Abstract

The invention relates to a method for producing a strip-shaped object (48) of any thickness, width and length, made up of stacked, partially glued together foil strips (30). According to said method, each of the foil strips (30) is provided with adhesive strips (18) applied across the width (u) of the foil strip on one side, and the adhesive strips (18) are offset from each other on foil strips (30) that directly follow each other. The foil strips (30) are stacked to produce a foil strip stack (39), pressed against each other in the stacking direction and glued together in order to produce the strip-shaped object (48). In the process, a line of foil (22) which is provided with adhesive strips (18) crosswise to its longitudinal direction (x) is divided into at least two lines of foil strips (29) of equal width in its longitudinal direction (u). The individual lines (29) of foil strips are deviated and guided one above the other with adhesive strips (18) which are offset from each other, cut into sections from foil strip packets (34) consisting of individual foil strips (30), in cycles, and fed to the foil strip stack (39) in the form of foil strip packets (34).

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines aus gestapelten und partiell miteinander verklebten Folienstreifen gebildeten bandförmigen Gegenstandes nach dem Oberbegriff von Anspruch 1 und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing a band-shaped article formed from stacked and partially glued together foil strips according to the preamble of claim 1 and an apparatus for performing the method.

Zur Herstellung eines bandförmigen Gegenstandes aus partiell miteinander verklebten Folienstreifen sind heute grundsätzlich zwei Verfahren bekannt. Ein erstes Verfahren betrifft die Herstellung von Blöcken aus aufeinander gelegten, mit Klebstoffstreifen versehenen Folienblättem mit nachfolgendem Verkleben der einzelnen Blätter untereinander unter Einwirkung von Druck und Temperatur, wobei die derart hergestellten Blöcke zu Scheiben zersägt werden, deren Schnittbreite der späteren Dicke des bandförmigen Gegenstandes entspricht. Durch Zusammenkleben der einzelnen Scheiben ergibt sich ein quasi endloser Gegenstand. Diese Herstellungsweise ist beispielsweise in der DE-A-2342076 offenbart und wird heute in der Praxis angewendet.To produce a band-shaped article from partially glued together foil strips today two methods are generally known. A first method relates to the production of blocks of superimposed, provided with adhesive strips foil sheets with subsequent adhesion of the individual sheets under pressure and temperature, wherein the blocks thus produced are sawn into slices whose cutting width corresponds to the later thickness of the band-shaped object. By gluing together the individual slices results in a quasi-endless object. This method of preparation is disclosed, for example, in DE-A-2342076 and is now practiced.

Der Nachteil dieser vorbekannten Herstellung über eine Blockfertigung mit anschliessendem Zersägen der Blöcke zu einzelnen Scheiben liegt vor allem darin, dass bei wirtschaftlicher Herstellung die Blöcke so dick sind, dass die Wärmezufuhr in den Block zur Auslösung des Verklebungsprozesses lange Heiz- und Presszeiten erfordert und darüber hinaus zu einer ungleichmässigen Temperaturverteilung mit entsprechender Qualitätsminderung am Endprodukt führen kann. Das anschliessende Zerschneiden eines Blockes mittels einer Bandsäge zu Scheiben führt zu einem beträchtlichen Abfall. Zudem sind zur Herstellung des aus partiell miteinander verklebten Folienstreifen gebildeten bandförmigen Gegenstandes vier einzelne Verarbeitungsschritte erforderlich, nämlich

  1. 1. Stapeln der mit Klebstoffstreifen versehenen Blätter
  2. 2. Pressen der gestapelten Blätter zu einem Block
  3. 3. Zersägen des Blockes in einzelne Scheiben und
  4. 4. Verkleben der einzelnen Scheiben zum quasi endlosen Gegenstand.
The disadvantage of this prior art production via a block production with subsequent sawing of the blocks to individual slices is above all that in economic production, the blocks are so thick that the heat input into the block to trigger the bonding process requires long heating and pressing times and beyond can lead to a non-uniform temperature distribution with a corresponding reduction in quality of the final product. The subsequent cutting of a block by means of a band saw to discs leads to a considerable drop. In addition, for the production of partially bonded together film strips band-shaped object four individual processing steps required, namely
  1. 1. Stack the sheets provided with adhesive strips
  2. 2. Press the stacked sheets into a block
  3. 3. sawing the block into individual slices and
  4. 4. Gluing the individual discs to the quasi-endless object.

Hinzu kommt, dass die Verklebung der einzelnen Scheiben Stellen im Gegenstand ergibt, welche die Eigenschaften des Gegenstandes ungünstig beeinflussen und deshalb unter Umständen sogar entfernt werden müssen.In addition, the bonding of the individual discs results in places in the object, which adversely affect the properties of the object and therefore may even have to be removed.

Die zweite Herstellungsart geht aus von mit Klebstoffstreifen versehenen Folienstreifen, die übereinander gestapelt und unter Druck in Stapelrichtung und unter Wärmezufuhr zu einem endlosen bandförmigen Gegenstand gepresst werden. Ein derartiges Verfahren ist beispielsweise aus der DE-C-3820718 bekannt. Dort wird eine Folienbahn kontinuierlich mit längslaufenden Klebstoffstreifen versehen. Die einzelnen Folienstreifen werden quer zur Laufrichtung der Folienbahn in Linie geschnitten, übereinander zu einem Folienstreifenstapel gestapelt und unter Druck in Stapelrichtung und unter Wärmezufuhr zu dem endlosen bandförmigen Gegenstand gepresst.The second type of production is based on strip of adhesive film, which are stacked and pressed under pressure in the stacking direction and under heat to an endless belt-shaped object. Such a method is known for example from DE-C-3820718. There, a film web is continuously provided with longitudinal adhesive strips. The individual film strips are cut transversely to the running direction of the film web in line, stacked one above the other to form a film strip stack and pressed under pressure in the stacking direction and under heat to the endless belt-shaped object.

Der wesentliche Nachteil dieses Verfahrens liegt vor allem in der niedrigen Produktionsgeschwindigkeit, die selbst bei gleichzeitigem Zusammenführen von zwei Folienbahnen zum Schneiden der einzelnen Folienstreifen für eine wirtschaftliche Herstellung eines endlosen bandförmigen Gegenstandes nicht entscheidend erhöht werden kann. Trotz der Vorteile, die sich gegenüber der herkömmlichen Blockherstellung hinsichtlich der verbesserten Wärmeeintragung zur Verklebung des Folienstreifenstapels sowie des stark verminderten Besäumungabfalls beim Zuschneiden der einzelnen Folienstreifen ergeben, konnten sich die auf diesem Prinzip beruhenden Verfahren in der Praxis bislang nicht durchsetzen.The main disadvantage of this method is mainly in the low production speed, which can not be significantly increased even with simultaneous merging of two film webs for cutting the individual film strips for economical production of an endless band-shaped object. Despite the advantages compared to the conventional block production in terms of improved heat input for bonding the film strip stack and the greatly reduced Besäumungabfalls when cutting the individual film strips, So far, the procedures based on this principle have not been successful in practice.

Ein Verfahren der eingangs genannten Art und eine zur Durchführung des Verfahrensgeeignete Vorrichtunng sind aus DE-A 26 05 224 und US-A-3 741 840 bekannt.A method of the type mentioned above and a Vorrichtunng suitable for carrying out the method are known from DE-A 26 05 224 and US-A-3 741 840.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, mit welchem ein aus partiell miteinander verklebten Folienstreifen gebildeter bandförmiger Gegenstand von hoher Qualität wirtschaftlich in einer Linie hergestellt werden kann. Ein weiteres Ziel ist die Schaffung einer zur Durchführung des Verfahrens geeigneten Vorrichtung.The invention has for its object to provide a method of the type mentioned, with which a formed from partially glued together foil strip band-shaped object of high quality can be produced economically in a line. Another object is to provide a device suitable for carrying out the method.

Zur erfindungsgemässen Lösung der Aufgabe, dass eine quer zu ihrer Längsrichtung mit Klebstoffstreifen versehene Folienbahn in ihrer Längsrichtung in wenigstens zwei Folienstreifenbahnen gleicher Breite aufgeteilt wird und die einzelnen Folienstreifenbahnen umgelenkt und mit versetzt zueinander stehenden Klebstoffstreifen übereinander geführt, taktweise als aus einzelnen Folienstreifen bestehende Folienstreifenpakete abgelängt und als Folienstreifenpakete dem Folienstreifenstapel zugeführt werden.To the inventive solution of the problem that a transversely to its longitudinal direction provided with strips of adhesive film web is divided in its longitudinal direction in at least two film strip webs of equal width and deflected the individual film strip webs and staggered with each other adhesive strips on top of each other, intermittently cut as consisting of individual film strips film strip packages and be supplied as foil strip packages the film strip stack.

Ein bevorzugtes Material für die Folien besteht aus Aluminium oder aus einer Aluminiumlegierung. Je nach Verwendungszweck des bandförmigen Gegenstandes können aber auch andere Werkstoffe als Folienmaterial eingesetzt werden, beispielsweise Papier, Kunststoffe, andere Metallfolien oder auch Laminate aus den genannten Materialien.A preferred material for the films is aluminum or an aluminum alloy. Depending on the intended use of the band-shaped article but other materials can be used as a film material, such as paper, plastics, other metal foils or laminates of the materials mentioned.

Während des Verklebungsvorganges können die Folienstreifen im Folienstreifenstapel erwärmt und/oder gekühlt werden.During the bonding process, the film strips in the film strip stack can be heated and / or cooled.

Die Aufteilung der Folienbahn in die einzelnen Folienstreifenbahnen erfolgt bevorzugt durch abfallfreies Schneiden.The distribution of the film web in the individual film strip webs is preferably carried out by waste-free cutting.

Anstelle der Verwendung einer vorgefertigten Folienbahn kann diese auch in Linie vorbehandelt und mit den Klebstoffstreifen versehen werden.Instead of using a prefabricated film web, this can also be pretreated in line and provided with the adhesive strip.

Bevorzugt weist die erste Schneidstation zum Aufteilen der Folienbahn in die einzelnen Folienstreifenbahnen eine Schneideinrichtung zum abfallfreien Schneiden auf. Dadurch kann die Folienbahn in Folienstreifenbahnen beliebiger und genauer Breite aufgeteilt werden.The first cutting station preferably has a cutting device for waste-free cutting for dividing the film web into the individual film strip webs. As a result, the film web can be divided into film strip webs of any desired and exact width.

Die Umlenkstation zum Umlenken und Übereinanderführen der einzelnen Folienstreifenbahnen weist bevorzugt in einem Winkel von 45° zur Folienbahn angeordnete Rollen auf.The deflection station for deflecting and superimposing the individual film strip webs preferably has rollers arranged at an angle of 45 ° to the film web.

Der Umlenkvorgang kann beispielsweise über Rollen erfolgen, die in einem Winkel von 45° zur Folienbahn angeordnet sind.The individual film strip webs 29 are subsequently deflected in a deflection station 32 and positioned one above the other so that the adhesive strips 18 immediately adjacent film strip webs 29 are offset by half a distance a of the adhesive strip 18 against each other. The deflection can be done for example via rollers which are arranged at an angle of 45 ° to the film web.

Die aus der Umlenkstation 32 austretenden Folienstreifenbahnen 29 mit gegeneinander versetzt angeordneten Klebstoffstreifen 18 werden in einer zweiten Transportrichtung y nach dem Ablängen mittels eines mitlaufenden Schneidmessers 36 auf die gewünschte Länge I als aus einzelnen Folienstreifen 30 bestehende Folienstreifenpakete 34 auf ein Einschubelement 38 gelegt. Das Einschubelement 38 mit dem aufliegenden Folienstreifenpaket 34 bewegt sich anschliessend in einen Spalt 62 einer Stapelmoduls 60.The film strips 29 emerging from the deflection station 32 with mutually staggered adhesive strips 18 are laid on a plug-in element 38 in a second transport direction y after cutting to length by means of a follower cutting blade 36 to the desired length I as film strips consisting of individual film strips 30. The insertion element 38 with the foil strip package 34 lying on it then moves into a gap 62 of a stacking module 60.

Je nach gewünschter Länge L des herzustellenden bandförmigen Gegenstandes oder Bandabschnittes kann ein Stapelmodul 60 mit entsprechend angepasster Länge und Breite eingesetzt werden.Depending on the desired length L of the band-shaped article or band section to be produced, a stacking module 60 with a suitably adapted length and width can be used.

Sobald der Folienstreifenstapel 39 im Stapelmodul 60 die gewünschte Länge L erreicht hat, wird das Stapelmodul 60 mit dem Folienstreifenstapel 39 aus der Anordnung entfernt und durch ein gleiches oder unterschiedliches Stapelmodul 60 ausgetauscht.As soon as the film strip stack 39 in the stacking module 60 has reached the desired length L, the stacking module 60 with the film strip stack 39 is removed from the arrangement and replaced by an identical or different stacking module 60.

In den Spalt 62 des mit dem Folienstreifenstapel 39 beladenen Stapelmoduls 60 werden beidseitig Begrenzungselemente 64 eingeführt und zur Einstellung eines zur Verklebung der Folienstreifen 30 ausreichenden Anpressdruckes p gegen den Folienstreifenstapel 39 gedrückt. Bei Bedarf kann dem Stapelmodul 60 anschliessend direkt oder indirekt - z.B. in einem Ofen - die zur Verklebung der Folienstreifen benötigte Wärme zugeführt werden. Gegebenenfalls kann das Stapelmodul 60 auch abgekühlt werden.In the gap 62 of loaded with the foil strip stack 39 stacking module 60 on both sides limiting elements 64 are introduced and pressed to set a sufficient for bonding the film strip 30 contact pressure p against the film strip stack 39. If desired, the stacking module 60 can then be directly or indirectly - e.g. in an oven - the heat needed to glue the film strips. Optionally, the stacking module 60 may also be cooled.

Nach erfolgter Verklebung wird der Folienstreifenstapel 39 dem Stapelmodul 60 als bandförmiger Gegenstand 48 einer Länge L und einer Breite B entnommen.After bonding, the foil strip stack 39 is removed from the stack module 60 as a band-shaped article 48 of a length L and a width B.

Die gezeigte Anordnung eignet sich insbesondere für die Herstellung kleiner Serien bandförmiger Gegenstände 48 mit häufig wechselnden Dimensionen sowie für Einzelanfertigungen.The arrangement shown is particularly suitable for the production of small series band-shaped objects 48 with frequently changing dimensions and for custom-made.

Mit dem beschriebenen Verfahren können eine Vielzahl von Werkstoffen zu einem aus partiell miteinander verklebten Folienstreifen gebildeten bandförmigen Gegenstand 48 verarbeitet werden, beispielsweise Papier, Kunststoffe, Metallfolien wie zB. Aluminiumfolien oder auch Laminate aus den genannten Materialien. Der beschriebene bandförmige Gegenstand kann z.B. in gestrecktem Zustand allein oder im Verbund mit einer oder zwei Deckschichten oder -blechen als Leichtbaumaterial in vielen Anwendungsbereichen eingesetzt werden.With the described method, a multiplicity of materials can be processed to form a band-shaped article 48, which is formed from partially adhered film strips, for example paper, plastics, metal foils, such as, for example. Aluminum foils or laminates of the materials mentioned. The described band-shaped article may e.g. be used in the stretched state alone or in combination with one or two cover layers or sheets as lightweight material in many applications.
