Abstract
Device for contactless guidance of sheetlike material being dragged along a travel path, the device having a guide surface member extending spaced from the travel path and being provided with air-blowing nozzles, includes a guide zone formed in the guide surface member wherein the air-blowing nozzles are disposed in a manner that a common flow pattern or gap flow formed during guidance of the sheetlike material is determined essentially by a first velocity component in a direction of motion of the material along the travel path and by a second and a third velocity component directed towards two side edges, respectively, of the travel path, the second velocity component being associated with one of the side edges and the third velocity component being associated with the other of the side edge.
