ABSTRACT:
A nozzle for applying an air-curable adhesive to sheets of paper normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is moved, and the nozzle is then moved into an operating position for applying the adhesive. Also disclosed is apparatus for automatically returning the nozzle to its storage position with the end of the nozzle in the sump at the end of a cycle of operation, or when normal operation stops because of a power failure, for example.
