In a process of making multiple filters for cigarettes, a succession of uniformly spaced filter wads are secured to a continuously fed cover strip; this assembly is moved past (and in contact with) a filler head having a filling aperture while a suction device - disposed ahead of the filling aperture and above the wads - produces a partial vacuum within a space (between two adjacent wads) whereby filter material moves from the filling head into the evacuated space. The edges of the cover strip then are brought together and overlapped and finally are fixedly secured to each other. |
