1. be used for the method for the temperature of the band (4) of advancing being regulated by blow gas or water/admixture of gas, wherein, the jet of a plurality of gases or water/admixture of gas extends on the surface of band, and be arranged such that of the impact (24 of the jet of described gas or water/admixture of gas to each surface of described band, 34) be distributed in the node place of two-dimensional network, described jet is ejected on each surface of described band, it is characterized in that, the impact (24) of described jet on a surface (A) of described band is not relative in another lip-deep impact (34) of described band with described jet, the jet of described gas or water/admixture of gas is from tubular nozzle (23,33), described tubular nozzle is by at least one distributor chamber (21,31) supply, the head of described tubular nozzle is extending apart from described distributor chamber a distance, so that for returning that gas or water/admixture of gas are parallel to the longitudinal direction of described band and perpendicular to the mobile free space that stays of the longitudinal direction of described band.
