ABSTRACT:
In a station of a boxing machine, for withdrawing and erecting flat folded tubular blanks into boxes, a blank withdrawing rocker arm strips out a flat folded blank from a magazine and places it onto a operating member situated below and associated to an auxiliary conveying line. The auxiliary conveying line extends along a close loop path. Gripping suction cups associated to the operating member engage the lower side of the blank. An erecting arm with a shaped flap makes edge-resting sides of the blank rotate synchronously, about respective articulation lines adjoining to a lower side, until a corresponding box is erected. A shaped guide engages with the carriage and moves the box laterally with respect to the auxiliary conveying line, to insert the box into a corresponding seat on a box conveying line situated beside the auxiliary conveying line.
