Abstract (en)
[origin: US4527598A] Two sensors are arranged on the catch side of the weaving shed of the weaving machine. These two sensors scan the length of the weft-thread end which protrudes from the weaving shed beyond the catch side end thereof and define a range of reference or set values for the length of the protruding weft-thread end. When the front end of the weft-thread, upon standstill of the weft thread after the weft insertion operation, is located within the range of the reference or set values, there is not accomplished readjustment of the weft-thread brake. When the front end of the weft thread falls short or upstream of a first one of the two sensors which is placed close to the catch side end of the weaving shed, then the closure of the weft-thread brake is effected at a later moment of time during the next weft insertion operation. When the end of the weft-thread passes beyond or downstream of a second one of the two sensors which is placed further from the catch side end of the weaving shed, then the weft-thread brake is readjusted so as to close at an earlier moment of time. A minimum of weft-thread waste thus results and the ends of the weft thread always have substantially the same length.
