Abstract

Shoe soles, incorporating a core sole made of hide with a coating of pigmented PVC and a wear sole made of abrasion resistant rubber, are assembled by die cutting the component layers to shape and then subjecting them to intense high frequency heating while superimposed to fuse and bond the interface by a state of thermal shock. Offers more rapid and cheaper construction than assembly of hand lasted hide and rubber soles by means of stitching and/or chemical adhesives. Cost saving of about 50% quoted. Facilitates incorporation of non-skid components or surface profiles. The mould tool should be made of matl. of low dielectric loss. Pref. at least one face of the mould carries a relief pattern to be generated on the visible portion of the rubber wear sole; pref. the pattern enhances the grip of the mould tool on the rubber insert.
