  • Patent number: 7032625
    Abstract: A multi-layer on-machine-seamable press fabric having a single or double layer weave over the seam loops where the warp ends are not normally woven with CD yarns. The CD yarns woven into the layer(s) over the seam loops provide the fabric with substantially similar characteristics—including caliper and water permeability—in the seam area as in the remainder of the fabric. Hence, the press fabric provides a solution to the problem of non-uniformity in the seam area, which often results in sheet marking.

  • Publication number: 20050252566
    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.

  • Publication number: 20040109960
    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. A pintle or installation cable is positioned between each set of connectors to form a seam. The pair of connectors for each set of seam loops comprises different lengths in the MD direction such that the pintle or installation cables on adjacent layers are offset in the MD direction.

  • Patent number: 6302155
    Abstract: An on-machine-seamable press fabric for the press section of a paper machine includes a multi-layered integrally woven base fabric having two systems of machine-direction yarns forming seaming loops along each of its two widthwise edges. A seaming spiral is attached to the seaming loops in both rows at each of the two widthwide edges. The two seaming spirals are used to join the press fabric into endless form during installation on the press section of a paper machine.

  • Patent number: 6265048
    Abstract: The invention relates to a laminated clothing for a papermaking or cellulose manufacturing machine, as well as a method and a blank for manufacturing thereof. The clothing comprises two laminated layers (O, I), each having an inclined direction-defined thread system, the thread systems being inclined relative to the machine direction of the clothing and relative to each other. The two layers (O, I) constitute an upper and an inner part, respectively, of an endless band (40), which is so flattened that two edge folds (48, 50) are formed transversely of the machine direction, and which is then doubled with the edge folds (48, 50) coupled together. As a result, the band comprises a direction-defined thread system which is inclined relative to the machine direction and which, owing to the flattening and doubling of the band, forms the thread systems, inclined relative to each other, of the first and the second layer (O, I).

  • Patent number: 5531251
    Abstract: A method of manufacturing a double-layered fabric designed for use in a papermaking, cellulose or board manufacturing machine by a round-weaving technique involves the weaving of an endless weft thread with a plurality of warp threads. Seam loops are formed at the two ends of the fabric by weaving the endless weft thread around a seam thread during the weaving process. In this process, the plurality of warp threads are on one side of the seam thread. The fabric has a first side for supporting fibrous web material to be dewatered and an underside, and the endless weft thread is alternatively disposed on the first side and on the underside of the fabric with each pass around the seam thread. The method includes the improvement wherein the endless weft thread is woven with at least one extra warp thread adjacent to the seam thread when the endless weft thread is on the first side of the double-layered fabric.

  • Patent number: 5476123
    Abstract: A woven fabric, such as a base fabric for a press felt, which is designed for a papermaking machine or the like has along each one of two end edges a plurality of seam loops to be included in a loop seam to form an endless woven fabric. The fabric is characterized in that there is provided, at least at one of the end edges, at least one string of material, preferably in the form of one or more extra yarn threads, extended substantially parallel to the above-mentioned one end edge adjacent the regular thread system of the fabric. The extra yarn thread or threads are woven to only such portions of the seam loops as are facing a first side of the fabric, preferably the paper side thereof. In this manner, there is formed in the seam zone a type of extension of the regular thread system of the fabric, whereby the loop seam is conformed to the rest of the fabric to avoid markings in a paper web at the loop seam.
