Abstract

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.
