A method and apparatus for forming a reinforced half-slotted container in which each of the side walls is formed by outer side wall and a reinforcing panel which is the same size and height as the outer side wall. The reinforcing panel is attached to the outer side wall along a score line at the top of the outer side wall. In the method, either the two interior reinforcing panels or the two exterior reinforcing panels are adhered to their outer side walls and then the other two reinforcing panels are adhered to their outer side walls. The container is then formed in the normal manner to fasten the glue joint to the opposite side wall. The apparatus has a first forming station in which the interior reinforcing panels are glued, folded over and adhered to the outer side walls, and a second forming station in which the exterior reinforcing panels are glued, folded over and adhered to the outer side walls. In the first forming station, the conveyors and hold down means act against the exterior panels and walls, and in the second forming station the conveyors and hold down means act against the interior panels. The reinforcing panels are the leading panels through the apparatus. The device for folding the reinforcing panels back upon the outer side walls is a simple spring mounted arm and detent. The order of the forming station may be reversed.
