Abstract

A process for making collective packing unit boxes, comprising the steps of feeding a plurality of unit boxes by a first conveyor, thrusting the unit boxes one by one from the first conveyor to a second conveyor perpendicular thereto, thereby to cause the front side of each unit box to contact with the backside of the immediately preceding unit box, respectively, collecting a predetermined number of unit boxes together when the unit boxes are thrust from the first conveyor to the second conveyor, bringing down two flaps extending from the opposite edges of the collected unit boxes inwards, daubing an adhesive on the top flaps of the unit boxes, daubing an adhesive on the upper portions of the two sides of each unit box perpendicular to the contacting sides thereof, pressing a common lid onto the top of the collected predetermined number of unit boxes so that the lid may be adhered on the top flaps of the collected unit boxes, and folding the two opposite side edges of the lid so that the side edges are adhered on the upper portions of the two sides of the collected unit boxes.
