Abstract
An antistatic driving belt having a durable destaticizing function and long surface life. A cushion rubber layer is disposed between a tension rubber layer and a compression rubber layer, and tension members are buried in the cushion rubber layer. A layer of conductive rubber blended with conductive material and having a high abrasion resistance is arranged on the underside of the cushion rubber layer. The ends of the layer of conductive rubber are exposed on both sides of the belt. Preferably, the conductive rubber layer is formed of rubber containing 5 to 50 parts by weight of conductive material to 100 parts by weight of rubber. The conductive rubber layer should be 0.1 mm or thicker, and should have a thickness less than half the total thickness of the compression layer.
Claims5
