Abstract

See full text

An apparatus for applying adhesive to a book block spine has an application nozzle, a nozzle opening of the application nozzle being variable and able to be adapted to the thickness of a book block to be processed. The application nozzle has a first chamber for providing adhesive and a second chamber. A first slide is provided in the region of the first chamber for changing a width of the first chamber. A second slide is provided in the region of the second chamber for changing the volume of the second chamber. The changing takes place in such a way that, when there is a change in the width of the first chamber, the sum of the volume of the first chamber and the second chamber remains constant. The apparatus allows a strictly defined application of adhesive possible even when there is a changeover to a narrower book block spine.
