Claims

[Scope of utility model registration request]

A first weft detector 7 is disposed at a position where the tip of the weft that has been inserted normally on the opposite weft insertion side reaches, and a A second weft detector 8 is provided at a position where the leading end of the weft yarn cannot reach, and an abnormality in weft insertion is detected based on signals from these first and second weft detectors. In the weft insertion abnormality detection device for a fluid jet loom, a first abnormality detection circuit 9 outputs a weft insertion abnormality detection signal when the first weft detector 7 does not detect a weft;
a second abnormality detection circuit 11 that outputs a weft insertion abnormality detection signal when the second weft detector 8 detects a weft within a predetermined time after the first weft detector 7 detects the weft;
12. A weft insertion abnormality detection device.
