ABSTRACT:
A book spine coating nozzle is provided with adjustable side sealing jaws for adjusting the nozzle width for different book thicknesses and having distinct, separate side glue outlets for depositing glue on the book sides. Glue flow control valves are disposed between the nozzle and outlets so the glue deposited on the book sides can be selectively and independently cut off or controlled.
