- FIGS. 5 and 6 similar to the preceding ones, illustrate another variant in which the movable closure member is a deformable flap
- FIGS. 7A and 7B are partial sectional views illustrating the operation of a movable flap for closing the type of those illustrated in figu- 'res 1 and 2, with an exemplary asso- ciated control means, here in the form of pinion and rack, respectively in the maximum open position and maximum closure of the movable shutter; and
- FIG. 8A and 8B similarly illustrate a flap of the type of those shown in Figures 3 and 4, respectively in a position of maximum opening and maximum closure.
- FIGS. 1 and 2 illustrate a part of a blowing installation including a gas blowing device 10 noted according to the invention.
- the device 10 comprises, on either side of a strip-like material marked 15, the running direction being symbolized by the arrow 100, a hollow box 20, the strip material 15 flowing between the two boxes 20 in look.
- Each hollow box 20, whose interior space is noted 28 has a rear wall 21 to which is connected a tubing 12 for admitting blowing gas, the supply of blowing gas being symbolized by an arrow 101, a wall frontal or active 22 opposite to the wall 21, which is in turn facing the relevant face of the strip material 15, and two side walls 23.
- the wall 22 of each hollow box is equipped a plurality of blowing ports for directing gas towards the relevant face of the strip material 15.
- the blowing holes consist of tubular nozzles 30 projecting at least in part from the wall 22, but it may alternatively be provided that the blowing holes are constituted by holes in said wall 22 (variant not shown).
- each hollow box here has a profile which is variable in a direction D transverse to the direction 100 of travel of the strip material 15, symmetrically with respect to a median plane Q perpendicular to the plane of the strip 15, this profile being here arranged along a V-shaped dihedron whose ridge is noted 24.
- This is of course only an example, aimed at obtaining particular advantages, notably inherent to the nozzle effect obtained by the planes. diverging on each side towards the outside, as is shown schematically by the arrows 102 in Figure 2, and it may as well provide a wall 22 of flat structure, in accordance with traditional achievements in the field.
- each hollow box 20 is further equipped laterally, at least on one side thereof (here on both sides) with reference to the median plane Q which is perpendicular to the plane of the strip 15, a movable shutter member whose function is to selectively obscure some of the blowing orifices, in this case the inlet of some of the tubular nozzles 30, to adapt the width of the blowing zone to the width of the strip material concerned 15, said movable member having an edge adjacent to the inner surface 25 of the wall 22 provided with blow holes, and an edge adjacent to a side wall 23 of the hollow box 20.
- the mobile shutter unit simply change the position of the mobile shutter unit for selectively occluding an edge area, and thereby adapt easily and quickly to any possible bandwidth.
- the edges of the movable shutter member are and remain substantially parallel to the running direction of the strip, which ensures perfect adaptation to different band widths.
- a movable closure member in the form of a flap 50 which is rigid in its plane.
- the flap 50 is movable in translation in a lateral direction, as is schematized in FIG. 2 by the arrows 105, in the vicinity of and parallel to the inner surface 25 of the wall 22 equipped with tubular nozzles 30.
- FIGS. 7A and 7B make it possible to clearly understand the operation of such movable shutter members.
- FIGS. 7A and 7B show the entrance
- the flap 50 is in the maximum disengagement position, so that the nozzles 30.1 to 30.5 are all concerned with the blowing gas. This position corresponds to a maximum bandwidth.
- the arrow 105A recalls that the flap is in the maximum open position.
- FIG. 7B illustrates a maximum retraction position of the shutter 50, in which position the outermost nozzles 30.1 to 30.4 have their inlet 26 which is obscured, while the inlet of the nozzle 30.5 remains unobstructed, so that only the nozzle

- the flap 60 is pivotable, having an edge 64 adjacent to the inner surface 25 of the wall 22 equipped with tubular nozzles 30, and an edge 65 adjacent to the inner surface of a side wall 23 of the hollow housing. 20.
- FIGS. 8A and 8B there is illustrated a guiding means avoiding the jamming of the movable shutter of ob- 60 when moving, with end rollers 64 'flowing in slides 66.
- FIG. 8A the inlets 26 of all the tubular nozzles 30.1 to 30.5 are disengaged, while in FIG. 8B the inlets 26 of the tubular nozzles 30.1 to 30.4 are obscured, and the inlet of the tubular nozzle 30.5 is released.
- FIG. 8B the inlets 26 of the tubular nozzles 30.1 to 30.4 are obscured, and the inlet of the tubular nozzle 30.5 is released.
- FIGS. 5 and 6 illustrate yet another variant, in which the movable flap noted 70 is a deformable flap, for example articulated in the manner of a blind, which flap bears against the inner surface 25 of the wall 22 equipped with Lateral nozzles 30 and against the inner surface of a side wall 23 of the hollow box 20. Again, one edge 74 of the flap 70 remains adjacent to the inner surface 25 while the other edge 75 remains adjacent to the side wall 23.
- the movable flap noted 70 is a deformable flap, for example articulated in the manner of a blind, which flap bears against the inner surface 25 of the wall 22 equipped with Lateral nozzles 30 and against the inner surface of a side wall 23 of the hollow box 20.

- each movable closure member 50, 60, 70 is and remains parallel to the direction of travel 100 of the strip. It has thus been possible to achieve a particularly efficient gas blowing device, which makes it possible to easily and rapidly adapt the width of the blowing zone to the width of the band material concerned. Moreover, in case of concealment of certain These blowing, it has a higher flow rate than actually needed, which can further improve performance, including increasing the speed of travel of the band.
- the invention is not limited to the embodiments that have just been described, but on the contrary covers any variant using, with equivalent means, the essential characteristics mentioned above.
- blowing orifices may be arranged not in the form of tubular nozzles, but in the form of holes in the relevant wall of the hollow box (variant not shown), in which case the movable closure member will be arranged to selectively obscure the input (internal body to the box) or the output (body outside the box) of some holes, with the same adaptation effects as those described above for the tubular nozzles.
