Abstract (en)
The faulty weft removing device for a jet loom, comprises a weft breakage detecting means (18) disposed on the weft receiving side of the jet loom. A weft extracting means provided preferably with a pair of extraction rollers (26, 31) grips a broken weft that is broken from a weft extending from the weft feed package. The weft extracting means is capable of moving the pair of extraction rollers (26, 31) from a position near the cloth fell (W1) of the fabric toward the reed (4) of the jet loom, as to separate the broken weft from the cloth fell (W1). When rotating the pair of extraction rollers (26, 31) the broken weft is pulled toward the weft receiving side and the broken weft is extractd from the shed. A yarn removing suction device (21a, 21, 34) having a suction opening extending over the range of swing motion of the reed includes a first yarn detecting means (33) interposed between the yarn removing suction means and the gripping range in which the pair of rollers (26 ,31) grip the broken weft. A second yarn detecting means (22) is disposed on the suction passage of the yarn removing suction device (21a, 21, 34). A rotation detecting means (25) like e.g. a step motor provides for detecting the rotation of the pair of extraction rollers (21, 34) and a the computer (C) determines the yarn length broken weft on the basis of yarn detection information provided by the first and second yarn detecting means (22, 33) and information provided by the rotation detecting means (25). The device provides for restarting the loom only after removal of the entire lenght of the broken weft from the shed. <IMAGE>
