ABSTRACT:
An apparatus for sequentially forming a plurality of generally longitudinally extending grooves in the peripheral surface of a filter rod includes a rotatable drum having a plurality of filter rod receiving channels formed in its outer peripheral surface for receiving filter rods to be grooved. The device includes filter rod indexing devices which engage the filter rods in the receiving channels. As the drum rotates about its central axis, the filter rod indexing devices are individually and selectively activated to incrementally rotate selected filter rods about their longitudinal axes through an angle corresponding to the angular spacing between adjacent grooves to be formed in the peripheral surface of the filter rod. A plurality of groove forming rollers are located at selected positions at the periphery of the drum. The rollers each have a plurality of groove forming blades projecting radially outwardly therefrom. A groove forming blade in sequentially positioned rollers sequentially form a groove in the filter rod after the filter rod has been rotated about its longitudinal axes from the position of a previously formed groove by the filter rod indexing device.
