ABSTRACT:
An apparatus for levitational guidance of a continuous web of material for the purpose of its heat-treatment is configured of individual zones. The form ducting of the zones has the shape of an U in the vertical longitudinal center section above and below the web in each case, the legs of the U being located parallel to the transport direction of the web. The legs adjacent to the web are equipped on the side facing the web with levitation nozzle ribs or nozzle areas. In the legs facing away from the web, a radial fan is incorporated in each U, the delivery direction of which is directed towards the turn joining the two U legs. Heating means are arranged to advantage in the heating zones in the region between the two legs of the U. Coolers may be incorporated to advantage in the region of the turn joining the two U legs.
