US Classification:

139383A, 139383 AA, 139420 A, 1623582, 162900

Abstract:

A through-air dryer (TAD) fabric formed by interweaving of a warp yarn system with a weft yarn system. The TAD fabric has a paper side with a contact area between 20% and 30%. The warp yarn system includes flat warp yarns and/or the weft yarn system includes flat weft yarns which have not been subjected to a sanding process after weaving of the fabric and which have an aspect ratio of 1. 15:1 to 1. 35:1.

Inventors:

Lippi Alves Fernandes - Overijssel, NL
Sanjay Patel - Summerville SC, US

Assignee:

Voith Paper Patent GmbH - Heidenheim

International Classification:

F26B 11/02

US Classification:

34115, 442218, 162361

Abstract:

A through air dryer (TAD) fabric having a composite configuration whereby side fabric portions made of a more resistant material are woven to the main body portion of the fabric. Side fabric portions that are not protected from the paper web, and therefore exposed to harsher environmental conditions than the portion of the fabric covered by the paper web, deteriorate faster. By replacing the side portions that are exposed to harsher environment with more resistant material, the TAD fabric will last longer.

Abstract:

A method of joining two ends of a fabric for use in a paper machine, carried out using a joining assembly, includes the steps of: placing a first end of the fabric on a first portion of a pin plate, the pins in the first portion of the pin plate extending into the first end; placing a second end of the fabric on a second portion of the pin plate such that the first end and the second end are in close proximity to each other in a join area, the pins in the second portion of the pin plate extending into the second end; and joining the first end and the second end in the join area. The method results in a perforated (and therefore permeable) join area.

International Classification:

D02G 3/02

US Classification:

57235

Abstract:

A pintle for joining the ends of a pin-seamable paper machine fabric wherein the pintle comprises a braided sheath of an ultra high molecular weight polyethylene yarn and optionally is filled with polyamide monofilament or polyethylene yarn. The pintle is configured to substantially fill the voids in the fabric loops when inserted so that a smoother seam is achieved that significantly reduces marks on the resultant paper.
