High temperature conveyor belt

摘要

A high temperature conveyor belt is provided having a non-metallic conveying surface which will not scratch, abrade or otherwise mar the surface of a product being carried on the belt through a furnace and which will not contaminate the product. In one embodiment, the conveyor comprises a high temperature fabric belt attached to a metal belt which may be a conventional woven metal conveyor belt. In another embodiment, the conveyor is composed of a non-metallic high temperature strand which is woven or threaded through a metal belt to provide a non-metallic conveying surface. In a further embodiment, the non-metallic product support elements are coupled to roller chains at each side of the furnace chamber and which are cooperative with a drive mechanism to transport the conveyor through the furnace. The roller chains can be located outside of the furnace chamber to avoid exposure to the high temperature of the furnace chamber.
