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°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.

Apparatus for inserting partitions, each having a central partition member, into open containers, each container of which has opposed spaced parallel end walls and opposed spaced parallel side walls forming a rectangular perimeter: (a) means for conveying said containers successively along a prescribed path through a partition inserting station; (b) means for moving said partitions respectively into said containers in said station with the partition member of each partition disposed at a sufficient angle with respect to the sides of its container that it is loosely received in its container; and occupies less space lengthwise from end wall to end wall in its container than the partition does when it is parallel to the side walls of its container. (c) twist means for twisting each of said partitions, after insertion into said container, for rotating said partition member from its loose angled position about parallel to the side walls of its container.
