Embodiment Construction

[0018] image 3 with 4 The group separation, processing and feeding of film or sheet material 11 , 12 to a chute 5 , 20 is shown. Since these materials are mostly multi-layered, they are referred to as composite material films 11, 12 hereinafter. A strip of composite material film 10 etc. is supplied to a punch 2 and a cutting device 3 by means of a conveying device 1 . At the cutting device 3 place, the composite material films 11, 12 are cut into generally equal-length individual composite material films 11, 12 by the composite material film strip 10, and they are overlapped and supplied to the sheet conveyor belt 4. The trough 5 or directly feeds the trough 20 shown in FIG. 1 .

[0019] The composite film strip 10 , for example an adhesive plaster strip, comprises, for example, a protective film 16 , an adhesive plaster carrier, for example, and a single-sidedly coated active substance carrier 17 , for example in the form of an adhesive plaster, adhering thereto. The st...

Abstract

The invention relates to a method for grouping a multitude of film-like or sheet-like materials, which are stacked in a magazine (20) and which consist of at least one material layer, using at least one suction apparatus (42), which suctions the film-like or sheet-like materials in a clocked matter while removing them from the magazine, whereby one film-like or sheet-like material at a time directly rests with a portion of its surface that forms a contact surface against the suction device. To this end, one portion of the magazine contents consists of gas-impermeable film-like or sheet-like materials whereas another portion contains film-like or sheet-like materials that are each provided with at least one gas-permeable zone. The invention develops a method for grouping film-like or sheet-like materials during which a number of film-like or sheet-like materials can be grouped without impairing the speed of subsequent processing.

Description

technical field [0001] The invention relates to a method for grouping a plurality of film or sheet materials stacked in a chute, comprising at least one material layer, by means of at least one aspirator which rhythmically attracts the film or sheet materials And it is taken out from the trough, wherein at the same time a film or sheet material is directly attached to the suction device with the part of its surface forming a contact surface. Background technique [0002] Methods for separating film or sheet material stacked in troughs are known. A single film or sheet material is rhythmically taken out of the trough by a suction device and fed individually for further processing. [0003] If several film or sheet materials are to be further processed simultaneously, this requires, for example, several hoppers in which different film or sheet materials are stored. This is expensive and slows down further processing. Contents of the invention [0004] It is therefore the ...
