EMIL POEL, OF AUSTIN, PENNSYLVANIA.

MACHINE FOR COATING, COLORING, OR OTHERWISE T REATING PAPER.

Application filed April 28, 1924. Serial No. 709,076.

To all whom it may concern:

Be it known that I, EMIL Penn, a citizen of the United States, residing at Austin, in the county of Potter and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Coating, Colorin or Otherwise Treating- Paper, of which t e following is a specification.

My invention relates to machines for coating, coloring or otherwise treating aper and similar material, and the particular object of my invention is toprovide means, whereby various substances or colors can be applied to the material treated in one operation. In the case of coloring paper, the colors may be so applied that at their line of contact they will to some extent mix so as to produce a composite color or a rambow effect. For a full understanding of my invention, I refer to the annexed drawing in which I have shown by way of illustration in a bodiment of my invention, Fig. 1 being a side elevation of the apparatus, showing the relative position of the various parts entering into Fig. 2 is a plan view on an enlarged scale of the trough containing the colors or other substances to be applled to the material to be treated; Fig. 3 is a sectional view of the trough to show the method of filling the same with various colors; Fig. 4 is a detail View showing a color applying roll with a pad bearing against the same.

The machine as shown in Fig. 1 comprises a cast-iron frame 1 wherein are rotatably journalled two

large rollers

2 and 3 adapted to rotate in the directions indicated by the arrows. With each of these rollers cooperates a smaller roller 4 and 5 respectively also rotatably journalled in movable bearings (not shown) allowing the said smaller Tellers to'be moved with any desired pressure against their corresponding larger roller. The web of paper or?- other material to be treated is wound on a reel 6 and is conducted therefrom over the guide rolls 7, 8, 9, 10, 11 and under 12 to a reel 13 on which the treated or colored paper, or other material is wound. Between the guide rolls 8 and 9 is interposed a drying drum 14 around which the web of material is conducted on its way to the rollers 4 and 5.

The device for applying the treating substance, such as color, to the paper, comprises a trough 15 of a length corresponding to diagrammatic way one 6111- the construction of a machine,

the length of the rollers 2 and 4, which trough, according to the number of colors to be applied to the web of: paper, or other material, is divided into a corresponding number of compartments (1, b, c, d, e, f, g, h, i, 7', etc., as shown in Fig. 2. In the trough 15, in bearings notshown, is rotatably journalled a roller 16 provided with projecting circular disks of a width corresponding to the width of the said compartments, and arranged to dip into the color contained in the said compartments. In each of the said compartments is preferably provided a block 17 of felt or any other suitable material immersed in the color and in such a position relative to the said disks as to continuously apply thereto the required amount of color (see Fig. 4). The blocks 17 are held by resilient arms 18 reniovably secured to the bottom of the trough 15. From the disks on roller 16 the colors are transmitted to the web of paper N, or other material, by means of

rotatableplain rollers

19, 20 and 21, rotating in the direction shown by the arrows. On these rollers, 19, 20 and 21, the colors will spread so as to mix at their lines of contact, and in this manner, composite colors are obtained. For instance, if the compartments formed in the trough 15 successively contain red, yellow and blue, which succession of colors is continuously repeated, then red and yellow in being mixed on the above said transmitting rollers will produce orange, yellow and blue will produce green and blue and red will produce purple, so that the colors when applied to the web of paper N, or other material, will appear as red, orange, yellow, green, blue, purple, after which again comes red, etc. In this way any desired color effects can be obtained. Where, on the other hand, distinct stripes of colors shall be transmitted, then the transmitting

rollers

19, 20 and 21 instead of being plain rollers are made like rollers 16, i. e. with disks of the same width as the disks projecting from roller 16. Instead of the compartments of trough 15 being filled with various colors, the they can, of course, be filled also with one color only, and in that case, stripes of the same color will appear on the web of paper N, or other material, when the color is trans- 'mitted in the manner last described.

In Fig. 3 is shown the arrangement for filling the various compartments in the trough with the various colors. The case of three different colors e. g. red, yellow and blue, such as above described, being assumed, then there will be provided three

tanks

22, 23, 24, one containing the red, the next the yellow and the third the blue color. These colors flow through suitable conduits 25, 26, 27 into the first three compartments a, b and c. As shown in Figs. 2 and 3, compartment (1 is connected through a tube 28 with compartment d, which is the first compartment of the next series, I) is connected through a tube 29 with compartment 0, the second compartment of the next series, while 0 is connected through a tube 30 to compartment 7", the third compartment of the next series.

In the same manner, 01, c and f are connected to compartments g, h and 71 respectively, and so forth, so that the red color, for instance, will flow from compartment a into d, from (i into g from g into 9', and so forth. Yellow flows from 5 into 6, from 6 into it, and so forth, while blue flows from 0 into f, from f into vi, and so forth. In this manner, only one color supply tank is required for each color irrespective of the number of compartments to be filled with the said color. The

tubes

28, 29, 30, etc. are arranged at the bottom of the trough 15. For each color, there is also provided at the other end of the 'trough 15 an overflow to maintain a uniform level. Into the last three compartments there extend

tubes

31, 32, 33 up to a height at which the level shall be kept. These tubes lead to

tanks

34, 35 and 36, which are each provided with a discharge faucet 37 38 and 39 respectively, whereas the

supply tanks

22, 23, 24 are each provided with a cut-off

valve

40, 41 and 42 respectively.

On the end of the roller 16 projecting outside from the trough 15 there is mounted a pulley 43 (Fig. 1) which, by means of a belt 44, is driven by a pulley 45 on the shaft 46, rotatably journalled in bearings not shown, which shaft carries the drying drum 14. On the same shaft is also mounted a sprocket wheel 46, driven by a sprocket chain 47 from the shaft of the roller'2, on which shaft is mounted a sprocket wheel 48. The shaft of the roller 2 is positively driven from a source of power not shown.

In addition to the color applying device, there is shown in Fig. 1 also a coating device for applying melted wax, paratlin, glycerine or the like to the bottom roller 4 when it is desired to give the paper a glazed appearance. The coating device comprises also a trough 49 adapted to contain the coating substance. In this trough there is immersed a rotatable roll 50, which takes up the coating substance and transfers it by means of two other rolls 51 and 52 to the bottom roller 4, whereby it is transmitted to the web of paper N, orother material, as it passes under pressure between the rollers 4 and 2.

In the trough 49 is provided a steam pipe auaeaa 53 to heat the coating substance where it is re uired.

esides the reels 6 and 13, there may be provided two

other reels

54 and 55. From reel 54 a Web of paper, or other material may be conducted over the guide-rolls 56 and 57 between the to roller 5 and roller 3 and then under gui e-roll 58 to the reel 55 as shown by the dash-line N, so as to be coated or otherwise treated, a coating device being shown at 59. Or a web of paper, or other material may be passed from reel 54 following the path of web N first between the rollers 5 and 3, then around 3, as shown by the dash and dot line N through the space between 3 and 2 and over the guiderolls 60 and 7 to the guide-roll 8, then following the path of the web N. In this way, a web of paper or other material may be 1n one operation treated on both sides. I claim as my invention:
