Abstract
The invention relates to an apparatus for welding a joining region of a foil to a connecting part, particularly two foils to a tubular connecting part. Conventional apparatuses are associated with the risk of steep workpiece flanges causing uncontrolled weaknesses in the foil and the weld seam. According to the invention, an extension of the foil outside of the joining region is provided in a controlled manner such that the foil has spare length. In this connection, the invention further relates to the use of a foil, to a method for welding, to a system for producing bag, and to a bag.
