Abstract
A composite forming fabric, formed from two separate interconnected woven layers, for use in a paper making machine. The machine side layer is a single layer N by 2N weave, such as a six-shed, 6.times.12 weave. Within the weave repeat pattern the warp yarns form two distinct floats of unequal length, and the weft yarns form floats of equal or unequal length. The weft floats are located substantially in a single plane, on the machine side of the composite fabric. The weave design provides the composite fabric machine side layer with improved wear potential and guiding properties, without adversely affecting its drainage properties. The paper side fabric layer may be of any woven construction; a plain weave or 2/1 twill is preferred.
