The mechanism of twist insertion to the strand during ring spinning has been studied. The twisting of the strand occurs not only due to the rotation of twisting elements, but also due to the winding of yarn on the package. When the yarn is wound on a stationary cop by gripping and winding the yarn by hand, for every coil of yarn wind one turn of twist to the yarn is inserted. But the same yarn is over-end withdrawn from the cop, and all twists inserted during winding are removed during unwinding. Over-end unwinding rotates the yarn in the opposite direction. Since the yarn from the cop is over-end withdrawn during winding, the spindle speed is taken for calculating the twist in the yarn, whereas the flyer speed is taken for calculating twist in the roving due to the parallel unwinding of roving during spinning.
