For the formation of fleeces or webs with parallelized, hooklet-free fibres for pattern production or for spinning mills, a raw material undergoes preliminary drawing in a preliminary drawing frame and is then supplied to a feed arrangement, through which the raw material is supplied to a clamping point of an extracting device formed of two clamping rollers. The clamping rollers running at a higher speed than the feed speed of the feed arrangement pull out fibre tufts disentangled and parallelized on one side. Then the tufts are fed to a suction drum for doubling purposes. From the suction drum the web formed with one disentangled side is fed into a further preliminary drawing frame, into a second feed arrangement, then into a further extracting device and thereafter into a further suction drum. As a result of this second extraction treatment the tangled fibres still present are drawn out, disentangled and parallelized, and a continual web suitable for further processing is removed from the second suction drum.

A method and apparatus for straightening fibres in a sliver comprises subjecting the sliver to sliding frictional contact with a foraminous surface through which an airflow passes, the sliding contact having the effect of both straightening the fibres in the sliver to orientate them, and straightening the hooked ends of any fibres in the sliver, and the influence of the airflow serving to remove dust and/or trash from the sliver.

For working a web of woolen type yarns leaving a finisher card, a condenser head splits the web into parallel bands. The bands are delivered to pairs of rubbing rolls which reciprocate relative to one another to convert the bands to slubbings having false torsion. The slubbings are conveyed to spinning frames.
