An apparatus for forming boxes starting from flat blanks (F) comprises an erecting station wherein the blanks (F), fed along a horizontal feeding direction (Y), are subjected to the action of a mandrel (101), movable vertically and adapted to push the blanks (F) against fixed folding means (104), arranged in proximity to the lower end of the run of the mandrel. The erecting station comprises a folding device with movable folding means (9) rotating on respective vertical planes, parallel to said feeding direction (Y), adapted to interfere with respective lateral flaps (F1, F2, F3, F4) of a T-shaped or double-T-shaped blank (F) to cause folding along longitudinal folding lines thereof, i.e. parallel to said feeding direction (Y), the device further comprising, or being associated to, further fixed folding means (103) adapted to engage with the blanks to perform, in an initial step of downward movement of the mandrel (101), foldings along transverse lines, consequently allowing the rotating folding means (9) to engage with the lateral flaps (F1, F2, F3, F4). |
