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.
