ABSTRACT:
Method for manufacture of links designed to be interconnected to form a conveyor and including the following steps;mold a body of the link of rigid low-friction material with said body being provided with projections protruding from one of its faces, andhot-mold on at least part of said face cooled to hardening a high-friction malleable material for formation of a skidproof covering with the high-friction material during molding striking said projections and being injected at a temperature higher than the softening temperature of the rigid material in such a manner as to cause plastic deformation of the projections that originate undercuts with the deformed projections upon completed molding remaining incorporated in the high-friction material to create a mechanical interconnection between the covering and the rigid body.
