Abstract (en)

[origin: EP2400050A2] Apparatus for determining status of weft insertion in a jet loom including weft arrival detection means (25) for detecting a weft inserted by injection of fluid is provided. The apparatus comprises clock means (K) for measuring a weft flying period (t1(s)) from the start time of insertion of a weft to the arrival time of the weft; and converting means (Co) for converting the weft flying period (t1(s)) into a weft flying angle (t1(t)) at standard rotational speed (R) of a weaving machine using the weft flying period (t1(s)) measured by the clock means and the standard rotational speed (R).
