Abstract
Gate has two carton restrainers. First restrainer holds the lead carton in magazine stack while the second is inoperative. For take-down of the lead carton, first restrainer is moved away while at the same time the second restrainer engages and holds the carton next to the lead carton to prevent the same (and the cartons behind it) from popping out of the gate.
