  • Patent number: 8980062
    Abstract: An industrial fabric, belt or sleeve and a method of making the fabric, belt or sleeve are disclosed. The industrial fabric, belt or sleeve is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, around two rolls in a side-to-side manner in which a gap between adjacent edges is formed. A second material, for example a gap filler material, is placed between the adjacent edges, and the adjoining edges are joined by melting the filler material, strips of polymeric material, or both. The gap filler material can have a specific cross-sectional shape corresponding to the gap.

  • 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.

    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 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. A thin porous material is sewn to the fabric at each fold. The porous material binds the CD yarns along the edges of the ravel areas while allowing passage of the seam loops through the material. The laminate prevents migration of CD yarn tails into the seam area.

    Abstract: An industrial process fabric and a method for manufacturing such a fabric. The fabric is made of material and is endless, or made endless with a seam, in the machine direction of a machine on which it is used. The fabric comprises at least one layer composed of a spirally-wound strip made of material and having a width which is smaller than the width of the final fabric. The longitudinal axis of the spirally-wound strip of material makes an angle with the machine direction of the fabric.

  • Patent number: 7141144
    Abstract: A multi-layer woven papermaker's fabric having at least two sets of seam loops. Longer and a shorter seam attachment mechanisms are used to connect the bottom and top layer seam loops. The longer attachment mechanism in the top layer being over the shorter attachment mechanism in the bottom layer, and vice versa.

  • Patent number: 7029555
    Abstract: A diagonally joined cylindrical fabric in the form of a cylindrical endless fabric is obtained by shifting ends of facing wefts of a non-endless fabric leftward or rightward and joining together the ends of the wefts to thereby form a joining portion inclined relative to an axis of a cylinder. The cylindrical fabric comprises a weave pattern in which warp passes over continuous two or more wefts, then passes under a less number of wefts, the joining portion at ends of the fabric formed into an endless cylindrical shape is inclined relative to the axis at 25° to 5°. The surface of the cylindrical fabric is formed with crimps that are longer in a face length direction than in a circumferential direction.

  • Patent number: RE39709
    Abstract: A multilayer papermaker's press felt fabric comprising in combination a woven first fabric layer, typically a double layer fabric, has a cross machine direction pin seam. A second fabric layer is located on the paper side face of the first fabric layer, and a layer of needled batt is applied to the paper side face of the second layer binding the layers together. A flap comprising a short length of the second fabric layer with attached batt overlays the pin seam area in the first layer. The second layer comprises a plurality of relatively narrow strips, which are located with a lateral edge at a first cant angle of from more than 1° to less than 20° to the machine direction. A third layer, similar to the second layer, can be included on the machine side of the first layer; the strip widths, the cant angles, and the direction of the cant angle relative to the machine direction for each of the two strips need not be the same. The fabric is assembled using a spiral winding technique.
