  • Precemented welt
    Patent number: 6205604
    Abstract: A precemented welt for shoe construction, and methods of making such a welt. The welt comprises a body section, and a solid adhesive surface layer which can be activated to form a bond. The adhesive does not activate at typical truck trailer temperatures, so the welt material can be easily shipped. In one embodiment, the adhesive comprises an aromatic polyurethane elastomer, which can be activated by heating the welt to a temperature of at least 225° F. for at least 30 seconds.
