The Effect of Loom Speeds and Shed Heights on Beating Force

Abstract

A series of experiments was carried out on Picanol (president) loom in order to study the effect of loom speed and shed height on the beating – up force. The mathematical model of warp threads mechanics established by the researcher was used to predict the warp threads tension.The results obtained clearly show that as the loom speed increased the beating – up force also increased. However, with speeds up to 180 revs/min the rate of increase of the beating – up force is not pronounced, but at higher speeds there is a substantial increase in the values of the beating – up force. Furthermore, the results obtained also showed that the beating-up force increased as the shed height increased.
