FIELD: shoe industry, in particular, process for manufacture of shoe sole consisting of two parts connected with one another through adhesive.
SUBSTANCE: method involves continuously forming rubber tread in mold; during curing procedure, applying adhesive directly onto rubber tread, said adhesive consisting of aqueous dispersion of thermoplastic polyurethane and activator, the latter causing cross-linking of thermoplastic polyurethane; evaporating water dispersed in adhesive; thereafter, applying polyurethane layer onto tread of cured rubber, said layer forming mid portion of sole. Adhesive preferably used in said method consists of aqueous dispersion of thermoplastic polyurethane combined with activator causing cross-linking of thermoplastic polyurethane.
EFFECT: increased efficiency by providing manufacture of composite sole for one and the same production cycle.
