Abstract
Disclosed are carton assembling method and equipment for sucking and taking out flatwise folded cartons one by one from a magazine by means of suction cups, unfolding each carton squarely on a conveyance path while transferring it downward along a rotative path, and supplying the thus-unfolded cartons to an encasing machine by means of a conveyance mechanism. Each carton is held squarely by a pair of stoppers, utilizing its reaction force acting in the returning direction. Thereafter, the carton is reverse-folded against such reaction force and then unfolded again to remove the folding tendency of the carton acting in the folded direction, thereby permitting the carton to hold itself in a square shape. And at the time of reverse folding, the flaps of each carton are expanded so that a contents charging conveyor can be disposed in close proximity to the cartons.
