ABSTRACT:
Telescoping slot nozzles for use with a rail assembly are disclosed. Each nozzle includes a fixed portion and at least one telescoping portion slidably guided in the fixed portion. Metal-to-metal contact in the nozzle is avoided, thereby allowing the nozzles to operate at high temperatures. The configuration of the nozzle discharge opening can be easily modified to form an air knife, depending upon the particular application. Each nozzle is independent of the others, thereby facilitating retrofitting existing ovens and maintenance of individual nozzles.
