摘要: A high draft apparatus in a spinning machine for forming a spun yarn from a roving or sliver. The draft apparatus comprises back rollers, apron-provided middle rollers and front rollers and a gripping and a pressing means for a sliver disposed on the front end portion of the apron so that the arrangement of fibers in the drafted sliver is regulated and a high draft ratio can be attained.
