OG exemplary drawing
 
1. A box forming device for forming a box provided with an internal partition wall, comprising:
a positioning area configured for temporarily supporting a blank coming from a blanks magazine and arranged between
a forming head movable in both directions along a rectilinear trajectory and configured for intercepting, in an operating position, a portion of the blank and
a box forming die having a tubular cross section positioned to receive the blank pushed by the forming head and configured to form an open box having a base and side walls around the base which define a housing compartment,
wherein the forming head has an operative end configured to make contact with the blank and provided with a through seat extending transversely with respect to the rectilinear trajectory of movement of the forming head;
a strap feeding member configured to feed a strap in the through seat, which is configured to temporarily accommodate the strap; and
a strap retaining member configured to retain the strap within the through seat while the forming head moves toward the blank, and to release the strap when the forming head arrives in the box forming die, so that the strap remains within the housing compartment of the box forming an internal partition wall which separates two adjacent compartments.
