Abstract
Apparatus for facilitating the manual erection and loading of a partially assembled paperboard carton blank. The machine includes a work table on which the carton blank is manipulated selectively to open the blank and close the bottom thereof by utilizing a vacuum system for selectively restraining major flaps forming the bottom wall of the carton. The opened carton blank remains immobilized on the work table for loading through the open upper end thereof. The major and minor flaps at said upper end then can be folded manually to close the loaded carton, after which the vacuum system can be deactivated to permit sliding of the loaded carton into a takeaway apparatus which can be a taping or sealing device or a conveyor for transporting the loaded carton to a remote work station, such as, for sealing. The table top may be pivotal. Also, the table top is provided with guide means for positioning the blank properly on the work table; said guide means can be adjustable for accommodating different sizes of box blanks thereon.
