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 cartons comprise at one end thereof two side flaps and a front flap which includes a tuck flap. The method of expanding the carton comprises partially expanding the carton, closing the front flap while the carton is partially expanded thereby spreading the second flap outwardly, holding the second flap open while spreading the first and front flaps outwardly by applying pressure from the inside surfaces thereof and fully expanding the carton while holding the first, second and front flaps in their spread position.
