ABSTRACT:
Successive groups of axially aligned component filter portions are separately united by one or more wrapper portions while moving axially. The composite filter rods formed from the groups are separate, so that there is no need for a continuous rod cut-off. Composite filters, for attachment to cigarette lengths, are subsequently obtained from the rods by cutting at appropriate positions.
