Patent number: 11712756Abstract: A paper machine clothing has a plurality of through-channels formed in a usable region. The through-channels extend through the substrate to connect the upper and lower sides. The through-channels are non-cylindrical with a cross-sectional area becoming smaller along a thickness direction of the substrate from the upper side to a middle region of the substrate. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels, wherein the upper rims of both neighboring through-channels have at least three common local maxima, including two outer common local maxima and one intermediate common local maximum that is located between the two outer common local maxima. There is also described a method of producing such a paper machine clothing.Type: GrantFiled: March 2, 2022Date of Patent: August 1, 2023Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Reinhard Holl, Jens Kallenberg, Michael Straub, Cedric Fitzer

Patent number: 11655591Abstract: A substrate of a paper machine clothing has a usable region formed with through-channels that are non-cylindrical with a cross-sectional area becoming smaller from an upper side to a middle region of the substrate. An upper rim of at least one of the through-channels directly contacts an upper rim of at least one neighboring through-channel and the upper rims have common local maximum. A sectional plane parallel to the thickness direction of the substrate defines an intersecting line with a sidewall of a neighboring through-channel. The intersecting line has a convexly shaped first portion, a concavely shaped second portion, and a third portion that is again convexly shaped going from the at least one common local maximum toward the middle region of the substrate. There is also described a method of producing such a paper machine clothing.Type: GrantFiled: December 11, 2020Date of Patent: May 23, 2023Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Christian Iniotakis, Reinhard Holl, Jens Kallenberg, Michael Straub, Cedric Fitzer

Patent number: 11525213Abstract: A method for producing an edge protector on a clothing for a machine producing or finishing a fibrous, paper, cardboard or tissue web, includes providing a clothing formed substantially from a woven fabric with crossing weft and warp threads and opposite side edges, applying a film strip onto a surface of one side edge and, immediately before bringing the film strip into contact with the clothing, surfaces of the film strip and the clothing facing each other are heated to slightly melt the surfaces. A pressing force exerted on the film strip applied to the surface of one of the side edges, results in the film strip penetrating at least partially into the woven fabric. That side edge of the clothing with the film strip is cooled, resulting in a stable, particularly integrally joined and form-locking connection between the film strip and the side edge of the clothing.Type: GrantFiled: December 9, 2019Date of Patent: December 13, 2022Assignee: VOITH PATENT GMBHInventors: Uwe Koeckritz, Jens Kallenberg

Patent number: 11332854Abstract: A clothing, in particular a drying wire, for a machine for producing a fibrous web, such as a paper or cardboard web, is a planar textile structure from yarns which intersect in a machine direction and in a cross-machine direction. The planar structure has two edges oriented in the machine direction and two edges oriented in the cross-machine direction. The clothing is joinable along the edges oriented in the cross-machine direction in the machine so as to form an endless belt. The clothing is only calendered by introducing energy in peripheral regions which extend along the edges oriented in the machine direction and/or along the edges oriented in the machine cross direction, on account of which in the peripheral regions the MD yarns are welded to the CMD yarns, and the thickness and/or permeability of the clothing are/is reduced.Type: GrantFiled: July 17, 2014Date of Patent: May 17, 2022Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Juergen Abraham, Wan Zeti Zafina Wan Ahmad Nathri

Patent number: 11085149Abstract: A clothing for a machine for producing fiber cement components includes a basic fabric having MD yarns and CD yarns. At least some of the MD yarns are formed from first multifilaments of a first material and second multifilaments twisted therewith of a second material. The first material has a higher tensile strength and a higher melting temperature than the second material. The MD yarns are heat-treated at a temperature between the melting temperature of the second material and the melting temperature of the first material, so that the at least partially melted second material forms a matrix after cooling, in which the first multifilaments of the first material are embedded. A method for producing the clothing is also provided.Type: GrantFiled: May 21, 2019Date of Patent: August 10, 2021Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Bob Crook

Publication number: 20210054565Abstract: A method for producing a base structure of a clothing for use in a machine producing and/or processing a fiber web. The clothing base structure is a laminate formed of at least two layers and the layers are formed substantially from polymer material. The method includes the following steps: locally melting the polymer material of the two layers by the action of radiation from a radiation source and pressing the polymer material of the two layers onto each other. The polymer material of the two layers is thereby guided into a press nip formed by two press rolls, forming an inlet gap, and the radiation is directed into the inlet gap.Type: ApplicationFiled: January 18, 2019Publication date: February 25, 2021Applicant: Voith Patent GmbHInventors: Uwe KOECKRITZ, Jens KALLENBERG, Michael STRAUB, Cedric FITZER, Reinhard HOLL
