ABSTRACT:
An improved pressure pad is provided for stably floating thin metal strip while heat treating the strip. The pressure pad includes an oval pad housing which is slitted adjacent the strip. An elliptical plenum chamber is disposed within the pad housing with a portion thereof spanning the slit and forming with the slit margins a leading and a trailing slot jet nozzle. Opposing jet streams of gaseous medium exit the slot jet nozzles and collide with one another to provide a zone of pressure which stably supports the strip.
