In one embodiment, a pintle insertion tool is disclosed. The pintle insertion tool includes a housing, and a drive assembly supported by the housing. The drive assembly includes a controller connected to a power supply and configured to drive at least one motor. The drive assembly includes a first roller and a second roller defining at least a portion of a channel therebetween. The at least one motor is configured to rotate the first roller and the second roller in both a forward direction and a reverse direction. The channel is adapted to receive a pintle lead wire such that the pintle lead wire is driven by the first roller and the second roller through interdigitated seam loops on opposing ends of a textile sheet so that a pintle can be pushed into position to complete a seam.

The invention relates to a base fabric of a press felt. The base fabric comprises end regions which are provided with seam loops (4). The seam loops are slanted. Further, the invention relates to a press felt and a method of forming the same.

A basic structure of a clothing for a machine for producing or processing a fibrous web, in particular a paper, cardboard or tissue web. The basic structure has at least a first flat fabric of fabric type A and a second flat fabric of fabric type B, and, furthermore, two loop elements. The loop elements are formed in each case from a flat fabric piece which has a first portion of fabric type A and a second portion of fabric type B. The first portion is laid down on the second portion in such a way that the folding point is formed at a spacing of less than 5 cm, in particular less than 1 cm, from the changeover position between the fabric type A and the fabric type B. The first and the second flat fabric are arranged above one another, and the two loop elements are arranged in each case at a face-side, front end.

A fabric for a paper or pulp technology has a longitudinal direction (MD) and a cross direction (CMD), and a first surface (FS) and a second surface (SS) in a fabric thickness direction (TD). The fabric (1) extends in the cross direction (CMD) from a first edge (FG) to a second edge (SG). The fabric (1) has an adaptable medium comprising at least one sensor. The adaptable medium is a deformable structure that adapts to the fabric where it is inserted and may be a string or a sheet configured to detect temperature, temperature profile, wear, volatile organic compounds (VOC), humidity, pH, microbial level, organic and inorganic material content, dirt content, flow rate and flow velocity field, or pressure in a nip. The invention also relates to a method for manufacturing a fabric for a paper or pulp technology.

The present invention is directed to forming fabrics. The forming fabrics may include a series of repeat units. Each of the repeat units may include a set of binding warp yarns including a first set of binding warp yarns and a second set of binding warp yarns, wherein a binding warp yarn from the first set is paired with a binding warp yarn from the second set; a set of spring warp yarns, wherein each spring warp yarn is between a first pair of binding warp yarns and a second pair of binding warp yarns; a set of top weft yarns including odd and even top weft yarns, wherein the top weft yarns interweave with the binding warp yarns and the spring warp yarns to form a top fabric layer, wherein the spring warp yarns interweave only with the top weft yarns; a set of bottom weft yarns; and a set of bottom warp yarns, the bottom warp yarns interwoven with the bottom weft yarns to form a bottom fabric layer. The binding warp yarns from the first and second set and the spring warp yarns interweave with the top weft yarns to relatively form a plain weave pattern in defined zones such that (a) the first set of binding warp yarns only pass over even top weft yarns; (b) the second set of binding warp yarns only pass over odd top weft yarns; (c) the first binding warp yarn in the pair is offset from the second binding warp yarn in the pair by at least three top weft yarns to create an overlap in the warp path of the pair of binding warp yarns; and (d) each spring warp yarn passes over even and odd top weft yarns. The binding warp yarns from the first and second set and the bottom warp yarn interweave with the bottom weft yarns.

A fabric clothing, in particular a press felt, for use in a machine for producing a fibrous web, contains a woven fabric strip having interwoven longitudinal threads and cross threads, as well as having a first and a second longitudinal end. The two longitudinal ends of the woven fabric strip are connected to one another in a connection zone. Provision is made that the two longitudinal ends are welded to one another by a transmission welding, in particular by a laser transmission welding.
