A method for calculating the shedding cam pressure angle in cam-driven looms has been developed. The main advantage of this method over the conventional drawing method is that, because of the mathematical treatment and the use of computers, the numerous mechanical factors involved can easily be taken into account and the precision significantly improved. There is also an analysis of the influence of the treadle pivot location and the harness movement on the pressure angle and the lateral force.
