METHOD FOR CONTROLLING WEFT INSERTION IN JET LOOM AND WEFT INSERTION CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To accurately carry out detection of weft insertion abnormality of weft having high stretchability. SOLUTION: A transfer resistance-providing devices 26 and 26A are installed in the vicinity of inlet 221 of weft measuring and storing devices 12 and 12A. The transfer resistance-providing devices 26 and 26A are equipped with a rotary solenoid 27, a movable holding body 28 made of rubber and fixedly attached to an output shaft 271 of the rotary solenoid 27 and an immobile holding body 29 made of a rubber and arranged so as not to move. When yarn winding pipe 121 of weft measuring and storing devices 12 and 12A does not carry out yarn winding action, wefts Y1 and Y2 are held between the movable holder 28 and the immobile holder 29.
