ABSTRACT:
In the processing of rapidly hardening flowable substances, especially glue, it is important to avoid hardening of glue residuals within the nozzle unit during temporary interruptions of operation. For this purpose, a liquid, especially water, is supplied through a nozzle duct so that the glue is rinsed out of an end section (31) facing the nozzle orifice (17). By closing the nozzle duct (16), a water column remains in the nozzle duct (16) and seals it towards the outside.
