Open End Spinning In the late 1960’s, a new spinning system was developed in Czechoslovakia. The principal behind open end, or rotor, spinning is similar to 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 around into yarn and comes out, wrapped up on a package, all ready to go to the next step. There is no roving stage or re-packaging (autoconer). This system is much faster, speeds up to 140,000 RPM, and more efficient requiring less labour (no winding).

The disadvantage is mainly that the open end is limited to coarse counts.
