The invention relates to a device for the production of energy storage units, comprising feed means (100, 200, 300) for single layers or multilayered films (90, 40, 92), means (530) for driving said means such that they can be unwound, means (C) for combining said films to form a complex (96), and a mandrel (610) which is adapted in such a way that the films can be wound in the form of a multilayered winding (10, 20, 30, 40, 50, 60), characterized in that the inventive device comprises first cutting means (270) for cutting one or more of the layer(s) (40) forming the complex in a manner which is transversal in respect to the direction in which they are unwound, and second cutting means (550) for cutting the remaining layers (10, 20, 30, 50, 60) in a manner which is transversal in relation to the direction in which they are unwound, such that the layers cut (40) by the first means (270) are set back in relation to the other layers (10, 20, 30, 50, 60) at one end of the winding of the complex (96). The invention also relates to a method for the production of energy storage units and to said units thus obtained. |
