This invention relates to the former of a printing press.

The principal objects of the invention are to provide an extra former or formers in such relation to the usual duplicate formers as to avoid duplication of the drag roller, slitter, and propeller mechanism, thus reducing the expense very materially; to provide an arrangement in which the over head space will be reduced, so that an additional former or formers can be used in rooms not sufiiciently high to receive the usual constructions; to provide an arrangement by which the leading of the web around several rollers between the upper and lower former carriages will be avoided, thus eliminating the creasing of the web by that means; to provide means for avoiding the usual creeping of the tabloid Webs one over another in the old constructions; to provide means for eliminating a slot through which the webs must be led; to provide means for leading the web in just as'easy a manner as though there were no extra formers, to avoid the so-called bay-window which the web has to make around the side of the ordinary duplicate formers when an extra former has been used heretofore; to provide for employing this inven tion with tabloid sheets, and to provide for lead ing the webs in the manner above described from presses out of line with the original line of presses.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a side view showing a plurality of webs coming from a press or series of presses into the folder and showing the preferred em bodiment of this invention;

Fig. 2 is a plan of the series of formers, and showing the direction of the webs thereto;

In the association of products from a printing press in high speed production it is often desirable to produce products of more than one section. In order to produce two sections, the folder may be run collect or the product may be run over two formers and brought into a single folder running straight. This latter is called a transverse run.

It is often desirable, however, to print a prod not of three or four sections. When this is to be done it is customary to place an extra single or double former above the regular ones and to run a number of Webs to them. After these webs were given their full-page folds the paper would be run around several rolls at the sides of the usual double formers, making what is called a bay-window run to a point below the ordinary double formers. There they would be collected, together with the products coming through the usual formers, and delivered into the folder. This would make a newspaper having t ree, four or six sections, depending upon the number of extra formers used, and Whether straight or collect papers were being run.

This arrangement has been open to a number of objections. In the first place, the placing of one or two formers above the usual ones requires a considerable amount of head-room. For that reason this arrangement could not be used in many press rooms. A complete duplication of the drag roller, slitter, and propeller mechanisms was necessary in the old constructions for the upper former group. This practically doubles the expense of this part of the press.

In order to provide these extra webs in the way that is mentioned, space had to be provided between the two former groups, so that there would be room for running the webs from in front of the folder to the rear of the folder in either one of the former groups. The wasting of this space makes the leading of the webs quite difficult. The folded webs having to go around several rol1- ers between the upper former carriage and the lower become badly creased in their passage. In the running of a tabloid it has been almost impossible to prevent some of the sheets from creeping over the others.

By this invention the extra former or formers are placed in line with, and on the same level as, the customary double former with provisions for leading the web, of course, to these extra or auxiliary formers. In this way as many webs as desired are led over turning bars placed out of line with the regular formers. These Webs are then led over either or both of the extra formers, and after being folded page size are transverse collected and led into any of the folding and cutting mechanisms provided. The extra press unit is placed in front of the former from which the web is passed over a slitter roll, half of the web on each side going over angle bars to the auxiliary formers. In this case the webs can all be brought over a single drag roll, and although that is made extra long, there is only one mechanism for operating it.

In Fig. 1 are shown diagrammatically the course of several webs coming from what may be considered the usual press or line of presses 9 over and under guide rolls 10 to the drag roll 11 and from that to the double former 12. The double former, as usual, consists of two formers adjacent to each other for receiving the slit webs from the drag roll and delivering them to the folder rolls 13 and in this case to two sets of nipping rolls l4 and 15 which fold and crease the webs longitudinally. The nipping rolls 15, as usual, deliver the folded webs to the folding couple 16 of the folding machine shown diagrammatically. As so far described this is the ordinary procedure.

When additional webs are to be introduced they can come from a press 17 in this case shown as located on the opposite side of the folder from the press 9 but in line with it, where they pass over guide rolls 18 and turning bars 19 to divert them beyond the sides of the first named webs and bring them over guide rolls 20 to the same side of the drag roll as that on which the guide rolls 10 are located so that all the webs pass over the drag roll in the same direction. These webs, however, from the press 1'? pass beyond the sides of the webs from the other press and all in the same plane. lf'hus only one drag roll is required and only one mechanism for operating it.

For providing tabloid sheets slitters 21 are placed over each former or over any of them. Slitters are also shown in connection with each press.

In this case extra formers 22 are employed. Of course, it will be understood that only one of these would be used if a smaller paper is to be produced. From the single or the two formers 22 the web or webs pass through the folding rolls and the nipping rolls 24 associated with these formers and then to the pair of nipping rolls 15 previously described and then into the folders as usual.

In this case two courses of the webs are illustrated. One set of dotted lines in Fig. 3 illustrates the path of the webs when the three right hand formers are feeding their webs into the left hand folder on one side and the other set of dot and dash lines shows the three left-hand formers feeding into the right-hand folder. The full lines represent the two right-hand formers feeding into the right-hand folder and the two left-hand formers feeding into the left-hand folder. This provides a very desirable means whereby any one of three formers may feed webs into either of the folders.

In Fig. i the extra press 26 is shown out of line with the presses 9 and perpendicular to them. In Fig. 5 arrangement is similar, the extra press not shown) being out of line, but parallel with the original presses 9.

Economy in this construction over the previous ones is obvious since there is only a single drag roller, although it is longer, and only a single means for operating it is used. The need of addiional space for the folders located above is eliminated. A little additional width is required but only a little as a printing press of the modern type is considerably wider than the web used therein.

It will be seen that when running straight papers, they may be delivered in two, thr e or four sections and when running collect in four, six or eight sections depending, of course, on how many formers are in use.

Although I have illustrated and described only three embodiments of the invention I have indicated that instead of four formers, three can be used, the extra one being located on either side of the usual formers, and I am also aware of the fact that other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in this respect but what I do claim is:-

1. In a printing machine, the combination with a-drag roll and a double former, of an extra former located at one side of the double former and in horizontal alignment therewith and in position to receive the web from another press over the same drag roll.

2. In a printing machine, the combination with a drag roll, a double former and a pair of folders located in position to receive the products directly from the two parts of the double former, of an extra former located at the side of the double former and having means for delivering its prodnot to either one of said folders and in position to receive the web over the same drag roll.

3. In a printing machine, the combination with a drag roll, a double former for receiving the slit web from a printing press, and a pair of folders each located in position to receive the products from one f the parts of the former, of an extra former located at the side of the first named formers and in alignment therewith, a second press means for directing a web from the second press over said drag roll to the extra former in the same direction as the webs delivered to the double former and means for guiding the products from the extra former to either folder.

In a printing machine, the combination with a drag roll, and a double former positioned to receive a slit web over said drag roll, of an extra former located in position to receive the web from another press over said drag roll.

5. In a printing machine, the combination with a double former, and a drag roll in position to deliver a slit web from a printing press over said drag roll to the double former, of a second printpress, leans for delivering a slit web from the second printing press in two lines at the sides the path of the first named webs to a point at the back of said drag roll and a pair of formers located at opposite sides of the double former and in alignment therewith in position to receive the slit webs from the second printing press over the same drag roll at points beyond the outer edges of the double former.

6. In a printing machine, the combination with two presses located in line, of a single drag roll, a double former positioned to receive a slit web from one press located in line with said formers, and an extra former located in position to receive the web from the other press.

7. In a printing machine, the combination with two presses located out of line and perpendicular to each other, of a single drag roll, a double former positioned to receive a slit web from one press located in line with said formers, and an extra former located in position to receive the web from the other press.

8. A plurality of presses and a pair of formers arranged in line therewith, in combination with an extra former, located out of line with these presses and formers, and means for conveying the web from certain of these presses over the extra former and for associating the folded webs from all formers into a single folding mechanism.

9. In a printing machine, the combination with a drag roll, and a double former positioned to receive a slit web from said drag roll, a pair of folders located in position to receive the products directly from the two parts of the double former,

of two extra formers located one at each side of said double former and each having means for delivering its product to the adjacent one of said folders.
