The yarn is nipped securely and twisted by Murata’s Exclusive Twiste Belts. Slippage is almost zero. In this diagram, the force applied to the yarn, V, is divided into VT and VF . VT is twist force. V 1s
of V p d VF are decided according to V and angle 8. That is, in the nip system, the twist level,
