Weft feeding device for a fluid-jet weaving machine

摘要

To provide a weft feeding device which alleviates excessive tension acting on the weft (2) upon feeding of the weft (2) and inhibits breakage of the weft (2), the invention provides a weft feeding device which controls opening and closing of a gripper (12,13) in linkage with the motion of a pinch roller (7) coming into and out of contact with a length measuring roller (4). Preferably, a rotary solenoid (16) operates the pinch roller (7) and the gripper (12,13) alternately by a pulse width modulation method. <IMAGE>
