2 Claims. (Cl. 81 19) the side opposed to such areas.
Second, to provide a method of producing parchmentized paper having predetermined areas thereof which simulate watermarking effects.
1 Third, to provide a method of producing such paper which may be practiced at normal parchmentizing speeds and with relatively minor additions to a combined paper machine and parchnientizing apparatus.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
'FIG. 1 is a diagrammatic view of an apparatus which may be used in the practicing of a method of my invention and in producing the product.
FIG. 2 is a conventional plan view of a strip of paper conventionally illustrating the product.
FIG. 3 is a greatly enlarged sectional view on a line corresponding to line 33 of FIG. 2.
It should be understood that while the accompanying drawing is largely diagrammatic it does represent means in their relative relation to each other which may be desirably used in the practice of the method and production of the product of my invention.
In the accompanying drawing 1 represents a paper making machine, 2 guide rollers for the web of paper 3. Between the paper making machine and the parchmentizing of the web it is, in effect, printed with a parchmentizing resist solution, the resisting solution being deposited on the paper in the desired design and spacing.
vIn the accompanying drawing a printing cylinder is indicated at 4. The resist solution is desirably Water with a surface tension reducing agent therein, that is, an agent which reduces the surface tension of the water so that it remains in the film form in which it is deposited on the web and does not contract or form bubbles or spread laterally to a substantial degree.
In the accompanying drawing the web is supported in opposed relation to the printing roller by the roller 5, 6 represents a tank for the resist solution, 7 a feed roller and 8 a transfer roller coacting with the feed roller and the Y printing roller or cylinder 4. At the rear of the printing cylinder and closely adjacent thereto is a parchmentizing apparatus conventionally illustrated as consisting of a tank 9 and the web supporting rollers 10 which are positioned to allow the web to pass through the parchmentizing solution. The parchmentizing solution may be of well known and extensively used type and therefore is not described herein.
After passing through the parchmentizing solution the web is promptly washed and means for doing this are conventionally illustrated as consisting of a tank 10 and guide roller 12, however, it is desired to mention that sprays of water may be conveniently used in the wash ing step. After the washing step the paper is dried, a drier being indicated at 13. The paper is then rolled or 3,076,689 Patented Feb. 5,, 1963 cut into sheets as may be desired, a roll 14 being indihibiting the parchmentizing of such areas with the result that they stand out and are clearly distinguished from the parchmentized portion of the paper designated by the number 16 in FIGS. 2 and 3. The numeral 16 designating the-side'parts opposed to the parts is used to emphasize the fact that the paper is continuously parchmentiz-ed between the area 15 and on the side opposite the areas 15. This permits the use of the paper for pract-icallyranypurpose for which parchmentized paper may be used.
In practice it has been found that while a very considerable number of materials may be used for the resist solution; the following four alcohol-water solutions gave very satisfactory results namely methyl alcohol, ethyl alcohol, n-propyl alcohol and iso-propyl alcohol, the ethyl alcohol being in the percentage of 10.0 to water, methyl alcohol in the percentage of 0.5, iso-propyl alcohol 0.01 and n-propyl alcohol in the percentage of 0.01. As stated, the applicant has found that considerable number of materials may be used to regulate the surface tension of the water. The printing roll may be of the rubber type and is provided with the proper patterns it is desired to reproduce on the paper and spaced as desired.
One advantage of the applicants method is that it adds very little cost to producing parchmentized paper, the major cost being in the production of the printing roll or cylinder. Suitable parchmentizing resist solution may be very economically produced, of course, some attention is required in properly adjusting the printing roll or cylinder and in the preparation of and maintaining the resist solution.
As before stated, there are many resist or parchmentizing retarding solutions that may be used. A water solution treated to lower the surface tension thereof to less than 50 dynes/cm. gets commercially satisfactory results and the four solutions herein'before listed with the concentration indicated are referred to both because of satisfactory results produced and economy and convenience in use. Desirably time lapse between the application of the resist and subjecting to the parchmentizing liquid should be short. A time lapse of two-thirds of a second has proven satisfactory.
One advantage of the method is that it is not necessary to reduce ordinary parchmentizing speeds as it is important to subject the paper with the resist thereon to the parchmentizing step before the resist has penetrated en tirely through the paper. One important feature of the applicants invention is that it secures a watermarking or ornamental effect without destroying the parchmentizing function.
While various apparatus might be used to practice appiicants method applicant has diagrammatically illustrated and described the method in connection with a paper making machine as applicant considers that to be the most practical from the economy angle and it is quite a general practice to parchmentize paper as it is produced. However, it is believed that this disclosure will enable those skilled in the art of paper making and the art of parchmentizing paper to practice my invention as may be desired.
Having thus described the invention, what is claimed as new and is desired to be secured by Letters Patent is:
l. The method of producing parchmentized paper having on one side thereof spaced areas of predetermined spacing and design simulating watermarks and of less depth than the thickness of the paper comprising the steps of translating at parchmentizable speed a web of paper formed of fiber capable of being parchmentized, applying to restricted spaced areas on one side of the web as it is translated films of solution of water and an alcohol of the group consisting of methyl alcohol, ethyl alcohol,
n-propyl alcohol and iso-propyl alcohol in such proportions as to substantially reduce the surface tension of the water,- and before evaporation or substantial penetration of the solution into the. fibers of the web submergingly translating the web with the solution thereon through a parchmentizing solution, and washing and drying the treated web as a continuous operation. 1
- 2. The method of producing parchmentized paper hav-. ing on one side thereof spaced area which simulate-water; marks comprising the steps of translating a web of paper formed of'fiber capable of being parchmentized, applying to one side of the web as itis being translated and' in arepeated predetermined design filmsof a solution of water and an alcohol of the group consisting of methyl alcohol, ethyl alcohol, n-propyl alcohol and iso-propyl alcohol in such proportions as to substantially reduce the surface tension of the Water, and before evaporation or penetration of the solution through the web submergingly translating the web through a parchmentizing solution, and washing the treated web as a continuous operation.
