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.

An industrial two-layered fabric includes a front side fabric with warps and wefts and a back side fabric with warps and wefts. The front and back side fabrics are bound by binding warps. A first pair of warps consists of the front side warp and back side warp. A second pair of warps consists of two binding warps. A mutually complementary structure presents where one of the two binding warps forms consecutive knuckles on the front surface while another one of the two binding warps does not emerge on the front surface side, and where the another one of the two binding warps forms consecutive knuckles on the front surface whereas the one of the two binding warps does not emerge on the front surface side. A back side warp and an adjacent binding warp form knuckles below a one back side weft and another one back side weft.

Apparatus, methods, and fabrics for dewatering a nascent paper web, carried in a web sandwich, in a dewatering section of a papermaking machine. Water is driven from the web by a combination of mechanical pressure and compressed air, both typically applied in a nip. The mechanical pressure and air pressure can be applied in the same nip, or in separate nips, where the mechanical pressure is applied upstream, in the papermaking machine, from the air pressure application. The mechanical pressure can be lower than pressures used in conventional press sections of known papermaking machines. Air pressure is that pressure which can be contained in a seal section between the web sandwich and the structure supplying the air. Fabrics supporting the nascent paper web through the air dewatering station have limited lateral air flow under compressed air conditions, whereby air flows generally perpendicularly through the web being dewatered.

A clothing for paper or pulp dewatering machines comprising monofilaments comprising a partially aromatic polyamide. A machine-side fabric layer is provided, and at least the machine-side fabric layer comprises monofilaments with a partially aromatic polyamide. The clothing comprises or is formed by longitudinal threads extending in a running direction and transverse threads extending transversely to the longitudinal threads, and at least some of the transverse filaments are monofilaments with a partially aromatic polyamide.

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 papermaker's fabric includes a series of repeat units, wherein each of the repeat units includes: a set of top machine direction MD yarns having a first diameter; a set of bottom MD yarns having a second diameter larger than the first diameter; a set of auxiliary bottom MD yarns having the first diameter; a set of top cross machine direction CMD yarns interwoven with the top MD yarns to form a top fabric layer; a set of bottom CMD yarns interwoven with the bottom MD yarns and the auxiliary bottom MD yarns to form a bottom fabric layer; and a set of stitching yarns arranged in pairs, wherein at least one of the stitching yarns of the pair interweaves with the top and bottom fabric layers.

A shoe press belt (10) for a shoe press has an inner surface (11), an outer surface (12), an elastomer body and a support structure (20, 21, 22, 23) for the elastomer body. A plurality of parallel dewatering grooves (50, 50a, 50b) are on the outer surface (12) of the shoe press belt (10), with a ridges (53) provided between two adjacent dewatering grooves (50a, 50b). The dewatering grooves (50, 50a, 50b) have a first wall (60), a second wall (70), and a bottom (80) therebetween. At least the first wall (60) of the dewatering groove (50, 50a, 50b) has a plurality of parallel auxiliary grooves (100, 100a, 100b). A paper, board or pulp drying machine has said shoe press belt (10). A method for installing the shoe press belt (10) is provided.

The invention relates to an industrial fabric, such as a texturing belt, used to create three-dimensional structures in a product produced thereon, e.g., in the papermaking field, such as for fiber products, and in nonwoven processes. The invention concerns a texturing belt that can impart an endless variety of complex patterns utilizing discretization, such as, wherein individual subunits that comprise a pattern element are not connected, and therefore do not act as a stressed member of the texturing belt.

Web material structuring belts that impart structure to a web material during a web material structuring operation and/or structured web material forming operation, method for making same and methods for using same to make structured web materials, for example structured fibrous structures, such as structured sanitary tissue products such as structured toilet tissue, structured paper towels and structured facial tissue are provided.
