Abstract:
1. A conveyor belt module comprising: a rigid link substrate molded of a low-friction plastic material and having hinge elements at opposite ends of the rigid link substrate for connecting hingedly with hinge elements of adjacent rigid link substrates, a load-bearing surface between the opposite ends of the rigid link substrate, and an array of thin teeth upstanding from the load-bearing surface, wherein each tooth has a base proximate the load-bearing surface and a distal tip end; a high-friction layer made of a resilient material molded atop the load-bearing surface of the rigid link substrate at a temperature sufficiently high and applied long enough to melt the distal tip ends of the teeth in contact with the resilient material without melting the bases of the teeth during the molding of the high-friction layer onto the rigid link substrate and to cause the melted distal tip ends to mix with the resilient material to retain the high-friction layer atop the load-bearing surface.
