<p>A device for automatic elimination of weft thread breakage to be used in a shuttleless loom comprising a weft thread monitor (1), a weft thread extractor with a reversible drive (4), actuating mechanisms for pulling out a broken weft thread, and an electric circuit unit which comprises, additionally, a unit (15) for integrity control of the extracted weft thread, a weft thread extractor upper position sensor (5) and ''OR'' logic elements (16, 17), enabling extraction of an unbroken weft thread to be prevented. In the event of incorrect triggering of the weft thread monitor (1) and non-response of the extractor upper position sensor (5) at the moment of extraction of the weft thread, the loom is started automatically.</p> |
