MEANS FOR FORMING NERVS AND TABLOID SECTIONS FROM A CONTINUOUS WEB.

Application filed June2, 1926. Serial No. 113,135.

livlyinvention relatesto improvements in means for forming news and tabloid sections from a continuous web and has for its object reproduce a web printing press which will produce alternate news and tabloid sections from one former. A further object of my intention is toprovide an in'iprovement in printing presses whereby from one former both' news sections and tabloid sections can be produced, which two sections are automatically assembled in foldedform by the 7 regular assembling and foldingmechanism,

thus saving the laborof manually inserting tabloid sections within news sections, as at present p 'acticed when only one former is in use or when a double former press-is run at full capacity. A further object of my invention is toproduce a tabloid slit-tor attachment which can be applied to various web presses at presentinuse at comparatively slight expense so as to produce from one former 'bothtabloid sections and news sections.

The following is a description of an embodiment of my invention reference being had to the accompanying drawings in which:

Figure 1 is an end elevation of a press showing the "novel features resulting in my improvement Fig. 2 is a View partly in side'elevation and partly in'section on the line 2-2, Fig. 1;

Fig. 8 is a detail'sectional 'viewof a slitting knife on theline 3 3, Fig. 2;

Fig. 4 is a diagrammatic view showing my improvement in connection with a press ideliveringa web of paper and cut and folded sections to a conveyor;

Fig. 5'shows a detail View of a web slit in accordance with my invention; and

Fig. 6 is a perspective view showing tabloid and news sections formed and folded together by a press embodying my invention. 7 Referring more particularly to 'thedrawings 2 isthe delivery end portion of a frame for the operating parts of the press proper. Suitably journaled on thisframe is the usual paper drag roll 4 over which a web of paper 6 passes after it has gone throi'i'gh the printing press proper. This web is a mult1- ply webbeing composed of from two to SIX- teen thicknesses of paper which have been printed upon the cylinders, according as the press is a quadruple, sextuple or octuple. Mounted upon the frame are bearings supporting a shaft 10 carrying the ord nary whose ends are journaled a shaft 26 carrying ai'disk 28 secured thereto so as to rotate therewith. This disk is provided with a knife 30 extending around one half of the periphery thereof. This disk takes the place of the ordinary central trolley and bears upon the" central portion of the paper (3 so asto keep it from buckling. The drag roll t is made in two sections, the sections being spaced apart beneath the center-of the web 6 as at 32, so as to permit the passage of the lnnfe80. The cutting edge of the knife bears against the edge of one of said sections .soas to produce in conjunction therewith a shearingaction'upon the web passing over the'd-rag roll.

The left hand end of theshaft is supported by the'third arm Q lcarried by and fixed to the trolley shaft and between that arm andthe disk is agear 34 whose pitch line 'is'ofsubstantially'the same diameter as the diameter of the disk 28. Meshing with this gear 'is a gear 36mounted upon the shaft of the drag roll'and having its pitch line of substantially the same diameter as the drag roll4,'sothat the disk 28 rotates at substantially the same peripheral speed as the web passing ov-erthe drag roll. The drag roll beingdriven in the ordinary manner, the disk is driven at substantially the same peripheral speed as the drag roll and the knife 30 intermittently cuts a slit 37 in the web,"the"'slit portion corresponding to the length ofa tabloid section and being followed by an nnslitted portion corresponding to the le'ngth of a news section. This intermittently slitted webis'then received by a formerBSin" the crdinaryway and folded upon itself, passing; bet-ween thensual guide and foldingrolls 40 and "42 and being thereafter fed to the well known cutting and folding

cylinders

46, 48 and 50. The cutting cylinder L6 is adjusted in the well known way for what is commonly known as cylinder collect so that it collects and superimposes alternate sections by means of the usual collector pins 52. The cylinder 46 is so adjusted that it collects and carries around a news section so as to superimpose it upon the following tabloid section in the manner in which unslitted sections are now collected, after which the combined sections are carried by the cylinder 48 with its usual'coll-ecting pins 49 and pushers 54 to the well known folding rollers 50 which delivers them to the conveyor distributor 56, which receives them and deposits them upon the conveyor 58, folded together in the form shown in Fig. 6 which shows a news section formed and folded together with a tabloid section 62 out and folded and located within the folded outer sheets.

When it is desired to use the press for ordinary printing without the formation of tabloids, the semi-circular slitting knife 30 is removed whereupon the disk 28 performs the function of the ordinary trolley, although it is positively driven.

The cylinder 48, as is usual, is twice the diameter of the collecting cylinder 46, resulting in the superimposing of the two sections when the collector cylinder pins 52 of the roller 46 are adjusted to collect the news sections thereon.

In operating a press embodying my invention, the multi-ply web of printed paper is supplied to the drag roll 4 in the ordinary manner, and while passing over that roll is intermittently slit by the semi-circular knife, producing the result shown in Fig. 5 with its news sections 60 and tabloid sections 62. The paper then passes over the former 38 and through the guide rolls 40, 42 and then down to the cutting and collecting

rolls

46, 48, the mechanism being so adjusted-that an unslitted portion of the web constituting the regular news page, such as is shown at (30 in Fig. 5, comes first and is collected by the roll 46 and is then followed by a slitted portion or tabloid section 62 upon which it is superimposed whereupon both sections are collected by the cylinder 48 and fed by the pushers 5a to the folding rolls 50, so that when folded the news section comes on the outside of the tabloid section, as shown in Fig. 6. thus producing from a single web of paper a formed and folded section comprising regular news pages having folded within them tabloid sections and doing away with the necessity of separately printing and manually inserting tabloid sections.

As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In a printing press, the combination of a drag roll, a slitting device intermediate of the ends of said drag roll and having a cylindrical surface adapted to constantly ongage the web upon the drag roll and a knife extending around substantially one-half of the. periphery thereof and adapted to intermittently slit the web as it passes over said drag roll.

2. In a printing press, the combination of a drag roll, a slitting device intermediate of the ends of said drag roll and having a cylindrical surface adapted to constantly engage the web upon the drag roll and a knife extending around substantially one-half of the periphery thereof and adapted to intermittently slit the web as it passes over said drag roll, and means for positively driving said cylindrical surface at substantially the same peripheral speed as the drag roll.

3. In a printing press, the combination of a dag roll, a slitting device intermediate of the ends. of said drag roll and having a knife extending around substantially 011ehalf of the periphery thereof and adapted to intermittently slit the web as it passes over said drag roll, said device having on its periphery surfaces constantly bearing upon the surface of the web passing over said drag roll.

4. In a printing press, the combination of a drag roll, a slitting device intermediate of the ends of said drag roll and having a knife extending around substantially one half of the periphery thereof and adapted to intermittently slit the web, said device having on its periphery surfaces bearing upon the surface of the web passing over said d 'ag roll, and means for holding said surfaces in yielding contact with said web and means for driving said surfaces at substantially the same peripheral speed as said roll.

5. In a printing press, the combination of a roll, a. slitting device intern'iediate of the ends of said roll having a semicircular knife extending around part of the periphery thereof and adapted to intermittently slit the web as it passes over said roll, a former for forming the intermittently slit web, and cutting and collecting means adapted to superimpose two alternate sections of said folded web, and means for folding them after being superimposed.

In testimony whereof, I have signed my name to this specification this 1st day of June, 1926.

EARL L. MARTIN.
