- 9. Actions Involved in Draw Frame Drafting: It is the process of increasing length per unit weight of sliver. It is mainly due to peripheral speed of the rollers. Doubling: The process of combing two or more slivers into a single form is called doubling. Drawing: In the cotton industry the term is applied exclusively to processing on the draw frame, where the operation is one of doubling and drafting. Drawing= Drafting+ Doubling.

- 13. Conclusion Draw frame is a machine for combining and drawing slivers of a textile fiber (as of hemp for rope manufacture or cotton for spinning). Drawing is the operation by which slivers are blended, doubled and leveled. In short staple spinning the term is only applied to the process at a draw frame. In drawing slivers are elongated when passing through a group of pair rollers, each pair is moving faster than previous one
