Classification of Rotor Spinning Machines


Coaxial spinning units.                Biaxial spinning units.

The opening roller is arranged co-axially with rotor. The opening roller is arranged bi-axially with rotor
Proves  better for long staple Fibres spinning. Proves better for short  staple Fibres spinning.
There is air frictional losses only on one side of rotor & opening roller here is air frictional losses on both sides of rotor & opening roller.
35% less energy consumption. 35% more energy consumption.
Comparatively less  draw - off tension. High draw off tension which limits performance.
Fibres are always under control while passage from opening roller to rotor . Passage of fibres in long conduction channel from opening roller to rotor.
Fibres are fed in the form of web Individual fibres are fed
