Abstract

Disclosed is a procedure for automatically tensioning and tracking belts, such as those used in recording processes. The system consists of an idler~roller resting against a belt, At either end of the idler is a straight bearing which rests in a slot and on a cain. The cam gives a linear displacement which enables one side at a time of the idler~ roller to move in a linear direction. The cam~smotion is controlled by a motor which is controlled by two photocells. The linkage is a spring/wire type. The motor wraps the wire around a pulley. The spring allows for tensioning.
