the absence of side gluing perfect gluing of the marginal leaves as well is also guaranteed the exemplified embodiment according to fig2 shows a nozzle head 14 with a multi hole nozzle designated as a whole by 15 amounts of 0 5 to 5 mm can be provided as distances between the holes in the multi hole nozzle 15 both in the area of the spine gluing 6 and in the area of the side gluing 7 in this case as well a spine gluing 6 is advantageously applied even in the absence of an actual side gluing which is about 0 5 to 2 mm wider than the book spine to be glued in order to reliably grasp the respective end pages if the multi hole nozzle 15 of the nozzle head 14 according to fig2 is designed for spine gluing 6 as well as for side gluing 7 it may be advantageous to select the nozzle hole diameter in the area of the side gluing 7 corresponding to the desired difference in the adhesive application thickness smaller than in the area of the spine gluing 6 in the exemplified embodiment the side adhesive strips 9 in the area of the side gluing 7 are distinctly narrower than the adhesive strips 8 in the spine area of the spine gluing 6 in the exemplified embodiment according to fig1 and 2 during operation either the nozzle head 10 or 14 is moved in the direction of the arrow 16 relative to.
