  • Forming groups of cigarettes
    Patent number: 4834116
    Abstract: Groups of cigarettes are formed by axially extracting cigarettes from the bases of two hoppers (10, 12), each having vertical columns (14, 20) spaced apart by a cigarette diameter. The columns of the hoppers are staggered so that a cigarette extracted from the rear hopper (12) enters the gap between adjacent cigarettes of the front hopper (10, FIG. 3). The base plate (22) of the front hopper is initially higher than the base plate (18) of the rear hopper to allow clearance during intercalation of the cigarettes.
