Abstract: A two-layer paper machine fabric comprising one machine direction yarn system and two cross-machine direction yarn systems. The yarn systems are interlaced in accordance with an 8-shaft weave repeat. The yarns of the cross-machine direction yarn systems are positioned in two layers in such a way that the number of yarns in the upper system is double as compared with the lower cross-machine direction yarn system. To achieve a stable fabric each machine direction yarn passes during one weave repeat over two yarns in the upper cross-machine direction yarn layer and under one yarn in the lower cross-machine direction yarn layer. The passage of each machine direction yarn is reverse as compared with the passages of adjacent yarns. The yarns of the upper cross-machine direction yarn system form floats extending alternately over two and four machine direction yarns and the yarns of the lower cross-machine direction yarn system form floats extending alternately over two and four machine direction yarns. The longer float of the upper cross-machine direction yarn is always in alignment with the shorter float of the lower cross-machine direction yarn, and vice versa.

Abstract: A two-layer paper machine fabric comprising a machine direction yarn system and two cross-machine direction yarn systems, the systems being interlaced in accordance with a 16-shaft weave repeat. To achieve a fabric having advantageous wear properties, the lower cross-machine direction yarn forms floats spanning 13 yarns on the underside of the fabric and is interwoven in the fabric by passing it during one weave repeat over two machine direction yarns positioned close to each other in such a way that at least one machine direction yarn remains between said two machine direction yarns, said at least one machine direction yarn passing over the lower cross-machine direction yarn. The upper cross-machine direction paper-contacting yarn forms floats of shorter span as compared with the lower cross-machine direction yarn on the upper side of the fabric and is interlaced with at least two machine direction yarns per weave repeat.
