ABSTRACT:
An improved process for preparing fiber rods useful as cigarette filter tips comprises feeding a synthetic fiber tow through an air jet bulker directly into the garniture of a conventional cigarette filter making apparatus. The process allows production of filters with lower denier tow than has heretofore been possible while affording to the manufacturer greater versatility to change filter characteristics more readily.
