Abstract
Cigarette filter rods having individual objects positioned at predetermined intervals therein are prepared by transferring the individual objects from a rotating horizontal pan to a rotating vertical wheel and then depositing the object into a web of filter tow. Each object is positioned within the moving web of tow. The web filter material and the objects positioned within the web are introduced into a rod-forming unit wherein the rod is formed. The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.
