Pile loom

摘要

There is provided an apparatus capable of maintaining a pile warp tension at a desired value even under a high speed operation of a pile loom in a pile warp tension controller (40) of the pile loom. The pile warp tension controller (40) controls a biasing force relative to a tension roller (6) in synchronization with a relative motion between a reed (28) and a woven cloth (7) which is performed in correspondence with a pile formation, and also controls the biasing force relative to the a tension roller (6) so as to apply a tension in a prescribed period including at least a beating time for pile formation within a period where the relative motion is performed, which tension is lower than an applied tension in a period other than the period where the relative motion is performed, and the tension roller (6) is elastically deformable in the range of a winding of the pile warp (2). <IMAGE>
