ABSTRACT:
A sliver-delivering machine such as a card and a sliver coiler are each provided with an independent drive including a frequency-controlled free-phase motor. In addition, a frequency converter is connected in common to the motor of each drive for supplying power to each. The motors of the sliver-delivering machine and the coiler have a load-dependent speed characteristic, for example, each is an asynchronous motor with a maximum slip of 3% over a delivery speed range of up to 300 m/min.
