This presentation introduces Md Matiur Rahman and their topic on draw frames. It defines key terms used in draw frames such as doubling, drafting, creeling, and doffing. Drawing is the process where slivers are blended, doubled, leveled and drafted through roller pairs to reduce thickness. Doubling combines slivers into one, and drafting reduces linear density by drawing fibers out. Creeling and doffing refer to replacing and removing cans of sliver at the back and front of the machine.

5. Objectives of Draw frame

6. Different terms of DF
 Drawing : a process in shortstapple in which
the slivers are blended, doubled, levelled and
drafted by passing the slivers through a
serious of pairs of rollers each pairs of rollers
each moving faster than the previous one.
 Doubling : The process of combining two or
more slivers, rovings or yarns into one.

7. Drawing, Doubling & Drafting

8. Different terms of DF
 Drafting : The action of reducing the thickness
or linear density of the feed material by
drawing is known as drafting.
 Creeling & doffing : The operation of replacing
the cans of feed material at the back of the
machine and joining the new can full of sliver
to the old is known as creeling and that of
removing the full delivery cans from the front of
the machine is known as doffing.
