ABSTRACT:
A device for closing the rear flap in a self-dimensioning machine for closing the upper flaps of parallelepiped boxes of the type including a base with support surface for the boxes, a couple of drive belts that can be motorized placed at the two sides of the support surface and that can be brought close to each other to make a drive engagement with the sides of the boxes and a head above the support surface, that carries devices for closing the front, rear and side flaps of the boxes and can be commanded to descend from a rest position to engage the above-mentioned devices with the upper flaps of the boxes and to close them. The device for closing the rear flap includes a rod for straightening the rear flap, that is pivoted on said the head and can be commanded to rotate from a substantially horizontal rest position to a vertical working position and to translate in the same direction as the boxes advancement to carry out the straightening of the rear flap, a touching group vertically mobile that can be commanded to descend towards the support surface up to a position depending on the height of the box and a lever pivoted on the touching group downstream from the straightening rod and flexibly kept in an angular position suitable for meeting with its inclined surface, during the descent of the touching group, the straightened rear flap and thus to cause the movement of the flap in a closing position.
