Abstract (en)

[origin: EP1947045A2] The method involves moving foil e.g. double-wound foil, layers i.e. laterally open foil layers, relative to each other, and weakening a cross section of one of the foil layers in an upstream step. Foil layers are cut in the upstream step by a cutter or a laser and are fixed on a side during separation of the foil layers by relative motion. The foil layers are partially welded before the separation, and the relative motion takes place by bending via a roll and an eccentric tappet and a wedge. Independent claims are also included for the following: (1) a device for separation of foils (2) a system for welding an insertion piece (3) a method for manufacturing a product.
