Abstract

The making of cigarette packs is started by transferring arrays of cigarettes into successive pockets of a transporting unit while the pockets are at a standstill, and by inserting blanks into discrete pouches which are adjacent the front sides of the pockets. The pouches and the pockets are then accelerated, and the blanks are partially folded to overlie the arrays of cigarettes in the adjacent pockets prior to joint transfer of arrays and blanks into the receptacles of a continuously driven endless chain conveyor. The arms are then decelerated whereby the chain conveyor extracts the trailing portions of the blanks from their pouches and the blanks are converted stepwise into inner envelopes. The making of second envelopes around the inner envelopes can begin prior to or after completion of inner envelopes.
