  • Conveyor belt rollers with two surface materials
    Patent number: 8746442
    Abstract: A conveyor belt and a belt module having multiple roller sets, each roller set including a bottom roller in contact with an axially elongated two-material top roller. The periphery of the top roller has a high-friction peripheral surface separated by a central durable, low-friction peripheral surface in contact with the bottom roller. Driving the bottom roller in a first direction causes rotation of the top roller in an opposite angular direction.
