Fig. 1.12 Computation of Angle of Bite.. hi Fig. 1.12 above, the radial force P r tends to compress the stock, while tangential force p P r (where p is the friction between rolls and metal), acting towards the roll gap. As p is always less than 1, then p P r is some fraction of P r. The resultant of these two forces p P r and P r is Rj as formed by parallelogram.
