WINDOW-SHADE MATERIAL.

Application filed April 4, 1918. Serial No. 226,759.
a specification.
This invention relates to material used in the manufacture of window shades and has for its special object the provision of such material capable of satisfactory use in place of ordinary window shade cloth and of relatively low cost as compared with such cloth.
A further object of the invention is to provide for reinforcing window shade material of this nature to enable it to withstand the wear and tear of ordinary usage.
The accompanying drawings illustrate the construction of my improved window shade material and the manner in which the same is made, and referring thereto:
Figure 1. is a perspective view of a portion of such window shade material.
Fig. 2. is a diagrammatic vertical section of an apparatus suitable for making such material.
Fig. 3 is a partial plan view of such apparatus.
Fig. a is a partial plan view of a combing means for removing excess of waterproof coating from the shade material.
My improved window shade material comprises a body 1 of suitable paper or similar material, preferably a strong fibrous paper, such as is known as Kraft Fiber, this paper being coated with waterproof coating, such as a suitable oil paint, on both sides, forming a tough waterproof material capable of use as a window shade material.
In order to protect the selvage or edges of this material from tearing when in use, I prefer to provide at each edge thereof a reinforcing strip or tape 2 which is secured to the body 1 in any suitable manner; for example, by suitable adhesive. This reinforcing strip or tape preferably consists of tough paper, which may be of similar material to the body 1, and is also coated with the waterproof coating above referred to, after it is applied to the body 1. The outer edge of each tape 2 is ad]acent the corresponding edge of the paper body 1, so as to form a reinforced selvage, of double thickness, for the paper body without folding of the paper body or of the tape.
In order to further reinforce the material, I prefer to provide in each reinforcing strip or tape, one or more reinforcing threads 3, one of which is preferably located adjacent to the outer edge of the strip and sheet material 1, these threads 3 being secured in position in any suitablemanner, and being inserted or embedded between the body 1 of sheet material and the overlying strips or tapes 2. One or more intermediate strips,
such as indicated at 4 in Fig. 1 maybe applied to the sheet or paper body 1 between the edge strips 2, such intermediate strips being for example of similar material to such edge strips and secured to the body 1 in the same manner. Reinforcing threads however, will not generally be required in the intermediate strip or strips, as the main purpose of such intermediate strip or strips is to enable the shade roller material to be wound on rolls tightly and uniformly without presenting the looseness which would otherwise be caused by the thickening of the material at the edges only. I also prefer to provide at least two reinforcing threads 3 in each of the reinforcing edge strips 2, so that said edge strips will not tend to buckle or wind unevenly.
My improved shade material may be made in the following manner: Acontinuous strip of the sheet paper 1 is drawn from a roller 6, then over the guide roller 7 and under a guide roller 8 so as to be passed through a body of waterproof'compound, such as oil paint, indicated at 9, in a tank 10. From said tank the paper is drawn upwardly over a roller 12 and then down to a winding roll 13 in such manner that the compound is given, opportunity to dry by the time it reaches the winding roller. Suitable brushes indicated at 14 may be provided for removing surplus paint and smoothing the coatof paint on the continuous strip 1 and suitable calendering means, indicated at 20 may be provided if desired. The edge strips 2 and intermediate strip or strips 4 are wound from rolls 15 and 17 respectively, passing over the guide rolls 7 in contact with the strip 1, and being secured to said strips by suitable means; for example, by adhesive material applied to the under side of the strips 2 and 4. For this purpose, said strips 2 and 4 may consist of paper strips gummed on one side, said gum being moistened by suitable devices, indicated at 18, so as to cause the strips 2 and 4 to adhere to the strip of the body 1. Similarly the reinforcing. threads 3 may be Wound from rolls 19 and passed between the strips 2 and the body 1 and be secured between said strips by the adhesion of the strips 2 to'the body 1 and by the action of the gum or other adhesive material, securing the threads or reinforcing means directly to the strips 2. To insure a firm hold on these reinforcing threads 3, the latter are spaced sufficiently from the outer edge of the strips to enable the gummed surface at the outer edge of each strip to come in contact with the body 1, but are'sufiiciently near tov such edge to prevent tearing of the edge for any noticeable distance. Doctor blades 21 may be provided for removing excess of paint from the shade material, said blades being serrated, if necessary, for more effec- .tive action.
reinforcing meansat the edges of the body 1 may be made by folding over said body 1 of sheet paper material at the edges thereof and securing it in such folded position by suitable adhesive,-such as gum. In any case the sheet material With reinforced edges is coated on both sides including the-reinforcmg edge strips, so as to present a uniform appearance, and by using suitable thin material for the reinforcing means-and a sufliciently heavy and opaque Water-proof paint on both sides of the shade, the reinforcing is not noticeable. I may use a tape already reinforced with a thread or threads, in-
formed as a continuous strip consisting wholly ofpaper, a reinforcing paper tape secured to said body at each longitudinal edge thereof, the outer edge of each tape being adjacent the corresponding edge of the paper body, so asto form a reinforced selvage for the paper body without folding of the paper, and a reinforcing filament extend ing longitudinally in said, selvage.
2. Shade material comprising a body formed as a continuous strip consisting Wholly of paper, and a reinforcing paper tape secured to said body at each longitudinal edge thereof, the outer edge of each tape being adjacent the corresponding edge of the paper body, so as to form a reinforced I .selvage for the paper body without folding of the tape or of the paper body.
Shade material consisting of a paper body formed as a continuous strip having reinforcing paper tapes secured at the edges thereof, said body having a waterproof coat ing on both sides theleof and said coating extending over said tapes.
4.:Shade material consisting of a body formed as a continuous strip formed Wholly of paper, reinforcing paper tapes secured at the edges of said body and reinforcing threads between the tapes and the body.
5. Shade material consisting of a body formed as a continuous strip formed wholly of paper, reinforcing paper tapes secured at the edges thereof, and a reinforcing paper tape secured to the body intermediate said edge strips.
6. Shade material consisting of a paper body formed as a continuous strip, a paper tape secured to said body at each'edge thereof, and two reinforcing, threads extending between each papertape and the paper body,
adjacent to the respective edges of the paper ta e.
In testimony whereof I have hereunto sub-- scribed my name this 27th day of March 1918.
