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.

A papermaking felt with two or more plain weave base fabrics that can be bonded to each other. The joint portions do not open when a batt fiber layer is attached or when the felt is used. The papermaking felt can be made from an MD yarn material in the felt running direction (MD direction) and a CD yarn material in the felt cross-direction (CD direction), including a combination with two or more base fabrics directly overlapped with each other, which have a joint portion wherein the MD direction end portions are joined which include a first MD direction end portion and a second MD direction end portion wherein, with regard to the base fabrics having all included joint portions. The equations (1) and (2) below are satisfied when the maximum distance in the MD direction between the joint portions of the base fabrics is x (cm) and the minimum distance thereof is y (cm): x≤750 (1); and 51≤y (2).

The object of the present invention is to provide a papermaking felt having good productivity and a laminated structure using 2 or more plain weave base fabrics that can be bonded to each other, wherein the joint portions do not open when a batt fiber layer is attached or when the felt is used, and to provide a method for producing the same.

This is achieved by a papermaking felt made from an MD yarn material in the felt running direction (MD direction) and a CD yarn material in the felt cross-direction (CD direction), comprising a combination in which 2 or more base fabrics are directly overlapped with each other, which have a joint portion in which the MD direction end portions are joined which comprise a 1st MD direction end portion and a 2nd MD direction end portion wherein, with regard to the base fabrics having all included joint portions, the equations (1) and (2) hereinafter are satisfied when the maximum distance in the MD direction between the joint portions of the base fabrics is x (cm) and the minimum distance thereof is y (cm).

A seamed press felt formed from a base fabric having a CD width and an MD length with two opposing MD ends that are joined to form a continuous belt. MD oriented yarns form uniform loops at the two opposing MD ends that are interdigitated to define a pintle channel extending across the CD width. CD oriented yarns are connected to the MD oriented yarns, in a woven or non-woven construction. Loop open spaces are located within the loops on each of the two opposing MD ends in a seam region, with the loop open spaces being defined between a last one of the CD yarns at each of the two opposing MD ends and the pintle channel. At least one CD monofilament support yarn is located in the loop open spaces on each of the two opposing MD ends. The at least one CD monofilament support yarn has a diameter that is at least 1.6 times a diameter of the CD oriented yarns. A pintle extends through the pintle channel to form a seam.

A covering is particularly suited for use in a machine for producing and/or finishing a paper, cardboard, tissue or pulp web. The covering has a basic structure formed as a part of a flat woven material, which flat woven material is designed as a woven material by interlacing warp threads and weft threads. The portion of the flat woven material has a plurality of sections that are formed integrally with each other, with at least one property of one of the sections differing from the respective property of at least one adjacent section.

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.
