  • Patent number: 11293141
    Abstract: A fabric for a web-producing machine, such as a papermaker's machine for producing paper, tissue or board, contains a machine-side and a paper-side. The fabric further contains MD-yarns and CD-yarns interwoven with each other in a predetermined repeat pattern. The MD-yarns 12 have a non-circular cross-section, and a width-to-height aspect ratio of the MD-yarns 12 is greater than 10:1, preferably at least 11:1. Furthermore, a web-producing machine, such as a papermaker's machine for producing paper, tissue or board, contains a fabric of the above described type, where the fabric is preferably applied in a dryer section of the web-producing machine.

  • Patent number: 10179976
    Abstract: An industrial textile for use in a fibrous web forming and/or processing machine has a transversal edge section which can be joined together to render the textile endless. MD-yarns are interwoven with CD-yarns. At least two adjacent MD-yarns form a group, the MD-yarns of each MD-yarn group weaving side-by-side the same weave path with the CD-yarns. Each of the MD-yarn groups has adjacent first and second MD-yarns. The first MD-yarn of a MD-yarn group is non-adjacent the first MD-yarn of an adjacent MD-yarn group and the second MD-yarn of said MD-yarn group is non-adjacent the second MD-yarn of the adjacent MD-yarn group. At each transversal edge section the first MD-yarn of a first MD-yarn group forms a first loop and weaves back into the weave path of the first MD-yarn of a second MD-yarn group. The second MD-yarn group is adjacent the first MD-yarn group.

  • Patent number: 9976254
    Abstract: A seam for joining together the ends of woven fabric to form an endless belt is particularly suitable for joining the ends of woven synthetic dryer fabrics as used in the dryer section of paper making machines and is particularly applicable to joining the ends of those dryer fabrics in at least the machine direction of the fabric. A papermaking fabric comprising a woven fabric body having opposing ends, said fabric body having a system of MD-yarns interwoven with a system of CD yarns. The MD-yarns include first pairs of MD-yarns, second pairs of MD-yarns and third pairs of MD-yarns and the first and the second pairs of MD-yarns form two seam loops, while the third MD-yarns forms the binder. The loops are at identical length to each other over the whole fabric width. Such seam construction reduces marking and increases the seam strength and seam abrasion resistance.

  • Patent number: 9890501
    Abstract: A papermaking dryer fabric has a system of MD yarns interwoven with a system of CMD yarns in a single layer weave. The MD yarns have groups each formed of a plurality of adjacent MD yarns weaving in the group side-by-side the same weave path with the CMD yarns. The dryer fabric is flat woven with seaming loops at the widthwise edges of the fabric to make it endless. At least some of the seaming loops are formed by at least some MD yarns of the groups of MD yarns. The MD yarns forming the groups of MD yarns have a circular cross section and the CMD yarns are ungrouped CMD yarns and at least some of said CMD yarns have a non-circular cross section with a width to height ratio of more than 1. The dryer fabric has an air permeability between 25 cfm and 200 cfm.
