Abstract
A compression drum (1) for orderly groups of cigarettes (G) in automatic cigarette-packing machines has one or more compression pockets (2). Each compression pocket has a substantially rectangular cross-section and includes at least partly, movable sidewalls (3, 3', 4, 4') permitting the cross-section of a pocket to be varied between a maximum expansion condition, wherein an orderly group of cigarettes (G) to be packed is introduced thereinto, and a maximum compression condition, wherein the group of cigarettes (G) received in the pocket (2) is compressed. At least two adjacent sidewalls (3, 4 and/or 3', 4') of each compression pocket (2), one of which (3, 3') corresponds to a longer side and the other to a shorter side of the rectangular cross-section, are separate from each other and from the other sidewalls of the pocket and are movable independently from each other and each one with respect to the opposite respective sidewall (3', 4' and/or 3,4) so as to achieve a mutual movement of the walls of each pair of opposite sidewalls of a compression pocket (2) toward each other and away from each other.
