ABSTRACT:
A case opening and sealing apparatus comprises a magazine having a plurality of flattened case blanks stacked therein, a conveyor underlying the magazine, and a plurality of suction cups for opening each case into tubular form for subsequent filling. Each forward case blank in the magazine is precisely ejected into proximity with the suction cups for opening purposes by a shuttle mechanism which functions to sequentially (1) engage a lower edge of the case blank to initially prevent removal thereof from the magazine, (2) move the case blank upwardly to release the lower edge thereof from the magazine, and (3) push the case blank downwardly onto the conveyor and into close proximity with the suction cups which function to open the case into tubular form.
