SPINNING RING:
Spinning ring is a narrow, vertical, cylindrical steel band with a horizontal flange. The function of steel ring is to serve as a track upon which traveler may revolve. In this way it assists in twisting the yarn and guiding it to the bobbin as well. Vertical part is known as web and horizontal part at the top of the ring is called as flange. For course count, diameter of the ring will be more and vice versa. Range of ring diameter is 35-75mm.life of spinning ring depends upon,
Ø Quality/material of spinning ring
Ø Spindle speed
Ø Count of yarn
1.1 RING TRAVELER
Twisting and winding both requires assistance of the traveler which revolve s freely around the spindle on the ring. Traveler is a short steel wire having shape like ‘C’. As it travels on a ring track so is called as ring traveler. It is hardened, tampered and polished. Its motion is free on the ring flange. For course yarn/count heavy traveler is used and vice versa. To clean the traveler from lint there are some projecting pieces called traveler cleaners/clearer.
1.2 SPINDLE
After drafting yarn come on spindle which has duvet on it known as bobbin. Spindle is short, light shaft which may be rotated on its own lengthwise axes to insert twist and to wind yarn into some desired form of package. For ring spinning frame, each spindle carries a small pulley by which it is driven. Function of spindle is.
Ø To rotate delivered fibres from front roller nip for twist insertion.
Ø To wind the yarn produced on bobbin as fast as it is twistead.

BOBBIN:
As it is practically not possible to spin directly on the bare spindle, so, some form of bobbin on spindle is used. A spinning bobbin is long, narrow cylinder usually made of plastic. A bush inside the bobbin in upper half portion is used to fit it on spindle firmly. So, bobbin speed will be the same as spindle speed.
