Abstract

The PTFE is applied tautly against the working surface of the welding tool in the form of a film strip, or sintered into a heat-resistant weave such as metal gauze of a glass fibre material. The design allows clean seam welding in thermoplastic semi-finished products particularly on automatic processes.
