ABSTRACT:
An apparatus for forming grooves in the peripheral surface of a filter rod includes an endless conveyor device having a generally horizontal top conveyor flight which intermittently moves the filter rods through the apparatus. The endless conveyor device has a plurality of filter rod receiving pockets at spaced apart intervals along its length. The pockets in the horizontal top conveyor flight hold cigarette filters to be grooved at predetermined spaced apart intervals as the endless conveyor device moves the filter rods through the apparatus. A plurality of pairs of articulated grooving fingers are located generally below the horizontal top conveyor flight at predetermined spaced intervals along the top flight, and a plurality of pairs of articulated grooving fingers are located generally above the horizontal top flight at predetermined spaced intervals along the top flight. A groove forming blade is attached to the tip of each finger of each pair of fingers. As the fingers of each pair of articulated fingers move toward each other the groove forming blades embed in the filter rods carried on the horizontal top conveyor flight of the conveyor device thereby forming the grooves in the filter rods.
