Patent ID: 7451588

Claim:
A driving system for open-end spinning machines, in particular of the rotors ( 8 ) of a front of an open-end spinning machine, characterized in that the power necessary for the driving of the spinning rotors is distributed between two electric motors ( 51 , 51 ′) respectively situated at the top-end ( 51 ) and tail-end ( 51 ′) of the spinning machine, by transmission by means of a common driving belt ( 55 ) of the rotors ( 8 ), the rotation of the motor ( 51 ′) being subordinated to the rotation of the motor ( 51 ) wherein downstream of the main pulley ( 54 ) moved by the motor ( 51 ) at the top-end, the belt ( 55 ) reaches the idle reference pulley ( 57 ) for the whole driving, an encoder ( 58 ) being positioned thereon, for indicating the linear rate of the driving belt ( 55 ) of the rotors, and on the basis of the values indicated by the encoder ( 58 ), the control unit ( 59 ) of the machine controls and drives both the motor ( 51 ) at the top-end and also the motor ( 51 ′) situated at the tail-end of the spinning machine.
