Patented Dec. 10, 1929 UNITED STATES PATENT OFFICE HENRY A. WISE woon, or m, YORK, 1v. r nssieivon 'ro woon NEWSPAPER m- CHINERY CORPORATION, OF NEW YORK, N. Y., A. CORPORATION OF VIRGINIA METHOD OF PREPARING PAPER ROLLS FOR THE WEB CHANGE Application filed August 27, 1927, Serial No. 215,934. Renewed May 14, 1929.
This invention relates to the preliminary preparation of the leading end of a fresh web roll for the web change operation.
The principal object of the inventionis to manipulate the pointed leading ends of the web roll for the purpose of stlfi'ening the points and reducing the tendency to tear when the paster is made. Other features of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which Fig. 1 is an end view of a reel for the web rolls with the parts shown in position just before splicing; Y
t Fig. 2 is a side elevation of two fresh rolls as they appear in the machine, with the machine and running roll omitted;
Fig. 3 is an enlarged detail view of the end of the paper on the roll; and
Figs. 4 and 5 are views showing two steps of folding the paper to strengthen one of the points thereof.
In the splicing of a new paper roll to the running web of a printing press, paste isapplied to the new roll on the surface thereof at the leading end so that the end will attach itself readily to the web coming from the expiringroll." The end of the paper on the fresh web roll is cut or torn usually so Y the tendency of'the paper to tear at the time.
as to form two points 10 in advance of the rest of the web across the same. These points are rather sharp and tendto tear when the paster is made, on account of their shape.
For the purpose of strengthening these points I fold back each point 10'onthe web along an inclined line 11 as shown in Fig. 4 to form a fold 10% Then I fold the corner 12 thus formed along an oppositely inclined line 14, forming a fold 13 overlapping the end of the folded point 10. These folds are bent over as indicated in Figs. 4 and 5 and creased at their edges along the lines 11 and 14 so as to stiffen this point and thus reduce the paster is made. For the purpose of makin the paper at its ends stick to the body of t e roll I apply underneath these folded ends a layer of p tic, not permanently adhesive, material, as grease.- In this way the ends wlll be held against the roll while it is rotating preparatory to splicing. Yet no resistance will be present to prevent the end being taken off by the running web.
The paste is applied in substantially the usual pattern as indicated at 15 on the outer side of the web. Itis to be noted that the paste is discontinued along areas 16 where the margins of the printing newspapers come and. also where the belt 17 or equivalent roll propelling mechanism engages the roll.
The operation of performing the paster is accomplished in any of the usual ways. It will be seen that the points of the web formed as shown in Fig. 5 are of two or three thicknesses so that they are not likely to tear in the pasting operation. These folds are on these respects, but what I do claim is 1. The method of preparing a fresh paper Therefore, I do not wish to be limited roll for splicing to a running web, which comprises the. cutting of the end of the web to an outline in which points are formed and then bending over said points inwardly on the under side.
2. The method of preparing the leading.
end of the web on a paper roll for splicing which consists in preparing it with points projecting, bending each point on an inclined line so that the point will come within the area of the paper and so that it will leave a point at the edge thereof. I
3. The method. of preparing the leading end of the web on a paper roll for splicing which consists-in preparing it with points projecting, bending each point on an inclined line so that the point will come within the area of the paper and so that it will leave a point at the edge thereof, and then bending over the last named point to leave three thicknesses of paper throughout part of the area under the surface of the leading end.
4. The method of preparing the web on a paper roll for splicing, which consists in providing the leading end with points, bending each point underneath on an inclined line so that it will leave a point at the edge thereof,
then bending over the last named point to leave three thicknesses of paper under the surface of the leading end, and applying paste along the edges of the points on the outside.
5. The method of preparing a fresh paper roll for splicing to a running web, which comprises bending over the points at the end of the web, and applying a moist plastic substance, without permanent adhesive properties, to the under side of the points to hold them down on the roll temporarily.
6. As an article of manufacture, a paper roll having the leading end of the web in the form of points, said points being turned underneath the paper in two thicknesses and temporarily secured to the surface of the roll by grease, and having paste on the opposite or outer surfaces along the edges thereof.
7. The method of preparing a fresh paper roll for splicing to a running web, which comprises the cutting of the end of the web to an outline in which one or more points are formed and plicating said points by additional thicknesses of paper.
In testimony whereof I have hereunto aifixed my signature.
