ABSTRACT:
A machine to erect flat-folded cartons, especially such as carry beverage containers, from a flat-folded storage configuration to three dimensional carrying configuration. The machine feeds folded containers from a storage hopper, in singulated fashion, between two endless forwardly flaring vacuum belts which hold the carton sides and move them simultaneously therealong to initialy expand the container. The partially expanded container is then completely expanded and fastened by a cooperating over-head positioning chain structure and an underlying cam wheel and thereafter delivered for further operation. The assembly operations are sequentially timed. The vacuum belts are particularly configured to allow a continuous, rapid operation with low air flow.
