Open end spinning is a technology for creating yarn without using a spindle. It is also known as break spinning or rotor spinning. In this process the fibre sliver is separated into single fibres. The separated fibre material is brought by an air stream to a collecting surface from which it is drawn off while being twisted. It is a more recent method of yarn formation compared to Ring Spinning. It is generally used for coarser yarns but with very high output levels.
