Abstract
A conveyor comprises a drive pulley, an idler spaced from the drive pulley, and an endless thermoplastic belt wrapped around the drive pulley and the idler. The endless thermoplastic belt has a load-carrying span adapted to move from the idler to the drive pulley and a return span adapted to move from the drive pulley to the idler. The conveyor further includes a roller on the return span near the idler, and the weight of the roller acting on the return span tends to keep the endless thermoplastic belt engaged with the idler.
