Abstract: The invention is a mahcine for forming a full overlap-type shipping container from two similar blanks. A full overlap container normally has the end flaps of double thickness to withstand high top-to-bottom compression loads. This container has double thickness in both the end flaps and the laminated side walls. The machine is designed so that a first blank is transported on a main conveyor to a retractable stop located at a first combining section. Adhesive is applied to one of the side panels during transport. A second blank is then transported on a cross-conveyor to a second stop. This blank is lifted over the stop, and one side panel is positioned over the adhesive covered panel of the first blank. Pressure rolls then come into play to combine the panels. Assembly can now be completed on conventional equipment, such as folder-gluer, or may be done on an extended portion of the machine. In the latter case, the blanks are transported to a second combining station.
