US Patent 11390049 Method and apparatus for erecting cartons

In erecting a carton from a knock-down carton blank, the blank is placed on a base of a bed of a shuttle such that a bottom side panel of the blank abuts the base. The bottom side panel of the blank is then gripped with a gripper of the base and a top side panel of the blank is raised while advancing the shuttle in a horizontal direction so as to open said knock-down carton blank into a carton sleeve.
