Abstract The present invention relates to a machine for erecting planar carton blanks to form glued boxes. The machine comprises a shaping die for erecting the blanks and a ram for pressing said blanks against said die, and means having at least one nozzle for applying warm, liquid glue in strings or spots to the portions of the blank to be glued together. The characteristic of the invention is that from the machine frame above the die there is suspended a pivot arm which is pivotally mounted at its upper end on a pin which extends parallel with one of the two main directions of the die, which directions extend perpendicularly to each other. The lower end of the arm supports a glue dispensing nozzle which is connected with a glue container via a conduit and the nozzle is pivotable between two limit positions located in the regions on opposite sides of the die. The length of the arm between the nozzle and the pivot pin of said arm is at least twice the distance between the limit positions of the nozzle, so that during the whole of its movement above a planar blank on the die the nozzle is located at a small distance from the blank sufficient to apply glue.
