PRINTING PRESS FOR NEWSPAPER wow Filed Oct. 9, 1930 2 Sheets-Sheet 2 rim PRINT/N6 POLL Q) lMP/EESJ/O/VEOLL Patented Apr. 20, 1937 UNITED STATES PATENT 1 OFFICE 19 Claims.

This invention relates to printing presses, and particularly to presses for printing newspapers and the like, and has for its object to provide for perforating the sheets of the newspapers along the lines of fold thereof for the purpose of enabling the reader thereof to effect a convenient refolding of the sheets back to back from an open position of the sheets, and vice versa.

It is a common practice, particularly on trains, street cars and the like, for the reader of a newspaper to unfold and open the sheets of the news paper to a desired page, and then reversely fold the sheets back to back so as to bring a desired inner page into view, the newspaper being then in its original compact form. However, much difficulty is experienced in so opening and then reversely folding the sheets or pages, a considerable amount of close attention, experience and skill being required to open and reversely fold a newspaper into its original flat and compact condition. This is particularly true, where, as is usual, the newspaper has been folded across its middle transverse to the page fold lines of the several sheets of the newspaper, as the intersections of these angular disposed fold lines causes the large flimsy sheets of news print paper to buckle which prevents the quick and convenient refolding of the sheets back to back, and requires special and careful manipulation of the 30 sheets along their fold lines to bring the newspaper into the desired reversely folded and compact form.

In view of the disadvantages above pointed out, it is the prime object of the present invention 35 to provide the several sheets of a newspaper with perforations or weakened portions along the fold lines thereof which will enable the convenient unfolding and reverse folding of the pages in a simple and convenient manner and without 40 danger of the sheets buckling along the fold line.

The perforating may be done at any of a large number of places on the printing press, and in the accompanying drawings I have illustrated 5 means for perforating at different places in the press. V

With these and other objects in view, the present invention. consists in the combination and arrangement of parts as will be hereinafter more 50 fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it of course being understood that changes in the form, proportion, size and minor details may be made, within the scope of the 55 claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Figure 1 is a fragmentary front elevation of a portion of a newspaper printing press showing a pair of formers for folding the paper and equipped with means for perforating the paper along the line of fold between sheets of the prod- Fig. 6 is a side elevation of a former for folding the so-called tabloid newspaper and equipped with means for perforating the same along the fold line.

Figure 7 is an enlarged detail fragmentary sectional view on the line 'l'l of Figure 6.

Figure 8 is a detail view illustrating a newspaper perforated in accordance with the present invention.

Figure 9 is a side elevation of a conventional printing roll such as is employed in the form of the invention illustrated in Figures 1 to 4 inclusive and showing the printing columns extended circumferentially of the roll.

Figure 10 is a side elevation of a conventionalform of printing roll for use in printing the socalled tabloid sheets, such as shown in Figures 5 and 6 of the drawings, the printing columns extending longitudinally of the roll.

In Figures 1 and 2 of the drawings, I designates the usual former commonly employed on newspaper printing presses for folding the print ed paper as it is fed to the former. The print paper is indicated at 2, and this print paper, which has been printed in the usual column formation in the newspaper, is, severed longitudinally by the usual cutting means 3 to divide the paper into two longitudinal strips, each strip of course being a duplicate of the other. The paper of course is fed along by and between a feed or drag roller 4 and presser rolls 5 mounted upon a shaft 6, all of which is common and well known and constitutes no part of the present invention. It will of course. be understood that the former,

shown in Figures 1, 3, 5 and 6 is used in conjunc-,

tion with any common or preferred form of printing mechanism such as will print page sections in columned and spaced newspaper formations on a web of paper, such columned formations being indicated on the paper 2 as shown in Figures 1, 3, 5 and 6, and therefore it has not been deemed necessary to show in the drawings any form of printing mechanism.

In carrying out the present invention, in the form exhibited in Figures 1 and 2 of the drawings, the shaft 6 is provided with a wheel or roller 7, which may be the usual presser roller commonly employed to press the paper against the drag roll 4 at this point, and this presser roller is provided with a series of blades 8 arranged to register with a series of seats or perforations 9 in the drag roller 4, whereby the paper'will be perforated, as will be readily understood by reference to Figure 2 of the drawings, so .as to produce a line of perforations ID in the unprinted central longitudinal space or column of the paper and along which the paper is folded as it passes down along the former l between the usual forming rollers I I and nipping rollers 12. It will of course be understood that after the web of paper has been folded and perforated and passes out from between the nipping rolls l2, it will subsequently be cut transversely into page sections in any common or well known manner, and therefore it has not been deemed necessary to illustrate any means for so cutting the web into sections.

It will of course be understood that several printed webs of paper are superimposed by the printing press and fed across the drag roller 4 and downwardly across the former l and therefore it will be further understood that all of these webs are perforated at the same time so as to produce the effect shown in Figure 8 of the drawings. This perforated line weakens the paper along the fold line and enables the convenient refolding of the newspaper by the reader thereof in the mannerfully set forth in my copending application filed July 3, 1930, Serial No. 465,676, which has eventuated in Patent No. 2,011,572, issued August 20, 1935.

With the provision of perforations or weakened portions along the fold lines of the several sheets of the newspaper, it will be found that with the newspaper in its open condition, as in Fig. 8, and the opposite outer longitudinal edge portions of the newspaper held in the respective hands of the reader, the entire newspaper may be conveniently folded back to back merely by throwing the hands away from the body and inwardly towards one another until the sheets have been folded back to back.

Should the operation of the perforating wheel I produce any cuttings, it is desired to carry off such cuttings by permitting them to fall into the hollow drag roller 4 and to be drawn out of the ends thereof through suitable tubes i3 connected to a suitable source of suction.

The shape of the cutting blades 8 may be varied to produce actual perforations of different shapes, instead of mere slits, all of which willbe understood by reference to my co-pending application hereinbefore referred to.

Instead of perforating the paper as it passes across the drag roller 4, it may be perforated at the place indicated in Figures 3 and 4 of the drawings, wherein l4 designates a shaft, suitably driven in any manner from some moving part of the printing press and provided with a presser wheel I5 bearing upon the unprinted longitudinal central portion of the paper 2 adjacent the lower end of the former I, this presser wheel being provided with suitable blades 16 to perforate the paper, the former I being provided with an opening 11 to accommodate each blade and permit the same to cut the paper. A suitable suction pipe l8 may be connected to the underside of the former at the opening I! so as to carry off whatever cuttings may be produced by the rotating perforating member. The forming rolls II and the nipping rolls i2 of course are present as in Figure 1.

In Figures 5, 6 and 7, there has been shown means for perforating so-called tabloid newspapers, and in these figures there has been shown a former I, a drag roller 4, a shaft 6 carrying presser rolls, or wheels, one of which has been shown at 5, a cutting device 3 to sever the longitudinal print paper into two newspapers, and another cutting device 19 on the shaft 6, for cutting paper into sheets of the tabloid paper. In the tabloid form of paper the columns of each sheet, instead of extending in the direction of the travel of the paper as in Figure 1 of the drawings, extend transversely of the direction of travel, as well indicated in Figures 5 and 6 of the drawings. The cutter 9 cuts the tabloid web so as to sever it along the line designated 20, and thus divide it into two webs, each of which passes downwardly at one side of the former as best shown in Figure 5, and between the usual forming rollers II. The nipping rollers 2| are very much larger than the usual nipping rollers and one of them is provided with a longitudinal series of blades or perforating members 22, and the other nipping roller is provided with a series of seats or perforations 23 to receive the blades, so that as the tabloid webs are fed downwardly by and between the nipping rolls 2|, the tabloid webs will be perforated in parallelism with the printed columns and in the unprinted space, designated 24, along which the tabloid sheet is subsequently folded by any of the well known or preferred forms of folding means. Preferably the nipping roll which is provided with seats or perforating members 23, is hollow and is provided at both ends with suitable tubes 25 connected with a source of suction so as to carry off any cuttings which may be produced by the perforating means.

It will be understood that the cutter IS, in Figures 5 and 6 slits the web longitudinally and thereby divides it into two webs which are acted upon by the former l and the forming rollers H so as to bring the two web portions face to face as they pass between the nipping rollers 2|, and thereafter the two webs are severed transversely to form page sections which are folded by any well known or preferred form of folding means along the unprinted portion 24 in which the perforations have been formed. Inasmuch as cutting and folding mechanisms which act upon the tabloid webs after they pass beyond the nipping rollers are common and well known, it has not been deemed necessary to illustrate such mechanism in the present drawings.
