6. Draw Frame is the operation by which
slivers are blended, doubled & leveled. In
short staple spinning the term is only
applied to the process at a draw frame.

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
