A gluing device (10) for a box forming machine (1 ), configured to apply liquid glue to a flat blank (2) of paper or cardboard having V-shaped grooves between a base (3) and a plurality of segments (4) connected to the base (3) and defining oblique faces (5) contained in the thickness of the segments (4), comprises: a supporting structure (1 1 ) for feeding the blank (2) to a gluing station by moving it in a feed plane along a longitudinal direction; liquid glue dispensing nozzles (13) which are movable along a predetermined direction parallel to the feed plane in order to spread glue on one or more of the oblique faces (5), where the supporting structure (1 1 ) comprises: two guides (14) shaped in such a way as to prevent transversal movements of the blank (2) and to slidably support lateral end portions of the segments (4) of the blank (2); positioning means (17) operating on the blank (2) to move it to a predetermined longitudinal position in the gluing station; locking means (26) for holding the blank (2) in place so it is in the same plane as the feed plane while it is at the predetermined longitudinal position. |
