System of detection of shed closed to shuttle passage in multished looms.

摘要

System of detection of shed closed to shuttle passage in a multi-step textile loom, constituted by sensitive control bars (15, 16) made elastically movable along the vertical direction, with a stroke at least equalling the vertical shift necessary for the shuttle roller to disengage from the corresponding thrust roller of the chain of dragging of the same shuttle (8, 9), as well as by two sensitive control blades (25, 26) opposite to each other, provided on the divergent side wall, on the rotary-comb facing side, of each shuttle (8, 9), the outward blade (25) of which is fixed and rigid, and the inward blade (26) is longer than the outward one, is rotary around a vertical axis, and by means of a retainer hook thereof keeps in a retracted position a lever pivot (34) urged by a spring to spring outwards relatively to the top shuttle plane (37).
