Abstract
An apparatus and processes for producing compound cigarette filters by horizontally assembling multiple filter segments onto the horizontally oriented transverse flutes of a continuous belt. Spaced apart hoppers are serially arranged above the belt, and each hopper contains at least one of the multiple segments of the compound filter being assembled. A transfer structure between each hopper and the belt serially delivers the filter segments to the flutes on the belt, and after such assembly the various filter segments are removed as a group from each flute of the continuous belt. The filter segments are then combined as a group with wrapped tobacco rods to thereby produce filtered cigarettes.
