Ring Twisting Frames for Ply Yarn
topic
Ring twisting frames twist single yarns or ply two or more ends together using a rotating traveller on a ring that inserts one twist per traveller revolution at ring speeds of 5000 to 15000 revolutions per minute, with simultaneous winding as the traveller lags behind the spindle speed building the twisted yarn onto the ring bobbin through the same traveller-spindle speed differential that inserts twist.
Role
Provides versatile twisting capability for both single yarn ply twisting and multi-end cabling in a simple and easily maintained machine configuration that remains widely used for natural fibre yarn twisting, specialty yarn production, and medium-volume applications where TFO capital investment is not justified, with ring twisting being the primary twisting technology in cotton hosiery yarn production and many natural fibre specialty yarn applications.
