  • Patent number: 8522961
    Abstract: A two-material conveyor belt module and a method for making it. A conveyor belt module comprises a rigid thermoplastic link substrate topped with a high-friction layer made of a resilient material. A dense array of teeth protrudes upward from the link substrate. The resilient material is overmolded onto the link substrate at a temperature high enough to melt the ends of the teeth. The melted ends of the teeth mix with the resilient material to form a bond firmly retaining the high-friction layer atop the substrate.
