Embodiment Construction

[0025] Referring now to the sole drawing, FIGS. 1A, 1B and 1C, there is shown a compound forming fabric 100 having a weave repeat of 24 warp yarns and 48 weft yarns. Fabric 100 includes binder warp yarns B1, B2, B4, B5, B7, B8, B10, B11, B13, B14, B16, B17, B19, B20, B22 and B24 which are arranged in pairs B1, B2 and B4, B5 and B7, B8 and so on.

[0026] Fabric 100 includes top weft yarns 1, 3, 4, 6, 7, 9, 10, 12, 13, 15, 16, 18, 19, 21, 22, 24, 25, 27, 28, 30, 31, 33, 34, 36, 37, 39, 40, 42, 43, 45, 46 and 48 and bottom weft yarns 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44 and 47.

[0027] Further, fabric 100 includes bottom warp yarns W3, W6, W9, W12, W15, W18, W21 and W24.

[0028] Fabric 100 has a top weave 101 and a bottom weave 102. Top weave 101 is a plain weave. Top weave 101 of fabric 100 is formed by the weaving of the interchanging binder yarns B1, B2, B4, B5, etc. with the top weft yarns 1, 3, 4, 6, 7, 9, 10, 12, 13, 15, 16, 18, 19, 21, 22, 24, 25, 27, 28, 30, 31,...

Abstract

A compound forming fabric having a top weave and a bottom weave. The fabric includes binder warp/weft yarns, where the binder yarns are arranged in groups of at least two interchanging binder yarns. Each group of the binder yarns forms an integral part at least of the top weave. Per group of binder yarns the number of bottom warp/weft yarns only weaving the bottom weave is higher than the number of top warp/weft yarns only weaving the top weave.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to compound forming fabrics, and, more particularly to a section of a papermachine to manufacture graphical paper, board and packaging paper, or tissue paper. [0003] 2. Description of the Related Art [0004] Compound forming fabrics are known in the art. Compound forming fabrics include a top or paper side weave and a bottom or machine side weave. The top and the bottom weave are bound together by binder yarns which alone or in combination can be binder warp or binder weft yarns and therefore weave with the top and bottom weft yarns of the top and bottom weave or with the top and the bottom warp yarns of the top and the bottom weave. [0005] The binder yarns further can be integral or so called fabric born binder yarns thereby forming at least an integral part of the top weave. U.S. Pat. No. 5,152,326 describes a compound forming fabric having integral binder yarns arranged in pairs. Alte...
