ABSTRACT:
A device for concurrently forming a plurality of generally longitudinally extending grooves in a filter rod includes at least one pair of groove forming rollers located in a common plane, with their axes of rotation generally parallel and with their peripheries spaced apart. A plurality of elongated, generally arcuately shaped groove forming projections are spaced apart from each other around the circumference of each of the rollers. Each groove forming projections of one roller is in opposed facing, coextensive, aligned relationship with a different one of the groove forming projections of the other roller across the space separating the peripheries of the rollers. As a filter rod to be grooved passes through the space between the peripheries of the rollers, the rollers are rotated and the groove forming projections embed into the peripheral surface of the filter rod thusly forming grooves into the peripheral filter rod surface.
