Abstract
Abstract The material is located at one side of the screen of a screen printing stencil, the other side of which has the reinforcing substance, for example curable plastic material, applied, uniformly distributed over the screen. To apply the substance to the material, the screen is located at the end of a closed pressure vessel into which the reinforcing substance is introduced and to which, further, controlled pneumatic pressure is applied when printing is desired, to flow the reinforcing substance through the openings of the screen, and bulge the screen outwardly, for example into contact with the material to be reinforced. After application of the material, the pressure is released, permitting the screen to return to normal position and spaced from the material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
Method of reinforcing material (7) having a textile surface, in which the material with the textile surface is exposed to a liquid reinforcing substance, and the reinforcing substance is applied to the surface by screen printing, said method comprising, the steps of providing a vessel (8) having a screen printing stencil (10) forming one wall thereof; locating said material (7) adjacent one side of the stencil with the textile surface facing the stencil; introducing the reinforcing liquid substance into the vessel, and hence on the other side of the stencil, distributed over the stencil; maintaining the level of liquid reinforcing substance within the vessel at a predetermined depth from the side of the stencil to which said substance is applied; subjecting the reinforcing substance within said vessel to fluid pressure to force the reinforcing substance through the screen into said material by subjecting the interior of the vessel to fluid pressure, the quantity of reinforcing substance being applied depending on the pressure to the reinforcing substance; and then releasing the fluid pressure from the vessel.
Claim 2
Dependent Claim
175 words
Method of reinforcing material (7) having a textile surface, in which the material with the textile surface is exposed to a liquid reinforcing substance, and the reinforcing substance is applied to the surface by screen printing, said method comprising, the steps of providing a vessel (8) having a screen printing stencil (10) forming one wall thereof; locating said material (7) adjacent one side of the stencil with the textile surface facing the stencil; introducing the reinforcing liquid substance into the vessel, and hence on the other side of the stencil, distributed over the stencil; maintaining the level of liquid reinforcing substance within the vessel at a predetermined depth from the side of the stencil to which said substance is applied; subjecting the reinforcing substance within said vessel to fluid pressure to force the reinforcing substance through the screen into said material by subjecting the interior of the vessel to fluid pressure, the quantity of reinforcing substance being applied depending on the pressure to the reinforcing substance; and then releasing the fluid pressure from the vessel.
Claim 3
Dependent Claim
28 words
Method according to claim 1, wherein the step of locating the material adjacent the screen comprises the step of intermittently positioning blanks of the material beneath the screen.
Claim 4
Dependent Claim
23 words
Method according to claim 1, wherein the step of subjecting the reinforcing substance to fluid pressure comprises applying pneumatic pressure to said substance.
Claim 5
Dependent Claim
16 words
Method according to claim 3, wherein the step of applying pneumatic pressure comprises controlling the pressure.
Claim 6
Dependent Claim
25 words
Method according to claim 1, wherein the pressure on the screen is maintained constant before, during and after application of said substance to said material.
Claim 7
Dependent Claim
77 words
Method according to claim 1, wherein the step of locating the material adjacent a side of the stencil comprises positioning the material adjacent the stencil with a slight distance or spacing therefrom and the step of subjecting the vessel to fluid pressure comprises subjecting said liquid reinforcing substance to pressure of a magnitude sufficient to deform the screen to span said slight distance and essentially contact said material to thereby apply said liquid substance to said material.
Claim 8
Dependent Claim
19 words
Method according to claim 1, further comprising the step of interrupting application of said substance by reducing said pressure.
Claim 9
Dependent Claim
54 words
Method according to claim 6, further comprising, after the pressure releasing step, the step of, applying vacuum to said liquid reinforcing substance by subjecting the interior of the vessel to a vacuum to thereby deform the screen to resume its position with said slight spacing and interrupt application of said substance to said material.
Claim 10
Dependent Claim
18 words
Method according to claim 1, further comprising the step of simultaneously punching the material while applying said pressure.
