FILMS AND COMPOUND FILMS WITH AN EMBOSSED PATTERN, PARTICULARLY FOR PRODUCING ELECTROCHEMICAL COMPONENTS

摘要

The invention relates to films which are provided with an embossed pattern a nd are connected to additional films. Said films are characterized by the fact that the embossment of each film defines at least one dividing line (3, 4) which is interrupted in a regular pattern by means of steps that have a smaller width than the average distance between two steps. Preferably, the width of each step is smaller than the distance of said step to the adjacent steps. The inventive films can be arranged into compounds in which the films are placed on top of each other in a staggered manner such that the steps of a first film (A) and the steps of a second film (B) do not lie on top of each other, whereby material of individual, different films is prevented from smearing during subsequent cutting of the compound films (C) into individual elements while contact between the different materials is prevented.
