Zusammenfassung:	A method and apparatus are provided for securing a plastic fastening profile, such as is used on reclosable plastic containers, to a traveling plastic film web. A freshly extruded hot fastener profile (30) is guided into convergence with a preformed traveling film web (10). The profile and web are joined together in an area (32) in which the web is insulated. Only the heat from the fastener profile is used to fuse the surface of the web and secure the profile to the web.
