Effect of Easing Device on an Air-Jet Loom of Double Back Rest System

Abstract:

In order to release the influence of shedding motion on warp tension fluctuation, easing device is often set on short looms with single back rest system. With the decrease of the beam’s diameter, the wrapping angle formed by warp and the active back rest will become bigger, and the effect of the easing device will be more significant. However, the wrapping angle of the double back rest system is a constant while the change of the beam’s diameter. The effect of easing device on air-jet looms of double back rests system is analyzed in this paper, and conclusion has been made that the easing device can be eliminated on the double back rests system.
