High Quality Content by WIKIPEDIA articles! Open end spinning or open-end spinning is a technology for creating yarn without using a spindle. It was invented and developed in Czechoslovakia in Vyzkumny ustav bavlna?sky / Cotton Researching Institute in Usti nad Orlici in the year 1963. It is also known as break spinning or rotor spinning. The principal behind open end spinning is similar to that of a clothes dryer spinning full of sheets. If you could open the door and pull out a sheet, it would spin together as you pulled it out. Sliver from the card goes into the rotor, is spun into yarn and comes out, wrapped up on a bobbin, all ready to go to the next step. There is no roving stage or re-packaging on an auto-coner. This system is much less labour intensive and faster than ring spinning with rotor speeds up to 140,000rpm. The Rotor design is the key to the operation of the open-ended spiners. Each type of fiber may require a different rotor design for optimum product quality and processing speed.
