MANIFOLD PAPER AND PROCESS OF PRODUCING TI-EE'SAMEQ Specification of Letters Patent.

Patented Nov. 19, 1907.'

Application filed August 8.190s. Serial No. 329.702.

T 0 all whom it may concern:

.Be it known that I, ERNEST E. Lmroor, of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Manifold Paper and Processes of Producing the Same, whereof the following is a specification, reference being had to the accompanying drawings.

It isthe'object of my invention to provide manifold or impression aper, the impression surfaceof which manifiists a trade mark or other symbolo'f any desired character, which 1s local to said coating, and, to provide a process whereby the cost of such marking is rendered negligible.

The marking above-contemplated is formed and completed exclusively in the impression coating of the paper, and is manifested by contiguous portions of the surface of said coating being of different luster or reflective capacity, because of difference in smoothness. .Such aper may be made with all of the regions 0 theimpression coating of equal "capacity to, transfer an impression, regardlesstof their different reflective capacity, and, all of said regions maybe of equal opacity.

As hereinafter described, the essential characteristic of my improv'edprocess is the subjection of different regions of the impression coating to different temperatures before the coating is finally set or hardened and, as

hereinafter described, a selected region of the impression coating is subjected to a higher temperature than the other regions thereof, after the paper has been provided with a coating of uniform temperature.

, My invention comprises the various novel features of rocedure hereinafter more definitely speci ed.

In the-drawings, Figure I, is a diagrammatic view showing the relative arrangement of certain machine elements which may be conveniently em lo'yed in the conduct of my process; I view of a we 1 of the marking crosssection in Fig. I.

A machine which may be conveniently utilized in a preferred process of manufacturing said paper, com rises a pair of rollers 1 and 2, between whic a web of paper 3, is directed. The upper one ofsaid rollers 1, m ay be the roller by which the coating of impresroller shown in sion material is deposited on said web. The

coated web 3, then asses beneath the marking roller 5, the wal of which, as indicated in Fig. 11, comprises portions 6, which are re Fi I is a fragmentary sectional.

ter with the recessed portions 6, of said cessed with respect to the outer perimeter of the cylinder, and portions 7, which are flush with said perimeter. Said roller 5, is convenientlysupplied through an axial opening 8, with a fluid, for instance steam, whereby it may be maintained at any desired temperature. Saidpaper then passes over a series of pipes 9, or other receptacle for a fluid, for instance steam, whereby the same is maintained at any desired temperature. Said paper then passes between the feed rollers 11 and 12, and over the ledger blade 13, which cooperates with the rotary blade 14, to sever the web in sheets 15, which are deposited in the holder 16. s

, With the arrangement above contemplated, the paper 3, passes from the rollers 1 and 2, with a coating of heated impression material, the temperature of said coating be ing uniform throughout its extent. However, when passing beneath the roller 5, the e selected regions of the impression coating which register with the high portions 7, of the roller 5, are subjected" to a higher temperature than the other regions which re isroller so that the surface of the coating where its temperature is raised is disturbed and is rendered of different reflective capacity from that of the surface which is not thus reheated. If the coating comes directly in contact with the marking roller 5, and is then permitted to cool rapidly, the surface has a stippled or mottled effect, as distinguished from the portions of said coating which have not come in contact with the marking roller, which have a uniform reflective effect. Moreover, the resulting effects of the reheating aforesaid, with res ect to the finished article, may be modifier by variation in the length of time during which the paper is allowed to attain its normal temperature. That is to say, different effects may be produced by varying the temperature of the coating as it passes from the marking roller to the place of. discharge from the machine, and such variations may be effected by independently controlling the admission of fluid to said pipes 9.

The impression. paper which has been subjected to the reheating process above described is not only characterized by con- 'trasting surfaces in different regions, but

such regions are separated by distinctive lines which are manifested by the coating being throughout the extent of said lines of different opacity from the adjoining regions of said coating, for instance, impression sheets madeby a machine arranged as in Fig. I

- have lines separating the regions which rgister with the recesses 6, from the regions which register With the high portions 7, of

. the cylinder 5, and said lines produced by the forward edges of the high portions 7, are less opa ne than the'lines produced by the rear- War edges of said portions. 1

I do not desire to limit myself tothe 'precise procedure above described, as typical of my invention.
