METHOD FOR HANDLING FRESHLY PRINTED PAPER IN ROLL FORM Original Filed May 19, 1930 2 Sheets-Sheet 2 Patented July 2, 1935 ENT oFFicE METHQD FOR HANDLING FRESHLY PRINTER PAPER IN RULE, IFQDIEEM Walter K. Miller, Ila Grange, lIllL, assignor to Shellmar Products (Company, Chicago, Ill... a corporation of Delaware Application Mayliil, I930). Serial No. 453,653 Renewed April 2%, 193 1- 2 (Claims.

ing establishment and considerable labor in the handling of the paper in connection with this drying process. The object of the present invention is to provide a method which'permits the drying of the freshly printed paper in roll form so that the freshly printed paper, in roll form, can be readily handled and will occupy a small space while drying.

In accordance with the present method the freshly printed paper is rolled with a backing sheet provided with raised portions at intervals on the sheet where no printing occurs on the sheet, with the result that as the printed paper is rolled the freshly printed matteris spaced from the backing sheet and permitted to dry whilethe paper is in roll form.

The invention further consistsin the several features hereinafter setforth and more particu-.

larly defined by claims at the conclusion hereof.

In the drawings Fig. 1 is a side elevation View of apparatus used in carrying out the method embodying the invention;

Fig. 2' is a detail sectional view through a part of the rolled sheet showing it flattened and taken along the line 22 of Fig. 3;

Fig. 3 is a plan view of a portion of the sheet that has been flattened from the roll to illustrate I the method embodying the invention.

Referring to Fig. 1, the apparatus for carrying out the-invention includes a frame 5 provided with a receiving roll 6 whose shartl is jou'rnalled' in suitable bearings 8'on the frame and carries a plilley 9 connected by a belt ID to a pulley ll power, not shown, the belt being tensioned in known manner by a roller 13 mounted on a swinging frame 14 from a fix'ed support IS.

The freshly printed. paper I6 is led. from the printing machines-over a guide roller l'l carried by brackets I8 on the framei and, down to the receiving roll 6 upon which it is wound. As the printed paper isbeing wound on this roll a backing sheet l9 from a supplyroll 20 of the same is led from its supporting roll 2| over guide rollers on a shaft l2 driven by any suitable source of.

(on. lill tt) 22, 2t? and 2 3 down to the receiving roll 6 sothat both the printed paper it and the backing sheet 89 are rolled together on the receiving roll, the guide rolls 245 and [I'll being spaced apart so that a space 25 is provided between the paper and the back- 5 ing sheet just before the two come together on the receiving, roll. In this space I previously mount an air supply'pipe or header 26 provided with a plurality of small openings 2'0, one of which is shown, said openings being spaced apart 10 so as to provide for a multiplicity of air jets being projected between the two sheets of the roll as they come together on the receiving roll.

Referring to Figs. 2 and 3, it will be noted that the backing sheet. 09 is provided at spaced inter- 55 vals with strips 2%, these strips 2% facing the printed sheet [Iii as the two sheets come together on the receiving roll and being located on the backing sheet at points spaced from the freshly v printed matter 29 on the printed sheet it. These strips 28 by reason of their thickness provide elevations on the face of the main body of the backing strip is and are previously formed by securing strips of paper to the main body of the backing sheet it bysuitable adhesive, though they may be formed'in other ways in order to provide raised portions on the backing sheet at spaced points in order to spacethe freshly printed material on the face of the sheet it away from the opposing face of the main body of the backing sheet it; "The result is that when the two sheets are brought togetherand rolled on the receiving roll. t that spaces 30 are provided between the printed sheet and the backing sheet at those points where the freshly printed matter on the printed sheet occurs, with. the result that an air space is provided which permits ready drying-of the printed matter without danger ofsmearing the ink on to the backing sheet and ruining the printed matter and the printed sheet and the 40 backing sheet may thus be expeditiously rolled together as the printed matter comes from the printing machine.

In order to increase the effect of these air spaces wherethe printed matter occurs on the sheet the air from the jets 21 is also directed into the spaces 30 between the sheets as the sheets. come together for the purpose of bulging the sheets as they are rolled together as Well as having some drying eifect;with the result that the freshly printedpaper may be readily and expeditiously handled and dried in roll form.

The backing sheet 19 with the strips 28 may be formed in various ways but for the purpose of this application I have shown such sheet as previously formed for use in connection with the printed paper.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts or to all the steps of the method except insofar as such limitations are included in the claims.

What I claim as my invention is:

1. The method which comprises printing a continuous web of paper along transversely spaced portions whereby the space between saidportions is not provided with printing, and simultaneously rolling the freshly printed paper together with a continuous backing sheet provided with longitudinally extending spaced projections aooasev corresponding in position to the position of the unprinted portions of said web, whereby when rolled said printed portions alternate with said raised portions transversely of said roll.

2. i The method which comprises printing a continuous web of material along transversely spaced portions, whereby to provide spaces between the printed portions which are not printed, and simultaneously rolling the freshly printed paper together with longitudinally extending bands corresponding in position to the position of the unprinted spaces of said web of material, whereby when rolled said printed portions alternate with said bands transversely of said roll.
