Abstract
A packing machine has a main rotor (104) carrying hollow mandrels (141) to which foil and paper blanks are fed by respective feed units (160, 170) and folding/tucking devices to produce a packet with one end closed on each mandrel successively. Groups of cigarettes are fed to the mandrels from a twin-delivery hopper (110, 111, 112) the two deliveries (111, 112) of the hopper serving alternate pockets (121) of a single conveyor drum (102) which carries the groups towards the main rotor (104), a transfer drum (103) taking adjacent groups two at a time from the conveyor drum (102) to the rotor (104) and compressing each group during transfer. Each packet is removed from its mandrel (by pushing the cigarettes against the closed end of the packet) into a further drum (105) on which the second end of the packet is closed and adhesive securing folds of the packet completes its drying. The packet is then discharged through a stamper unit (106).
