ABSTRACT:
The device comprises at least one toothed roller supported by a rocking lever, and adapted to contact the outer edges of the side flaps of the blanks. Each toothed roller is mounted on a pin by a conventional free wheel device so as to exert a sliding friction on the outer edges of the flaps only during a downwardly directed movement thereof, thereby bending the flaps in a direction opposite to the one naturally assumed by them due to the composite conformation of the stack of blanks.
