  • Patent number: 7811627
    Abstract: A papermaking fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter in the papermaking system. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

  • Patent number: 7455078
    Abstract: A method of making a seam for an endless woven multilayer papermakers fabric such as a press felt base fabric, comprises selecting a repeating weave pattern so as to provide during weaving a body portion woven as a double layer, and a shed change for the warp yarns adjacent to the warp yarns of the body portion to provide a first and second seaming portion. In each seaming portion the warp yarns are separated into an upper group and a lower group such that the weft yarn interweaves separately with each group to form a distinct upper and lower layer. A forming wire is provided at the vertically aligned lateral edges of the fabric, and the weft yarn in sequence interweaves with the upper group of warp yarns to provide the upper layer, forms a seaming loop about the forming wire and interweaves with the lower group of warp yarns to provide the lower layer. The method and a fabric made by the method provide improved uniformity of the seaming loops and reduced sheet marking in the seam area.

  • Patent number: 7406985
    Abstract: A papermaking screen, especially for the sheet forming zone, has one paper side and one machine side with a first type of transverse yarns of the paper side and a second type of transverse yarns (25 to 40) of the machine side. The transverse yarns are woven with at least one type of longitudinal yarns (41 to 56). The longitudinal yarns (41 to 56) on the machine side within the machine-side pattern repeat bind two respective transverse yarns of the second type (25, 28; 31, 34; 37, 40). The division of the intersections for the longitudinal yarns is then improved, so that marks in the paper to be produced are prevented to the greatest extent possible.

  • Patent number: 7381308
    Abstract: A method of seaming an on-machine-seamable multiaxial papermaker's fabric to prevent yarn migration. The multiaxial fabric is in the form of an endless loop flattened into two layers along fold lines. CD yarns are removed from the folds to create extended ravel areas. This leaves the MD yarns unbound in the ravel areas. Seam loops are then formed from the unbound MD yarns at the folds. CD materials (e.g. continuous CD yarns) are affixed to (rewoven into) the fabric along the edges of the ravel area at each fold. The affixed CD materials bind the CD yarn tails along the edges of the ravel areas to prevent migration of CD yarn tails into the seam area.

  • Patent number: 7374639
    Abstract: A papermaking belt having a reinforcing structure and a pattern layer is disclosed. The reinforcing layer has a first layer of interwoven machine direction yarns and cross-machine direction yarns. The machine direction and cross-machine direction yarns of the first layer are interwoven in a weave. The pattern layer extends outwardly from and into the first layer. The pattern layer provides a web contacting surface facing outwardly from the first layer. The pattern layer further has at least one region having an amorphous pattern of elongate two-dimensional geometrical shapes having a longitudinal axis having an angle relative to either of the machine direction or the cross-machine direction. The amorphous pattern of two-dimensional geometrical shapes has a statically controlled degree of randomness.

  • Patent number: 7357972
    Abstract: A liquid-permeable support for a paper machine clothing that is usable in the press section of a paper machine includes a support having at least two plies that brace against one another via discrete bracing elements. At the points where the plies brace against one another, there is applied on one or both sides an elastic coating which is embodied elastically in such a way that the spacing of the plies under pressure loading is decreased by elastic compression of the coating. Upon pressure relief the spacing is increased again by elastic recovery of the coating.

  • Patent number: 7306014
    Abstract: In a lower surface side layer of an industrial two-layer fabric, warps are formed by sequentially arranging a repeating design unit, in which one warp passes over six successive lower surface side wefts, passes under one lower surface side weft, passes over two lower surface side wefts, and passes under one lower surface side weft while shifting the design by three lower surface side wefts. Two adjacent lower surface side warps simultaneously weave therein, from the lower surface side, one lower surface side weft, whereby the lower surface side weft passes over two lower surface side warps and then passes under eight lower surface side warps to form a weft long crimp corresponding to eight lower surface side warps on the lower surface side surface.
