Patent number: 7008512Abstract: A papermaker's fabric, usable in the forming section of a paper machine, has three layers of cross-machine-direction (CD) wefts. The forming layer wefts are grouped into pairs. This twinning of the top-layer wefts results in non-equal spacing in the forming layer. This spacing imparts a desired non-uniformity in the web-supporting surface, thereby reducing the fabric diagonal problem. One of the top-layer wefts in each pair is vertically stacked with the middle and wear side layer wefts. The other top-layer wefts in each pair are unstacked. This alignment increases the drainage properties of the fabric. The middle layer wefts provide extra stability in the CD.Type: GrantFiled: November 21, 2002Date of Patent: March 7, 2006Assignee: Albany International Corp.Inventors: David S. Rougvie, Jeffrey Joseph Collegnon, John LaFond

Patent number: 7005043Abstract: A method of manufacturing and a papermaker's or industrial fabric, such as a dryer fabric for the dryer section of a paper machine, includes the application of a polymeric resin material onto preselected locations on the backside of a base substrate using a piezojet array which deposits the polymeric resin material in droplets having an average diameter of 10? (10 microns) or more to build up discrete, discontinuous deposits of the polymeric resin material having a height of about 0.5 mm at the preselected locations. The preselected locations may be the knuckles formed by the interweaving of the yarns making up the fabric. The purpose of the deposits is to separate the backside of the dryer fabric from a surface, such as that of a dryer cylinder or turning roll, to enable air trapped between the dryer fabric and the surface to escape in lengthwise and crosswise directions parallel to the surface, instead of being forced through the fabric, possibly causing “drop off”.Type: GrantFiled: December 31, 2002Date of Patent: February 28, 2006Assignee: Albany International Corp.Inventors: Mary M. Toney, Maurice Paquin

The spiral wound MD layer can also be mated to another MD layer spiraled in the opposite direction and in one embodiment further mated to a CD layer. The fabric is preferably produced so that its neutral line is oriented toward the paper side of the fabric so that the paper sheet will stretch less than when typical dryer fabrics are used to turn the paper sheet and fabric around the dryer cylinders.Type: GrantFiled: June 19, 2003Date of Patent: January 24, 2006Assignee: Albany International Corp.Inventor: Robert A.

Patent number: 6920902Abstract: A fabric having top and bottom layers, with each layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven together. The fabric includes pairs of binder yarns that bind together the top and bottom layers. The binder pairs are interwoven so as to be an integral part of the first layer and contribute to a structure thereof. The binder pairs are a non-integral part of the second layer and do not contribute to a structure thereof. During a repeat pattern, at least one of the two binder yarns of a binder pair is integrally woven with the yarns of the first layer and passes over outer surfaces of two non-consecutive yarns in the second layer. As a result, a “double knuckle” binding structure may be formed which improves integrity of the resulting composite fabric by reducing the length of the binder yarn path through the fabric.Type: GrantFiled: April 10, 2003Date of Patent: July 26, 2005Assignee: Albany International Corp.Inventors: Brian G.

Patent number: 6592714Abstract: The invention relates to a paper machine clothing, notably an air-dry clothing (TAD clothing), in the form of a woven having a weaving design. According to the invention the relative depth of machine clothing cups which are open towards the contact surface of the paper is 20% or more, said relative cup depth being the quotient of the difference between the measurement height for which the bearing percentage is 30% and the measurement for which the bearing percentage is 60%, on the one hand, and the sum of the diameters of a warp thread and a weft, on the other hand. The measurement height “0” is the outer limit of the paper machine clothing on the paper contact surface, the bearing percentage is the projected sectional area of the threads of the woven at a given measurement height in relation to the measurement surface, the section areas being parallel to the surface of the clothing.Type: GrantFiled: October 4, 2001Date of Patent: July 15, 2003Assignee: SCA Hygiene Products GmbHInventor: Hans-Jürgen Lamb

Patent number: 6569290Abstract: A bi-component link for making a modular papermaking fabric has a link base component capable of interconnecting to at least one other link and a surface plate component attached to the link base forming a paper support surface. Each component is made through molding techniques to have predetermined characteristics such as open area, permeability, surface finish, etc. The surface plate component is attached to the link base component for combined effect on fabric characteristics. A papermaking fabric is constructed from a plurality of interconnected bi-component links and has predetermined permeability established by the combination of a pattern of open and contact areas on each component of each link.Type: GrantFiled: February 19, 2002Date of Patent: May 27, 2003Assignee: AstenJohnson, Inc.Inventor: C. Barry Johnson

Publication number: 20030085011Abstract: The present invention is a method of making a tissue product. An aqueous suspension of papermaking fibers is deposited onto a forming fabric thereby forming a wet tissue web. The wet tissue web is transferred to a woven sculpted fabric having a tissue contacting surface. The tissue contacting surface includes at least a first group of strands and a second group of strands wherein the first group of strands extend in a first direction and the second group of strands extend in a second direction.Type: ApplicationFiled: November 2, 2001Publication date: May 8, 2003Inventors: Mark Alan Burazin, Kai F. Chiu, Jeffrey Dean Lindsay

Publication number: 20030085010Abstract: The present invention is a method of making a tissue product. An aqueous suspension of papermaking fibers is deposited onto a forming fabric thereby forming a wet tissue web. The wet tissue web is transferred to a sculpted fabric having a tissue machine contacting side and a tissue contacting side. The tissue contacting side includes an upper porous member comprising a base with nonwoven elevated regions thereon. The nonwoven elevated regions comprise a first group of nonwoven raised elements and a second group of nonwoven raised elements, both raised relative to the base. The first group of nonwoven raised elements extends in at least a first direction and the second group of nonwoven raised elements extends in at least a second direction.Type: ApplicationFiled: November 2, 2001Publication date: May 8, 2003Inventors: Mark Alan Burazin, Jeffrey D.

Publication number: 20030079850Abstract: A papermaker's fabric, designed for use as a base fabric for a TAD belt, but also usable on the forming, press and dryer sections of a paper machine, has a plurality of warp yarns interwoven with a plurality of weft yarns. The warp yarns are of two types. Those of the first type weave with the weft yarns in a plain weave, while those of the second type weave with the weft yarns in a 2×2 twill weave. The warp yarns of the first type alternate with those of the second type, which undulate between adjacent yarns of the first type to give the fabric a desired openness.Type: ApplicationFiled: October 30, 2001Publication date: May 1, 2003Inventor: David S. Rougvie
