The ratio of the friction roller surface speed to the spinning speed is defined as the friction ratio. The friction ratio plays a great rule in twisting the fibres into a yarn, because the twist insertion mechanism is based on friction between the surfaces of the friction rollers and that of the yarn and increases with an increase in the friction ratio (Stalder and Soliman, 1989).

Abstract An analysis of the helical rolling process shows that the change in the axial speed of the roll along the length of the groove of the crossroller mill does not correspond to the required nature of the change in the speed of the deformed billet. The process proceeds under intense axial compression, as a result of which a significant part of the metal being compressed in the contact ...
