Abstract

To ensure that, when medium flows are used which are delivered by means of at least one delivery device and nozzles fed thereby against the surface of the material, a uniform flow velocity of the medium and hence a uniform energy exchange are achieved at the surface of the material, the total cross-sectional area of the nozzle orifices (11), relative to a plurality of adjacent nozzles (10), decreases in the outflow direction of the medium. The decrease in the total cross- sectional area can be effected by reducing the cross-sections of the nozzle orifices in the outflow direction of the medium and/or by increasing the spacing of the nozzles in the outflow direction of the heating or cooling medium.
