摘要

The present invention relates to a method for flanging an at least two-ply material (1, 2; 301, 302, 306, 307) with at least one metal foil ply and an additional ply comprising the steps of: defining an inner circumferential edge portion (8) of the at least two-ply material (1 , 2; 301, 302, 306, 307) spaced from an outer peripheral edge portion (9) from a peripheral boundary edge of the at least two-ply material (1,2, 301, 302, 306, 307), displacing the fixed inner peripheral edge portion (8 and an inverting member (14) relative to each other for angling the outer peripheral edge portion (9) against the inner peripheral edge portion (8) so that the inner peripheral edge portion (8) and the outer peripheral edge portion (9) make an angle of about 90 ° or less therebetween enclosing, and folding the outer peripheral edge portion (9) against the inner peripheral edge portion (8) by means of a Bördelementes (17, 18, 21), so that the two sections (8, 9) abut each other substantially flattened at least in sections. The method according to the invention specifies a simplified method for flanging an at least two-ply material. According to further subsidiary aspects of the invention, a method for producing a bag for a pouch battery, and a method for producing a temperature control unit will be specified. Furthermore, a pouch battery with a pocket made of an at least two-ply material and a tempering unit made of an at least two-ply material (1, 2; 301, 302, 306, 307) with at least one metal foil ply and an additional ply are specified.
