In apparatus for the formation of a planar blank into a flanged dual-compartment container, an inclined feeder with a generally vertical discharge end at which the blanks are sequentially presented for transfer. Vertically reciprocating glue applicators are mounted forward of the discharge end for depositing glue on the leading blank prior to transfer. A transfer unit is positioned forward of the discharge end for transfering the blank to a posiition overlying a forming chamber and introducing a central fold therein. Opposed upwardly projecting retention bars are mounted over the forming chamber for engaging and retaining the fold. Dual forming heads vertically reciprocate over the forming chamber to engage the blank into the forming chamber and define dual compartments. The dual forming heads are of different heights and mount a flange setter assembly for vertical reciprocation therewith and relative thereto. The setter assembly includes different height flange setting bars peripherally about each forming head, the different height of the setting bars corresponding to the difference in height to the forming heads.

In apparatus for the formation of a planar blank into a flanged container, vertically reciprocating breaker rods for engagement with peripheral edge panels of the blank for a downward breaking of the edge panels over fixed breaker blocks prior to an inward folding of the container walls. Horizontally reciprocating glue applicators deposit glue on the downwardly broken edge panels at portions thereof overlapping as the container is formed. The formed containers are sequentially fed into a forming chamber incorporating serrated wall-defining inner vertical surfaces which engage the flanges and retain the containers for progressive downward feeding. Vertically reciprocating setter bars engage and downwardly deflect the flanges of the chamber-received containers.
