust is thrown uncontrollably in the environment by the rotation of the milling disc.
Aus der EP 0 579 964 A1 ist eine Handsäge mit einer Absaugvorrichtung bekannt, mittels der der anfallende Staub aufgenommen und in einen Sammelbehälter geleitet wird.EP 0 579 964 A1 discloses a hand saw with a suction device, taken by the accumulating dust and passed into a collection container becomes.
Als nachteilig bei diesem Stand der Technik hat es sich gezeigt, daß das zu bewegende Werkzeug offen an dem zu bearbeitenden Werkstück anliegt, so daß aufgrund der Linearbewegung des Werkzeuges der dadurch anfallende Staub von dem Ansaugkanal weggeschleudert wird; somit kann nur ein gewisser Anteil des anfallenden Staubes aufgesaugt werden.A disadvantage of this prior art, it has been shown that to moving tool is open to the workpiece to be machined, so that due to the linear movement of the tool resulting from the dust of is thrown away the intake duct; Thus, only a certain proportion of the absorbed dust.
Des weiteren ist zusätzlich zu den üblichen Bauteilen der Handsäge ein Absaugkanal vorzusehen, mittels dem der anfallende Staub aufgenommen werden soll. Diese weiteren Bauteile erhöhen jedoch die Gewichtskraft der Handsäge, so daß beispielsweise Arbeiten über Kopf nur schwer und zeitlich begrenzt ausführbar sind.Furthermore, in addition to the usual components of the hand saw To provide suction, by means of which the accumulated dust can be absorbed should. However, these other components increase the weight of the hand saw, so that, for example, work overhead is difficult and time-limited executable are.
Für Arbeiten zum Lösen von Fensterrahmen ist die bekannte Handsäge nicht einsetzbar, da diese eine Linearbewegung vollzieht; das Handarbeitsgerät zum Lösen von Fensterrahmen aus Mauerwerken jedoch eine Rotationsbewegung ausführen sollte, da nur mittels einer Rotationsbewegung eine gleichmäßige lineare Führung des Handarbeitsgerätes entlang des Fensterrahmens gewährleistet ist.For work to solve window frames, the well-known hand saw is not can be used, since this performs a linear movement; the hand tool to Solving masonry window frames, however, a rotational movement should perform, since only by means of a rotary motion, a uniform linear Guiding the hand tool along the window frame is guaranteed.
Aus der FR 1.231.379 ist ebenfalls ein Handarbeitsgerät mit einer Frässcheibe, die in einem Gehäuse des Handarbeitsgerätes angeordnet ist, bekannt. Das Gehäuse der Frässcheibe kann in Umfangsrichtung von dieser geklappt werden. Seitlich neben dem Austritt der Frässcheibe ist an dem Gehäuse eine Auflagefläche vorgesehen, die folglich seitlich von diesem absteht.From FR 1.231.379 is also a hand tool with a milling disc, the is arranged in a housing of the hand tool, known. The housing the milling disc can be folded in the circumferential direction of this. Laterally in addition to the outlet of the milling disc is on the housing a bearing surface provided, which consequently protrudes laterally from this.
Aus der DE-OS 28 38 233 ist ein Handarbeitsgerät bekannt, das eine in einem Gehäuse des Handarbeitsgerätes gelagerte Frässcheibe aufweist. Die Frässcheibe tritt dabei an einer Stirnseite des Gehäuses aus diesem heraus. Das Handarbeitsgerät dient dazu, Nuten herzustellen, in denen Verbindungsstücke mit zwei aneinander angrenzenden Kreisabschnitten aufgenommen werden sollen.From DE-OS 28 38 233 a manual working device is known which has a in a Housing of the hand tool mounted milling disc has. The milling disc occurs at an end face of the housing out of this. The Hand tool is used to produce grooves in which connectors with two adjacent circular sections are to be included.
Zum Durchtrennen von in Mauerwerken angeordneten Metallklipsen ist dieses Handarbeitsgerät nicht geeignet, da der Abstand zwischen der aus dem Gehäuse herausragenden Frässcheibe und der unteren Auflagefläche des Gehäuses sehr groß ausgebildet ist, so dass die in das Mauerwerk einzuarbeitende Nut zur Durchtrennung der Metallklipse mit einem großen Abstand zu dem Fenster- oder Türrahmen verläuft. Oftmals ist jedoch der Abstand zwischen der beginnenden Fensterscheibe und dem Fenster- bzw. Türrahmen wesentlich geringer als der Abstand zwischen der Frässcheibe und der unteren Platte des Gehäuses. Aus diesen Gründen kann dieses Handarbeitsgerät zum Heraustrennen von in Mauerwerken eingearbeiteten Metallklipsen nicht verwendet werden.For cutting through arranged in masonry metal clips this is Hand tool not suitable as the distance between the out of the case outstanding milling disc and the lower bearing surface of the housing very is formed large, so that to be incorporated into the masonry groove for Separation of the metal clips with a large distance to the window or Door frame runs. Often, however, the distance between the beginning Window pane and the window or door frame much lower than the Distance between the cutter disc and the lower plate of the housing. Out For these reasons, this crafting tool can be used for cutting out in Masonry incorporated metal clips are not used.
Es ist daher Aufgabe der Erfindung, das Handarbeitsgerät der vorgenannten Gattung
derart weiterzubilden, daß es ermöglicht wird, Fensterrahmen aus dem Mauerwerk
zu lösen, ohne daß der dabei anfallende Schmutz in die Umgebung gelangt.
Das Handarbeitsgerät soll außerdem handlich und einfach zu bedienen sein, so daß
die Arbeiten zuverlässig und schnell durchgeführt werden können.
Des weiteren soll mittels des erfindungsgemäßen Handarbeitsgerätes eine
Anpassung an unterschiedliche Abstände zwischen der beginnenden Glasscheibe
und dem Fenster- oder Türrahmen möglich sein, so dass das Handarbeitsgerät
unabhängig von dem Abstand der Nut zu den Fenster- und Türrahmen an diesen
geführt werden kann.It is therefore an object of the invention to develop the hand tool of the aforementioned type such that it is possible to solve window frames from the masonry without the accumulating dirt gets into the environment.
The hand tool should also be handy and easy to use, so that the work can be done reliably and quickly.
Furthermore, an adaptation to different distances between the incipient glass pane and the window or door frame should be possible by means of the hand tool according to the invention, so that the manual working device can be guided independently of the distance of the groove to the window and door frames.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden
Teils des Patenanspruches 1 gelöst.This object is achieved by the features of the characterizing
Part of the
Darüber hinaus ist im Bereich der Austrittsöffnung am Gehäuse ein Anlagesteg angebracht, der eine senkrecht zur Austrittsöffnung verlaufende Anlagefläche aufweist. Somit sind im Bereich der Austrittsöffnung zwei rechtwinkelig zueinander angeordnete Führungsebenen vorgesehen, die dazu dienen, daß das Handarbeitsgerät positionsgenau am Fensterrahmen und am Mauerwerk entlang geführt werden kann.In addition, in the region of the outlet opening on the housing is a contact bar attached, which extends perpendicular to the outlet bearing surface having. Thus, two perpendicular to each other in the region of the outlet opening arranged guide levels provided, which serve that the Hand tool with precise position on the window frame and along the masonry can be performed.
Die Höheneinstellung der Anlageplatte wird dadurch bewerkstelligt, dass diese an zwei im Gehäuse gelagerten Gewindespindeln gehalten ist und dass die beiden Gewindespindeln mittels eines Verbindungsstiftes formschlüssig miteinander in Wirkverbindung stehen. Darüber hinaus ist an einer der beiden Gewindespindeln eine aus dem Gehäuse ragende Verstellschraube zur Höhenverstellung der Auflageplatte vorgesehen, die in dem Gehäuse des Handarbeitsgerätes gelagert ist.The height adjustment of the contact plate is accomplished by applying these held in the housing two threaded spindles and that the two Threaded by means of a connecting pin form fit together Active compound stand. In addition, on one of the two threaded spindles a protruding from the housing adjusting screw for height adjustment of Platen provided, which is mounted in the housing of the crafting device.
Zur Bewegung zumindest eines Gehäuseteiles gegenüber der fest an dem Handarbeitsgerät angebrachten Frässcheibe ist das Gehäuse zweiteilig ausgebildet, wobei der erste Gehäuseteil fest mit dem Handarbeitsgerät verbunden ist und der zweite Gehäuseteil relativ zu dem ersten Gehäuseteil verstellbar ist.For moving at least one housing part relative to the fixed to the Hand tool attached milling disc, the housing is formed in two parts, wherein the first housing part is firmly connected to the hand tool and the second housing part is adjustable relative to the first housing part.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the Dependent claims.
Der Erfindungsgegenstand ermöglicht vorteilhafterweise, daß handelsübliche
Handarbeitsgeräte, wie beispielsweise eine Flex oder Fräsmaschine, zum Lösen von
in Mauerwerken eingeputzten Metallklipsen eingesetzt werden können, ohne daß
durch die Rotation der Frässcheibe der Mörtel in die Umgebung ausgestoßen wird
und somit unangenehme Verunreinigungen entstehen.
Der Teil der Frässcheibe, der nicht in das Mauerwerk eindringt, ist nämlich
vollständig von dem Gehäuse umschlossen, so daß der Mörtel bzw. der Staub durch
das Gehäuse aufgefangen wird und nicht in die Umgebung gelangt. Aufgrund der
Rotation der Frässcheibe entsteht nämlich innerhalb des Gehäuses ein Luftstrom,
der den Mörtel definiert in Richtung des Auslaßkanals mitnimmt.
Der-Auslaßkanal endet in einer Sammelkammer, in der der Mörtel bis zum Entleeren
aufbewahrt werden kann.
Somit gelangt der Mörtel und dessen Staub kontrolliert in die Sammelkammer, so
daß das Durchtrennen der den Fensterrahmen arretierende Meiallklipse mit dem
Handarbeitsgerät ohne nennenswerte Verschmutzung der Umgebung durchführbar
ist.The subject invention advantageously allows commercial hand tools, such as a flex or milling machine, can be used to solve plastered in masonry metal clips without the mortar is ejected by the rotation of the milling disc into the environment and thus inconvenient contamination.
The part of the milling disc, which does not penetrate into the masonry, namely, completely enclosed by the housing, so that the mortar or the dust is collected by the housing and does not get into the environment. Due to the rotation of the milling disc, an air flow, which defines the mortar in the direction of the outlet channel, is created inside the housing.
The outlet ends in a collection chamber in which the mortar can be stored until emptying.
Thus, the mortar and its dust passes controlled in the collection chamber, so that the severing of the window frame arresting Meiallklipse with the hand tool without significant pollution of the environment is feasible.
Darüber hinaus dient die Außenwandung des Gehäuses als Führungsglied und die Anlagefläche bildet hierzu einen rechten Winkel, so daß das Handarbeitsgerät exakt zwischen dem Mauerwerk und dem Fensterrahmen angesetzt werden kann und demnach einen senkrecht verlaufenden Einschnitt in das Mauerwerk zu bewerkstelligen ist, so daß entlang des Fensterrahmens und so nahe wie möglich an diesem eine Trennung des Metallklipses innerhalb des Mauerwerkes erfolgt, wodurch der renovierte oder neue Fensterrahmen in die ursprüngliche Fensteraussparung wieder einsetzbar ist, ohne daß umfangreiche Verputzungsarbeiten bzw. Anpassungen notwendig sind.In addition, the outer wall of the housing serves as a guide member and the Contact surface forms a right angle, so that the hand tool exactly between the masonry and the window frame can be attached and Accordingly, a vertical incision in the masonry is done so that along the window frame and as close as possible to this a separation of the metal clip takes place within the masonry, making the renovated or new window frame into the original one Window recess can be used again without extensive Plastering or adjustments are necessary.
Bei insbesondere älteren Fenstern ist es denkbar, dass der Abstand zwischen der Glasscheibe und dem Fenster- bzw. Türrahmen unterschiedlich breit ausgebildet ist, so dass, um ein optimales erneutes Einsetzen des Fenster- bzw. Türrahmens in die ursprüngliche Fensteraussparung nur dadurch bewerkstelligt werden kann, wenn der Schnitt, also die Durchtrennung der Metallklipse in dem Mauerwerk an einer exakt vorgegebenen Stelle durchgeführt wird. Gleichzeitig soll aber auch die untere Platte des Gehäuses entlang des Fenster- bzw. Türrahmens axial geführt werden können. Um dies nunmehr zu gewährleisten, ist es vorteilhaft, eine Anlageplatte vorzusehen, die sich einerseits an dem Fenster- bzw. Türrahmen abstützen kann und andererseits höhenverstellbar am Gehäuse angebracht ist. Mit einer solchen Anlageplatte und deren konkreten Höhenverstellung an dem Gehäuse des Handarbeitsgerätes kann der Abstand zwischen der unteren Platte des Gehäuses und dem Fensterrahmen höhenverstellbar eingestellt werden. In particular older windows, it is conceivable that the distance between the Glass pane and the window or door frame is designed to be different widths, so that, to an optimal re-insertion of the window or door frame in the original window recess can be accomplished only if the Cut, so the separation of the metal clips in the masonry at a precise is carried out in the prescribed place. At the same time but also the lower plate of the housing along the window or door frame can be axially guided. To ensure this now, it is advantageous to provide a bearing plate, on the one hand can be supported on the window or door frame and on the other hand height adjustable mounted on the housing. With such Investment plate and their concrete height adjustment to the housing of the Hand tool may be the distance between the lower plate of the housing and the window frame can be adjusted in height.

Sobald die Frässcheibe 11 in den Putz 4 eindringt, entstehen Staub, Mörtel und
ähnliche Verschmutzungen, die durch die Rotation der Frässcheibe 11 in das
Gehäuse 12 geschleudert werden und dort mittels der durch die Drehung der
Frässcheibe 11 herrschenden Umluft in den der Hauswand 3 gegenüberliegenden
Bereich des Gehäuses 12 bewegt werden.
Da sich in diesem Bereich des Gehäuses 12 ein Auslaßkanal 16 befindet, werden
die Staubpartikel des Putzes 4 mittels des Umluftstromes der Frässcheibe 11 hinaus
befördert. Am Ende des Auslaßkanals 16 ist eine nicht dargestellte Sammelkammer
angeordnet; dies kann beispielsweise ein Plastiksack sein, in dem der Mörtel und die
Staubpartikel kontrolliert aufgefangen werden.As soon as the
Since there is an
Die Frässcheibe 11 weist zentrisch eine Senkbohrung 17 auf, durch die eine mit
einem Außengewinde versehene Senkschraube 19 durchgreift. In den
Antriebsflansch 9 ist ebenfalls zentrisch eine Gewindebohrung 18 eingearbeitet, in
die die Senkschraube 19 zur Befestigung der Frässcheibe 11 eingedreht ist. Die
Oberflächen der Senkschraube 19 und der Frässcheibe 11 sind im montierten
Zustand somit plan zueinander, so daß lediglich ein kleiner Luftspalt zwischen der
der Senkschraube 19 zugewandten Wand des Gehäuses 12 und der Frässcheibe 11
entsteht.
Des weiteren sind an der Frässcheibe 11 zwei Scherstifte 20 angebracht, die in
seitlich neben der Gewindebohrung 18 des Antriebsflansches 9 eingearbeitete
Bohrungen eingesetzt sind, um die Frässcheibe 11 mit dem Antriebsflansch 9
trieblich zu verbinden. The
Furthermore, two
Ein an dem Gehäuse 12 im Bereich der Austrittsöffnung 15 angeformter Anlagesteg
21 dient als Anlagefläche 22, die auf die Oberfläche des Putzes 4 aufsetzbar ist. Des
weiteren ist die dem Antriebsflansch 9 gegenüberliegende Außenwandung des
Gehäuses 12 plan ausgebildet, so daß diese Fläche als Führungsglied 23 am
Fensterrahmen 2 einsetzbar und somit gewährleistet ist, daß das Handarbeitsgerät 1
entlang des gesamten Fensterrahmens 2 exakt positioniert bewegt werden kann, da
die Anlagefläche 22 und das Führungsglied 23 senkrecht zueinander stehen und
demnach gleichzeitig an dem Fensterrahmen 2 und dem Putz 4 anliegen.
Die Frässcheibe 11 dringt folglich senkrecht in den Putz 4 ein, so daß ein sauberer
gleichmäßiger Einschnitt entsteht.An integrally formed on the
The
Aus den Figuren 1 und 2 sind die beiden unterschiedlichen Positionen der
Frässcheibe 11 in bezug auf das Gehäuse 12 zu entnehmen, nämlich einerseits die
Ruheposition und andererseits die Arbeitsposition der Frässcheibe 11.
In der Ruheposition befindet sich die Frässcheibe 11 in dem Gehäuse 12,
wohingegen die Arbeitsposition dadurch gekennzeichnet ist, daß die Frässcheibe 11
etwa drei bis fünf Zentimeter aus dem Gehäuse 12 herausragt. In der Arbeitsposition
ist demnach gewährleistet, daß die Frässcheibe 11 den im Putz 4 befindlichen
Metallklips 5 durchschneiden kann.From Figures 1 and 2, the two different positions of the
In the rest position, the
Es ist jedoch auch möglich, daß das Gehäuse 12 im Bereich der Austrittsöffnung 15
verkleinert wird, so daß die Frässcheibe 11 in diesem Bereich mit der gewünschten
Eindringtiefe aus dem Gehäuse 12 ragt.However, it is also possible that the
Falls die Frässcheibe 11 gemäß dem Ausführungsbeispiel der Figuren 1, 2 und 3 in
der Ruheposition vollständig in dem Gehäuse 11 angeordnet ist, ist es notwendig,
daß zumindest Teile des Gehäuses 12 derart verstellt werden können, daß die
Frässcheibe 11 in der Arbeitsposition teilweise aus dem Gehäuse 12 übersteht.
Zu diesem Zweck ist das Gehäuse 12 zweiteilig ausgebildet, und zwar besteht das
Gehäuse 12 aus einem fest am Handarbeitsgerät 1 angebrachten ersten
Gehäuseteil 13 und einem relativ zu dem ersten Gehäuseteil 13 und somit auch zu
der Frässcheibe 11 verstellbaren zweiten Gehäuseteil 14. If the
For this purpose, the
Insbesondere der Figur 2 ist zu entnehmen, daß das erste Gehäuseteil 13 mittels
eines Haltebügels 28 an dem Handarbeitsgerät 1 fest angebracht ist. Zentrisch in
dem Gehäuseteil 13 ist dazu eine Bohrung vorgesehen, durch die der
Antriebsflansch 9 hindurchgeführt und somit vom Gehäuseteil 13 vollständig
umschlossen ist.
Senkrecht zu und seitlich neben dieser Bohrung sind in das Gehäuseteil 13 zwei
Führungsabschnitte 26 vorgesehen, die jeweils einen am zweiten Gehäuseteil 14
fest arretierten Führungsstift 27 aufnehmen. Die Führungsstifte 27 gleiten demnach
in den beiden Führungsabschnitten 26 in Verstellrichtung des zweiten Gehäuseteiles
14.In particular, the figure 2 it can be seen that the
Perpendicular to and laterally beside this bore, two
Zwischen dem ersten und dem zweiten Gehäuseteil 13 und 14 sind zwei Federn 29
angeordnet, die beim Herausdrücken der Frässcheibe 11 auf Zug belastet werden
und somit das zweite Gehäuseteil 14 nach Beendigung des Arbeitsvorganges wieder
in die Ruheposition zurückführen.
Gemäß Figur 2 sind die Federn 29 an den Führungsstiften 27 zwischen dem ersten
Gehäuseteil 13 und dem zweiten Gehäuseteil 14 angebracht.
In Figur 3 sind die Federn 29 dagegen seitlich neben dem Gehäuseteil 13 und den
Führungsstiften 27 angeordnet. Darüber hinaus bilden die einander zugekehrten
Stirnflächen der beiden Gehäuseteile 13 und 14 einen Anschlag, so daß die
Bewegungsfreiheit des zweiten Gehäuseteiles 14 begrenzt ist.Between the first and the
According to FIG. 2, the
In contrast, in FIG. 3, the
Das zweite Gehäuseteil 14 besteht aus einer oberen die Führungsstifte
aufnehmenden Platte 24 und einer unteren Platte 25, die im Bereich der
Austrittsöffnung 15 als Führungsglied 23 ausgebildet ist.
Die untere Platte 25 ist mittels zweier Stellschrauben 30 an der oberen Platte 24
befestigt. Zwischen den beiden Platten 24 und 25 können im Bereich der
Stellschraube 30 - nicht dargestellte - Abstandshalter eingesetzt werden, so daß sich
der Abstand zwischen den beiden Platten 24 und 25 zur Aufnahme von
unterschiedlich dicken Frässcheiben 11 beliebig einstellen läßt.The
The
Insbesondere die obere Platte 24 weist im Bereich des Antriebsflansches 9 eine
Trennebene auf, um die Frässcheibe 11 schnell wechseln zu können. Beide
Bestandteile der Platte 24 sind mittels den Führungsstiften 27 aneinander lösbar
befestigt, und zwar dadurch, daß in den Stirnseiten der Führungsstifte 27
Gewindebohrungen eingearbeitet sind, in die jeweils eine Senkschraube eindrehbar
ist. Auf diese Weise kann das Gehäuse 12 nahezu vollständig von der Frässcheibe
11 abgenommen werden.In particular, the
Aus den Figuren 4 und 5 ist zu entnehmen, dass an dem Gehäuse 12 des
Handarbeitsgerätes 1 eine Anlageplatte 31 vorgesehen ist, die mittels zweier
Halteschenkel 32 an dem Gehäuse 12 höhenverstellbar arretiert ist. Die Anlageplatte
31 dient als an dem Fensterrahmen 2 anliegendes Führungsglied 23. Mittels der
Höheneinstellung der Anlageplatte 31 kann demnach der Abstand zwischen der
Frässcheibe 11 und dem Fensterrahmen 2 zuverlässig eingestellt werden, ohne
dass die beabsichtigte Führung der Linearbewegung des Handarbeitsgerätes 1
verloren geht.From Figures 4 and 5 it can be seen that on the
Die Halteschenkel 32 sind mittels einer Schraube 33 in jeweils einer Hülse 38
arretiert. Jede der beiden Hülsen 38 weist eine Gewindebohrung 39 auf, durch die
jeweils ein in dem Gehäuse 12 in Lagerbuchsen 37 drehbar gelagerten
Gewindespindel 34 ragt. Die beiden Gewindespindeln 34 sind auf der
gegenüberliegenden Seite der Austrittsöffnung 15 der Frässcheibe 11 formschlüssig
mittels eines Verbindungsstiftes 35 verbunden.
Des weiteren ist in dem Gehäuse 12 eine aus diesem ragende Verstellschraube 36
gelagert, die mit einer der beiden Gewindespindeln 34 formschlüssig
zusammenwirkt. Der Verbindungsstift 35 ist ebenfalls in dem Gehäuse 12 mittels
zweier Lagerbuchsen 37 drehbar gelagert.
Durch Drehen der Verstellschraube 36 rotieren die Gewindespindeln 34, da diese
über Kegelräder mit dem Verbindungsstift 35 in Eingriff stehen, so dass die auf
diesen angeordneten Hülsen 38 synchron bewegt werden. Somit kann auf einfache
Art und Weise der Abstand der Anlageplatte 31 von der Frässcheibe 11 verändert
werden.The holding
