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.
