remains attached to the fabric web some of the filaments are entirely separated from the fabric and bind to the carding this accumulated flock is removed by worker cleaner rolls 140 142 commonly referred to as fancies the fancies 140 142 are located under the cylinder 116 and comprise bars that extend parallel to the longitudinal axes of both the cylinder 116 and the rotating worker rolls 108 the cleaner or fancy rolls carry densely packed semirigid filamentary material 144 commonly metal wire brush fillet that intermeshes with the carding of the rolls 108 as they rotate on the cylinder 116 in proximity to the cleaner bars 140 142 these cleaner rolls 140 142 clean the flock off the worker rolls and drop it into a pan not shown from which the flock is removed usually by suction the cleaner material 144 also conditions the wire on the worker rolls helping to keep it sharp the cleaning action is achieved by driving the fancy cleaner bars 140 142 to rotate in synchronism with the rotation of the worker rolls 108 and the cylinder 116 in order for the filamentary material or of the cleaner fancies to remove the flock from the carding of the worker rolls without being damaged the fancies must rotate such that the brush fillet is moving in the same direction as the carding wires of the worker rolls the synchronized movement of the fancies and worker rolls is illustrated in fig4 a 4b.
