ABSTRACT:
A winding machine for winding a traveling web of paper or the like. A carrying drum extends across the web. A first pair of primary levers supports the pins at the end of a cylinder on which the web is to be wound. The primary levers have one end with a fork for receiving a respective journal pin of the cylinder and another end that is mounted in the region of but eccentric to the axis of the carrying drum. The primary levers swing the cylinder over approximately 90.degree. around the carrying drum to a second position. A second pair of secondary swing levers pick up the cylinder at the second position and move it to a third position along a substantially horizontal second pathway. A first drive connected with one primary lever introduces a moment of rotation to the axis of the cylinder moving along the primary path. A sensor detects the radial position of the cylinder and a setting device adjusts the radial position of the first drive in order to align it with the cylinder. There may be a secondary drive for imparting rotation to the cylinder over the secondary path.
