15 Claims.

This invention is an improvement in newspaper web printing presses and its object is-to enable a web printed on any one unit of the press, and bearing some special feature, to be assembled or associated with any other web printed on some other unit of the press instead of being confined as heretofore to that relative position in the final assembly of the webs in which it would ordinarily appear.

The web bearing the special featured page is usually arranged-so that such page will appear as the title page, or page 1 of the finished paper, but at times it is desirable to divert at least such special feature page to some otherportion of the finished product, and my invention provides a means to do this.

To facilitate an understanding of the invention it should be understood that newspapers consisting of a large number of pages are usual- 20 ly delivered in sections. Some of these sections contain pages which have special features which differentiate them from the usual newspaper I page. These features may be half tone cuts,

additional colors, or matter printed-by-a-diiferent type of printing from the remainder of the paper. These features may be required-onthe title page, (page 1), or on the first page-0f any section of thepaper, or they may be requiredon an inside. page of any section of the paper.

The modernnewspaper press usually embodies a number of perfecting units each capable of producing from four to eight perfectedpages according to whether-the plate cylinders are twoplate or four-plate long. Usually in a four-plate Wide press each printing unit-or deck has associated with it a group of angle bars to divert one longitudinal section of the web out of the straight line passage to the folder and place such diverted :section'of the web over or under the remaining straight running section, both sections being then led to the folder. If the usual style of four-pagewide newspaper presses is operated atfull capacity, each perfecting unit will print eight pages, four on each longitudinal section of the web, and these may be run to and through the folder and delivered as :separate eight-page papers; or thewebs may be combined with the webs printed byother units and delivered in sections each containing more than eight pages up to the full page capacity of the .press.

With the customary two former folder, two sections only can be delivered on straight run, or four sections whenrunning collect. When the entire product is folded together (pool; fold) there will be no question of sections, but the ability to place special pagesin various positions is equally valuable.

One unit or deck of the-press maybe equipped with mechanism to print special page features as mentioned above. This special unit usually has its product delivered-to the folder to appear on the title page, or pagel of the finished product; but as stated-it is advantageous at times to be ableto divert -at least such special pages to some other position in the finished product. Heretofore this has not been practical, but my invention enables this to be doneby diverting the Web or section oi -the web bearingsuch special feature page to the line of the section of the web with whichitis to be assembled prior toreaching the folder.

F-orthis purposeI provide a leading in roller adjustable in position andrelated roller and angle bars where a web section from anyunit may be associated with a web section from any other unit. To enable others to-understand-and use the invention I will explain the same withreference to the accompanying drawings and summarize in the claims the essentials of the invention and noval features of construction and novel combinations of .partsfor which protection is desired. 1

- The drawings show the angle bar assembly of a six unit (or sixdeck) newspaper printing press 4 pages wide, and as usuallyfurnished there is one set of angle bars (consisting of two bars) for the .product of each unit. Such angle bars are preferably placed between the printing units and the folder.

In "said drawings:-

Fig. 1 is a side elevation of part of a six unit or six deck newspaper printing press and folder, partly broken away, to show the angle bar or sheet assembly section of such press equipped with my invention.

Fig. 2 is a top plan view of the usualangl'e bar, or sheet assembly, section of a six unit or six deck-press equipped with one embodiment of my invention. 45

'Fig. 3 is a side elevation of Fig. 2, the side frames being omitted.

Fig. 4 is a'right hand end elevation of the assembly "shown in Fig. 2.

Fig. 5 is a right hand side elevation of Fig. 4.

Fig. 6 is :a. detail top plan view of the sheet assembly shown in Fig. 1 with a further embodiment of my invention. I

Fig. 7 is a side elevation of the assembly show,-

ingthe adjustable web deflecting rolls.

The printing mechanism may be of any suitable construction, either of the unit type, or the superposed deck type. To simplify explanation of my invention I have shown and will describe it as used in connection with a multi-unit press having six web perfecting units A, which are substantial duplicates, a folder F, and an angle bar or web assembly section B located between the printing units and the folder. Each unit A is adapted to print a web, which webs are led from each unit to the assembly unit and thence to the folder in the usual way. The web assembly mechanism shown is for a press capable of producing a newspaper of 48 pages from six four-page wide webs (W, W2, W3, W4, W5, W6) printed on plate cylinders four pages wide (folder not collecting). Each four-page wide web is led from the related printing unit A of the press to a guide roller 2 adjacent the assembly section, and at oradjacent its related roller 2 each web is slit longitudinally by a slitter 3; and then customarily in ordinary machines one longitudinal section of the Web (as Wb, Fig. 2) is led directly to and over a guide I2 at the opposite side of the assembly mechanism to the usual assembly roller 20, at the top of the folder by which the assembled sections of the web are directed to the folder and thereby folded longitudinally in the usual manner. 7

In Fig. 4 I have shown rolls with slitters 3 only at the upper group of angle bars (for web W) and at the fourth group (for web W4) The slitter mechanisms for the other groups being omitted in order to more clearly show the additional angle bars 9.

In the drawings my invention is shown as applied to a. four-page wide. press, but it would be just as useful applied to a two-page wide press.

Heretofore the other longitudinal section Wa of the web W is led to and over an angle bar 4a by which it is deflected at right angles and then led beneath the web section Wb'to and over a second angle bar 41) (parallel with bar 411) by which it is again deflected at right angles parallel with and below section WI) and directed, together with web Wb, to and over roller I2, and thence to the folder.

A similar set of angle bars (such as 4a, 4b above described) isprovided for each web, as indicated in Fig. 2; said angle bars being supported on transverse rods or bars Ia attached to side frames I, as, indicated in Figs. 2 and 4, and ordinarily each of the webs W, W2, W3, W4, W5 and W6 (Fig. 3) coming from its related printing mechanism is divided and its sections assembled in the same manner as above described web W.

As thus far described the construction is old.

In my invention I provide a roller 6 at one side of the assembly Bin the plane of one of the angle bars 4a. As shown in Figs. 2 and 5 roller 6 is journaled in brackets 6a, which may be fastened to the side frame I in fixed position. The brackets 6a may also form bearings for the upper ends of vertical screw rods 8; the lower ends of which are journaled in brackets 8a (Figs. 4 and 5) which are fixed to the side frame I. Bevel gears 8b may be mounted on the lower ends of the screw rods 8 and mesh with bevel gears mounted on a horizontal shaft 8 journaled in brackets 8d fastened to frame I. The shaft 8 may be provided withmeans for revolving it, a crank 8e being shown for manual operation, but a motor drive may be utilized for more rapid movement.

Parallel with roller 6 is an adjustable roller 1 which is shown as journaled in brackets 1a threaded onto screw rods 8, the bases of the brackets preferably having a sliding engagement with the adjacent frame I and having tongues 'Ic sliding in grooves la in the frame I (Fig. 4).

I also provide a third angle bar 9 for each group of angle bars 4a, 4b below the top group, each bar 9 being arranged at right angles to the bars 4a, 4b (see Fig. 2) and at the side of the frame adjacent roller 6.

By revolving shaft 8f screws 8 can be revolved to raise or lower the brackets Ia and move roller 1 to a position opposite the desired group of angle bars. Roller I may be locked in adjusted position by pins lb entered into holes Ib in the frame members I. The roller 6 may be also adjustable like roller 1 as hereinafter described.

When the webs are led in the usual manner, the web section Wa will be led to the folder under web section Wb. But if desired the side roller 1 can be adjusted to a position opposite one of the lower groups of rollers, for example as shown in Fig. 4, and the web section Wa led from the angle bar 4a to and over roller 6 and down under roller I and then led inward to and over theangle bar 9 of the third group of angle bars and then to the folder between the sections of web W3. By properly adjusting roller 1 web Wa can be assembled with any other web sections than web section Wb, for instance as shown in dotted lines in Fig. 4 the roller 1 is positioned to direct web section Wa into association with the lower web W6.

The rollers I2 to IZk in Fig. 3 are for guiding the separate webs to the folder. For some products, a web is run full width (4 pages wide in a 4-page-wide press) on the way to the drag roll over the folder and slit at or near that roll. For other products each web will be slit as shown'in the drawings, one portion running straight line to the folder and the other portions using angle bars. Still other products run the webs using both the above sets; for this reason I have shown enough rollers in Fig. 3 to provide one guide for each half web as usually used and one extra guide (I3 to I3e) for each printing unit to guide the web from the special printing unit at each of the positions to which it may be led. As there are about 250 different products or arrangements of pages etc., that can be produced on an octuple press provided with two folders and two additional formers (air plane former), there must be provided means to carry every half web printed to the folder.

In the ordinary press each of the webs W to W6 would be split and assembled together in the same manner that the upper web would be assembled. For instance, in Fig. 3 the web Wa is diverted but Wb runs horizontally to the top of roll I2; the roll just under roll I2 is not used when the web Wa is diverted but is in place to use if the web Wa were run over both angle bars, the top of this roll being alined with the angle bar 42). On the next deck below half webs Wd and We are shown as using their guide rolls but there is a roll in position to receive a web from the extra angle bar which is not used until the web Wa. is diverted to use this bar.

As shown in Figs. 2-5 the sections of the upper web can be associated with any section of a lower web or vice versa, but by providing proper 75 'rollsany one of the lower web's W6 to W2 could be associatedwithjanyof the other lower Webs W2 toWli; For instance as shown in Figs. 6 and '7 roller"6 could bemadeadjustable as well as roller 1, and such association could be made; that is, the webs WB'and W3 "could be associated, or W5 andWZ etc. "As shown in-Figspfi and 7 the roller 6 is journaled in bearings 6|], which may be similar to bearings Ia of roller 1, and slidable in ways parallel with the ways of bearings la. The bearings '60 are adjustable by means of screws 6| which are journaled in brack 'ets 62 and '63 attached to the side framel. Bevel gears 64 attached "to upper ends of screws 6| mesh with bevels 65 on a shaft 66, journaled in brackets 6'! on frame 'I, and by rotating shaft 66 the roller 6 can be raised or lowered independently of roller 1. With this arrangement a web or section of any web can be diverted and directed to and assembled with a section of any other web.

As shown the section of the web W might be led over :roll 6 and by properly locating roller 1 assembled Withany of the other web sections. Also by properly adjusting roller 1 a section of any web W to W6 may be directed over roll I up over roll 6 and then over the upper angle bar 9 and assembled with the section of the web W, that is, that the web from one of the lower sections could be led up to the upper section in the same manner that the web is described as led from the upper section to one of the lower sections but in the reverse direction. For practical reasons the paper will run to better advantage from the top roll to the lower position than from the lower position to the top. In order to reverse the direction another angle bar 9 could be added to each upper group of angle bars.

My invention can be installed in one special unit in a press whereas without my invention it would be necessary to install more than one unit to get the same result. My invention therefore eliminates the costs of such additional machinery as well as requiringmuch less space in order to accomplish the desired variation in web assemblies.
