Summary:Process and apparatus for the mass production of compound cigarette filters function to deposit granular filter material into the open ends of vertically oriented filter tubes. Predetermined amounts of diverse granular material are withdrawn by suction from sources of such material, and these amounts are deposited into the tubes. Solid filter segments seal the granular material within the tube. After one half of each filter tube is filled with granular material and sealed, the tube is inverted and the opposite end is filled in substantially the same manner. When cut in half each filter tube produces two cigarette filters.
