ABSTRACT:
A winder for winding a running web on a winding drum having a journal at each end. Each one of a pair of primary levers has a fork at one end for receiving one of the journals. As the roll is progressively wound, the winding drum is swivelable from a first position situated generally above the backing roll to a second position offset from the first position by an angle of about 90 degrees. The winding drum is received from the primary levers at a pair of secondary levers at the second position. A generally horizontal guideway for the drum extends from the second position to a third position. The roll and the winding drum are forced onto the backing roll by a contact pressure device. A driven cam plate is coordinated with each of the primary levers so that a cam plate and the primary lever at least partially pass a primary section between said first and second positions, thereby relieving part of the pressure on the winding drum and roll wound thereon in accordance with the contour of the roll, and according to the distance of travel negotiated from the first position to the second position.
