PAPER-MAKING.
SPECIFICATION forming part of Letters Patent'No. 704,572, dated July 15, 1902.
Application filed November 20, 1901.. Serial No. 82,968. (No specimens.)
To aZZ whom it may concern:
Be it known that 1, ANDREW OUTERSON, a citizen of the United States,residing at Windsor Looks, in the countyof Hartford and State of Connecticut,have invented certain new and useful Improvements in Paper-Making, of which the following is a full, clear, and exact description.
The object of the invention is to improve the quality of paper, particularly the finished surface, and to efiectually cover up what is known as the wire side of the paper.
There are many different methods of making paper in use at the present time; but my invention has particular reference to paper made on Fourdrinier machines and does not concern itself with papers made by other processes.
After a sheet of pulp has been worked by various steps into a marketable product it is found that the side which has rested on the wire is roughened or uneven and not in the best possible condition for use. it is particularly noticeable that this, what may be termed wire side, of the paper, will not take nearly so good and clear an impression from the type as the opposite side, and it is customary with all printers to avoid using the wire side for the impression, if possible, and it is not alone in printing that it is objectionable to use the wire side of the paper, but in view of all this it has been customary in making paper on Fourdrinier machines to finish the wire side of the paper and not in any way conceal it.
By my invention I am enabled to produce paper from a Fourdrinier machine which when finished presents equally perfect surfaces.
The figure of the drawing represents a diagrammatic view of an apparatus embodying my invention.
In carrying out my invention I make use of two Fourdrinier machines, as indicated at A and B, with their delivery ends setopposite one another. The Fourdrinier wires are denoted at A B, passing around the customary idler-rolls and over suction-boxes a b and couch-rolls 1 2, these wires moving in the direction of the arrows.
In printing C D denote the points at which the pulp is flooded onto the wires.
E F denote the felts,which cooperate with the wires A B, respectively, and remove the pulp from the wires. The felt E is carried around the idler-pulleys, moving in the direction of the arrows and passing around the couch-roll 3, which is set directly over each roll 1 of the Fourdrinier machine A, return- I between the rolls 1 3 it picks up the pulp.
from the wire A and as the felt F passes between the rolls 4 2 it picks up the pulp from the wire B. In both cases it is evident that the wire side of the pulp is away from the felt. The felt E now travels about the roll 3 and the felt F passes onto the roll 3 on the top of the felt E, thus uniting the wire sides of the two sheets of pulp. As the pulp travels along between the felts E F and through the baby-rolls 5 6 the two sheets are pressedtogether and thoroughly united,and as it passes between the rolls 7 8 it is subjected to a still greater pressure, which further effects the desired result. Upon passing through between the rolls 7 8 the felt F leaves the sheet of pulp and travels around, as indicated. The felt E carries the sheet of pulp to another part of the machine, where it delivers it for further operations. It is advisable in order to make the adhesion of these two sheets of paper as they come from their respective wires more certain that their wire sides shall be sprayed with water, and I have indicated at G what is intended to represent a suitable apparatus for accomplishing this result. It is clearly evident from this arrangement that I am enabled to produce a Fourdrinier-made paper on which the wire sides shall be in the center of the In the opsheet and the two surfaces can be finished sheets with their Wire sides together to a car with an equal degree of perfection, so that rier, spraying the sheets as they are deliveither one of them will receive with equally eredto the carrier, passingthe sheets to prir 5 good results any impressions, either in print mary pressure-rolls for uniting the wire sides 5 ing or otherwise, which are given them. of the sheets, and finally passing the united I claim as my invention-- sheets to secondary pressure-rolls to further I The herein-describedmethod ofmaking solidify and unite into a single sheet. 7 {paper with both sides having the same de- 7 gree of finish, consisting of forming separate ANDREW OUTERSON' 1o sheets on Fourdrinier machines arranged ad- Witnesses:
