A thermoplastic endless belt has a smooth outer surface and an inner surface in which is formed a plurality of holes spaced at a given hole pitch. The holes are adapted to engage a pulley with circumferentially spaced pins having a pin pitch greater than the hole pitch. According to one embodiment, the holes are oblong, and the pins are cylindrical. Because of the difference in the hole pitch and the pin pitch and relative dimensions of the hole and pins, the belt can stretch to a maximum allowable elongation without detrimentally affecting the operation of the conveyor.
