V-shaped nozzles for guiding and drying a web on an air cushion

An arrangement for the levitated guidance of a material web traveling in a travel direction, the arrangement comprising a plurality of nozzle boxes arranged above and below the material web and at a distance between each other in travel direction of the material web, means for supplying blowing air to the nozzle boxes, each nozzle box having a nozzle plate facing the material web, each nozzle box having longitudinal edges extending transversely of the travel direction of the material web, the nozzle plate having two plane surface portions extending from the longitudinal edges and inclined relative to the horizontal to form a V-shape, two groups only of at least two rows of round blow nozzles for directing a blow jet against the material web, wherein both groups extend adjacent to and parallel with respective one of the longitudinal edges of each nozzle box, each nozzle box having a longitudinal vertical center plane, the round blow nozzles having axes extending perpendicularly to the plane surface portions, such that the direction of the blow jet is inclined relative to the vertical center plane of the nozzle box, wherein the round blow nozzles of one group of two rows adjacent each longitudinal edge are offset in longitudinal direction of the rows relative to the round blow nozzles of the other group of two rows, wherein each group of at least two rows of round blow nozzle includes a row located farthest away from the longitudinal edge, and wherein the row of round blow nozzles located farthest away from the longitudinal edge of the nozzle box is located closer to the longitudinal edge than to the vertical center plane of the nozzle box.
