Abstract
A conveyor belt tracking apparatus is provided for correcting the travel path of a laterally mistracking conveyor belt. In one form, an elongate tracking roller is rotatably mounted at end portions thereof to a pivotal support frame and extends across and below the belt. The pivotal support frame is mounted to a downstream pivot member so that belt mistracking toward one end portion of the tracking roller causes the one end portion to shift downstream and laterally outwardly to urge the belt toward the correct travel path. In one approach a downstream pivot connection between the pivot member and pivotal support frame is inclined upstream so that the end portion also shifts upwardly as it shifts downstream to urge the mistracking belt edge toward the correct travel path.
