A process and machine for making a corrugated or fibre board two-piece H-divider container in a single cycle of operation comprising erecting and gluing the H-blank upon itself and then erecting and gluing the body blank therearound. The vertical divider panels of the H-piece are folded at the bottom along a hinge line that includes two spaced crush score line areas interrupting a slit score line.

A machine for forming a paperboard or the like container from a preformed flat H-divider blank and a preformed flat body blank, the flat H-blank having two divider panels joined along a transverse hinge line and each of the divider panels being transversely flanked by an integral pair of foldable end panels, the flat body blank having a substantially rectangular bottom panel joined, along a longitudinally spaced apart pair of parallel transverse fold lines, to an opposite pair of substantially rectangular side panels, each of the bottom and side panels having a transversely opposite pair of foldable marginal flaps, said machine comprising: H-blank infeed means to fold the end panels of the flat H-blank substantially 90°relative to the divider panels, while maintaining the divider panels in co-planar flat condition, during movement of the H-blank to an indexed position in said machine; H-fold means comprising means for moving the partially folded H-blank from said indexed position into a split mandrel means while erecting the partially folded H-blank into an erected H-divider configuration; said split mandrel means comprising a spaced pair of mandrel shoe means defining a gap for the reception therebetween of the folded pair of divider panels of the erected H-divider, said mandrel means also defining surfaces for pressing thereagainst of each of the end panels of the erected H-divider; body blank fold and die plate means comprising a laterally spaced apart pair of body blank support means on the opposite side of said mandrel means from said H-fold means, said pair of body blank support means being movable inwardly and outwardly relative to one another between intermediate and compression positions thereof and also being comovable towards and away from said mandrel means between, respectively, folded and flat conditions thereof; said body blank support means in said flat condition and in said intermediate position being adapted to support a flat body blank in an indexed position relative to an erected H-divider in said mandrel means, said pair of body blank support means each having articulated elements adapted to translate movement of said support means towards said mandrel means into substantially 90°folding of the side panels of the body blank thereon relative to the bottom panel and around said mandrel means; said articulated elements also being adapted to effect partial inward folding of the marginal flaps of the body blank against corresponding edges of the end panels of the erected H-divider; said articulated elements also serving to fully fold the marginal flaps of the body blank onto corresponding edge portions of the end panels of the erected H-divider as a function of movement of said pair of body blank support means inwardly from said intermediate positions to said compression positions thereof.
