Abstract: A cigarette-packing machine for packing cigarettes into hinged-lid hard boxes. The machine is fitted with an arbor-carrying drum (1) which is stepwise rotatable around its axis, and has a plurality of tubular matrices or arbors (3) projectingly mounted thereon. Hard cigarette boxes (P) are formed by blanks (F) and neck elements (C) to be folded about arbors (3) in a number of operative steps carried out at successive cigarette box-forming stations (S1 and S12), arranged around the arbor-carrying drum (1). In order to have the neck elements (C) accurately laid on the respective arbor (3), in their correct position relative to a box (P), the machine provides for the neck elements (C) and the blanks (F) to be separately fed.
