ABSTRACT A roughing machine for roughing the margin of an upper that is moved past a roughing tool of the roughing machine. The roughing tool is incorporated in a roughing tool assembly that is yieldably urged downwardly against the upper margin under relatively low pressure. A damper mechanism has a follower element in engagement with the roughing tool assembly. The damper mechanism is so constructed that the follower element provides a resistance to upward movement of the roughing tool assembly of a relatively high magnitude and a downward force of a relatively low magnitude is imparted to the follower element.
