Belt support and control system

摘要

An apparatus in which lateral movement of a moving belt is controlled so that the belt moves in a pre-determined path. The apparatus includes at least one moving member having a plurality of spaced, flexible discs extending outwardly from the exterior surface thereof. The portion or segment of the disc contacting the region of the belt passing thereover provides support therefor. Preventing the belt from deviating laterally from the pre-determined path deflects the portion or segments of the discs providing support for the belt. The deflected portion of the disc returns to the undeflected condition when not supporting the belt. In this manner, the maximum force applied to the belt never exceeds the minimum force required to buckle the belt.
