ABSTRACT:
A method for making weather strips in which a polyurethane film is positioned along an anvil having longitudinal parallel spaced anvil surfaces and recesses therebetween with elongate channel-like portions of the film in the recesses. Resiliently compressible polyurethane foam is pressed against the polyurethane film along the anvil so that the foam is compressed against the anvil surfaces and extends into the channel-like portions of the film in the recesses. The compressed foam and film along the spaced anvil surfaces are then sonically welded to fuse the foam together in its compressed state and fuse the compressed foam to the film, and the fused foam and film are slit along the anvil surfaces to form separate weather strips.
