ABSTRACT:
A spinning aggregate is disclosed for spinning wrapped yarn. A drivable hollow spindle carrys a corotating sleeve with a binding yarn wound on said sleeve, a corotating positive false-twisting device into which the binding yarn and a sliver enter, said sliver being fed by means of a delivery mechanism having a pair of delivery rollers forming a nip, and a pair of withdrawal rollers following the hollow spindle. It is provided that the distance of the false-twisting device from the nip formed by the pair of delivery rollers of the delivery device is shorter than the median staple length of the sliver to be wound.
