             The scissors mechanism for the yarn side: This mechanism is mounted on the slide seat on the chest beam. The weft of the fabric and the main nozzle is cut after each weft insertion for the next weft insertion. The drive mode of the side scissors: the scissors cam rotates on the spindle, pushing the scissors arm to pull the scissors rod and driving the scissors to move the blade. Cut the weft according to the set timing after each weft. The yarn side scissors must cut the weft at each action, otherwise the next weft can not be carried out. The yarn side scissors are arranged between the main nozzle and the edge of the cloth. Cut the yarn time in 30°, at this time, the weft has been interwoven with the warp, the main nozzle high-pressure airflow has stopped spraying. The weft is cut behind, in the constant spraying air action, stay in the main nozzle, waiting for the next weft.Air Jet Loom
