ABSTRACT:
A carton erector apparatus for setting up folding carton blanks and folding their bottom flaps. The apparatus includes a carton blank storage section, a carton blank set-up section and a bottom flap folding section. The carton blank storage section includes a magazine assembly for storing and urging knocked-down carton blanks towards the carton set-up section. The carton set-up section includes a carton opening assembly comprising a pivot arm assembly pivotally secured to the folding arm assembly. The pivot arm assembly is movable between first and second positions respectively parallel and perpendicular to the folding arm assembly. A grasping arrangement is secured to the pivot arm assembly to grasp the side panel of the forward carton in the magazine assembly such that movement of the pivot arm assembly and the folding arm assembly into their second positions is effective to set-up the carton blank into a tubular form. Bottom flap folding assemblies are provided to infold the bottom flaps of the set-up carton.
