PRODUCTION OF SHOE SOLE HAVING EMBOSSED SURFACE COMPRISING CROSSLINKED ETHYLENE-VINYL ACETATE COPOLYMER OF CLOSED CELL FOAM
Document Type and Number:
Japanese Patent JPS57177702
Kind Code:
A
Abstract:
An outsole with a relief-type profile is manufactured from a closed-cell foamed, crosslinked ethylene/vinyl acetate copolymer by a process in which the material used is shaped to give a slab, crosslinked and expanded by activation of a blowing agent contained therein and then subjected to a further heat treatment, the slab is split by at least one cut into several part slabs, after which the surface of a part slab is heated on one side or both sides to a temperature of at least 120 DEG C and at most 200 DEG C, with the proviso that the temperature does not exceed 75 DEG C at a depth which corresponds to the depth of the profile desired, after which stage each surface thus heated is then given a relief-type profile by the impression of an embossing ram which has been heated to a temperature of 65 to 80 DEG C.
