ABSTRACT:
A filter assembly machine on which a feed roller successively feeds groups consisting of two cigarettes separated by a double filter, and respective adhesive-coated connecting strips on to a roller comprising a cylindrical body having a number of equally-spaced peripheral cavities each housing a continuously-rotating roller defining, together with the respective cavity, an arched rolling channel approximately equal in size to the diameter of a group; each roller having two diametrically-opposed suction seats inside one of which a group is fed by the aforementioned feed roller. As the roller turns, the group expelled from the respective seat travels at least once along the rolling channel in such a manner as to be wrapped inside respective strip and, each time it comes out of the rolling channel, is fed into the opposite seat to that from which it was expelled; each group connected by strip subsequently being fed on to a pick-off roller.
