Abstract
A weft brake for an airjet loom includes a controlled drive for causing at least one thread guide to deflect the weft and thereby brake it, and a transmission which permits relative motion between the drive and the thread guide. The transmission is placed between the controlled drive and the thread guide to permit relative motion between the drive and the thread guide. As a result, rapid drive motion will not directly cause a rapid thread guide motion, resulting in a reduction in tension spikes during braking. Because the motion of the thread guide depends on the weft tension, when the weft tension is high, the amount of the deflection and consequent braking is less and the increase in weft tension caused by the braking is in turn limited. Moreover, even in the event of slackening of the weft tension, the weft still is kept tension. The drive may be in the form of a rotary drive and the transmission may be in the form of a helical spring.
