1. A method of providing rods for use in the manufacture of cigarette filter elements, each rod having individual objects placed at pre-determined spaced intervals along the length thereof, the process comprising:
(a) providing a continuous supply of rod filter material;
(b) supplying objects to a first hopper that provides a reservoir for objects;
(c) feeding objects from the first hopper to a second hopper;
(d) positioning individual objects within the supply of filter material at pre-determined spaced intervals;
(e) forming the filter material into a continuous rod having individual objects positioned at pre-determined spaced intervals within that rod;
(f) subdividing the continuous rod at pre-determined intervals; providing a continuous supply of wrapping material; and forming the filter material into a continuous rod by continuously forming the wrapping material around the filter material; wherein the first hopper is an upper hopper and the second hopper is a lower hopper, and the upper hopper is adapted to feed objects to the lower hopper by way of gravity feed; further providing reciprocating screen between the upper hopper and the lower hopper, the screen having a plurality of holes therein sized to allow the objects to pass individually through each hole.
