Guide roller and conveyor-belt assembly provided therewith

摘要

The present invention relates to a guide roller 3 for a conveyor-belt assembly 1 having an endless conveyor belt which is guided over this roller and a second support which is substantially parallel to the roller. The roller surface of the guide roller 3 is composed of a number of segments 8 which are distributed over its surface in the axial direction, can be displaced in the axial direction and are locked against rotation about the guide-roller axle 7. An axially displaced segment 8 which is no longer surrounded by the belt 4 is returned to its starting position by a restoring member as the rotation of the roller continues. <IMAGE>
