DUPLICATING ROLL OR SHEET AND PROCESS FOB MAKING SAME.
Specication of Letters Patent.
Patented Aug. 31, 1915.
Application mea December 15, 1914. serial No. 877,369.
To all whom it may concern Be it known that I, ALBERT IsAAcs, a citizen of the United States, and a resident of the city and State of New York, have 1nvented certain new and useful Improvements in Duplicating RollsY or Sheets and Processes for Making Same, of which the following is a specification.
My invention relates to duplicating rolls or sheets for duplicating machines, and to the processes by which same are made, and more particularly to an improved form of roll or sheet which will be lasting in quality and which cannot be easily torn, from which the coating is not easily removed, which will not dry out, and in which the fabric support of the gelatinous material will not leave an imprint on the said material or otherwise injure it when the sheet is rolled up.
The invention consists in the new and improved process by which such a roll or sheet is produced and in the sheet produced by saidprocess, as illustrated by means of the accompanying drawings, andA hereinafter more particularly described.
In the said drawings, Figure 1 is a crosssection of a portion of a duplicating roll or sheet constructed according to my invention in its simplest form; Fig. 2 is a similar cross-section of a modified form; and Fig. 3 is a perspective view of a portion of such a roll or sheet constructed according to my invention.
Heretofore, in order to produce duplicating rolls, a sheet or roll of oil-cloth has been covered on the raw side .with several coats of linseed oil, and after allowing the same to dry thoroughly, a layer of hot gelatinous composition has been applied to the oilcoated side. It has been found, however, that the gelatinous composition dried out and becomes inelastic, renderingr the sheet useless. t In order to overcome this difliculty a different process has been used, consisting in coating the finished side of the oil-cloth with a layer of gelatinous composition. Rolls made by this process were less liable to dry out, but it was found that when the roll was rolled up the threads of the raw side of the cloth would imprint themselves upon the composition, destroying its smooth surface. The present invention comprises a new process and new product eliminating the disadvantages above mentioned.
In carr ing my invention into effect in the modi ication thereof, shown in Fig. 1, I provide a roll or sheet of fabric, adapted to form a support for the duplicating medium, said fabric being designated 11. One side of this fabric is coated with a suitable filler, which may be composed of, for instance, whiting, zinc, oXid, white lead, clays, or other suitable substances which when mixed with a drying oil, such as linseed oil, will serve to coat and fill in the said fabric, the materials used on this side of the fabric being preferably such as will be more or less adhesive to the gelatinous composition to be afterward applled. In the drawing this filler is designated 12. The other side of the fabric 11 is coated with a filler 14:, which may be of a composition substantially similar to the filler 12, except that it is preferably made from such materials as are as far as possible non-adhesive to said gelatinous composition after the same has become set. One purpose of this filler is to prevent the Weave of the fabric from impressing itself upon the duplicating surface, thus roughening the same and making it unfit for use. If desired, the surface of this filler 14 may be calendered so as to. render the same smoother as well as more durable.
It is, of course, immaterial which of the two coatings above referred to is applied first, and they may be applied simultaneously if desired. After the fabric has been coated with the filler 12 it is covered on that side with a gelatinous duplicating composition 13, adapted to receive impressions made upon paper or the like with a suitable duplieating or copying ink, and to transfer such impressions to other sheets of paper or other suitable material. The gelatinous composition, heated to a suitable temperature, is applied so as to form a layer in contact with the filler 12, the heat temporarily softening the oil in the filler and causing the gelatinous composition to adhere.
In the form shown in Fig. 2, I also provide a fabric support, here designated 15, one side of which is coated with a filler 16, analogous to the filler 14 of Fig. 1, which like the filler 14 may if desired be calendared. The other side of the fabric, which is to receive the gelatinous duplicating composition is also coated with a filler 17, analogous to the filler 12 of Fig. 1, although in this case it is not specially desirable that the filler be adhesive to said gelatinous composition, as this filler 17 is coated with a layer 1S of drying oil, or some similar substance, this layer causing the hot or liquid gelatinous duplicating composition designated 19, to adhere to the filler 17 in a manner analogous to that described above.
By the above process, a duplicating roll or sheet, may be produced in which the gelatine composition will not dry out, and in which the threads of the cloth will not imprint themselves upon the face of the gelatinous composition. It is not essential that the duplicating composition employed be a gelatinous composition, as a sheet comprising any composition which may be applied and which will adhere, and which Will serve to receive and transfer impressions, will be Within the spirit and scope of my invention.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:
1. The process of producing a duplicating roll or sheet adapted to be rolled up upon 'itself which consists of coating a fabric With a filler on both sides, and coating one side of said fabric with a gelatinous duplicating composition.
2. The process of producing a. duplicating roll or sheet adapted to be rolled up upon itself which consists of coating a fabric with a filler on both sides, one of said fillers being adhesive to a duplicating composition and coating said adhesive filler with a gelatinous duplicating composition.
3. The process of producing a duplicating roll or sheet adapted to be rolled up upon itself which consists of coatinga fabric with a filler on both sides, one of said fillers being non-adhesive t0 a duplicating composition, and coating the side of said fabric not bearing the non-adhesive filler with a gelatinous duplicating composition.
4. The process of producing a duplicating roll or sheet adapted to be rolled up upon itself Which consists 0f coating a fabric with a filler on both sides, coating one of said fillers with a substance adhesive to a duplicating composition, and coating said adhesive substance with a duplicating gelatinous com position.
5. The process of producing a duplicating roll or sheet adapted to be rolled up upon itself which consists of coating a fabric with a filler on both sides. one of said llers being non-adhesive to a duplicating composition, coating the other of said fillers with a sub stance adhesive to a duplicating composition, and coating said adhesive substance with a gelatinous duplicating composition.
6. The process of producing a duplicating roll or sheet adapted to be rolled up upon itself which consists of coating a fabric with a filler on both sides, one of said fillers being adhesive to a duplicating composition, and the other of said fillers being non-adhesive to a duplicating composition, calendering one of said fillers, and coating the other filler With a layer of gelatinous duplicating composition.
Y 7. The process of producing a duplicating roll or sheet adapted to be rolled up upon itself which consists of coating a fabric with a filler on both sides, calendermg one of said fillers, coating the other of said fillers with a substance adhesive to a duplicating composition, and coating the said adhesive substance with a gelatinous duplicating composition.
8. The process of producing a duplicating roll or sheet adapted to be rolled up upon itself Which consists of coating a fabric with a filler on both sides, and coating one side of said fabric with a heated gelatinous duplicating composition.
