Abstract

Official abstract text for this publication.

A belt tracking system for controlling the lateral position of a movable belt entrained about a plurality of generally parallel rollers for moving in a trans-axial direction perpendicular to an axial direction in which the rollers extend parallel to each other includes a roller shaft, a stationary member, a slidable member, and a biasing mechanism. The roller shaft extends outward in the axial direction from an axial end of a specific one of the plurality of generally parallel rollers. The stationary member is fixed in position adjacent to the roller shaft to define a first interfacial surface therealong. The slidable member is co-movably coupled with the roller shaft to define a second interfacial surface therealong inclined relative to the axial direction. The biasing mechanism is connected to the roller shaft to press the slidable member against the stationary member.
