ABSTRACT:
In the drive for a textile working machine, for the synchronized yet independently operable drive of at least two shafts, brake-clutch units associated with each shaft are provided, which are driven by a common electric motor. To achieve a regulation and control having good dynamic properties and fast response, provision is made for the brake-clutch units to be controlled such that the rotatory speed of the driven shaft of the first brake-clutch unit is given as a required value, and the rotatory speed of the second brake-clutch unit is synchronized through the rotatory speed of the driven shaft of the first brake-clutch unit, systems being provided for establishing the rotatory speed ratio.
