Abstract (en)
[origin: EP0554222A1] To provide a method of controlling weft insertion in a jet loom which can ensure safe and complete weft insertion through a shed even under the influence of a change in weft flying speed, acceleration or deceleration, due to a change in air injection from the auxiliary nozzles and provide uniform hand in the resulting fabric. Method of controlling weft insertion is adapted for use in a jet loom having at least one weft detector (32-36) for detecting the leading end of an inserted weft (y) for each weft insertion at a position defined by said weft detector (32-36) on the way of weft flying along a weft insertion passage of the loom to determine a time at which said leading end arrives at said position and a plurality of auxiliary nozzles (2a-2e,3a-3e,4a-4e,5a-5e,6a-6e) whose operation may be controlled according to a signal from said weft detector (32-36). The method is characterized in that said time at which the leading end of said inserted weft (y) has actually arrived at said position is compared with a reference weft arrival time, and fluid injection from any auxiliary nozzles (2a-2e,3a-3e,4a-4e,5a-5e,6a-6e) located upstream and downstream of said position of the weft detector are compensated for as required according to information from the comparison. <IMAGE>
