ABSTRACT:
In a station for erecting tubular blanks in boxes, a gripping and raising unit engages a second lateral wall of the blank and subsequently raises the blank into a 90° rotation, so that the blank assumes, due to raising and rotating and because of the weight, a parallelepiped shape with a vertical axis. A first folder is operated by a first actuator in step relation with rotation of the blank and folds at least a first lateral wall of the blank adjacent to the second lateral wall, engaged by the gripping unit, to erect, the blank in a box with a vertical axis.
