Patent number: 11505897Abstract: An industrial textile (6) for manufacturing a fibrous web has first machine direction yarns (1) on the front side (7) which bind to first cross-machine direction yarns (4) in a first pattern, while second machine direction yarns (2) on the back side bind to second cross-machine direction yarns (5) in a second pattern. Third machine direction yarns (3) bind to the first cross-machine direction yarns (4) and the second cross-machine direction yarns (5) in a third pattern. The third pattern has at least one interlacing point (71) on the front side where one of the third machine direction yarns (3) passes over one of the first cross-machine direction yarns (4) and at least one interlacing point (72) on the back side (8) where the same third machine direction yarn (3) passes under one of the second cross-machine direction yarns (5).Type: GrantFiled: June 3, 2021Date of Patent: November 22, 2022Assignee: VALMET TECHNOLOGIES OYInventors: Hannu Martikainen, Tania Rautio, Mari Seppänen, Seppo Taipale

Publication number: 20180355555Abstract: The invention relates to a paper machine fabric that consists of two layers, a paper-side layer and a wear-side layer. The paper-side layer consists of the top warps (1) and at least the binding top wefts (2), which have been adjusted to form a part of the paper-side surface, and the wear-side layer consists of the bottom warps (3) and bottom wefts (4). The binding top wefts (2) have been adjusted to bind the paper-side layer and the wear-side layer together. Each binding top weft (2) is adjusted so that it forms a continuous independent yarn path.Type: ApplicationFiled: December 2, 2016Publication date: December 13, 2018Inventors: Seppo TAIPALE, Mari SEPPANEN, Hannu MARTIKAINEN, Tania RAUTIO

Patent number: 7803252Abstract: The invention relates to a flexible and porous fabric structure comprising a support structure (1) and a coating material for use in a paper machine. The coating material (2) is arranged solely on the surface of the support structure (1) at a predefined location(s) so that the coating material (2) does not substantially alter the permeability properties of the support structure (1). The invention also relates to a method for manufacturing a fabric structure.Type: GrantFiled: September 12, 2005Date of Patent: September 28, 2010Assignee: Tamfelt PMC OyInventors: Hannu Martikainen, Pekka Kortelainen, Tania Rautio, Mari Seppanen, Ali Harlin, Tuula Wilenius-Jaakonaho

Patent number: 7507679Abstract: A paper machine fabric comprising at least two machine direction yarn systems, which are bound together by means of a binding yarn system. The layer of the machine side is formed of a warp system and a binding yarn system. The binding yarn system comprises a binding yarn, binding yarns or a pair of binding yarns. The binding yarn, the binding yarns or the pair of binding yarns is/are bound to more than one bottom warps at the point where the binding yarn binds the top and bottom warps together.Type: GrantFiled: June 29, 2004Date of Patent: March 24, 2009Assignee: Tamfelt OYJ ABPInventors: Seppo Taipale, Terttu Turpeinen, Tania Rautio, Pekka Kortelainen

Patent number: 7001489Abstract: A paper machine fabric comprising at least two separate layers formed using at least two separate yarn systems: one constituting the paper side and comprising machine direction and cross machine direction yarns and the other constituting the machine side and comprising machine direction and cross machine direction yarns, the yarn systems being arranged to form independent structures in both directions of the fabric. The structures are bound together with binder yarns, a binder yarn being arranged to form part of the weave of a layer on the paper side surface and arranged to be interwoven with a layer of the machine side by being interwoven under at least one yarn in the machine side layer. The number of machine direction yarns in the layer constituting the machine side is larger than the number of machine direction yarns in the layer constituting the paper side.Type: GrantFiled: April 10, 2003Date of Patent: February 21, 2006Assignee: Tamfelt OYJ ABPInventors: Seppo Taipale, Terttu Turpeinen, Tania Rautio, Pekka Kortelainen
