Dividing racks for parallelepipedal packing box, made from one cut-out cardboard flank, grooved and formed in order to build a plurality of adjacent individual divisions which are rectangular panels, rigid and divided by orthogonal and parallel cutting and grooving lines. The formed rack includes a double vertical central partition, two double lateral partitions extending from both sides of the central partition, single panel partitions orthogonal to the central partitions, single panels extending from the single panel partitions, and three single panels in one plane, in the continuation of the connection panels of the double partitions and the single partitions and parallel with the double partitions. When formed, the rack exhibits central segments dividing two panels of the double partition from the lateral partitions and form an outwardly protruding portion straddling the two panels, and locking slots at right angles with dividing lines between single panels and extension panels. Additionally, a machine for automatically forming racks having a station where stacked cut-out flanks are individually gripped, a station for forming and inserting racks adjacent to the gripping station, apparatus to convey each flank from the gripping station to above a forming station forming unit, a device to force the flanks through the forming unit and to push the formed rack into a box, and a system for supplying the empty boxes and removing boxes provided with rack.

A dividing rack for parallelepipedal packing box, made from on cardboard flank that is cut out, grooved and formed in order to build a plurality of adjacent individual divisions which comprise rectangular panels, solid with each other, and divided by orthogonal and parallel cutting and grooving line

A dividing rack for parallelepipedal packing box, made from on cardboard flank that is cut out, grooved and formed in order to build a plurality of adjacent individual divisions which comprise rectangular panels, solid with each other, and divided by orthogonal and parallel cutting and grooving lines, which, when the rack is formed comprises: a double vertical central partition aligned in a first plane, two double lateral partitions aligned in said first plane on opposing sides of said double vertical central partition, first single-panel partitions aligned in second planes orthogonal to said first plane between said double lateral partitions and said double vertical central partition, second single panels extending in continuation of said first single panels, third single panels aligned in a third plane parallel to said first plane and running between said first single panel partitions and said second single panels, wherein said double vertical central partition includes outwardly protruding portions defined by cutups which divide panels of the double vertical central partition and the double lateral partitions, and wherein said third single panels and said second single panels include slot means for locking said third single panels at right angles to said second single panels; wherein each protruding portion is defined by a flap made in one panel of the double vertical central portion which encroaches on the other panel; and wherein said cut-ups define an inwardly projecting portion in the vicinity of joints between panels of the double lateral partitions which is a transversal wedge for the rack at the base of the packing box.
