Abstract

Embossing process for making decorative seams in deep-drawn sheet material, is effected directly after the deep drawing with the sheet material, still in the deep drawing mould.

Description

V.rfahr.n und Vorrichtung zu. Prägen von Verzierungen in tiefgezogene Folien Die Erfindung bezieht sich auf ein Verfahren und auf eine Vorrichtung zum Prägen von Verzierungen, z.B. Ziernähten, in mit einer Vakuum-Tiefziehanlage tiefgezogene Folien o.dgl. V. rfahr.n and device to. Embossing of decorations in deep-drawn Films The invention relates to a method and an apparatus for Embossing of decorations, e.g. decorative seams, in deep-drawn with a vacuum deep-drawing machine Foils or the like.

Seither wird das Anbringen von geprägten Verzierungen auf Folien, Platten o dgl. entweder vor den Tiefziehen oder nach den Tiefziehen vorgenommen. In der Praxis hat di.s den Nachteil, daß bein Herstellen der Prägung vor dem Tiefziehen große Erfahrung erforderlich ist, die Prägung an die richtige Stelle zu setzen, und daß in gleicher Weise wie bei eine. Prägen nach den Tiefziehen eine zusätzliche Erwär-ing der Folie erforderlich ist.Since then, the application of embossed decorations on foils, Plates or the like. Made either before the deep drawing or after the deep drawing. In practice, di.s has the disadvantage that when producing the embossing before deep drawing great experience is required to put the imprint in the right place, and that in the same way as with a. Embossing an additional one after deep drawing Warming of the slide is required.

Der Erfindung liegt die Aufgabe zugrunde1 die geschilderten Nachteile zu vermeiden.The invention is based on the described disadvantages to avoid.

Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß das Prägen unmittelbar im Anschluß an den Tiefziehvorgang unter Belassung der Folie o.dgl. in der Ziehform der Tiefziehanlage stattfindet Durch die Erfindung wird ein besonderer Arbeitsgang eingespart. Es ist keine zusätzliche Erwärmung der Folia o.dgl. erforderlich, weil die Wärme der Folie o.dgl. vom Tiefzehvorgang ausgenutzt wird Außerdem gelingt es, die vorgesehene Prägung immer genau an die richtige Stelle zu sezten.According to the invention, the object is achieved in that the Embossing immediately after the deep-drawing process, leaving the film in place or the like. takes place in the drawing form of the deep-drawing system special work step saved. It is no additional warming the Folia or the like. required because the heat of the film or the like. from the deep toe process is also used, it is always possible to exactly match the intended embossing to set the right place.

In Ausgestaltung des Erfindungsgedankes kann bei einer positiven Ziebforn für die Folie o.dgl. ein mit einem Prägewerkzeug verßehener Oberstempel vorgesehen deine Ferner kann in der Ziehform in Bereich der stattfindend'en Prägung eine elastische Einlage angeordnet sein.In an embodiment of the inventive concept, in the case of a positive Ziebformn for the foil or the like. an upper punch provided with an embossing tool Furthermore, in the drawing form in the area of the embossing that takes place, an elastic Be arranged insert.

Bei einer negativen Ziehform für die Folie o.dgl. kann das Prägewerkzeug in der Ziehform sugeordnet sein und ein gegebenenfalls mit einer elastischen Zwischenlage versehener Oberstempel kann vorgesehen sein, der den Prägedruck aufbringt.With a negative drawing form for the film or the like. can the embossing tool be ordered in the drawing form and optionally with an elastic intermediate layer provided upper punch can be provided which applies the embossing pressure.

In der Zeichnung ist der Gegenstand der Erfindung in zwei Ausftihrungsbeispielen schematisch dargestellt. Es zeigen: Fig. 1 eine positive Ziehform und Fig 2 eine negative Ziehform.In the drawing, the subject matter of the invention is shown in two exemplary embodiments shown schematically. The figures show: FIG. 1 a positive drawing form and FIG. 2 a negative drawing form.

Nach Fig 1 wird eine Folie 1 über eine positiven Ziehform 2 einer Vakuum-Tiefziehanlage tiefgezogen. Über der Ziehform 2 ist ein Oberstempel 3 angeordnet, der mit einem Prägewerkzeug 4 versehen ist Unmittelbar anschließend an den Tiefziehvorgang wird unter Ausnutzung der Folienwarme mit dem Oberstempel 3 die Prägung der Folie t vorgenommen Die Folie bleibt während des Prägevorganges auf der Ziehform 2 liegen. Gegebenenfalls kann, wie aus Fig. 1 ersichtlich ist, in der Ziehform 2 im Bereich der vorgesehenen Prägung eine elastische Einlage 5 angeordnet sein.According to Fig. 1, a film 1 is over a positive drawing form 2 a Vacuum deep drawing machine deep drawn. An upper punch 3 is arranged above the drawing mold 2, which is provided with an embossing tool 4 Immediately following the deep-drawing process the embossing of the film is made using the film heat with the upper punch 3 t made The film remains on the draw form 2 during the embossing process. Optionally, as can be seen from FIG. 1, in the drawing mold 2 in the area the intended embossing an elastic insert 5 can be arranged.

Nach Fig. 2 wird die Folie 1 in einer negativen Ziehform 2 einer Vakuum-Tiefziehanlage tiefgezogen. Um unter Ausnutzung der Folienwärme sogleich eine vorgesehene Prägung vornehmen zu können, ist in der Ziehform 2 ein Prägewerkzeug 4 angeordnet Über der Ziehform 2 ist ein Oberstempel 3 mit einer elatischen Zwischenlage 5 vorgesehen, der den Prägedruck aufbringt.According to FIG. 2, the film 1 is in a negative drawing mold 2 of a vacuum deep-drawing system deep drawn. In order to immediately create a planned embossing using the heat of the foil to be able to make, an embossing tool 4 is arranged in the drawing mold 2 above the Drawing mold 2, an upper punch 3 with an elastic intermediate layer 5 is provided, who applies the embossing pressure.

Das Prägewerkzeug kann Je nach Erfordernis heizbar ausgeführt werden.The embossing tool can be designed to be heatable, depending on requirements.
