Description

Feb. 16, 1932. E, c, FRAflco sE 1,845,260
METHOD OF PRINTING AND WAXING PAPER Filed July 29, 1929 INVENTOR By [d/M/W K/W/Im/x Patented Feb. 16, 1932 UNITED STATES PATENT OFFICE EDWARD C. FRANCOISE, OF KALAMAZOO, MICHIGAN, ASSIGNOR T KALAMAZOO VEGETABLE PARCHMEN'I' COMPANY, OF KALAMAZOO, MICHIGAN METHOD OF PRINTING ANDWAXING PAPER Application filed July 29, 192-9. Serial No. 382,046.
The main objects of this invention are:
First, to provide an improved method for preventing offset and waxing printed papers which permits of very large production.
Second, toprovide an improved method of preventing offsetting and waxing papers which permits winding very quickly after printing, thereby avoiding the necessity for long drying reaches between the print-ing and winding points.
Objects pertaining to details and economies of my improved method will definitely appear from the description to follow. The invention is defined in the claims.
The manner of carrying out my improved method is clearly illustrated in the accompanying drawings in which:
Fig. 1 is a diagrammatic view of a printing and waxing apparatus employed by me and illustrating the steps of my process.
Fig. 2 is an enlarged fragmentary section through the offset wax applying and chilling means.
In Fig. 1 I illustrate diagrammatically the reverse or unprinted side of the web of paper 9 as it leaves the printing cylinders. A wiper 10 is provided i' or uniformly distributing the 40 para-flin on the roller 8 and removing excess. At the rear of the paraflln applying roller is a chilling roller 11 contacting with the coated side of the paper, this roller being mounted to permit the circulation of a cooling medium therethrough. I
After passing the chilling rollerthe paper is wound into the roll 3 and permitted to dry, any oftset which occurs being upon the paraflined side of the paper. After the ink is dry the paper is passed through the coating apparatus 4 which consists of a tank for liquid paraffin and a pair of rollers 12. The liquid paraflin as the web is passed through the tank melts and removes the ofl'set preventing paraflin and at the same time coats the web on both side.
From the coating apparatus the web is preferably passed immediately into a chilling aparatus 5 consisting of a tank filled with cold water, and thence to a suitable moisture removing apparatus not illustrated.
My improved method results in very substantial economy. It results in a great saving in the make-ready, that is, it is notnecessary to exercise great care in the makeready to avoid conditions which in ordinary practice would result in objectionable oflset. Further, my improved method. renders it practical to satisfactorily use lower grades of ink than is possible under the old methods.
The speed of the printing maybe very sub-' stantially increased and space economized, as it is not necessary to provide long reaches for drying the ink.
A further advantage is that less skill is required on the part of the printers and workmen.
I have illustrated my method mainly in conventional form and have not attempted to set forth various modifications and adaptations which might be desirable for particular installations. It is believed, however, that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
Having thus described my invention whatis dissolved and a coating of paraffin applied to both sides of the web, and subjecting to a chilling medium.
2. The method of printing and waxing paper consisting of printing a web of paper, applying a coating of liquid paraffin to the reverse side of the web, passing the paraflined side over a cooling roller, winding and permitting the ink to dry, and unwinding and one side. applying a coating of paraflin to the other side, subjecting the paraffin to a cooling medium and rolling the paper upon itself whereby the printed surface is brought into contact with the paraflined surface. and after the ink is dry unwinding and passing the paper through a molten paraffin bath whereby the offset preventing paraffin is removed and the paper coated on both sides, and subjecting to a water bath to chill the parafiin.
4.. The method of printing and waxing paper consisting of printing a web of paper on one side. applying a coating of parafiin to the other side, subjecting the paraffin to a cooling medium and rolling the paper upon itself whereby the printed surface is brought into contact with the paraffined surface, and after the ink is dry unwinding and passing the paper through a molten parafiin bath whereby the offset preventing paraflin is removed and the paper coated on both sides.
5. The method of printing and waxing paper consisting of printing one side, applying a coating of liquid wax to the opposite side, passing the waxed side over a cooling medium, winding and permitting the ink to dry, and unwinding and passing through a bath of liquid wax whereby the wax previously applied is liquefied and another coating of wax applied.
6. The method of printing and waxing paper consisting of printing one side, applying a coating of liquid wax to the other side, rolling the paper upon itself and permitting the ink to dry, and thereafter removing the ofiset preventing wax by a liquefying medium.
7. The method of printing and waxing paper consisting of printing, applying a coating of liquid wax to the opposite side, winding, and after the ink is dry unwinding and passing through a bath of hot liquid wax wherehand.
