ABSTRACT:
Flattened cartons or containers stacked in a hopper of a packaging machine are successively removed from the hopper by an extractor including a vertically reciprocable suction-cup carrier engageable with the bottom section of the lowermost carton in the stack which initially is coplanar with an adjoining lateral section. The latter section, during the descent, comes to rest against a stationary ramp; the incipient erection of that lateral section by its engagement with the ramp is accelerated by a pair of swingable arms flanking the ramp, these arms being pivoted into a vertical position for area contact with the side of the passing carton. Possible malfunctions can be detected by a pressure sensor communicating with the suction line or by a photosensor in line with an area occupied by an end section of the carton in the unfolded position thereof.
