SPINNING ROTOR OF OPEN-END SPINNING FRAME Russian patent published in 1995 - IPC

FIELD: textile industry; spinning. SUBSTANCE: bottom part of rotor body has ventilation ducts and air- guide channels 1.2-1.5 mm in diameter. The latter are located close to rotor trough. Longitudinal axis of each air-guide channel is inclined in direction of rotor rotation at acute angle to straight line running parallel to rotor axis through axis of channel outlet. Outlets of air- guide channels are uniformly located on the outer surface of bottom part of rotor body over circumference with diameter equalling diameter of circumference on which inlets of channels are located on inner surface of bottom part. Made on outer surface of body bottom part are grooves open on the end in zone of this surface with large diameter. The other end of grooves is communicated with gas-guide channels. Grooves are inclined in direction of rotor rotation relative to rotor radial plane running through open end of grooves at acute angle to it. EFFECT: higher efficiency. 6 cl, 4 dwg
