Abstract (en)
[origin: EP3567143A1] A method of controlling weft insertion of an air jet loom includes the steps of: detecting a characteristic of a weft yarn (11) that is yet to be inserted; predicting a weft yarn arrival timing (TWp) at which the weft yarn (11) that is inserted in accordance with a specified weft insertion condition arrives at a specified position, on the basis of the detected characteristic of the weft yarn (11); when the predicted weft yarn arrival timing (TWp) is earlier than an earlier limit (TWf) that is predetermined relative to variations in the weft yarn arrival timing, modifying the weft insertion condition so that an actual weft yarn arrival timing is later than the earlier limit (TWf); and performing a weft insertion of the weft yarn (11) by the weft insertion nozzle (6, 7, 8) on the basis of the modified weft insertion condition.
