Abstract
Conveyors are disclosed herein. An embodiment of a conveyor includes a bed having a first end and a second end, wherein a belt is slidable on the bed. The belt is in a first portion of its travel when it is located adjacent the bed and the belt is in a second portion of its travel when it is located opposite the bed. A curve is located on the first end of the bed, wherein the belt contacts at least a portion of the curve as the belt transitions between the first portion of travel and the second portion of travel.
