Patent ID: 8591675

Claim:
Method for acting on the temperature of a travelling strip by blowing gas or a water/gas mixture, whereby a plurality of jets of gas or a water/gas mixture, extending towards the surface of the strip and arranged in such a way that the impacts of the jets of gas or water/gas mixture on each surface of the strip are distributed at the nodes of a two-dimensional network, are sprayed onto each face of the strip, wherein, in order to reduce the vibrations of the strip which are induced by the blowing of gas or a gas/water mixture, the jets of gas or water/gas mixture come from tubular nozzles which are supplied by at least one distribution chamber and the heads of which extend at a distance from the distribution chamber in such a way as to leave a free space for the flow of the returning gas or water/gas mixture parallel to the longitudinal direction of the strip and perpendicular to the longitudinal direction of the strip and the impacts of the jets on one face of the strip are not opposite the impacts of the jets on the other face of the strip.
