Abstract

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.
