Abstract

The method involves guiding a non-woven insert material i.e. polyurethane non-woven web, between a cutting die (20) and a cutter (16) i.e. knife edge seal, which has a cutting surface (44), where the web is made of thermoplastic polyurethane based on polyester and polyether. The die and the cutter are fed to each other in a direction perpendicular to a plane of the material such that the cutter is partially engaged to punched openings of the die. The material is separated under formation of the insert. The die and cutter are held at temperature at which partial melting of the material occurs. An independent claim is also included for a device for stamping out inserts from a non-woven insert material.
