摘要 |
<p>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.</p> |
