Definitions
- the invention relates to a strip-shaped intermediate layer for fastening to an outer flat glass pane of a stack of flat glass panes according to the preamble of claim 1.
- a fully automatic stacking system as part of a float system uses, among other things.
- Suction cups that can be switched on and off to a vacuum source, in order to capture the flat glass panes in a horizontal position in which they are conveyed, to pivot them and to stack them on a bearing block in an approximately vertical position.
- the suction cups are then switched off so that the suction crossbars to which the suction cups are attached or similar supports can be pivoted back with the glass plate detached.
- strip-shaped intermediate layers are spaced next to one another on an outer flat glass pane of the stack, by means of which this stack is separated from a next stack.
- the stack with the intermediate layers forms a glass package, the size and weight of which is limited by the carrying capacity and conveying capacity of a conveying means.
- the intermediate layers can consist of different materials, such as x • B. Wood, chipboard material, foams or paper honeycombs covered with kraft paper on both sides.
- the intermediate layers have a thickness of 10 to 40 mm, which depends on the intended further transport of the glass packages.
- the length of the strip-shaped intermediate layers is up to approx. 3,200 mm, while the width is dimensioned from 60 to 100 mm.
- Adhesive strips have hitherto been used for fastening the intermediate layers to the outer flat glass pane.
- the intermediate layers are attached directly manually to the outer glass pane using the adhesive strips. This procedure is complex due to the associated personnel costs.
- the glass pane is soiled by the adhesive strips or permanent adhesive particles after the adhesive strips have been removed later. Therefore, the outer pane is e.g. to undergo an intensive and again complex cleaning process to form laminated panes or insulating glass.
- the present invention has for its object to form strip-shaped intermediate layers for attachment to an outer flat glass pane of a stack so that contamination of the flat glass panes by fastening strip-shaped intermediate layers is largely avoided and the laying of the intermediate layers is simplified for the purpose of automation.
- the strip-shaped intermediate layers equipped in this way can be reliably fastened to the outer flat glass pane in a simple manner without any preparatory pulling off of a film and without auxiliary energy for generating a vacuum by simply pressing on.
- the intermediate layers are subsequently removed, no residues remain, in particular no adhesive.
- the flat glass pane can therefore be processed further without extensive cleaning.
- the specified dimensioning of the suction cup in the recess ensures that the strip-shaped intermediate layer, similar to a fastening with adhesive strips, lies tightly against the outer flat glass pane.
- the specified dimensioning also means that the suction cups protrude only slightly from the surfaces which laterally delimit the depression.
- the intermediate layers can thus be stored in a space-saving manner before they are attached.
- a larger number of intermediate layers prepared with the suction cups can furthermore advantageously be stacked one above the other in a magazine in an adapted laying system.
- the strip-shaped intermediate layers prepared with the suction cups can thus be automatically installed over a long period of time without personnel or attached to the flat glass panes by means of the adapted laying device.
- the elastic suction cups consist, for example, of natural or synthetic rubber and are shaped in the basically known manner similar to a hollow cone or a spherical cap, so that they can be pressed on of the suction cup on the flat glass pane, the air is squeezed out of the suction cup and, in the case of the elastic reforming tendency, a vacuum is automatically created in the cavity, as a result of which the adhesion to the flat glass pane is retained.
- suction cups with paper honeycombs glued on both sides with kraft paper is particularly expedient as the material of the intermediate layers, since the kraft paper has a relatively porous or rough surface to which the suction cups do not adhere. Therefore, several can with suction - wells provided strip-shaped intermediate layers of this material above the other in a magazine are stacked. These stacked intermediate layers are therefore only in loose connection with one another, so that they can be easily removed by machine and attached to the flat glass pane.
- the paper honeycombs glued on both sides with kraft paper, which form the intermediate layers, also have the advantage with regard to the attachment of the suction cups that the depressions can be produced by simply pressing them in with the aid of a stamp, the cell walls of the paper honeycomb permanently compressing. In this case, no material-reducing processing is necessary to produce the recess.
- the suction cup can then be fastened in the depression and / or a cell cavity produced in this way by gluing or pressing in a suction cup with a correspondingly shaped lower edge.
- the depressions and the suction cups fastened therein are expediently arranged along a row. At approximately Equidistant distribution of the depressions and suction cups can ensure a uniform adhesive effect over the length of the strip-shaped intermediate layer.
- the intermediate layer has a depression 5, which is produced by pressing in the upper kraft paper and the part of the paper honeycomb located underneath by means of a stamp.
- the area 6 in FIG. 2 indicates how the paper honeycombs are compressed.
- the recess can also be pressed in only centrally in the middle of the strip-shaped intermediate layer, so that the recess has a closed edge which can increase the torsional rigidity of the intermediate layer.
- the intermediate layer only needs to be sufficiently rigid to be attached, since it adheres to the flat glass pane at several points and is no longer subjected to any significant bending stress. Then essentially only pressure loads occur which are reliably absorbed by the sections of the intermediate layers between the recesses.
- An elastic suction cup 7 is mounted centrally in the recess 5.
- the elastic suction cup can be glued on - this is assumed in the drawing - but in other embodiments it can also be connected to the material in the depression by a push-button-like connection.
- the suction cup would have to be formed in its lower region with a circumferential projection, which can form a positive connection with an opening in the kraft paper layer 2.
- the intermediate layer is reliably fastened to the flat glass pane.
- any cracks in the kraft paper and / or the paper honeycombs in the region of the recess 5 can only insignificantly reduce the strength properties of the intermediate layer, so that a strength which is certainly sufficient for the present application is retained. Cracks or destruction of the upper layer of kraft paper and / or the paper honeycomb can be further avoided or reduced by the fact that the depressions are formed with a relatively flat transition to the normal material thickness.

Description
Die Erfindung betrifft eine streifenförmige Zwischenlage zum Befestigen an einer äußeren Flachglasscheibe eines Stapels von Flachglasscheiben nach dem Oberbegriff des Anspruchs 1.The invention relates to a strip-shaped intermediate layer for fastening to an outer flat glass pane of a stack of flat glass panes according to the preamble of
Bei der Herstellung von Flachglas auf einer Floatanlage durchläuft das Floatglas verschiedene Behandlungsstationen, an denen das Glas gemessen, gesichtet, geschnitten, gebrochen und schließlich sortiert und gestapelt wird. Eine solche vollautomatische Stapelanlage als Bestandteil einer Floatanlage verwendet u.a. an eine Vakuumquelle zu- und abschaltbare Sauger, um die Flachglasscheiben in einer horizontalen Lage zu erfassen, in der sie angefördert werden, zu schwenken und an einem Lagerbock in annähernd senkrechte Stellung zu stapeln. Anschließend werden die Sauger abgeschaltet, so daß die Saugtraversen, an denen die Sauger befestigt sind, oder ähnliche Träger bei gelöster Glasplatte zurückgeschwenkt werden können.In the manufacture of flat glass on a float system, the float glass goes through various treatment stations where the glass is measured, sifted, cut, broken and finally sorted and stacked. Such a fully automatic stacking system as part of a float system uses, among other things. Suction cups that can be switched on and off to a vacuum source, in order to capture the flat glass panes in a horizontal position in which they are conveyed, to pivot them and to stack them on a bearing block in an approximately vertical position. The suction cups are then switched off so that the suction crossbars to which the suction cups are attached or similar supports can be pivoted back with the glass plate detached.
Wenn eine vorbestimmte Anzahl Glasscheiben in dieser Weise gestapelt sind, werden an einer äußeren Flachglasscheibe des Stapels im Abstand nebeneinander streifenförmige Zwischenlagen angebracht, durch welche dieses Stapel von einem nächsten Stapel getrennt ist. Das Stapel mit den Zwischenlagen bildet ein Glaspaket, dessen Größe und Gewicht durch die Tragkraft und Förderkapazität eines Fördermittels begrenzt ist.If a predetermined number of glass panes are stacked in this way, strip-shaped intermediate layers are spaced next to one another on an outer flat glass pane of the stack, by means of which this stack is separated from a next stack. The stack with the intermediate layers forms a glass package, the size and weight of which is limited by the carrying capacity and conveying capacity of a conveying means.
Im einzelnen werden auf einer äußeren Flachglasscheibe in der Regel 6 bis 7 streifenförmige Zwischenlagen parallel im Abstand zueinander befestigt. Die Zwischenlagen können nach dem Stand der Technik aus verschiedenen Werkstoffen bestehen, wie x•B. Holz, Spanplattenmaterial, Schaumstoffen oder beidseitig mit Kraftpapier beklebten Papierwaben. Die Zwischenlagen haben eine Stärke von 10 bis 40 mm, die sich nach der beabsichtigten weiteren Beförderung der Glaspakete richtet. Die Länge der streifenförmigen Zwischenlagen beträgt bis ca. 3.200 mm, während die Breite auf 60 bis 100 mm bemessen ist.Specifically, 6 to 7 strip-shaped intermediate layers are fastened in parallel at a distance from one another on an outer flat glass pane. According to the prior art, the intermediate layers can consist of different materials, such as x • B. Wood, chipboard material, foams or paper honeycombs covered with kraft paper on both sides. The intermediate layers have a thickness of 10 to 40 mm, which depends on the intended further transport of the glass packages. The length of the strip-shaped intermediate layers is up to approx. 3,200 mm, while the width is dimensioned from 60 to 100 mm.
Zur Befestigung der Zwischenlagen an der äußeren Flachglasscheibe sind bisher Klebestreifen verwendet worden. Nach einem herkömmlichen Verfahren werden die Zwischenlagen unmittelbar manuell mittels der Klebestreifen an der äußeren Glasscheibe angebracht. Dieses Verfahren ist aufgrund der damit verbundenen Personalkosten aufwendig. Außerdem wird die Glasscheibe durch die Klebstoffstreifen bzw. haften bleibende Klebstoffteilchen nach einer späteren Entfernung der Klebstoffstreifen verschmutzt. Daher ist die äußere Scheibe vor einer weiteren Verarbeitung z.B. zu Verbundscheiben oder Isolierglas einem intensiven und wiederum aufwendigen Reinigungsvorgang zu unterziehen.Adhesive strips have hitherto been used for fastening the intermediate layers to the outer flat glass pane. According to a conventional method, the intermediate layers are attached directly manually to the outer glass pane using the adhesive strips. This procedure is complex due to the associated personnel costs. In addition, the glass pane is soiled by the adhesive strips or permanent adhesive particles after the adhesive strips have been removed later. Therefore, the outer pane is e.g. to undergo an intensive and again complex cleaning process to form laminated panes or insulating glass.
Die voranstehend genannten Nachteile können nur teilweise durch eine Teilautomatisierung nach einem ebenfalls bekannten Verfahren vermieden werden, das von einer Verlegevorrichtung für die Zwischenlagen Gebrauch macht. Diese zum Stand der Technik gehörenden Verlegevorrichtungen sind so eingerichtet, daß sie nur immer eine einzige Zwischenlage aufnehmen und mittels eines doppelseitig klebenden Klebestreifens an der äußeren Flachglasscheibe anbringen können. Es ist also auch hier Personal notwendig, welches vor dem Einlegen der jeweiligen Zwischenlage in die Verlegvorrichtung eine Schutzfolie von dem Klebestreifen entfernen muß, welcher mit einer klebenden Seite an der Zwischenlage angebracht war. Es lassen sich so zwar viele Zwischenlagen vorbereiten und auf Lager halten, jedoch ist eine automatische Anbringung einer Reihe von Zwischenlagen ohne Hilfspersonal nicht ohne weiteres möglich.The above-mentioned disadvantages can only be partially avoided by partial automation according to a likewise known method which makes use of a laying device for the intermediate layers. These laying devices belonging to the state of the art are set up in such a way that they can only ever take up a single intermediate layer and attach them to the outer flat glass pane by means of a double-sided adhesive strip. It is therefore also necessary here for personnel who, before inserting the respective intermediate layer into the laying device, must remove a protective film from the adhesive strip which was attached to the intermediate layer with an adhesive side. Many intermediate layers can be prepared and kept in stock in this way, however, automatic attachment of a number of intermediate layers without auxiliary personnel is not readily possible.
Es ist zwar schon bekannt, Schutz- und Unterlagsklötze zum Anbringen an Glasscheiben mit einem Sauger oder Saugnapf zu verbinden, der parallel zur Glasfläche liegend an dieser haften kann (DE-GM 19 42 869). Damit soll das bisher notwendige langwierige Befestigen des Schutz- und Unterlagsklotzes mittels einer Schnur oder eines Seiles entfallen. Damit ist aber dem Fachmann nicht die Lehre bekannt, ob und gegebenenfalls wie im einzelnen Saugnäpfe an streifenförmigen Zwischenlagen eingesetzt werden können, um die geschilderten Nachteile der bisherigen Zwischenlagenbefestigungen zu überwinden.It is already known to connect protective and support blocks for attachment to glass panes with a suction cup or suction cup, which can adhere to the glass surface lying parallel to it (DE-GM 19 42 869). This is intended to eliminate the lengthy fastening of the protective and supporting block, which was previously necessary, by means of a cord or a rope. However, the person skilled in the art is not aware of the teaching as to whether and, if necessary, how individual suction cups can be used on strip-shaped intermediate layers in order to overcome the disadvantages of the previous intermediate layer fastenings described.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, streifenförmige Zwischenlagen zum Befestigen an einer äußeren Flachglasscheibe eines Stapels so auszubilden, daß eine Verschmutzung der Flachglasscheiben durch Befestigung streifenförmiger Zwischenlagen weitgehendst vermieden und die Verlegung der Zwischenlagen zum Zwecke der Automatisierung vereinfacht wird.The present invention has for its object to form strip-shaped intermediate layers for attachment to an outer flat glass pane of a stack so that contamination of the flat glass panes by fastening strip-shaped intermediate layers is largely avoided and the laying of the intermediate layers is simplified for the purpose of automation.
Diese Aufgabe wird durch die in dem kennzeichnenden Teil des Anspruchs 1 angegebene Erfindung gelöst.This object is achieved by the invention specified in the characterizing part of
Die derart ausgestatteten streifenförmigen Zwischenlagen können selbsttätig in einfacher Weise ohne vorbereitendes Abziehen einer Folie und ohne Hilfsenergie zu einer Vakuumerzeugung an der jeweils äußeren Flachglasscheibe zuverlässig durch einfaches Andrücken befestigt werden. Bei der späteren Entfernung der Zwischenlagen bleiben keine Rückstände, insbesondere kein Klebstoff zurück. Die Flachglasscheibe kann daher ohne aufwendige Reinigung weiterverarbeitet werden. Durch die angegebene Dimensionierung des Saugnapfes in der Vertiefung wird erreicht, daß die streifenförmige Zwischenlage, ähnlich wie bei einer Befestigung mit Klebestreifen, dicht an der äußeren Flachglasscheibe anliegt.The strip-shaped intermediate layers equipped in this way can be reliably fastened to the outer flat glass pane in a simple manner without any preparatory pulling off of a film and without auxiliary energy for generating a vacuum by simply pressing on. When the intermediate layers are subsequently removed, no residues remain, in particular no adhesive. The flat glass pane can therefore be processed further without extensive cleaning. The specified dimensioning of the suction cup in the recess ensures that the strip-shaped intermediate layer, similar to a fastening with adhesive strips, lies tightly against the outer flat glass pane.
Die angegebene Dimensionierung beinhaitet auch, daß die Saugnäpfe nur wenig über die die Vertiefung seitlich begrenzenden Oberflächen hervorstehen. Damit können die Zwischenlagen vor ihrer Anbringung raumsparend gelagert werden.The specified dimensioning also means that the suction cups protrude only slightly from the surfaces which laterally delimit the depression. The intermediate layers can thus be stored in a space-saving manner before they are attached.
Bei der Verwendung von porigem Material für die streifenförmigen Zwischenlagen läßt sich weiter in vorteilhafter Weise eine größere Anzahl von mit den Saugnäpfen vorbereiteten Zwischenlagen übereinander in einem Magazin in einer angepaßten Verlegeanlage stapeln. Damit können die mit den Saugnäpfen vorbereiteten streifenförmigen Zwischenlagen mittels der angepaßten Verlegevorrichtung über einen langen Zeitraum automatisch ohne Personal verlegt bzw. an die Flachglasscheiben angebracht werden.When using porous material for the strip-shaped intermediate layers, a larger number of intermediate layers prepared with the suction cups can furthermore advantageously be stacked one above the other in a magazine in an adapted laying system. The strip-shaped intermediate layers prepared with the suction cups can thus be automatically installed over a long period of time without personnel or attached to the flat glass panes by means of the adapted laying device.
Die elastischen Saugnäpfe bestehen beispielsweise aus natürlichem oder synthetischem Gummi und sind in der grundsätzlich bekannten Weise ähnlich einem Hohlkonus oder einer Kugelkalotte geformt, so daß durch Anpressen des Saugnapfes an die Flachglasscheibe die Luft aus dem Saugnapf ausgedrückt wird und bei der eleastischen Rückformtendenz ein Vakuum in dem Hohlraum selbsttätig entsteht, wodurch die Haftung an der Flachglasscheibe erhalten bleibt. Dabei wird ausgenutzt, daß die Flachglasscheibe eine plane, praktisch porenfreie Oberfläche aufweist.The elastic suction cups consist, for example, of natural or synthetic rubber and are shaped in the basically known manner similar to a hollow cone or a spherical cap, so that they can be pressed on of the suction cup on the flat glass pane, the air is squeezed out of the suction cup and, in the case of the elastic reforming tendency, a vacuum is automatically created in the cavity, as a result of which the adhesion to the flat glass pane is retained. This takes advantage of the fact that the flat glass pane has a flat, practically non-porous surface.
Besonders zweckmäßig ist die Kombination der Saugnäpfe mit beidseitig mit Kraftpapier beklebten Papierwaben als Material der Zwischenlagen, da das Kraftpapier eine verhältnismäßig porige bzw. rauhe Oberfläche hat, an der die Saugnäpfe nicht anhaften. Daher können mehrere mit Saug- näpfen versehene streifenförmige Zwischenlagen aus diesem Material übereinander in einem Magazin gestapelt werden. Diese gestapelten Zwischenlagen stehen also miteinander nur in loser Verbindung, so daß sie maschinell leicht entnommen und an der Flachglasscheibe angebracht werden können.The combination of the suction cups with paper honeycombs glued on both sides with kraft paper is particularly expedient as the material of the intermediate layers, since the kraft paper has a relatively porous or rough surface to which the suction cups do not adhere. Therefore, several can with suction - wells provided strip-shaped intermediate layers of this material above the other in a magazine are stacked. These stacked intermediate layers are therefore only in loose connection with one another, so that they can be easily removed by machine and attached to the flat glass pane.
Die beidseitig mit Kraftpapier beklebten Papierwaben, die die Zwischenlagen bilden, haben im Hinblick auf die Anbringung der Saugnäpfe auch den Vorteil, daß die Vertiefungen durch einfaches Eindrücken mit Hilfe eines Stempels erzeugt werden können, wobei die Zellwände der Papierwabe sich bleibend zusammenstauchen. Zur Herstellung der Vertiefung ist also in diesem Fall keine Material-abnehmende Bearbeitung notwendig. Die Befestigung des Saugnapfes in der damit erzeugten Vertiefung und/oder einem Zellenhohlraum kann dann durch Kleben oder Eindrücken eines Saugnapfes mit einem entsprechend geformten unteren Rand erfolgen.The paper honeycombs glued on both sides with kraft paper, which form the intermediate layers, also have the advantage with regard to the attachment of the suction cups that the depressions can be produced by simply pressing them in with the aid of a stamp, the cell walls of the paper honeycomb permanently compressing. In this case, no material-reducing processing is necessary to produce the recess. The suction cup can then be fastened in the depression and / or a cell cavity produced in this way by gluing or pressing in a suction cup with a correspondingly shaped lower edge.
Zweckmäßig sind die Vertiefungen und die darin befestigten Saugnäpfe längs einer Reihe angeordnet. Bei annähernd äquidistanter Verteilung der Vertiefungen und Saugnägfe kann für eine gleichmäßige Haftwirkung über die Länge der streifenförmigen Zwischenlage gesorgt werden.The depressions and the suction cups fastened therein are expediently arranged along a row. At approximately Equidistant distribution of the depressions and suction cups can ensure a uniform adhesive effect over the length of the strip-shaped intermediate layer.
Ein Ausführungsbeispiel der erfindungsgemäßen streifenförmigen Zwischenlage wird im folgenden anhand einer Zeichnung mit zwei Figuren erläutert. Es zeigt:
- Fig. 1 eine mit einem Saugnapf versehene Zwischenlage in einer schaubildlichen Ansicht von oben und
- Fig. 2 die Zwischenlage nach Fig. 1 in einer Seitenansicht.
- In Fig. 1 ist ein Abschnitt einer streifenförmigen Zwischenlage mit 1 bezeichnet. Die Zwischenlage besteht aus beidseitig mit
Kraftpapier 2, 3 beklebten Papierwaben 4.
- Fig. 1 is a liner provided with a suction cup in a perspective view from above and
- Fig. 2 shows the intermediate layer of FIG. 1 in a side view.
- In Fig. 1, a section of a strip-shaped intermediate layer is designated by 1. The intermediate layer consists of paper honeycombs 4 stuck on both sides with
kraft paper 2, 3.
Die Zwischenlage weist eine Vertiefung 5 auf, die durch Eindrücken des oberen Kraftpapiers und des darunter befindlichen Teils der Papierwaben mittels eines Stempels hergestellt ist. In dem Bereich 6 ist in Fig. 2 angedeutet, wie die Papierwaben zusammengestaucht sind. - Anstelle der in den Fig. 1 und 2 dargestellten, über die Breite durchgehenden Vertiefung, kann die Vertiefung auch nur zentral in der Mitte der streifenförmigen Zwischenlage eingedrückt sein, so daß die Vertiefung einen geschlossenen Rand aufweist, der die Verwindungssteifigkeit der Zwischenlage erböben kann. Andererseits braucht die Zwischenlage nur zur Anbringung genügend biegesteif zu sein, da sie an der Flachglasscheibe an mehreren Stellen anhaftend keiner nennenswerten Biegebeanspruchung mehr unterworfen wird. Es treten dann im wesentlichen nur Druckbelastungen auf, die durch die Partien der Zwischenlagen zwischen den Ausspartungen sicher aufgenommen werden.The intermediate layer has a
Zentral ist in der Vertiefung 5 jeweils ein elastischer Saugnapf 7 angebracht. Der elastische Saugnapf kann angeklebt sein - dies ist in der Zeichnung angenommen - aber in anderen Ausführungsformen auch durch eine druckknopf- ähnliche Verbindung mit dem Material in der Vertiefung verbunden sein. Hierzu wäre der Saugnapf in seinem unteren Bereich mit einem umlaufenden Vorsprung auszubilden, der mit einer Durchbrechung der Kraftpapierschicht 2 eine formschlüssige Verbindung eingehen kann.An
Anstelle eines einzigen in jeder Vertiefung vorgesehenen Saugnapfes ist es auch möglich, zwei oder mehrere kleinere Saugnäpfe vorzusehen, die eine größere Sicherheit bei Funktionslosigkeit eines Saugnapfes, beispielsweise infolge einer nicht erkannten Beschädigung, haben.Instead of a single suction cup provided in each recess, it is also possible to provide two or more smaller suction cups which have greater security when a suction cup is inoperative, for example as a result of undetected damage.
Eine bevorzugte Dimensionierung des Saugnapfes ist in Bezug auf die Vertiefung in Fig. 2 dargestellt:
- Die Vertiefung hat eine Tiefe V, die einen Bruchteil der Höhe bzw. Stärke H der Zwischenlage beträgt. Die Zwischenlage soll wesentlich stärker als die Absenkung der Vertiefung sein, damit genügende Festigkeitseigenschaften auch im Bereich der Vertiefung gegeben sind. Der Saugnapf ist so bemessen, daß er im entspannten Zustand, d.h. wenn er nicht an eine Flachglasscheibe angedrückt ist, eine Höhe S hat, die etwas größer als die Tiefe V der Vertiefung ist. Damit kann die obere offene Seite des Saugnapfes mit Sicherheit zur Anlage an die Flachglasscheibe gelangen und unter Andruck an die Flachglasscheibe so verformt werden, daß der Saugnapf völlig in die Vertiefung zurückweicht. Dies heißt, daß die Oberfläche des
Kraftpapiers 2 und ein oberer nicht bezeichneter Rand des Saugnapfes in einer
- The depression has a depth V which is a fraction of the height or thickness H of the intermediate layer. The intermediate layer should be much stronger than the depression of the depression, so that sufficient strength properties are also provided in the area of the depression. The suction cup is dimensioned such that in the relaxed state, ie when it is not pressed against a flat glass pane, it has a height S which is somewhat greater than the depth V of the depression. Thus, the upper open side of the suction cup can safely come into contact with the flat glass pane and be deformed under pressure on the flat glass pane so that the suction cup completely withdraws into the recess. This means that the surface of the
kraft paper 2 and an upper unspecified edge of the suction cup in one
Durch eine nicht dargestellte Anordnung einer Vielzahl von Vertiefungen und Saugnäpfen in einer Reihe längs einer gedachten Mittellinie der streifenförmigen Zwischenlage wird die Zwischenlage zuverlässig an der Flachglasscheibe befestigt.By arranging a plurality of depressions and suction cups (not shown) in a row along an imaginary center line of the strip-shaped intermediate layer, the intermediate layer is reliably fastened to the flat glass pane.
Bei dem Entfernen der streifenförmigen Zwischenlage mit den Saugnäpfen hinterlassen diese auf der Flachglasscheibe praktisch keine Rückstände. Aus diesem Grund braucht die Flachglasscheibe vor der weiteren Verarbeitung nicht gesondert gereinigt zu werden.When removing the strip-shaped intermediate layer with the suction cups, these leave practically no residue on the flat glass pane. For this reason, the flat glass pane does not need to be cleaned separately before further processing.
Es wird noch bemerkt, daß durch etwaige Risse in dem Kraftpapier und/oder den Papierwaben im Bereich der Vertiefung 5 die Festigkeitseigenschaften der Zwischenlage nur unwesentlich vermindert sein können, so daß eine für den vorliegenden Anwendungsfall sicher ausreichende Festigkeit erhalten bleibt. Risse bzw. Zerstörungen der oberen Kraftpapierlage und/oder der Papierwaben können weiter dadurch vermieden oder herabgesetzt werden, daß die Vertiefungen mit einem verhältnismäßig flachen Übergang zu der normalen Materialstärke ausgebildet sind.It is also noted that any cracks in the kraft paper and / or the paper honeycombs in the region of the
