ABSTRACT:
A forming machine including a load and feed chute for a set of die-cut cardboard pieces folded in a flat shape and laid on the chute perpendicular to the chute plane and parallel one after another, from which die-cut cardboard pieces are picked one by one and partially opened by a set of depression suckers that moves in a horizontal direction between a first position near the exit of the chute and suitable for the engagement of the suckers with one of the two coplanar adjacent sides of the nearest die-cut cardboard and a second position suitable for moving the engaged side of the sucker away from the opposite side of the die-cut cardboard with simultaneous rotation of the other two sides of the die-cut cardboard. The machine provides for squaring elements to complete and to square the partially open die-cut cardboard. A first flap closing device forms the closing fold of first bottom flaps connected with the other two sides of the die-cut cardboard and a second flap closing device forms the closing fold of second bottom flaps connected with the side engaged by the suckers and the opposite side of the die-cut cardboard.
