1,163,546. Warp stop motions. TOYODA AUTOMATIC LOOM WORKS Ltd. 29 Sept., 1966 [22 June, 1966], No. 43589/66. Heading D1E. If a shuttle does not box a shuttle feeler acts to release a warp tension roller so that, if the shuttle is beaten in, the warp threads are not damaged. The tension roller is attached to a pivoted lever 22 loaded by a tension spring 23 adjustably mounted on a lever 16 held against the force of a spring 17 by a latch 14. If the shuttle does not box a lever 2 is not pivoted and a member 7 is brought into the path of a cam operated lever 10 which on rising, releases the latch 14 to allow the spring 17 to release the tension roller. In a second embodiment movement of the sley release the latch 14. A sley operated third embodiment is described which utilises a weight to tension the roller and this embodiment (Fig. 7, not shown) has a lever (66) which varies the tension of the roller to maintain constant tension during the weaving cycle. |
