ABSTRACT:
There is disclosed a device for closing the front strap of a parallelepiped box. Such device comprises an articulated parallelogram composed of an upper fixed horizontal side, a lower mobile horizontal side and two normally vertical connecting sides. A rotatable arm has its lower end hinged to the inlet end of the lower side of the parallelogram and is also linked to the upper side of the parallelogram by a rigid rod hinged at its ends. The lower side is at a distance from a support surface for the box, which is just less than the height of the box, so that, when the advancing box encounters the inlet end of the lower side of the parallelogram, the lower side is enabled to rise and to cause the rotatable arm to rotate towards the front side of the box to engage the front strap thereof and to move it to the closing position.
