Abstract
Since drafting at Ring Frame is a majorinfluence on yarn qualities & ultimately tells on even fabric appearance,conversion of drafting to upgrade ring frame is a worthwhile exercise. Casablanca drafting represents the first development to improve the control over floatingfibres. Drawbacks of this drafting lead to Top Arm drafting thereby preventing slippage of back top roller. Though similar but with further development to ensure provision for varying pressure on top rollers came Second generation Top Arm drafting. Thenaroused the need for making changes in top rollers & cots, & nowdetachable types of top roller with softer cot on front roller are available.Offset drafting & Compact drafting represents the latest development indrafting system at Ring Frame.
