Abstract

PURPOSE: To effectively spread and guide a web by defining an air-supporting face in a device by carrier faces substantially parallel to a web to be supported and provided at float-nozzle boxes and at foil-nozzle boxes. CONSTITUTION: A web W runs supported by air blown in between a curved face K and the web W. Nozzle members comprise guide faces 28a, 28b, 38 and carrier faces 27, 37. A gas such as air, and the like is blown through nozzle slots 26a, 26b, 36 in the nozzle members, perpendicular to the direction of running of the web W, onto the carrier faces 27, 37. The nozzle slots 26a, 26b, 36 are, from one side, defined by the guide faces 28a, 28b, 38. In the direction of running of the web w, a first nozzle box and a last nozzle box are float- nozzle boxes 20. The nozzles 26a, 26b that blow against each other in each box in the nozzle box 20 produce pressurized carrier faces K. Between the nozzle boxes 20 and the foil-nozzle boxes 30, there are pressure equalization pockets 18.
