the jet weaving machine revolution the method includes the step of supplying a further unseparated weft length forming a loop between the unseparated weft length in the open shed while the loop elongates due to the action of an inserting medium until the loop face emerges from the shed on the shed outlet side and removing the weft from the shed by a weft withdrawing device application_number US 31562589 A description during the weaving process in a known weaving machine the insertion of weft 1 across shed 2 of warp threads 3 is tracked and checked by weft stop motion 4 at the exit side of shed 2 upon performing the method as shown in fig1 3 weft stop motion 4 emits on determining short pick of weft 1 towards the end of shed 2 a signal to a control device 15 which thereupon stops the length measurement of weft 1 by measuring device 16 together with simultaneous prevention of the inlet of the pressure medium forming the inserting means into the inserting nozzle 5 by measuring the length of weft 1 a controlled regulation of its tensile stress upon weaving is performed simultaneously with the signal for weaving stoppage a signal for blocking cutter 6 is emitted for the purpose of preventing separation of weft 1 at the inlet side of shed 2 fig1 in the course of the stoppage of the weaving process renewed measuring maintains constant tension stress in free part 7 of the length of weft 1 for the purpose of preventing break off of the mispicked length 9 of weft 1 form the free part 7 of its length upon.
