Abstract
Abstract An elongated carton supporting rail is mounted on a frame along with means for guiding an opened-out upright carbon blank to a predetermined position, with the edges of its bottom minor flaps resting on the rail. Flap closing elements automatically engage the bottom minor and major flaps of the carton in sequence immediately following the engagement of the carton with a switch lever when the carton is in the proper position on the rail. The minor flaps are folded above the carton supporting surface of the rail and in parallelism therewith, and the major flaps are folded below the carton supporting surface of the rail. The carton is then filled while supported on the rail, and thereafter is engaged by a pushing element and slid longitudinally off the discharge end of the rail.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
166 words
An erector and holder for a shipping carton having first and second pairs of closure flaps comprising a frame, an elongated rail mounted on said frame, said rail having a carton supporting surface and having a discharge end, means on said frame for holding an opened-out carton blank in a predetermined upright position with the edges of said first pair of flaps resting on said rail, means for folding said first pair of flaps inwardly toward one another on top of said carton supporting surface to allow the carton to descend to a position where said rail is between the second pair of flaps, and means adjacent opposite sides of said rail and movable toward said rail for folding said second pair of flaps inwardly toward one an other to dispose them below the supporting surface of said rail while said first pair of flaps continue resting on said top surface, with said rail forming a slide for discharge of the carton from said discharge end.
Claim 2
Dependent Claim
166 words
An erector and holder for a shipping carton having first and second pairs of closure flaps comprising a frame, an elongated rail mounted on said frame, said rail having a carton supporting surface and having a discharge end, means on said frame for holding an opened-out carton blank in a predetermined upright position with the edges of said first pair of flaps resting on said rail, means for folding said first pair of flaps inwardly toward one another on top of said carton supporting surface to allow the carton to descend to a position where said rail is between the second pair of flaps, and means adjacent opposite sides of said rail and movable toward said rail for folding said second pair of flaps inwardly toward one an other to dispose them below the supporting surface of said rail while said first pair of flaps continue resting on said top surface, with said rail forming a slide for discharge of the carton from said discharge end.
