Patented Jun'e 9, 1931 UNITEDy sTATEs PATENT OFFICE HARRY M. ROSS, F INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF TO IBEVERIDGE PAPER COMPANY, 0F INDIANAPOLIS, INDIANA, A CORPORATION PROCESS OF DECORATING PAPER Application led August 11, 1928. Serial No. 298,927.

This invention relates toV a process and means for decorating paper, and particularly that class of paper used for calendars, bristols, cover paper, photo mounts, boxboard and the like, having a multi-colored or shaded surface or surfaces.

The object of the invention is to process a paper having a smooth surface or a more or less embossed surface by brushlng a coloring material thereon in streaks for effecting an appearance or surface decoration representing wood grains, or having a bark-like appearance, etc.

The full nature of the invention will be understood from the accompanying drawings and the yfollowing description and claims: v

Fig. 1 is a diagrammatic illustration of an apparatus for carrying out the process. F 1g. 2 is a View taken on the line 2-2 of Fig. 1. Fig. 3 is a plan view of the decorated surface of the paper. Fig. 4 is the same as Fig. 3 showing the same surface upon a slightly embossed sheet. 4

In the drawings there is illustrated a paper roll which is suitably supported to carry a roll of relatively heavy, smooth surfaced paper, which has a base color. The paper is drawn form the roll 10 about the guide roll 11 over the counter roll 12 and caused to pass between -said counter roll 12 and the embossing roll 13. The embossing roll is provided with a suitable embossing surface 14 adapted to impress designs of various character in the paper. v As shown in Fig. 1, the embossing roll 13 is separated from the counter roll 12 so that the paper will not be embossed and will present a smooth surface for receiving the coloring material. As illsutrated by dotted lines in Fig. 1, the embossing roll 13 may be lowered or adjusted to a position whereby it will engage and emboss the paper when desired. The roll 13 is adjustably mounted so that the extent o-r depth of the embossed design may be varied, whereby the paper may have a very slight embossing to produce the desired results, such as illustrated in Fig. 4, as distinguished from a smooth surfaced paper illustrated in Fig. 3. The paper is then carried under the guide roll 15 and about the brushing rolls 16 to the carrying roll 17. Positioned to one side of the brushing rolls 18 and having axes slightly above the axis thereof, there are corresponding coloring rolls 18. Y

The rolls above referred to are also suitably supported and driven in the usual manner. However, the brushing rolls 16 are caused to rotate at substantially twice the speed of the paper passing thereabout. Thel speed at which said rolls are driven may be varied in accordance with the design desired. A greater or lesser speed willso effect the application of the coloring material as to alter the appearance of the design created thereby and thus different designs may be obtained by diii'erent speeds of rotation of' the brushing roll 16 relative to the speed of the paper passing thereabout..

A quantity of coloring material or paint 19 is carried between the respective brushing rolls 16 and coloring rol-ls v18, which rolls are in contact and caused to rotate inthe direction indicated by the arrows. The color-- ing material or paint 19 is thus applied -in a very thin coating, by reason of the close contact that the rolls 16 and 18 have with the surfaces of the rolls 16, and carried thereby into contact with both sides of the paper sheet 10. Whereas the apparatus is herein illustrated as showing a pair of brushing rolls applied to opposite sides of the paper, if it is desired to treat only on'e surface of the paper one of the rolls 16 may be eliminated so ar as lefectlve or coloring contact with the aper is concerned, whereb either one or oth sides of the paper may e treated either with the same color and design or with different colors and designs, depending upon the speed of the respective brushing rolls and the particular color used thereon.

As illustrated in Fig. 2, the surfaces of the brushing rolls 16 are very slightly tool marked to provide ridges and grooves running parallel with each other about the surface thereof. Other designs may be obtained by varying the slight markings of the surface such as scrolls, wavy lines or the like. The slightl marking of the surface of each of the brushing rolls, coupled with the speed of the rolls with respect to the paper passing thereabout has the effect of streaking the colorinw material over the surface of the paper, as i lustrated in Figs. 3 and 4. This streaked effeet gives the appearance, in some examples, of the grain of wood, bark or the like, or may give a different effect, depending upon the colors used, the speed of the rolls, and the design of the markings. The general effect thereof may be further altered by slightly embossing the paper, as shown in Fig. 4.

From the foregoing it will be understood that not only can an effective design be obtained in avery simple and inexpensive manner, but the possibilities of different designs and appearances which may be created are unlimited.

Whereas it has above been mentioned that the rolls operated at a greater speed t-han the paper, the same effect and process may be employed wherein commercially practical, by operating the paper at a greater speed than the rolls.A In other words, the effect is obtained by varying the relative speed between the rolls and the paper. i

Wherein the paper is embossed so as to be provided with elevations and depressions as above described, it will be apparent that the brushing roll or rolls with the coloring matter thinly applied to the surface thereof will engage only the elevations on the embossed paper and not the depressions, whereby the brushing roll will streak the coloring material over the elevations of. the embossed surface while leaving the depressions thereof free from such coloring material.

The invention claimed is:

The process of decorating paper, consisting in passing the paper about a brushing roll having a tool marked surface, thinly applying a coloring material to said roll so as to cause said roll to apply said material to the surface of the paper, and operating said roll at a greater speed than the paper passing thereabout for causing t-he tool marked rolll to straek the coloring material over the surface thereof.

2. The process of decorating paper, consisting in passing the paper about a brushing roll having a tool marked cylindrical surface,

thinly applying coloring material to said roll, sov as to cause said roll to apply said material to thesurface of the paper, and varying the relative speeds of the paper and roll for obtaining different designs formed by the streaking of the coloring material ovei` the surface of the paper by said tool marks at different speeds.

3. The process of decorating paper, consisting in forming a slightly embossed design therein, passing the slightly embossed paper about a brushing roll having a tool marked cylindrical surface, thinly applying a coloring material to said roll so as to cause said roll to apply said material to thel slight ele,-

4. An apparatus for decorating paper in` cluding a coloring roll having a cylindrical surface, about which the paper is adapted to be passed in contact therewith, a pluralityof tool marks formed on the surface of said roll for engagement with the paper, means for applying a thin coat of coloring material to the surface of said roll, and means for operating said roll ata greater speed than the paper passing thereabout for causing said tool marks to streak the coloring material thereover.

5. The process of decorating paper, consisting in forming a slightly embossed design thereon, passing the slightly embossed paper about a brushing roll having a tool marked surface, and thinly applying a coloring material to said roll so as to cause said roll to apply said material to the embossed surface of the paper with markings caused by the tool marks the roll while leaving the depressions thereof free from such coloring material.

In witness whereof, I have hereunto affixed my signature.

A HARRY M. ROSS.
