WEMSSEMBLING APPARATUS FOR PRINTING PRESSES AND THE Application filed. June 2,

My invention relates to printing presses, and more particularly to folding and web defleeting and guiding mechanism used as an appurtenance thereto, and to an improved method of guiding the webs of paper passing through such printing presses, and has for one of its principal objects to provide mecha: nism by which a comparatively wide web of paper, or a plurality of such'webs placed one upon the other, may be cut or slit into narrower strips and said strips distributed in various ways as it may be desired, and assembled with other strips and cut and folded, in a simple and efiicient manner, as will be hereinafter described. Other objects of the invention will appear from the following description.

The invention consists in the novel arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, certain embodiments of the same being illustrated in the accompanying drawings and described in this specification.

In the accompanying drawings,

Fig. 1 is a diagrammatic view of a folding mechanism showing one embodiment of my invention; and

Fig. 2 is a similar view showing a modification of the same.

In carrying my invention into efiectin the particular embodiment thereof which is shown in Fig. 1 of the accompanying draw ings, I provide formers 11, 11, of the usual or any suitable construction, over which one or more webs of paper maybe passed. In the drawings the formers are shown covered by paper which is passing over the sa.me, the paper being designated 50. Ad acent the upper part of these formers 1s a rod 12 upon which'are swingingly mounted a series of rotating knives. or cutters 13, which are adapted to out the webs passing over said formers into narrower strips, in a manner which will be well understood from an examinat-ion of the drawings. In Fig. 1 of the drawings a series of three wide webs are shown passing over the duplex former, with three cutting knives in operation which sever these wide webs longitudinally into four narrower series of webs, which then proceed down over the formers in the usual manner. Assuming that as shown in Fig. 1 there are three layers or webs of paper passing over the duplex former, it will beseen. that these 1926. Serial .No. 113,199.

. and that these can be disposed oi invarlous ways, by threading the difi'erent layers in different combinations through the various rollers. For instance, the three layers or webs of paper which pass over the left hand half of the duplex former in Fig. 1, will be folded and passed through between the rollers 14 as a six-ply web. From that point it would be possible to pass the whole series of'six webs down between the rollers 16. 17 and 18 (the said series of webs being at this point designated by the reference numeral 54) and then downthrough the cutting cylinders 22 and 23 where the webs are cut into suitable lengths, folded between the rollers 26 by a suitable tucking blade, delivered into the fly delivery 28 and from there to the delivery belt 30, all in a manner which will be well understood. Or if desired, two webs may be deflected to the right after passing between the rollers 16and pass over the roller 32, two more may be deflected after passing between the rollers 17 and pass over the roller 33, and the remaining two may be deflected after passing between the rollers 18 and pass over the roller 34, all these six being then col lected together and assembled with the complementary webs which have passed down from the right hand half of the duplex former, between the rollers 15, 19, 20 and 21, the whole series of 12 narrow webs then passing between the cutting cylinders 24cand 25, folding rollers 27, and into the fly delivery 29 and to the delivery belt 31.

It will be seen that many different combinations may be made and the various webs or layers of associated Webs may be sorted out and assembled in different ways as desired, and that when desired it may be provided whenever necessary that but a small number of layers of paper will pass over any one roller at any considerable angle, so as to avoid the creeping, buckling and wrinkling of the layers one upon another which would otherwise result.

In the modification of the invention shown in Fig. 2 I show formers 11 and knives 13 mounted on a rod 12, as in Fig. 1. I also show rollers 40 and 41 on one side and rollers 42 and 43 on the other side. But in this form .of the invention I provide additional pairs of rollers 44 and 45, as will be seen in the middle portion of Fig. 2. The remainder of the mechanism in Fig. 2 is substantially the same as in Fig. 1.

It will be seen that by the modified arrangement of parts shown in Fig. 2, it is possible to accomplish somewhat different results from those described, in assembling the sheets, which it unnecessary to describe in detail, as the same will be obvious.

The operation of the invention has been already sufiiciently described in what has been said above with regard to its construction,

and the advantages have been to some extentpointed out, and indeed are obvious from an examination of the drawings. I might, however, call attention to the fact that the form of invention shown in Fig. 2 is particularly well adapted to cases where vertical space is limited and a somewhat compressed form of construction is. required, while the form shown in Fig. 1 is better adapted to handling a large number of superimposed webs or layers of paper without slipping, wrinkling or buckling.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is as follows: I

1. In a web assembling apparatus for printing presses and the like. the following elements in combination: a former over which a plurality of webs of paper may pass, means for feeding said webs of paper, a plurality of cutting cylinders for said webs, and meansintermediate said former and said cutting cylinders adapted to separate said webs and separately direct the same with reference to said cutting cylinders.

2 In a web assembling apparatus for prlnt- 'ing presses and the like. the following elements in combination: a former over which a plurality of webs of paper may pass, means for feeding said webs of paper, a pair of cutting cylinders for said webs, and means intermediate said iormer and said cutting cylin der-s adapted to receive the webs from a portion of said former, separate the same and separately direct the same with reference to a web from another portion of said former and with reference to said cutting cylinders, said means comprising a plurality of pa rs of rollers adjacent said former and at varying dis t-ances therefrom, one pair of said rollers being adapted to pass certain of said webs of paper therebet'ween and to permit one of said webs to be deflected laterally therefrom after passing therethrough, a succeeding pair of said rollers being adapted to pass certain of said webs of paper, not including the web previously deflected, therebetween and to permit one of said webs after passing therethroughto be deflected laterally therefrom, and a plurality of rollers located laterally of said pairs of rollers, adapted to receive said deflected webs of paper respectively and direct the same with reference to a web from another part of said former and with reference to said cutting cylinders.

' 3. In a web assembling apparatus for printing presses and the like, the following elements in combination: a former over which a plurality of webs of paper may pass, means for feeding said webs of paper, a pair of cutting cylinders for said webs, located out of the normal line of travel of said webs, and means intermediate said former and said cutting cylinders adapted to separate said webs and separately direct the same with reference to said cutting cylinders.

4:. The method of deflecting a group of webs of paper out of a straight line and into a new direction at a substantial angle to their then path, without wrinkling or buckling, which consist-s in dissociating said webs, leading same separately toward a pair of cutting cylinders, associating said webs and subjectilng same to the action of said cutting cylin- BPS.

In witness whereof I have hereunto signed my name this 25th day of May. 1926.

LOUIS A. SCHMIDT.
