Embodiment Construction

[0034] to eliminate image 3 Given the pronounced twill-like intersecting pattern 310 exhibited by the fabric taught in the Johansson patent shown, the present invention interweaves pairs of second machine direction (MD) yarns between the intersecting pairs, thereby spreading out the intersections. At least one yarn of the second pair of warp yarns forms part of the forming surface weave pattern. These additional yarns form the second warp system and result in a three-layer fabric structure. The crossing pairs are now the binding yarns that hold the top and bottom together and are part of the top weave. To increase the necessary machine direction (MD) tensile strength, a third system of warp yarns is therefore added below the second system of warp yarns. This third system of warp yarns forms the wear side of the fabric together with the interlocking wear side or intersecting pairs which are part of the weave of the bottom side.

Abstract

A papermaker's fabric for use in the forming section of a paper machine having two layers of cross direction (CD) yarns. Interwoven with the CD yarns is a system of longitudinal yarns. The machine direction (MD) yarns are grouped into alternating pairs of yarns, including: intersecting pairs with a first machine direction (MD) yarn and a second machine direction (MD) yarn, and a third machine direction (MD) yarn The second pair with the fourth machine direction (MD) yarn. Both first machine direction (MD) yarns and second machine direction (MD) yarns co-weave each cross direction (CD) yarn of the first layer and pass between the first layer and the second layer. The left and right warp yarns of the yarn pair are arranged in such a way that the length of the machine direction (MD) block formed by the abutment of like yarns in adjacent yarn pairs is equal to or less than that of the non-like yarn abutment of adjacent yarn pairs The resulting longitudinal (MD) block length. The third machine direction (MD) yarns interweave the first layer of CD yarns, and the fourth machine direction (MD) yarns interweave the second layer of CD yarns. In this way, warp-pair three-ply forming fabrics can be produced which minimize drainage problems and cross-point profile marks.

Description

technical field [0001] The present invention relates to papermaking technology. More particularly, the present invention relates to forming fabrics for use in the forming section of a paper machine. Background technique [0002] In the papermaking process, a web of cellulosic fibers is formed in the forming section of a paper machine by depositing a fiber slurry, which is an aqueous dispersion of cellulosic fibers, onto a moving forming fabric. Most of the water in the slurry is drained through the forming fabric, while the cellulosic web remains on the surface of the forming fabric. [0003] From the forming section, the newly formed cellulose web enters the press section, which consists of a series of press nips. A web of cellulosic fibers is supported by a press fabric, or typically between two such press fabrics, and passed through the press nip. In the press nip, the cellulosic web is subjected to compressive forces that force water out of it and cause the cellulosic...
