2 Claims.
This invention relatesto a method of coating paper for use as decoration material and more particularly to paper coated with mica flakes or other flaky material which affords a high degree of scattered reflection making for maximum brilliance.
According to this invention the paper is first creped to produce alternate ridges and valleys and glistening flakes are then attached to the ridges by a cementitious coating applied to the paper, the flakes occupying different angular positions relatively to the plane of the paper because of the irregularity of the paper produced by the creping, whereby the amount of light reflected to any point of view varies widely among the different flakes depending upon their different degrees of angularity with respect to the particular point of view.
The dimensions of at least some of the flakes are preferably greater than the distance between successive ridges of the creped paper so that they bridge the valleys, it being understood that those flakes which do bridge the valleys occupy different angular positions relatively to the plane of the paper because of the irregularity in the height of successive ridges of creped paper. However, the dimensions of at least some of the flakes may be less than the distances between successive ridges and/or flakes that are large enough to bridge the ridges may be deposited upon the paper so that they do not actually do so, thereby afiordlng a higher degree of angularity with respect to the plane of the paper.
Various adhesives may be employed for anchoring the flakes to the paper, as for example, one of the well-known plasticized nitrocellulose lacquers or a rubber cement comprising approximately one and one-half pounds of milled rubber to one gallon of gasoline with a small amount of anti-oxidant.
After the paper is creped, coatedwith flakes and dried, it may be corrugated transversely of the creping ridges. This not only accentuates the difference in degree of angularity of the re spective flakes but it also softens the product, making it more adaptable to draping and other uses. The difference in degree of angularity may also be accentuated, either with or without corrugating the paper, by stretching the coated paper transversely of the wrinkles to widen the aforesaid valleys and reduce the height of the wrinkles. If the paper be stretched in this way it is preferably done before the cement has completely dried, thereby to reduce the tendency of the flakes to become detached in the stretch- I ing operation.
For the purpose of illustration typical embodiments of the invention are shown in the accompanying drawing in which- 5 Fig. 1 is a diagram of apparatus for practicing the aforesaid method;
Fig. 2 is a section on line 2-2 of Fig. 1;
Fig. 31s a face view of the uncorrugated product;
Fig. 4 is a similar view of the product after being corrugated; and
Fig. 5 is a similar view of being stretched.
The apparatus for treating paper as above de- 15 scribed is illustrated in Fig. 1 as comprising a roll I of paper, such as tissue paper suitable for creping, a creping drum 2, a pan 3 for creping solution, a roll 4 for applying the creping solution to the paper I as it contacts with the drum 2O 2, a doctor blade 5 for creping the paper, a drying drum 6, a trough I containing an adhesive solution which is applied to the paper I through a slit 8 in the bottom of the trough while the paper is passing over the roll 9, a cham- 25 her ill in which the flakes are applied to the paper, an oscillating sieve-like container H for sifting the flakes upon the paper, rotating beaters l2 for shaking oh the flakes which do not adhere to the paper, a drying chamber l3 through 30 which the paper passes back and forth over rollers H, a pair of corrugating rollers I 5 and It for corrugating the coated paper after it emerges from the drying chamber and a take-up roll IT for the finished product. As illustrated in Fig. 35 2 the corrugating rolls l5 and i6 have complemental circumferential ridges, with suflicient clearance between the ridges so as not to pinch the paper tightly as it passes between the rollers.
As illustrated in Fig. 3 the coated paper is characterized in that the flakes I8 occupy different angular positions with respect to the plane of the paper, this being indicated in the figure by different degrees of shading on the respective flakes. After the paper has been corrugated as indicated by the lines IS in Fig. 4 the paper is not only softer and more adaptable to draping purposes but the difference in degree of angularity of the respective flakes is accentuated. After the paper has been stretched, as indicated in Fig. 5 by a greater distance between the creping lines 20, the angularity of the flakes-is still further accentuated.
It has been proposed to apply glistening flakes to uncreped paper but this does not afford a the product after comparable degree of light scattering and brilliance over a wide range of points of view because the angularity of the reflecting surfaces of the flakes does not vary widely from the plane of the paper. Furthermore the slight degree of angularlty of the flakes is still further reduced when the paper is stacked or rolled. According to this invention there is little of this flattening tendency and the small degree of flattening which does result from stacking or rolling is more than counteracted when the crepe paper is subsequently pulled out slightly as is customary in the regular decorating technique.
It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
I claim:
1. The method of coating paper which comprises creping the paper to produce alternate ridges and valleys, applying adhesive to the crepe paper, coating the paper with glistening flakes large enough substantially to bridge the aforesaid valleys, and then stretching the paper transversely of the aforesaid ridges to widen the valleys and thereby accentuate the difference in degree of angularity of the respective flakes with respect; to the plane of the paper.
2. The method of coating paper which com prises creping the paper to produce alternate ridges and valleys, applying adhesive to the crests of the ridges, coating the paper with glistening flakes large enough substantially to bridge the aforesaid valleys, corrugating the coated paper transversely of the aforesaid ridges, and stretching the paper transversely of the ridges to accentuate the difference in degree of angularity of the respective flakes with respect to the plane of the paper.
BENJAMIN ASNES.
