This invention is a novel means for cross associating webs of paper from one row of printing press units to an adjacent parallel row, and from thence to a common folder in which the webs are folded, severed; stacked and delivered therefrom for public use, and the principal object of the invention is to provide a simple, novel and adjacent arrangement whereby the usual multiplicity of angle bars and guide rolls which are customarily used in conventional methods in use at the present time will be eliminated; said means also eliminating the use of balcony leads for bringing the. specific side of a printed web into the proper arrangement over a folder, but instead said means providing a straightforward movement of the running web, whereby the uppermost printed side of the web as it leaves a press unit will be the uppermost side as it passes over the drag roll to the folder.

Before proceeding to the common folder the running webs of paper from the rows of printing units are collated in perfect register at a common point, such as a drag roll, adjacent the folder; and another object of my invention is to provide a novel, simple, and efficient angle bar arrangement which is adjustable so that the running webs of paper collated at the drag roll will be in perfect register.

Other minor objects of the invention will be hereinafter set forth.

I will explain the invention with reference to the accompanying drawings which illustrate one practical embodiment thereof to enable others familiar with the art to adopt and use the same; and will summarize in the claims, the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawings:

Fig. 1 is a plan view showing a typical prior art means for efiecting cross-association of webs from one row of printing units to another parallel row.

Fig. 2 is a diagrammatic section on the line 2-2, Fig. 1.

Fig. 3 is a plan view showing my novel means for cross-association of the webs from the parallel units.

Fig. 4 is a longitudinal section on the line L-t, Fig. 3.

Fig. 5 is a longitudinal section on the line -5, Fig. 3.

Fig. 6 is an enlarged vertical transverse section through one of the adjustable angle bars, on the line 6-6, Fig. 3.

Fig. 7 is a top plan view, partly in section, of the angle bar shown in Fig. 6.

As shown in the prior art views, Figs. 1 and 2, the usual means for cross-association of webs between parallel printing units A and B is as follows, assuming that the Web W from pres A is to be cross-associated with the web V from the press B and delivered over common drag roll G into common folder Y. As shown the printed web W from press A passes in the direction of the arrow to! in its passage out of press A and runs over a series of guide rollers D to a roll E and continues in the direction of the arrow 202 to an angle bar F of press A, the web then passing in the direction of arrow w3 to a balcony or side issue roll G and then continues in the direction of arrow 204 and over a series of guide rolls H to an angle bar J on the delivery end of press B, from whence the web is turned in the direction of arrow w5 and passes with web V off press B coaxially of said press B in the direction of arrow wt to drag roll C, and from thence to folder Y, the webs W and V from presses A and B being in register at the drag roll 0'.

In this prior art construction the angle bars F and J are set at angles of and this arrangement requires the series of guide rolls H mounted in supporting framework between the presses A and B, and also requires the fbalcony or side issue rolls G of press A in addition to its supporting brackets and framework in order to convey the web W and deliver it in its proper relationship or register with respect to web V from press B, to drag roll C, and with the uppermost printed side of web W presented as the uppermost side thereof as it passes over drag roll C. While Figs. 1 and 2 show a conventional prior art arrangement of Web crossassociation, it is understood that more than one web can be manipulated in a similar manner to that shown therein to convey the printed webs of paper from any number of roWs of printing units which may be practical and within reason to the common folder Y; and said units may or may not be provided with superimposed color decks.

My invention provides a much simplified arrangement or .means shown in Figs. 3, l and 5 which dispenses with the balcony or side issue roll G (Fig. 1), and the series of guide rollers E (Fig. 1), and which will deliver the web W in its proper relationship or register with web V from press B to the common drag roll 0 with the uppermost printed side as it leaves press A presented as the uppermost side as it passes over drag roll C.

As shown in Figs. 3, 4 and 5, the Web W, just prior to leaving press A, proceeds in the direction of arrow w'I to and over a guide roll I upwardly and over a drag roll 2, from whence it passes in the direction of arrow 108 over and under an adjustable angle bar 3, the web then passing in a diagonal direction, indicated by the arrow 209 under and over a stationary bar 4 extending between the presses A and B, the web continuing in the direction of arrow will to an adjustable angle bar 5 on press B, the web passing over and under angle bar 5 as indicated by the arrow wi2 and continuing in the direction of arrow wI3 to the common drag roll 0, the web being thus associated with the web V from press B before passing into the folder Y. In my arrangement, the uppermost side of web W leaving press A is presented as the uppermost side of the web at drag roll C as clearly shown by the full and dotted arrows in Fig. 3; and it will be observed that by my arrangement no balcony or side issue rolls such as G (Figs. 1 and 2) are required or necessary, nor their attendant brackets which support such roll; nor are any guide rolls H necessary between the rows of presses as required in the prior art arrangement shown in Figs. 1 and 2.

When a web of paper leaves one row of presses and is collated with a series of webs in an adjacent row of presses, it becomes necessary to bring this .one web into proper alignment with the other webs before proceeding to the folder. Furthermore, the web to be cross-associated must be .delivered to the adjacent row of presses in such a manner that it will move in the proper path in harmony with the webs it is to be folded with. This necessitates a double adjustment of the angle bars 3 and 5, one adjustment being for angular control to cause the web to travel in a parallel path along the central axis of the second press, while the other adjustment is to bring the web into axial alignment with the webs with which it must be collated. This double adjustment is accomplished in a novel and simple manner as follows, but as the said double adjustment means is the same as applied to both angle bars 3 and 5, only one adjustment, i. e., of the angle bar 3, is described herein, the same being indicated in Figs. 6 and 7; it being understood that the adjustment of angle bar 5 would be identical with that shown in Figs. 6 and. 7.

As shown in Figs. 6 and '7, angle bar 3 (or 5) is supported by two brackets 6 and I which are pivoted on shaft sections 8 and 9 by means of swiveled studs l and II respectively. The shaft sections 8 and 9 are respectively journaled for sliding movement in the side frames I2 and I3 ,of the press A (or B) and are constrained to move at right angles to the press framing i2-I3, the shaft section 8 being slidably mounted in a guide sleeve I4 in a bore in frame I2, and a bore being provided for the shaft section a in the press frame I3. Guide sleeve M is held in fixed position in the bore in frame I2 by means of screws I9. Adjustment of bar 3 at right angles to the press framing is effected by means of a rotary adjusting screw I which is in threaded engagement with a tapped bore I5 in the end of the shaft 8, screw I 5 carrying a handwheel H on its outer end pinned thereto by a pin I8. Screw I5 is confined against axial movement in the outer end of sleeve I4 by any suitable means. By this arrangement any rotary movement of handwheel I! will cause a sliding motion to shaft 8, within guide sleeve I4, and by reason of the confined length of the angle bar 3 a similar sliding or parallel motion is imparted to the shaft 9. Consequently any movement of handwheel I'I will cause the web to change its relative position in parallelism to the side frame I2, for example, and at the same time change its parallel location with respect to the framework of the adjacent parallel press such as B.

Adjacent bracket 6 on angle bar 3 is a fixed collar 28 rigidly attached thereto by a set screw 2i. Rotatably journaled in collar 29 is an adjusting screw 22 having a threaded end 23 in engagement with a corresponding tapped hole in bracket 6, said screw 22 being constrained against axial movement in collar 20 by any desired means. A set screw 24 is provided in collar 20 to definitely maintain the adjustment of screw 22 after it has once been made. At the other end of the angle bar no relative motion of the bar and the bracket 7 can take place, because these pieces are rigidly held together by screw 25.

By the above arrangement, any adjustment of screw 22 will force the bar 3 away from or towards the bracket 6, and because both brackets 6 and l are pivoted around studs I0 and II, and because bar 3 is constrained at one end by clamping screw 25, it follows that shaft section 9 must move inwardly or outwardly in respect to side frame I3 as screw 22 is adjusted. A geometrical consideration shows that any changing of the length of the hypotenuse of the triangle conceived by a line joining the centers of studs I9 and II, without change in the length of one leg of the triangle as indicated by the line P (Fig. '2) will produce an alteration of the included angle Q. Thus the web W is caused to travel in its proper state of parallelism with respect to any of the side frames I2 or I3 of the press unit.

Comparison of the two arrangements shown in Figs. 1-2, and in Figs. 3-5 respectively, will show the simplicity, economy and efficiency of my means for cross-association of webs. There could be any number of press units in each row of presses A and B, all of which may or may not have superimposed color decks, as the particular customers requirements specify. The adjusting method for angle bars 3 and 5 are secondary to the main object of the angle bar arrangement which is to provide an arrangement embodying simplicity and fewer number of parts in its construction. Figs. 6 and 7 show but one embodiment of the bar adjusting means, the same being a preferred arrangement; and hence I do not limit my invention to the exact form shown in the drawings, for obviously changes may be made therein within the scope of the claims.
