ABSTRACT:
A variable capacity buffer storage device 20 is disposed in series between a metal foil wrapping unit 16 and a paper blank enclosing unit 18 in a cigarette packaging apparatus. The storage device is in the form of an endless belt conveyor 31 having a plurality of rectangular compartments 33 configured to receive a block of cigarettes enclosed in a folded but unglued metal foil wrapper to retain the folded flaps from opening. A movable pulley 44 can vary the length of the storage run of the conveyor in response to breakdowns of the input wrapping or output enclosing units.
