ABSTRACT:
A rider roll system for exerting an even nip load force along the surface of a roll of paper being wound from a continuous on-coming web in a winder comprises a plurality of rider roll wheel elements, each of which is connected to a common source of hydraulic pressure to provide the same rolling nip force against the wound paper roll. The rider roll wheel elements are mounted to a beam which is translationally movable above the wound paper roll. The beam and individual rider roll wheel elements are moved upwardly as a function of the increase in the diameter of the wound paper roll. The relationship of the beam movement relative to the diameter of the wound paper roll is controlled by a programmable logic controller. The individual wheel elements are loaded against a counter-balance force so as to provide equal, but cushioned, nip force against the surface of the wound paper roll at short intervals along its length. The magnitude of the evenly applied nip load force is also controlled as a function of the wound paper roll diameter.
