Abstract
A flexible endless belt in a belt-type conveyor for an agricultural machine has a central rib bonded to its inside surface, the construction and cross section of the rib being similar to that of a power transmission-type V belt. The conveyor rollers have central V-shaped grooves to mate with the rib on the belt. The conveyor is driven through an end roller, power being transmitted to the belt by the combined frictions between the roller and the flat and V sections of the belt respectively. On an idler roller at the other end of the conveyor, a pair of raised annular ridges straddle the V-shaped groove, thus increasing belt tension adjacent the groove and ensuring that of the forces controlling the tracking of the belt on the rollers, those deriving from the V belt in the V-shaped groove are dominant so that the belt tracks straight and remains centered on the rollers.
