Method for the production of bags

摘要

A process for manufacturing a bag from a polymer and/or metal film material provides a bag that has four outer walls connected by four seams and that has a sealed lower end. The bag-forming material is fed in the form of a film web that is wound up on a roll to an unwinding station of a bottom forming device that separates the unwound film web into film segments, connects the film segments, and seals at least one end of the connected segments to form the bag.
