Abstract

A magazine carries a plurality of flat, stacked, corrugated fiber-board partition blanks, each being cut and scored for folding into an 'H' partition. The flat blanks are successively removed, one at a time, by a suction stripper feed mechanism which transfers them to a conveyor which, after the end panels of each partition are folded 90.degree. by plows, delivers each partition in a longitudinal path to a carrier in a forming station. A vertically moveable forming head folds the blank transversely about opposed fingers and strips the blank from the carrier, downwardly. Then the folded blank passes through opposed converging plates where the panels are urged against each other and opposed reciprocating flap folding dies fold the flaps to acute angles with respect to the panels. Next, the panels pass between spring-loaded twist members to urge them to deflected positions and are, thereafter, delivered diagonally into an open container where, after about 75% of the blank is inserted, the twister assembly twists the same into an aligned position. Subsequently, a squaring head forces the flaps against the ends of the container and thereby disposes of the U-shaped partition members formed by the panels, parallel to and between the sides of the container.
