Abstract (en)
[origin: EP3348688A1] A method for diagnosing weft insertion in an air jet loom, wherein the air jet loom includes a main nozzle, a sub-nozzle, a balloon sensor, a weft measuring and storing device, an end sensor, and a control device includes the steps of disposing a weft passage sensor on the side of the weft passage opposite from the main nozzle with respect to a center. The method further includes the step of determining a weft insertion failure as a looped weft failure when the number of the weft unwinding signals is normal and the weft yarn is detected neither by the end sensor nor by the weft passage sensor, and the weft insertion failure as the end arrival failure when the number of the weft unwinding signals is normal and the weft yarn is detected by the weft passage sensor but not by the end sensor.
