Abstract (en)

[origin: EP3498902A1] If a count of unwinding detected by a balloon sensor is normal, and a weft yarn is detected by an in-weaving width sensor but not by an end sensor, a controller compares a weft detection timing of the in-weaving width sensor with a previously set threshold value of the weft detection timing of the in-weaving width sensor to estimate the location of a weft loop failure that is a weft insertion failure that has occurred.
