Abstract:
A machine is disclosed for erecting cases stored in upright, flattened positions in storage magazines. The machine includes means for extracting end member cases from the magazines, for dropping the extracted cases into drop chutes, for urging the cases in a generally horizontal direction out of the drop chutes, for opening the flattened cases by spreading the case sides apart, for tucking in lower case end flaps, for folding one case bottom panel in under the tucked end flaps, for applying adhesive to the bottom surface of the folded bottom panel, for folding another bottom panel in under the bottom panel having adhesive thereon, and for compressing the two bottom panels together.

Abstract:
A sealer characterized by a case erecting station at which pre-scored case blanks are erected into open-top cases having a squared configuration, a case sealing station disposed in spaced relation with said case erecting station, an intermittently operable conveyor for serially advancing erected cases from the case erecting station to the case sealing station, pivotal brake shoes for maintaining each of said cases in a squared configuration at the case sealing station, and a pressure applicator including a ram-actuated pressure plate for impacting against the flaps of each of said cases while the cases are maintained in a squared configuration by said shoes.
