Patent number: 5431787Abstract: The press section of a papermaking machine for dewatering a paper web comprises two separate, successively arranged extended nip press locations. Both of the extended nip press locations contain at least one respective felt which travels together with the paper web through the associated extended nip press location. The paper web is guided from the first extended nip press location to a web removal device contacted by an upper felt of the second extended nip press location, and from that location the paper web can move to the second extended nip press location.Type: GrantFiled: October 25, 1993Date of Patent: July 11, 1995Assignee: Sulzer-Escher Wyss GmbHInventors: Heinz Braun, Peter Mirsberger

Patent number: 5282933Abstract: The wet section of a twin wire papermaking machine is provided with an open forming roll at the lower wire and with the combination of a suction box at the lower wire and a vacuum suction box at the upper wire. Furthermore, by selecting the elevational position or level of the individual wire sections there can be obtained particularly advantageous conditions for the operation of the papermaking machine throughout a wide field of application, especially heavy types of paper at relatively low operating velocities of the papermaking machine. Gap-former and hybrid-former constructions of the papermaking machine are possible.Type: GrantFiled: November 19, 1991Date of Patent: February 1, 1994Assignee: Sulzer Escher Wyss GmbHInventors: Alfred Bubik, Hans Dahl, Karl Muller, Heinz Braun, Thomas Schaible, Helmut Storr, Heinz Steckenreuter

Patent number: 5225043Abstract: A twin screen paper forming apparatus is provided having upper and lower screens moving in a first direction and wrapping around a portion of a leading forming roller positioned at the beginning of a forming zone where the upper and lower screens converge to form a twin screen. At least one stationary forming element is positioned downstream of the leading forming roller to contact with the lower screen. A water guide element is also located in the region of the forming zone approximately at the start of the forming zone. At least one forming rail contacts the upper screen and a pulp suspension discharge nozzle is positioned, to prevent preliminary draining, upstream of the location where the upper and lower screens converge.Type: GrantFiled: December 4, 1991Date of Patent: July 6, 1993Assignee: Sulzer-Escher Wyss GmbHInventors: Heinz Braun, Alfred Bubnik, Herbert Holik, Rudiger Kurtz, Heinz Steckenreuter, Helmut Stieb, Jurgen Zenz

Patent number: 4425187Abstract: A twin-wire papermaking machine contains a headbox for forming a first fiber ply which is essentially downwardly dewatered at a section of a first wire. At the end of this wire section, forwardly or upstream of the inbound or on-running location of a second wire there is arranged a second headbox for forming a second fiber ply which is essentially upwardly dewatered along a subsequently arranged common path of both wires. The common path advantageously extends over an essentially water impervious, convex domed contact surface of a slide shoe and/or a jacket surface of a guide cylinder or roll. During operation, the second fiber ply is deposited upon the already extensively dewatered first fiber ply and upon passage through the common path of both wires this second fiber ply is dewatered upwardly away from the first fiber ply.Type: GrantFiled: April 1, 1982Date of Patent: January 10, 1984Assignee: Escher Wyss GmbHInventors: Frederick R. Armstrong, Heinz Braun, Alfred Bubik, Helmut Storr, Karl Turobin-Ort

Patent number: 4283023Abstract: A winder apparatus for a papermaking machine for winding-up a paper web onto a reel-spool, comprising an endless sieve or filter band arrangement which is guided over guide rolls, one of which serves as a drive roll. The band arrangement drives the reel-spool and the paper web which is wound thereon. As the drive roll there can be used the outermost guide roll viewed in the direction of driving of the reel-spool.Type: GrantFiled: October 20, 1980Date of Patent: August 11, 1981Assignee: Escher Wyss GmbHInventors: Heinz Braun, Karl Kiesel, Wolf-Gunter Stotz

Patent number: 4143828Abstract: A winder for a papermaking machine comprising a cylinder over which there is guided the paper web which is to be wound-up. A reel-spool receives the wound-up paper roll or package and a contact or press device presses the reel-spool in the direction of the cylinder. An endless band arrangement is guided such that it extends over the cylinder between its surface and the paper web, the band arrangement in conjunction with the paper web being wrapped about part of the circumference or outer surface of the cylinder and extends between the cylinder and the reel-spool or, as the case may be, the paper roll or package wound upon the reel-spool. The band arrangement also encloses the paper roll or the reel-spool along part of its circumference.Type: GrantFiled: April 24, 1978Date of Patent: March 13, 1979Assignee: Escher Wyss GmbHInventors: Heinz Braun, Karl Kiesel, Wolf-Gunter Stotz

Patent number: 4004968Abstract: A wire is passed over the suction breast roll between the formed paper web and the doffer belt or the previously formed paper webs and doffer belt. The doffer felt is disposed in an unencumbered fashion over each of a plurality of consecutive suction breast rolls. The wire is removed from the web at a downstream point outside the dewatering influence of each breast roll. Stripping of the wire from the paper web is aided by various suction devices or couch rolls at this latter point.Type: GrantFiled: May 27, 1975Date of Patent: January 25, 1977Assignee: Escher Wyss G.m.b.H.Inventors: Heinz Braun, Hans Dahl, Jost Hefter, Wolf-Gunter Stotz
