Disclosed is a conveyor comprising two conveyor sections, each conveyor section having a frame extending generally longitudinally of the conveyor, a first splined shaft rotatable in an end of the frame, a second shaft rotatable in the other end of the frame, a first wheel on the first shaft and a mechanism for rotating the first wheel on one of the conveyor sections. A second wheel is on the second shaft and a belt is trained about the first and second wheels, the belt having a first side for engaging the first and second wheels and a second side for engaging an article conveyed along the conveyor. A relatively low friction surface exists between the first and second wheels and the first side of the belt lies adjacent the relatively low friction surface to be supported thereby when an article is conveyed along the conveyor. The two conveyor sections are coupled together, the coupling comprising first and second bearing rollers, the first roller having a splined center opening for engaging the splines on the first shaft for receiving the ends of the first shaft to synchronize the movements of the belts on the two conveyor sections. The spacing between the conveyor sections may be adjusted.
