Abstract
Means for and the method of expanding and transferring a carton from a stack of collapsed cartons in a magazine to a bucket on a conveyor wherein the collapsed cartons are extracted singly from the magazine first by a suction means and transferred to a second suction means which deposits the carton into the conveyor bucket. The cartons comprise at one end thereof two side flaps and a front flap which includes a tuck flap. Stationary cams are utilized to partially expand a carton while it is being transferred and pushing the front flap inwardly while the carton is partially expanded which spreads one of the side flaps outwardly. This side flap is then held while the front flap is released and the other side flap and front flap are spread outwardly from the inside. Finally, all the flaps are maintained in a spread position while the carton is fully expanded.
