Apparatus for the formation of cigarette groups

Apparatus for the formation of cigarette groups of at least two parallel superposed rows of cigarettes comprising for each row of cigarettes a plurality of passageways (2, 3, 4) receiving the cigarettes from a feed hopper and terminating with a row-forming discharge end, and comprising also a stepwise-actuated endless conveyor (5) carrying a plurality of tubular receiving pockets (6) into which the cigarette rows are pushed according to the longitudinal direction of the cigarettes, each receiving pocket (6) being open at both ends so as to present an inlet end into which the cigarettes rows are introduced, and an outlet end from which the formed cigarette group can be ejected, each receiving pocket (6) presenting further at least one partition (7, 8) arranged at its interior and dividing the receiving pocket in as many pocket sections as the rows of cigarettes, wherein the improvement resides in the fact that the said partitions (7, 8) extend at the interior of the receiving pocket (6) from the inlet end towards the oulet end of the said pocket for a length which is a fraction of the length of the cigarettes, said partitions becoming progressively thinner in the direction of the outlet end of the receiving pocket, while the inner upper and lower walls (306, 406) of the receiving pocket converge in the direction of the said outlet end.
