Abstract
A conveyor comprises an endless thermoplastic belt having a substantially flat surface on one side of the belt and a plurality of teeth on the other side of the belt. The teeth are adapted to be driven without tension around a drive sprocket and an idler. The conveyor further includes means to cause the belt to form a longitudinal trough between the drive sprocket and the idler to retain conveyed items on the belt. The means can comprise a discontinuity in the teeth, shortened teeth, and/or guides that apply a force to the edges of the belt.
