Abstract:
A belt positioning system for positioning 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 tapered flange. The tapered flange is operatively connected to an axial end of a specific one of the plurality of generally parallel rollers, and includes a generally planar contact surface and an angled guide surface. The generally planar contact surface extends generally perpendicular to the axial direction to contact an adjoining edge of the belt. The angled guide surface extends radially outward from the contact surface and has a diameter increasing outward in the axial direction.
