Adjustable warp tension roll support

摘要

The warp threads (30) in a weaving loom are guided by a warp guide roller (16) and tightened by a warp tension roller (21). Both rollers (16, 21) are rotatably supported on a plurality of carrier brackets (15) spaced from each other along the loom weaving width and secured to a crossbar (2) operatively mounted in the loom frame by mountings (4, 6, 7). Each carrier bracket (15) has at its free end a bearing (15A) in which the warp guide roller (16) rotatably rests. Each carrier bracket (15) further carries at least one warp tensioning lever (19) journalled to the respective bracket (15) and having a bearing (19A) for supporting the warp tensioning roller (21). A cam drive (28, 29) biased by a spring (12) operates the warp tensioning levers (19) and thus the warp tensioning roller (21) into a warp tensioning position.
