VERFAHREN ZUR HERSTELLUNG VON FUSSBEKLEIDUNG

摘要

Method of making casual footwear including a knitted fabric upper, a woven insole portion, and an injection-molded sole is produced in a mold cycle of 45-second duration, as opposed to five or six minutes heretofore generally required, or the +2 minutes with the latest known materials. Molding conditions and materials are carefully controlled, and substantial penetration of the woven and knitted fabrics by the injected material is achieved. The woven insole portion prevents the flowing plastic from pushing the upper over the last. Ethylene/ethyl acrylate copolymer, polyvinyl chloride and styrene butadiene are preferred sole thermoplastics.
