A ring tenser for a twisting machine. The ring is loosely fitted from above a head portion of the tenser body having a shoulder formed on an outer circumferential surface thereof and is placed on the shoulder of the tenser body so that a yarn unwound from a package is passed between the ring and the shoulder. One of the head portion of the tenser body and the ring is made of a metal material while the other includes a magnet.

Tension device

A spinning machine wherein a yarn knotting truck having a knotter provided thereon travels in a truck travelling spacing provided along a number of spinning units further includes an apparatus for automatically doffing winding packages which have yarns fully wound thereon. A doffing truck which has provided thereon a doffing apparatus travels in the truck travelling spacing.

Spinning machine with a doffing apparatus

A spun yarn is manufactured from a sliver through an action of a first fluid swirling nozzle and a second fluid swirling nozzle capable of swirling a fluid in a direction opposite to the direction of swirling of a fluid in the first fluid swirling nozzle. Fibers detached from a sliver between a front roller assembly and a first fluid swirling nozzle are caused to wind positively around the twisted fibers during spinning operation.

Method for producing spun yarns

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.
