A belt for a machine for the production of a fibrous web, in particular paper or cardboard, the belt including a carrier structure, a first material which forms a first pattern on at least one side of the carrier structure such that a portion of the carrier structure remaining exposed, and a second material which forms a second pattern, the second pattern being applied onto the first pattern, wherein the second pattern is completely disposed within the first pattern and a method for producing same.

Belt for a machine for the production of a fibrous web, particularly paper or cardboard, and method for the production of such a belt

The invention relates to a method for producing a topographical pattern from polymer material on an endless strip with a longitudinal direction and a transverse direction extending perpendicularly thereto, in which method a cylindrical rotary screen is used to apply the polymer material by the screen printing process to a circumferential side of the endless strip to be printed, wherein, when producing the pattern, the rotary screen, rotating repeatedly about its longitudinal axis, rolls on the circumferential side of the endless strip, whereby the pattern is applied to the circumferential side in at least one path running at least once uninterruptedly around the circumferential side in such a way that the beginning and the end of each revolution of the path are arranged along a common straight line, wherein, when rolling, the rotary screen performs N revolutions about its longitudinal axis during each revolution of the path on the circumferential side of the endless strip and N is a positive integer.

Method for producing a pattern on an endless strip

A method for producing a topographical pattern on or in a papermachine fabric. The method for creating the pattern on or in an fabric, includes producing a topographical polymer pattern on or in a papermachine fabric using a rotary screen. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Method for producing topographical pattern on papermachine fabric by rotary screen printing of polymeric material

A press fabric having a plurality of surface pressing plates on a sheet side of the fabric imparts an impression onto a sheet of paper web during a pressing process. The surface pressing plates are preferably resin pressing plates, and form at least one of a random pattern of dots, a predetermined pattern of dots, a grid pattern of dots, a regular grid pattern of lines, an irregular grid pattern of lines a plurality of squiggly lines, a plurality of wavy lines, a plurality of straight lines, words and pictures.

Patterned press fabric

A method for manufacturing a fabric-like clothing, in particular for a machine for producing web material, in particular paper or paperboard, including the measures: a) providing a fabric-like substrate with at least one seam region extending essentially in the substrate transverse direction (CMD); b) applying a coating onto the fabric-like substrate such that the coating extends over at least one seam region; and c) cutting through the coating along at least one seam region.

Method for manufacturing papermachine clothing

A covering for a machine for the production of a fibrous web has, at least in some sections, a two-dimensional structure which is formed by a multiplicity of polymer-based regions which differ from each other at least in part by virtue of a different fraction of filler material and/or by virtue of a different type of filler material.

Paper machine covering

Endless belt for extended nip dewatering presses

A method and apparatus is disclosed for manufacturing papermakers or like fabrics wherein preformed apertured fabric bands are joined together in spaced edge-to-edge disposition in a manner to provide substantial uniformity of construction throughout the fabric width. The invention proposed supporting the bands (11, 12) in spaced parallel disposition on a pinned roller (26) wherein the distribution and configuration of the pins (34) matches the apertures in the bands and creating an infill band in the region between adjacent preformed bands (11, 12) by feeding thermoplastic matrix material to the surface of the pinned roller in said region, causing said matrix material to flow into interstices between the pins and to bond with the material of the preformed bands. Reinforcing yarns (13) will be provided in the region between adjacent preformed bands and extending in a direction parallel to the bands and will be embodied within the matrix material of the joined structure. Transversely extending yarns may be provided on the preformed bands for like encapsulation by the matrix material of the infill band.

Edge jointing of fabrics

An ENP belt for use in the press-section of a papermaking machine is disclosed which comprises a sheet-like body part (11) having integrally formed machine-direction ribs (12) extending outwardly from the surface therefrom, there being reinforcing yarns (16) in register with respective ones of some at least of the said ribs (12) and at least partially located therein. Cross machine direction ribs (15) extending between adjacent machine direction ribs may be provided, if desired.

Extended nip dewatering press belt with reinforced ribs

In order to protect the longitudinal edges of a link belt against damage or undue wear it is proposed to provide an edge guard comprising a multiplicity of guard elements engaged with the coils of the belt, the elements each comprising a body part for disposition adjacent the edge of the belt and a mounting element for engagement with a respective coil. The body part is preferably flexible, and the body parts of adjacent elements may partially overlie one another in providing a reinforcing wear resistant edge to the belt for protecting the ends of the coils.
