Abstract

Weft insertion procedure in the looms of two concurrent lances, without a shuttle with an external weft feeding coil and with the two concurrent arrival and extraction lances equipped with tweezers, in which, by means of the In the event of a sore, a part of the weft yarn that was between the outer feed coil and the location of a first fabric selvedge on the adjacent side of the loom is pulled to the center of the fuller, and then, using the lance clamp of extraction, this part of the weft thread is grasped in the gripper of the arrival lance and is pulled to the location of the second edge of the fabric on the other side of the loom, characterized in that between the location of the first edge of the fabric and the trajectory of the arrival lance, a reserve of the weft thread is formed; the weft thread is cut between the location of the first selvedge and the thread stock; by means of the clamp of the arrival lance, the weft thread is tightened and pulled to the center of the fuller in the form of a loop, one of whose branches is constituted by the free end of thread formed by the reserve and the other branch by the thread part attached to the outer coil; the thread loop is grasped in the arrival lance clamp by means of the extraction lance clamp, and is tightened by pulling it towards the location of the second selvedge; the clamp of the extraction lance is opened when it is still at a certain distance from the location of the second selvedge substantially equal to the length of the weft yarn reserve at the same time as the fulling chamber is closed; and the thread-free stock is allowed to slide into the open extraction clamp to fully unroll it to the second selvedge during the end of the extraction lance stroke.
