The operating stations comprise at least a pick up station (6) for the blanks (3), a gumming station (8), a folding station (9) and a station (10) for releasing the at least partly formed boxes. Each arm (5) comprises a pick up element (11) able to slide radially away from the carousel (4) to pick up the blank (3) directly from the pick up station (6) and to accompany the box (2) as far as a supporting surface (15) at the releasing station (10).
