Abstract
Wrapper portions, principally for use as uniting bands for joining together groups of component filter portions to form a composite filter rod, are obtained by longitudinally slitting a web, supporting the resultant strips on a plurality of suction tapes, guiding the tapes around angled pulleys to space them apart for delivery to a suction rolling drum, and cutting the strips into portions on the drum.
