Abstract
A conveyor of the type having a flexible endless belt with generally horizontal top and lower return levels is movably supported for delivering materials between load and unload stations. A plurality of transversely spaced pairs of wheeled trolleys or other types of slide mechanisms are movably mounted on spaced horizontal guide rails and are attached to opposite sides of the conveyor belt by brackets and small sections of flexible belt material. Each of the trolleys has a pair of horizontally mounted wheels and a pair of vertically mounted wheels which move with the conveyor belt along the guide rails to maintain accurate guidance and tracking of the conveyor belt. One of the trolleys of each pair is spring biased to compensate for possible variations in the guide rails.
