An apparatus is described for guiding a metal band (1) on a gas cushion with blowing boxes (4) which are disposed one after the other in the longitudinal direction (3) of the band and whose nozzle fields (5) which extend transversally to the longitudinal direction (3) of the band comprise hole-type nozzles (6) distributed over the field surface area and slotted nozzles (8) along the edges (7) which extend transversally to longitudinal direction (3) of the band. In order to provide advantageous constructional conditions it is proposed that the slotted nozzles (8) along the edges (7) consist of several nozzle slots (9) which are arranged one after the other parallel to the edge and are inclined inwardly with respect to the edge (7) starting from the respective center (10) of the edge. |
