Benefits of technology

[0011] This ratio provides a woven fabric structure with an improved tensile strength, a lower open space, and a reduced propensity in the seam region for marking the material sheet.
[0012] The ratio of the seam loops to the binders is 3:1, 2:1, or 3:2. The ratio of “3:1” means three seam loops, one binder, three seam loops, one binder, three seam loops, etc. The ratio of “2:1” means two seam loops, one binder, two seam loops, one binder, two seam

Problems solved by technology

However, the use of more than 50% warp yarns and the crossing of the looped yarns make the already complicated, prolonged, and expensive seaming process even more protr

Embodiment Construction

[0022] Referring now to the drawings, and more particularly to FIGS. 1-4, there is shown a woven fabric structure for a papermachine clothing or another belt, such as a filter or conveyor belt, including an array of cross-machine direction weft yarns 10, extending parallel to an edge of the fabric 1, and a last weft yarn 10a, defining the edge. An array of warp yarns 12 is woven through the weft yarns 10 substantially orthogonally to the weft yarns 10 of, and in machine direction of, the fabric 1.

[0023] It is shown in the embodiment of FIG. 1, which shows a fragmentary, enlarged, detail view of part of a seam region of a woven fabric 1, that a normal loop seam is made by reweaving the first machine direction warp yarn 12.1 back into the fabric 1 to form a loop 14. The second machine direction warp yarn (12.2 is not visible) is brought out of the fabric within the seam area. This leaves a space for the first machine direction warp yarn to replace the pathway of the second machine di...

Abstract

The present invention relates to a woven fabric structure including at least one array of warp yarns interwoven with at east one array of substantially orthogonally extending weft yarns, wherein each end of a warp yarn is extended beyond the last weft to form either a binder or a seam loop which can be interdigitated with similar seam loops of the opposing fabric end and joined by at least one pintle wire passed through a tunnel formed by the interdigitated seam loops. The inventive woven fabric structure is characterized in that the seam loops and the binders of the warp yarns possess a ratio above 1:1 and below 4:1.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a woven fabric structure including at least one array of warp yarns interwoven with at least one array of substantially orthogonally extending weft yarns, wherein each end of a warp yarn is extended beyond the last weft yarn to form either a binder or a seam loop which can be interdigitated with similar seam loops of the opposing fabric end and joined by at least one pintle wire passed through a tunnel formed by the interdigitated seam loops. [0003] 2. Description of the Related Art [0004] The woven fabric is for papermachine clothing, such as a forming fabric, a press sleeve, an extended nip press belt, a dryer fabric, a base cloth, for a filter belt or for a conveyor belt. [0005] A common form of seam is achieved by extending selected longitudinal (machine direction) warp yarns of the fabric beyond the last transverse (cross-machine direction) weft yarn to form a loop, the end of w...
