ABSTRACT:
A stack of sheets, in particular hinged-lid blanks B for cigarette packets, are disposed in a vertical stack S from the top of which successive sheets are lifted by a suction member and removed by mechanical means, e.g. by a pair of conveyors 21 provided with pushers 23.
The suction member may be a gang of sleeves 14 to which suction is continuously supplied, so that when a sheet B is engaged by the sleeves they are lifted automatically by suction in readiness for the pushers 23 to remove the raised sheet B, after which the sleeves again drop by gravity. The stack S may be inched around a J-shaped stack, or lifted by a pair of divergent conveyors 30 to which replenishing groups of blanks G are fed from underneath.
