A method of manufacturing a fabric seam in a fabric for use as papermachine clothing, the fabric having loops at each of the fabric's transverse ends adapted for interconnection by way of a pintle to make the fabric endless, including the steps of bringing the ends into end-to-end disposition in order to interdigitate the loops, inserting a pintle in the interdigitated loops, heat setting to fix base yarns and the loops of the fabric in place, inserting at least one stuffer yarn, at least a part of which includes a low melt component, into selected void areas in the loops adjacent the pintle, adhering at least one batt layer to the seam by needling, and further heat setting to at least partially melt the stuffer yarn such that it deforms to substantially take on the shape of the void areas at the pintle joint, to bind fibers of the batt needled into the void areas and to bind adjacent yarns of the fabric.

Fabric seams

A paper machine fabric leader includes a leader having a first end, a second end, a first leader face and a second leader face, the first end being connected to a paper machine fabric; and a solid sheet cover attached to the first leader face of the leader. A method for making the paper machine fabric leader is also disclosed.

Paper machine fabric leader

There is provided an industrial fabric comprising a layer of batt of fibres optionally needled to a base cloth, whereby during manufacture of the fabric a dispersion of particulate, polymeric material has been applied to the layer of batt of fibres and thermally activated to provide a discontinuous layer containing a mixture of batt fibres and a polymer-baft fibre matrix.

Composite press felt

A press felt comprises a base fabric, optionally with a batt of fibrous material needled thereto. The base fabric is woven endless, having upper and lower layers of weft yarns and first and second sets of warp yarns. The first set of warp yarns interweaves with at least the upper layer of wefts and the second set of warp yarns interweaves with at least the lower set of wefts. At least some of the first set of warps at least occasionally interweave with the lower wefts and at least some of the second set of warps at least occasionally interweaves with the upper wefts.

Press felt

Paper making machine fabric comprising weft yarns extending in the machine direction (MD) and forming seaming loops at each end of the fabric, cross machine direction (CD) warp yarns being interwoven with the weft yarns, wherein that at least one multifilament warp yarn is inserted so that there is at least one standard warp yarn between the multifilament yarn and the seaming loops on each side of the seam.
