Patent number: 11072889Abstract: A covering is particularly suited for use in a machine for producing and/or finishing a paper, cardboard, tissue or pulp web. The covering has a basic structure formed as a part of a flat woven material, which flat woven material is designed as a woven material by interlacing warp threads and weft threads. The portion of the flat woven material has a plurality of sections that are formed integrally with each other, with at least one property of one of the sections differing from the respective property of at least one adjacent section.Type: GrantFiled: May 30, 2017Date of Patent: July 27, 2021Assignee: Voith Patent GmbHInventors: Johan Malmquist, Hans-Joergen Johansson

Patent number: 9957666Abstract: A clothing, in particular for use in a press section of a machine for manufacturing a fibrous web, such as a paper, cardboard, or tissue web, includes a base structure and at least one staple-fiber layer which is disposed on the base structure and is connected thereto. The clothing is assembled from a plurality of strips which are provided in the form of planar formations having a proportion of the base structure and a proportion of the at least one staple-fiber layer. Two mutually opposite edges of the strips have seam loops which are each connected to seam loops of the edges of adjacent strips. The edges having the seam loops are oriented in a cross-machine direction of the clothing. A method for manufacturing a clothing is also provided.Type: GrantFiled: May 12, 2014Date of Patent: May 1, 2018Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Hubert Walkenhaus, Johan Einarsson, Johan Malmquist

Patent number: 9938665Abstract: A clothing for use in machines for producing a fiber web such as a paper, cardboard, tissue or nonwoven web, in particular a press felt, has a load-absorbing main structure and at least one liquid-absorbing and/or liquid-storing structure arranged on and/or in the load-absorbing main structure. The liquid-absorbing and/or liquid-storing structure is a sponge cloth-like porous structure made of regenerated cellulose, viscose or a mixture thereof.Type: GrantFiled: July 22, 2014Date of Patent: April 10, 2018Assignee: Voith Patent GmbHInventors: Johan Malmquist, Kjell Karlsson, Conny Andersson

Patent number: 9765481Abstract: A fabric, in particular a press felt, is provided for use in a press section of a machine for producing a fiber web such as a paper, cardboard, or tissue web. The fabric is formed of multiple strips which are arranged adjacent one another and extend substantially parallel to one another in a machine direction. The strips together form a width of the fabric in the machine transverse direction. Each strip is designed as a double-layered sheet material. Strips arranged adjacently in respective pairs are connected by way of a connecting strip. A part of the width of each of the connecting strips extends in the machine transverse direction into the two adjacent strips. The strips are connected to the connecting strips.Type: GrantFiled: July 25, 2014Date of Patent: September 19, 2017Assignee: Voith Patent GmbHInventors: Johan Malmquist, Kjell Karlsson, Conny Andersson
