ABSTRACT:
In an apparatus for contactless guiding of webs of material, in particular metal strips, by means of a gas medium, nozzle boxes are disposed above and below the web of material. The distances of the nozzle boxes from an imaginary, essentially horizontal center plane extending in the direction of transport differs individually or in groups. The positions of the outlet planes of the nozzle boxes are adaptable to the wave form, and each wave trough and each wave crest of the wave form is formed by at least two adjacent nozzle boxes.
