Abstract

The present invention relates to a method of producing foil bags, wherein at least two foils are supplied that serve as side foils of the foil bags, the foils are connected to each other and then cut into individual foil bags, wherein possibly existing differences in the amounts of foil materials provided by the at least two foils in the feed direction for a respective foil bag are eliminated by stretching the foil that provides the smaller amount of foil material for a foil bag, and to a bag-producing apparatus for performing the method.
