Abstract
In a packaging machine, particularly for producing hingedlid packets for cigarettes conveyed on an endless pocket conveyor (16) become partially wrapped in a wrapper section (20) during transfer to a further endless pocketed conveyor (24). In passing to the further conveyor the groups and wrapper sections pass through a forming member carried on an intermediate endless conveyor (22). Transfer of the groups is effected by cam-operated plunger units (26A) carried by a fourth endless conveyor (26). The machine further includes a packet transfer unit at which spaced packets are deposited on a suction belt (50) prior to delivery in abutment to a packet reservoir (54); and a blank feed unit (30) comprising a continuously moving endless feed conveyor (62) provided with reciprocating pulleys, the movement of which causes the conveyor to remain stationary to allow transfer of blanks from a stationary reservoir (60).
