Web winding device and method

A web winding device for winding a material web into a winding roll, the device comprising:

• a rotatably driven first support roller having a circumferential shell and an end face on an axial end of said circumferential shell, said shell having a plurality of shell openings extending therethrough;
• a plurality of conduits axially disposed within said first support roller and axially extending to said end face, said shell openings communicating with said conduit whereupon at said end face, said plurality of conduits is adapted to be in sequential communication with a suction device over a portion of the rotation of said first support roller;
• a second support roller;
• a winding bed area defined by said first and said second support rollers;
• a winding bed pressurization device configured to provide pressure in said winding bed area;
• and
• a seal stationary and fixedly mounted to seal said end face, said conduits in communication with said seal at a portion of the rotation of said first support roller.

A web winding device for winding a material web into a winding roll, the device comprising:

• a rotatably driven first support roller having a circumferential shell and opposed ends, said shell having a plurality of shell openings extending therethrough;
• an end face disposed at one of said opposed ends of said first support roller;
• a plurality of conduits axially disposed within said first support roller and axially extending to said end face;
• a second support roller;
• a winding bed area defined by said first and said second support roller, and adapted to support the winding roll;
• and
• a suction device fixedly mounted to said end face, said suction device defining a suction zone upstream from said winding bed area with respect to the direction of rotation of said first roller, said plurality of conduits adapted to be in sequential communication with said suction device over a portion of the rotation of said first support roller, said suction zone being further adapted to provide suctional force through said conduits in sequential communication with said suction device over a portion of the rotation of said first support roller;
• wherein said end face of said first support roller has a seal adjacent to said conduits, said conduits being sequentially adjacent to said seal over a portion of the rotation of said first support roller, said seal preventing the passage of gas through said shell openings in communication with said winding bed area.

A web winding device for winding a material web into a winding roll, the device comprising:

• a rotatably driven first support roller having a circumferential shell and opposed ends, said shell having an outer surface, an inner surface and further having a plurality of shell openings therethrough;
• a end face disposed at one of said opposed ends of said first support roller;
• a plurality of conduits axially disposed within said first support roller and axially extending to said end face, at least one of said plurality of shell openings communicating with each said conduit;
• a second support roller;
• a winding bed area defined by said first and said second support roller, and adapted to support the winding roll, said winding bed area further having a sealing box for sealing said winding bed area;
• and
• a roller pressurization device in communication with said end face, said conduits being in sequential communication with said roller pressurization device, said roller pressurization device being adapted to pressurize said winding bed area by providing pressurized gas to said conduits at a portion of the rotation of said first support roller.

A method of winding a material web into a winding roll, the winding roll being supported by a first and a second rotating support roller defining a winding bed area, the first support roller having a circumferential shell and opposed ends, the shell having a plurality of shell openings extending therethrough and being in communication with a plurality of conduits axially disposed within the circumferential shell, an end face adjacent to one opposed end of the support roller, the conduits in communication with the end face, a suction device fixedly mounted to a portion the end face at a portion of the rotation of the first support roller, said method comprising:

• rotating the conduits such that the conduits sequentially communicate with the suction device, over a portion of the rotation of the first support roller;
• providing suctional force through the conduits in communication with the suction device;
• sealing the winding bed area;
• sequentially moving the conduits in communication with a roller pressurization device, over a portion of the rotation of the first support roller;
• and
• pressurizing the winding bed area by providing pressurized gas through the conduits in communication with the roller pressurization device.

A method of winding a material web into a winding roll, the winding roll being supported by a first and a second rotating support roller defining a winding bed area, the first support roller having a circumferential shell and opposed ends, the shell having a plurality of shell openings extending therethrough and being in communication with a plurality of conduits axially disposed within the circumferential shell, an end face adjacent to one opposed end of the support roller, the conduits in communication with the end face, a suction device fixedly mounted to a portion the end face at a portion of the rotation of the first support roller, said method comprising:

• rotating the conduits such that the conduits sequentially communicate with the suction device, over a portion of the rotation of the first support roller;
• providing suctional force through the conduits in communication with the suction device;
• sealing the winding bed area;
• sequentially moving the conduits in communication with a flat seal, over a portion of the rotation of the first support roller;
• and
• sealing the shell openings in communication with the conduits in communication with the flat seal.
