Abstract
Web winding device for winding a material web into a winding roll. The device comprises a rotatably driven first support roller having a circumferential shell and opposed ends, the shell having an outer surface, an inner surface and further having a plurality of shell openings therethrough. A second support roller is also provided. An end face is disposed at one of the opposed ends of the first support roller and a plurality of conduits are axially disposed within the first support roller and axially extend to the end face section, at least one of the plurality of shell openings communicating with each the conduit. A winding bed area is defined by the first and the second support roller, and adapted to support the winding roll. A suction device is mounted to the end face and provides suction to a portion of the surface of the shell. The suction device is fixed relative to the rotation of said first support roller. A pressurization device may also be used to pressurize the winding bed area. The conduits are in sequential communication with the suction device as the roller rotates. A method of winding a material web into a winding roll is also provided.
