CORPORATION or MIOHrGAN' TUBULAR-PLATE `PRESS ANDYFOLDER 'Application friedy July a v192e. senti No. assiali.

This invention is an improvement in web`V printing and folding presses and has'particular reference to single-page tubular-plate ent No. 867,230, dated october 1st,'1907, in

which each plate cylinder carries two tubular single-page plates and prints upon a two -page wide web.

These so-called tubular pressesv operate on the so-called straight line principle, and print duplicate consecutive impressions upon y the web so that no collecting is ever required.

Y The present invention is especially designed for'use in connection with tubular presses having three or more decks and capable of printing E24 or lmore newspaper pages at each operation.' Heretofore. such presses have sometimes been provided with two folders so o that they could print and deliver twopapers over to and associated with the webspassing. the former of the other folder, anddelivered simultaneously in book fold; alsofheretofore` two folders have been arranged one above the` other. to enable two book fold papers to 4be delivered simultaneously from one suchl press.

With such a superposedarrangement of foldf. ers one group.` of webs after passing the former of one folder .could be led to thefirst' fold rolls'of/the other folder so that a single paper wouldbe delivered in ltwo seetions by the latter folder. .Y l V p .Alsoheretofore two such tubular presses have been arrangedside byr side each withaA folder, so that each might deliver la .paper in book fold; or the webs from one -P'ress after` passing vthe former of its folder could be -led as one large paper in two sections'. 4Theuse of a plurality of folders involvesconsiderable expense; Y and v to arrange two folders or' formers oneabove the other necessitates a great deal of head room in the press room, and also requires the pressman -to climb up on a platform to get access to the upper folder or former in threading webs thereto.

The two-page wide tubularv presses heretof fore made with one folder could not deliver` any product in sections; while an, ordinary semi-circular plate `press equipped; 'with du-i plicate plates and lone folder candelivera newspaper. book fold upl to, ful'. capacity,

where such presses are to be installed there isv not sufficient head roomto permit the' use ofan eXtra former or an eXtrajfolder superposed above the other; and to provide duplicate folders dadds materially tothe cost of the outt.`g .p i' 'Ifh'e obj ect of the present invention' is to enable a single width tubular page press, using single plateonly, to deliver itsnproduct either in book fold or in sections, without requiring any additional head room inthe press room, and without necessitating the employment of two folders.

In accordance with my invention I provide meansV whereby Vpart of thewebs coming from the press may be deflected laterally tojand over aformer placed at one side of the press *folder` insu-ch positionI that the webs after passing such former maybe led back to the folder and be assembled with'the webs passing the former of such folder; thus enabling papers to beideliveredV in'-`se`c`tions? ify de-. siredor all'the'webs can be led direct to the folder and the papers be delivered in booky over-the auxiliary former papers can be delivered in sections.

I'have described the delivery of 24 page papers in two equal 12 page sections; but obviously if additional perfecting mechanism or additional decks are employed, papers of larger size and of greater variety can be produced.

With this' invention a single page tubular press of anysiz'e can be made to deliver papers up to the full capacity of the press in either book fold or sections. Of course the size of the papers as a whole, and the number of pages in each section, can be varied according to the number of webs employed.

A press equipped with my invention can be conveniently and readily threadedV by a ed webs from the auxiliary former can be directed to the rst fold rolls of the folder to be assembled with the other webs passing direct to the folder to produce papers in sections.

The auxiliary former F and the angle bars 2a, 3a and 4 can be arranged in line with the space at the side of the press which is required for proper access to the mechanisms of the press, and in order to plate and unpla-te the cylinders.
