Patent number: 6702926Abstract: A wire section for forming a multi-ply fiber web. The wire section includes a first belt which advances a first fiber ply toward a couch roll defining a combining section. A twin-wire zone of the wire section includes first and second wires between which a second fiber ply is initially formed in a gap former. The second wire separates from the first wire and then the first wire supporting the second fiber ply meets the first belt supporting the first fiber ply at the couch roll of the combining section to form the multi-ply fiber web. The twin-wire part is arranged upstream of the combining section along the running direction of the first belt.

Patent number: 5163364Abstract: Calendering takes place in a calendering zone which operates under pressure with application of temperature and moisture. The desired smoothness is achieved with a correspondingly long dwell time of the material web in a correspondingly long calendering zone in view of the speed of web travel. A web which is still wet is guided between parallel heatable surfaces which are arranged on both sides of the web and face each other through the web and can each be pressed against the web. The surfaces are designed to form and hold a given precise contour of the calendering zone over its full length. One surface is constructed e.g. as a casing of a heated roller and the second surface is constructed as an endless flexible belt which can be pressed in a direction towards the roller casing by means of a concave supporting element. If wished, the web can be calendered on both sides with the method.Type: GrantFiled: October 19, 1989Date of Patent: November 17, 1992Assignee: Sulzer-Escher Wyss GmbHInventors: Alfred Bubik, Hans Dahl, Rudiger Kurtz, Herbert Holik, Peter Mirsberger, Harald Hess

Patent number: 5071513Abstract: At least two substantially parallel rows of adjustable pressure elements cooperate with a heatable counter element like a counter roll and are arranged immediately consecutive but separate from each other to define at least two pressing sections of an extended pressing zone through which a water-containing fibrous web is passed conjointly with a water absorbing porous band or felt in a predeterminate travel direction. Pressures and temperatures in each one of the at least two pressing sections of the extended pressing zone are adjusted such that water is displaced from the fibrous web under the combined action of pressure and steam which is formed in the extended pressing zone in a controlled manner and without damage to the fibrous web due to explosion-like flash evaporation.Type: GrantFiled: January 23, 1990Date of Patent: December 10, 1991Assignee: Sulzer-Escher Wyss GMBHInventors: Reinhard Bluhm, Herbert Holik, Peter Mirsberger

Patent number: 4662992Abstract: In a particularly simple construction a twin-wire papermaking machine possesses a reduced number of rolls as well as a compact arrangement. The foregoing and the greatest possible velocity of a through-passed paper web can be obtained by employing non-suction rolls, instead of suction rolls, in a pressing section of such papermaking machine, by upwardly entraining the paper web conjointly with a top or upper wire of a twin wire arrangement and by transferring the paper web to a pressing roll having a smooth surface, and furthermore, by providing at the pressing roll an extended or wide-nip supporting shoe by means of which the paper web is dewatered in an extended pressing nip zone. Advantageously, the dewatered paper web is taken off from the surface of the pressing roll in a downward direction and fed to a drying section of the papermaking machine. The drying section may be arranged below the pressing section and directly adjacent the bottom or lower wire of the twin wire arrangement.Type: GrantFiled: May 16, 1985Date of Patent: May 5, 1987Assignee: Sulzer-Escher Wyss GmbHInventor: Peter Mirsberger

Patent number: 4661206Abstract: In a wet press for dewatering a web of material, for instance a paper web, a contact pressure device is provided which presses against a rotating roll and exerts an incrementally increasing pressure in the direction of travel of the paper web. The contact pressure device comprises only a single pressure element arranged in the direction of travel of the paper web. The pressure element has two or more pressure pockets arranged sequentially in the direction of web travel and which are connected with a common pressure chamber by conduits. The increasing contact pressure is attained by arranging the pressure element unsymmetrically in relation to the pressure chamber. The effective pressure cross-sectional areas of pressure pockets arranged sequentially in the direction of web travel can additionally be reduced in the direction of web travel or the cross-sections of the associated bores can be increased.Type: GrantFiled: January 28, 1985Date of Patent: April 28, 1987Assignee: Sulzer-Escher Wyss GmbHInventors: Peter Heitmann, Herbert Holik, Peter Mirsberger

Patent number: 4570314Abstract: A press roll contains a stationary roll support or beam and a roll shell rotatable about the stationary roll support, the roll shell being formed of an easily deformable material. The roll shell is supported at a support surface located at the region of the roll support. This support surface can be convex and possess a larger radius than the radius of the roll shell, can be planar or concave. Guide surfaces possessing a convex profile laterally merge at the support surface. The support surface and the guide surfaces are provided with a pressure lubrication and possibly with hydrostatic bearing pockets. A support part or element can be movable in relation to the stationary roll support or beam in the manner of controlled deflection rolls.Type: GrantFiled: June 4, 1982Date of Patent: February 18, 1986Assignee: Escher Wyss AktiengesellschaftInventors: Herbert Holik, Helmut Hund, Peter Mirsberger
