ABSTRACT:
In a blower arrangement for blowing a gaseous treatment medium onto a longitudinally moving material web, nozzle plenums are arranged above and below the web and extend essentially perpedicularly to the transport direction of the web. Each nozzle plenum is divided lengthwise into two channels arranged one above the other by means of a horizontal partition wall. At one end of the nozzle plenum, both channels are simultaneously supplied with treatment medium flow, whereas at the other end, both channels are interconnected for flow between them. The lower channel including the blower nozzles is further divided by a diagonally extending vertical separation wall forming two complementary wedge-shaped tapering partial chambers which both simultaneously supply treatment medium to the blower nozzle or nozzles.
