Patent number: 7713385Abstract: Apparatus and method for treating a material web, which has at least one nip through which the material web is guided and which is formed between a first revolving, heated surface and a second revolving surface, it being possible for the first surface to be heated to at least 120° C. and both surfaces in the nip having the same direction of movement as the material web. Good surface quality of the material web is obtained by providing a box which bounds a space through which the material web is guided, the space being arranged after the first or after the last nip in the direction of movement of the web.Type: GrantFiled: December 16, 2005Date of Patent: May 11, 2010Assignee: Voith Paper Patent GmbHInventors: Jörg Rheims, Günter Bonk, Jochen Autrata

Patent number: 7287974Abstract: A calender arrangement for calendering a material web, in particular a paper web, having a shoe roll and a mating roll, between which an extended nip is formed, through which the material web can be guided. The shoe roll includes a revolving shell, which is fixed to two rotatably mounted terminating elements arranged at the ends and can be loaded in the direction of the mating roll via a press shoe matched to the outside of the mating roll. The shell includes a radially inner base layer and an adjacent, radially outer functional layer. The base layer includes a resilient matrix material reinforced by embedded fibers, and the functional layer includes a matrix material with a lower fiber content than the base layer.Type: GrantFiled: September 12, 2005Date of Patent: October 30, 2007Assignee: Voith Paper Patent GmbHInventors: Jörg Rheims, Lothar Zimmerman, Eugen Schnyder

Patent number: 7169258Abstract: A device treats a fiber stock suspension with at least one additive, the fiber stock suspension being used for production of at least one of paper and cardboard. The fiber stock suspension includes a suspension medium and a fiber material. The fiber material has fiber surfaces, the fiber surfaces being moistened by the suspension medium. The device includes a fluffer having an inlet for receiving at least one of the fiber stock suspension and the at least one additive. The fluffer is coupled to the inlet, the fluffer being configured for separating the fiber material and enlarging a specific surface of the fiber surfaces.Type: GrantFiled: May 23, 2001Date of Patent: January 30, 2007Assignee: Voith Paper Patent GmbHInventors: Jörg Rheims, Klaus Doelle, Oliver Heise, Werner Witek, Shawn Flanigan, Robert J.

Publication number: 20050257906Abstract: A method and apparatus for treating a web of paper or board applies a functional coating to the web, followed by calendaring. The functional coating is first applied without direct contact between a coating supplier and the web. Next, the web is calendered utilizing a broad nip in a shoe calendar, the shoe calendar having a shoe roller with a rotating outer cover and a squeeze roller. The shoe calendar has a shoe roller exhibiting a rotating outer cover and a squeeze roller interacting with the shoe roller.Type: ApplicationFiled: May 4, 2005Publication date: November 24, 2005Inventors: Jorg Rheims, Ulrich Rothfuss

Patent number: 6881298Abstract: For a process and an apparatus for loading fibers contained in a pulp suspension with calcium carbonate, a calcium oxide and/or a medium containing calcium hydroxide is fed to the pulp suspension, and the so treated pulp suspension is further charged in several reactors with pure carbon dioxide or a medium containing carbon dioxide. The reactors can be connected in series and/or in parallel.Type: GrantFiled: February 19, 2003Date of Patent: April 19, 2005Assignee: Voith Paper Patent GmbHInventors: Jörg Rheims, Klaus Doelle, Oliver Heise, Werner Witek

Patent number: 6537425Abstract: During the chemical process of loading with calcium carbonate fibers contained in a pulp suspension, a medium containing calcium oxide or calcium hydroxide is added to the pulp suspension. This treated pulp suspension is charged in at least one reactor with pure carbon dioxide (or a medium containing carbon dioxide), which, during the progression of the reaction, converts at least a significant portion of the starting materials (calcium oxide and/or calcium hydroxide and carbon dioxide) into the reaction products, calcium carbonate and water. This reaction is accomplished by properly controlling the pulp suspension's pH.Type: GrantFiled: July 11, 2001Date of Patent: March 25, 2003Assignee: Voith Paper Patent GmbHInventors: Jörg Rheims, Klaus Doelle, Oliver Heise, Werner Witek
