Abstract
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.
