Open End spinning

Open End spinning

In the late 1960’s, a new spinning system was developed in Czechoslovakia by DREF. 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 with rotor speeds up to 140,000 RPM, and more efficient.

Several design of rotors are in use by different manufacturors of spinning equipment and are specialized for different types of fibers.
