摘要

The workpiece (B) is trapped between two barrel- shaped rollers (1,2) which are rotated (A) in the same direction. The rollers are arranged at slightly different level and have their axes parallel to each other. The workpiece is in rolling contact and rotates in the opposite direction. The workpiece is in sliding contact with a straight support rail (3) along its length.
