The present is a machine for forming an inside-outside Bliss-type H-divider shipping container. It is based on an adaptation of a Moen or similar type single cycle container former. These machines employ a split mandrel which is generally in the form of a rectangular prism approximating the inner dimensions of the container. The H-divider portion of the container is held within the mandrel while the body portion is erected thereabout. Opposed plows mounted on the mandrel are adapted to fold what will become interior flaps joined to the end walls. These plows are located so that at the assembly point of the container they are entirely within the confines of the outer boundaries of the mandrel. Located in this position, they cause no interference with the erection of the body portion of the container.

In a machine for forming an inside-outside Bliss-type H-divider shipping container, said container being made from an H-divider blank and a body blank and having a formed interior H-divider connecting opposite pairs of end walls about which a flat body blank is erected, the body blank having a rectangular bottom panel joined along each side by parallel score lines to foldable rectangular side panels, the bottom panel and each side panel having individual foldable flaps at each end for adhesive engagement with the exterior peripheral surfaces of the end walls, and the end walls each having foldable flaps adapted to lie along the interior surface of the side panels at each corner, said flaps being oriented normal to the end walls in the assembled container, the improvement which enables folding and assembly of the interior end wall flaps which comprises: (a) split mandrel means for receiving said H-divider blank, said mandrel means having opposing spaced apart inner surfaces lying in parallel planes, the volume defined between said planes being unobstructed to allow passage therethrough of the H-divider portion of the container, the lower portion of the mandrel means generally defining a rectangular prism approximating the inner dimensions of the container, the mandrel means having generally open outer side faces lying in planes parallel to the opposing inner surfaces and generally solid surfaces on the outer side faces lying planes normal to the planes of the inner surfaces; (b) opposed plow means for folding said endwall flaps, said plow means being located adjacent to the generally open outer faces of the mandrel means and having H-divider entry portions extending outside the prism planes defining the generally open outer side faces of the mandrel means, in order to engage and begin folding the H-divider endwall flaps, and having holding portions contained entirely within said side face planes so as to hold said flaps after folding in noninterfering positions while the body blank is folded and joined to the end walls of the H-divider; (c) H-fold blank forming means mounted above the mandrel means for forming the H-divider blank into an H-divider; (d) reciprocating downfeed means operatively associated with the mandrel means to insert the folded H-divider between the spaced apart inner surfaces of the mandrel means and cause the endwall flaps to be folded by the plow means; and (e) body blank folding means mounted beneath the split mandrel means for lifting and folding a body blank upwardly around the opposite generally open sides of the mandrel means and for folding the adhesive coated bottom and side panel flaps into uniting contact with the end panels.
