A box forming apparatus for forming a box from a pressed cardboard blank which has been introduced on a forming matrix. The apparatus has two rectangular end plates joined together by a bridge by means of a guide and bolt system in each plate. The guide and bolt system permits variation and adjustment of the height of the apparatus with regard to the machine support. Two winged plates are pivotally attached between the end plates, the winged plates pivoting freely without the aid of pistons or springs. The respective axes of rotation of each of the wings is located at their respective top edges. The pivoting of the wings is delimited by round profiles, or stops, located on the end plates at two separate locations. One set of the stops prevent motion inward towards the center of the end plates, while a second set of stops prevent motion outward away from the center of the end plates. The wings have a bevelled bottom edge for relatively free sliding motion as the wings contact the cardboard blank. |
