Abstract
A device for blowing gas on a face of traveling strip material has at least one hollow box having its wall fitted with a plurality of blow orifices enabling gas to be directed towards the face of the strip material. The hollow box is also fitted laterally on at least one side thereof relative to a midplane (Q) perpendicular to the plane in the strip with a movable shutter member having the function of selectively shutting some of the blow orifices in order to adapt the width of the blow zone to the width of the corresponding strip material. The movable shutter member has an edge adjacent to the inside surface of the wall fitted with the blow orifices, and an edge adjacent to a side wall of the hollow box.
