Publication number: 20030092548Abstract: The present invention is directed to a roll cover for a calender or press roll for treating a material web. The roll cover includes a layer of elastomeric material having filaments running approximately longitudinally with respect to a web run direction and transversely to the web run direction embedded for reinforcement, and at least one layer of additional reinforcing filaments embedded in at least some sections of the elastomeric layer. The additional reinforcing filaments run at an angle between 20° and 70° with respect to the web run direction. The layer is arranged to form roll ends connectable to a roll axle. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.Type: ApplicationFiled: November 8, 2002Publication date: May 15, 2003Applicant: Voith Paper Patent GmbHInventors: Uwe Matuschczyk, Hermann Reichert

Patent number: 6149771Abstract: Process for manufacturing a press jacket of flexible material for a press device and a press jacket that is adapted to drain a material web in a press opening in a paper making machine. The process includes arranging at least one reinforcing fiber in a jacket material that forms the press jacket so that the reinforcing fibers are arranged to run substantially in a peripheral direction of the press jacket, forming grooves to run substantially in the peripheral direction in at least one surface of the press jacket, and orienting the arrangment of the at least one reinforcing fiber and the formation of the grooves relative to each other so that the at least one reinforcing fiber and the grooves do not run radially superposed in a same direction.Type: GrantFiled: May 28, 1998Date of Patent: November 21, 2000Assignee: Voith Sulzer Papiermaschinen GmbHInventor: Uwe Matuschczyk

Patent number: 6065396Abstract: Press device to treat a fibrous pulp web that may include a shoe press roll and a mating roll. The shoe press roll and the mating roll may be positioned to form a press nip, and at least one endless belt guided through the press nip and forming a substantially non-flexible and rigid drive element at least partially driving the press device.Type: GrantFiled: October 15, 1997Date of Patent: May 23, 2000Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Christian Schiel, Andreas Schuette, Wolfgang Schuwerk, Joachim Grabscheid, Werner Leitenberger, Uwe Matuschczyk, Christian Steger

Patent number: 6029570Abstract: Press jacket for a press device that drains a material web in a press nip having a press nip length. The press jacket includes blind holes for water absorption that open to a jacket surface of the press jacket and channels extending at least sectionally in a web run direction being coupled to the blind holes. The channels have a length in the web run direction greater than a length of the press nip.Type: GrantFiled: May 28, 1998Date of Patent: February 29, 2000Assignee: Voith Sulzer Papiermaschinen GmbHInventor: Uwe Matuschczyk

Patent number: 6030503Abstract: Press sleeve for de-watering a material sheet in a press nip having a width. The press sleeve may extend transverse to a travel direction of the material sheet and may include a flexible material, a pressing area, adapted to form the press nip, having two ends, end sections positioned adjacent to each end of the pressing areas, and recesses located on an exterior surface to take up water. The press sleeve may also include outer sections including portions of the pressing area and portions of the end section, an inner section including a portion located between the outer sections. The recesses located within the outer sections may include a plurality of recesses having a limited length in the travel direction and the recesses located within the inner section may include grooves substantially extending endlessly in the travel direction.Type: GrantFiled: August 25, 1997Date of Patent: February 29, 2000Assignee: Voith Sulzer Papiermaschinen GmbHInventor: Uwe Matuschczyk

Patent number: 5943951Abstract: Flexible press sleeve for a press roll for treating a web includes an inside surface including a longitudinal press area adapted to be pressurized with a press shoe by directing pressure radially outward, and a flexible section on at least one end of the press area having a greater flexibility than a flexibility of the press sleeve outside the flexible section, without causing a significant weakening of the press sleeve within the flexible section. A press shoe includes the press roll and a mating roll forming a press opening with the press roll. A method of treating a web includes draining a fibrous pulp web by using the press shoe.Type: GrantFiled: December 16, 1997Date of Patent: August 31, 1999Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Josef Muellner, Uwe Matuschczyk

Patent number: 5342277Abstract: A roll, especially for press rolls in paper machines includes an elastomeric shell separated from a roll core. The roll is characterized by the fact that, in the region of the axial end of the roll core, there is a large reduction in thickness of the roll shell, with the reduced thickness provided substantially at the axial end of the roll shell or in an annular transition region spaced from and near the end of the shell.Type: GrantFiled: November 9, 1992Date of Patent: August 30, 1994Assignee: J. M. Voith GmbHInventors: Karl Steiner, Uwe Matuschczyk

Patent number: 5320702Abstract: A press blanket for a press device in a paper making machine, or the like, is formed of an elastomeric blanket material and fully embedded layers of reinforcement threads. The radially inner layer is formed of longitudinal threads which extend parallel to the axis of the press blanket. The radially outer layer is formed of circumferential threads which are wound in the direction of blanket motion and are wound generally helically. The threads are fully surrounded by the layer of homogeneous elastomeric material, that is formed from a single pouring. The circumferential threads have a diameter of at most 1/500 of the outside diameter of the fully rounded press blanket. In a unit area of the press blanket, the tensile strength of the circumferential threads is at least 40% greater than the tensile strength of the longitudinal threads.Type: GrantFiled: March 31, 1992Date of Patent: June 14, 1994Assignee: J.M. Voith GmbHInventors: Uwe Matuschczyk, Karl Steiner, Harald Aufrecht, Christian Schiel
