NOZZLE 0N HEAT-TREATMENT MACHINES FOR TEXTILE FABRICS AND THE LIKE Filed July 27, 1959 2 Sheets-Sheet 2 flqi IN VEN TOR.

Gustav [16}? ring llnited States Patent 3,002,700 NOZZLE N HEAT-TREATMENT MACHINES FOR TEXTILE FABRICS AND THE LIKE Gustav Miihring, 3 Salzmannweg, Stuttgart, Germany Filed July 27, 1959, Ser. No. 829,728 Claims priority, application Germany July 26, 1958 7 Claims. (Cl. 239-455) The invention relates to a nozzle for the treatment of Webs in heat-treatment machines for textile fabrics, foils or the like as it is, for example, installed in drying Inachines.

Nozzles of this known type are provided with a discharge slot of definite width which extends across the whole width of the web to be treated.

Nozzles are also known the slot width of which can be regulated by adjusting the walls forming the slot. The

slot of these known nozzles has a constant width over the whole length of the nozzle.

When treating fabrics which tend to strong sagging, a uniform treatment of the web by means of these nozzles is not possible, all the more since in practical use, on account of differing conditions of flow and pressure in the nozzles, a uniform discharge of the treating medium is very difiicult to obtain. Even presupposing that a uniform stream of air is discharged from the nozzles, a uniform heat-treatment of the Web would be questionable on account of the fabric web yielding to a certain amount of sagging and thereby being moved past the treatment nozzles at diiferent distances. This fact renders a uniform heat-treatment of such fabrics extremely difi'icult.

Fabric webs which are not supported laterally by. chains but fed through the drying machine in suspense are liable to cover intermittently the nozzle slots more or less. When employing the known nozzles the uniform treatment and consequently the uniform transport is considerably disturbed.

It results therefrom that the quantities of heat and air being discharged from the nozzles must be precisely controlled and kept uniform in their effect. These requirements have as yet not been met with by the nozzle constructions hitherto used.

It is the object of the present invention to eliminate these disadvantages and to provide a nozzle with a mouth adjustable by means of adjusting elements such as screws, eccentrics, cams, Wedges or the like so that the cross section thereof can be adjusted to any desired width at dilferent points of the nozzle.

According to another feature of the invention the nozzle mouth is provided with one or several spacer means projecting beyond the nozzle mouth in the transverse plane thereof and extendingpreferably through the entire length of the nozzle. These spacer means serve the purpose of keeping the nozzle mouth clear for the passage of the treating medium when the fabric web sags or even on the nozzle month. At the same time these spacer means serve to regulate the quantity of air or heat being discharged.

The mouth of the nozzle according to the invention is prevented from being closed by the spacer means so that the treating medium unifluenced by the respective distance of the fabric from the nozzle mouth can be discharged with the desired intensity. The novel nozzle permits a fabric web to be treated in a simple manner by exactly controlled gaseous or vaporous media so that optimum operating condtions in the machine are obtained.

The spacer means arranged according to still another feature of the invention as an elongated member has a steadying effect upon the run of the webs, especially when the latter are not guided at the edges by holding devices but are transported in suspense.

ice

The desired variation of the cross section of the nozzle mouth can also be obtained by varying the cross section of the spacer means. This can, for instance, be accomplished by adjustably arranging the spacer means. The cross section of the spacer means may thus be equally or unequally varied and correspondingly influences in turn the discharge width of the nozzle mouth.

Several preferred embodiments of the invention are illustrated by way of example in the accompanying drawings, in which is:

FIG. 1 a cross section through a nozzle with spacer means arranged therein;

FIG. 2 a view similar to FIG. 1 but showing, on a reduced scale, another form of construction of the nozzle and the spacer means;

FIG. 3 a similar view through a further form of construction;

FIG. 4 a top plan view of the nozzle according to FIG. 3;

FIG. 5 a top plan view .of the nozzle according to FIG. 1;

FIG. 6 a top plan view of the nozzle according to FIG. 2;

FIG. 7 an arrangement of several nozzles according to FIGS. 1 and 5, and

FIGS. 8 an arrangement of nozzles according to FIGS. 3 and 4.

FIG. 1 shows a nozzle mouth 1 formed by two side walls 2. An intermediate member 3 is mounted in said nozzle mouth 1 and extends through the whole length of the nozzle so that two nozzle slots 12 are formed. The

intermediate member 3 which preferably consists of sheet metal in the form of a hollow body is provided with two projections 4 extending beyond the nozzle mouth 1 in the transverse plane thereof and constituting spacer means for a fabric web B running past the nozzle. In order to be able to optionally adjust the width of each slot 12. the intermediate member 3 has its free longitudinal edge portions 8 releasably clamped between two superposed longitudinal rails 6 and 7 held together by a plurality of screws 5. Upon releasing the screws 5 the longitudinal edge portions 8 are allowed to be brought into any desired position and then clamped again so that different slot widths, for example a or b are possible. The Width of each slot 12 can in this manner be adjusted in itself to different sizes, for example growing from left to right, as is shown in FIG. 5.

In the modified embodiment shown in FIG. 2 a hollow intermediate member 3 of oval cross section is employed which likewise projects beyond the nozzle mouth in the transverse plane thereof by a predetermined amount and leaves two slots 12. The adjustment of the slot widths is accomplished by means of several screw bolts 9 extending transversely through the nozzle mouth 1 and the hollow intermediate member 3 and by appertaining nuts 10 screwed on the bolts 9 from outside the walls 2 of the nozzle mouth 1. This arangement, too, allows any desired adjustment of the nozzle slots to be accomplished.

As shown in FIG. 3, a special intermediate member can be dispensed with. In this particularly simple form of construction one of the two side walls is constructed in the same manner as described with reference to FIGS. 1 and 2, whereas the other side wall, indicated at 11, is somewhat higher so asto project beyond the side wall 2 by a predetermined amount, thus serving as spacer means. If in this type of construction the web of fabric B lies on the spacer, i.e. on the side wall 11, the treating medium can naturally be blown out from the nozzle to one side only. In order to prevent disadvantages likely to result therefrom, the side walls 11 serving as spacer means of nozzles arranged one behind the other are alternately arranged on the left and on the right, as is diagrammatically shown in FIG. 8. In this connection it should be mentioned that it is not necessary to have each nozzle adjusted individually. Adjusting means such as eccentrics, screw spindles or the like may be arranged in such a manner that a number of nozzles can be simultaneously adjusted while the machine is running.

Finally, it may be said, that the nozzle according to the invention not only allows the nozzle slots to be adjusted to any desired widths and configurations but also the distance between the nozzle and the web of fabric to be clearly determined. Moreover, the invention renders possible a vast adaptation to given conditions so as to provide optimum working conditions in the respective treatment machine.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

I claim:

1. A nozzle for distributing a heat treating fluid to uniformly heat-treat a continuous web of textile material or the like comprising means forming an elongated discharge slot terminating in a predetermined plane for directing pressurized treating fluid which is discharged as a concentrated jet in the direction of the middle axis of the nozzle cross-section, perpendicularly to the web of fabric in spaced relation to a predetermined path of travel, and transverse adjusting means spaced longitudinally of said slot and providing a variable width along said discharge slot for attaining different velocity flow of fluid along said slot, said nozzle including spacer means extending longitudinally of said slot and beyond said predetermined plane for maintaining said continuous web a minimum distance from said slot discharge.

2. The structure of claim 1, wherein the spacer means is constructed for substantially only a line contact with the web of the fabric.

3. The structure of claim 1, wherein the spacer means projects a distance outwardly of the discharge slot sufficient to preclude contact of a sagging web of the fabric with the walls of the slot.

4. The structure of claim 1; said spacer means comprising an intermediate member extending longitudinally of said slot and terminating in an edge disposed beyond said predetermined plane, said intermediate member forming a pair of variable width slots on opposite sides of said intermediate member.

5. The structure of claim 4; said intermediate member being transversely deformable and having a variable crosssection for varying the effective width of said pair of slots longitudinally of said nozzle.

6. The structure of claim 4; said intermediate member comprising a hollow body including a pair of longitudinal projections defining one side of said slots and projecting beyond said predetermined plane, and a clamp member disposed longitudinally of said slot below said projections, said hollow member including transversely displaceable edge portions adjustably received in said clamp member.
