System of detection of shed closed to shuttle passage in multi-step textile looms |
摘要 |
System of detection of a shed closed to passage of a shuttle in a multi-phase weaving textile loom. This invention is comprised of the following: sensitive control bars 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 dragging chain of the same shuttle; two adjoining sensitive control blades, both are on the rotary-reed facing divergent side wall of each shuttle; the outward blade is fixed and rigid while the longer inward blade is rotatable around a vertical axis; and upon detection of a persistent entanglement by the control blades, a lever pin, kept in a retracted position by a retainer hook, is freed by movement of the retainer hook such that the lever pin springs outwards to protrude from the shuttle plane, pressing upon a sensitive control bar, generating a stop loom signal.
