Abstract
A method and apparatus for packing batches of cigarettes, in which batches B are transferred from a hopper 10 into compression boxes 16 of an intermittent conveyor 14, and are then packaged (e.g. in soft packs) while passing along continuous conveyors 22, 30 and 38. Compressed batches B are transferred into U-shaped foil wrappers F1 in compartments 28 of the conveyor 22, when folding flaps 88 fold over the two sides of the wrapper before the transfer is completed (FIG. 4). In a modification, the batches are formed from a continuous stream of cigarettes (FIGS. 8 and 9), and any voids V in the stream are filled by an intermittent acceleration rotor 350 (FIG. 11).
