This invention relates to a newspaper printing machine folder' for use principally in folding tabloids-.1`

. Theprincipal objects of the invention are 53 to 'provide' an arrangement of the folding unit such that when folding tabloids the slit product can be run successfully into the folding unitf'riom either sideand the margins of the two halves of the web will register dilol reetly, and to eliminate the compensation rollers' usually employed.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the'accompanyf; ing drawings in which Fig. 1 shows a folder arranged in accordance with this invention for receiving the websfrom one side; and

Fig. 2 is a similariviewshowing the posiid' tion' for receiving themfrom'theother side.

When running a newspaper product in a transverse collect run, that is, from both former-s into a single folder unit it has been found very difficult, ifr not impossible, to run the product over compensating rollerswhen the product is'slit over the former rolls as is the casein a tabloid newspaper.

In the ordinary practice the websare run from` the right handI former into the left hand folder, and vice versa, over compensating rollers. This works well enough for ordinary newspapers where the edge is folded.

It cannot be done with a tabloid slit edge paper without causing too much puckering i or gathering of some of the webs over the others.

I obviate this difliculty by eliminating the adjustable compensating rollers and employing a pair of nipping rolls on each folder j unit over the folding rolls and movably independently of the formers. The split web is shiftable from one side tothe other without moving the nipping rolls. It will be understood that a pair of nipping rolls, usually employed with each former, are retained in the same position as usual.

In the drawings, I have shown a. construction comprising a pair of folding units 10. Each folding unit embodies the usual foldg "1 ing mechanism including a pair of folding its.

cylinder 11 and 12 mounted on the frame of the unit 10, and also a pair of nipping rolls 13 also supported by' this frame directly over the folding couple.` This is used in conjunction with the two formers 14 and the former rolls 15 and the nipping rolls 16 placed directly below the noseof the former and mounted in a stationary positionl on the frame of the machine.

In the position shown in Fig. 1, thetwo webs from the two formers are run directly from the nipping rolls 16 tothe nipping rolls 13 of one of the folding units which nip them at their marginsand direc-t them in a short straight path into the folding couple. ,In this way the two webs are collectedy at the left ide as shown in Fig. 1. l

lVhen it is desired to collect them on the right side the other folding unit 10 is used as shown in F ig. 2, and it will be seen that the relationship between the nipping rolls 13 and the folding couple is the same as in the position shown in Fig. 1. However, the run of the webs is different. folders are so located that the margins 17 of the webs coming from bothformers will meet and register with thefolder without the necessity of running either of them over compensating rollers. As the margins on one half the webs are staggered with respect to those on the other half, it is necessary to place the folder in each of the positions shown out of line. y between the nips of the rolls 13 directly over the folder unit they will register directly,`

as is indicated.

In this way tabloidipapers with their slit edges `can be run through to either of the two folders without material puckeringl or gathering of some of the webs folded outside the others. Also the compensating rollers with their supporting parts are eliminated altogether and the nipping r'olls which are a,

part of the folding mechanism are mounted in stationary bearings, o: such bearings as may be desired to adjust them, without pro- O'n each side the Thus when associated viding for the long adjustments necessary in many cases for the usual compensating rollers. Y y y Although I have illustrated and described Cri only a single form of the invention I am aware of the fact lthat 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 to the exact form shown, but what I do claim is 1. In a newspaper folding machine, the combination with a pair of formers and their nipping rolls for receiving and directing two webs, of a folding unit located at one side of the center, a frame for said unit and a pair of nipping rolls carried by said frame independently of the formers and directly over the folding unit for receiving the webs from both of the pairs of nipping rolls on the formers. l

2. In a folding machine for a newspaper printing press, the combination with a pair of formers for receiving the two halves of a slit web, and nipping rolls associated with the formers and in line with the noses thereof, of a folding unit having a folding couple, a frame for said unit and a pair of nipping rolls carried by said frame directly over the folding couple and receiving the two webs directly from the nipping rolls of the two formers.

3. In a folding machine for a newspaper' printing press, the combination with a pair of forxners for receiving the two halves of a slit web, and nipping rolls associated with the formers and in line with the noses thereof, of a folding unit having a folding couple, a frame for said unit and a pair of nipping rolls carried by said frame directly over the same and receiving the two webs directly from the nipping rolls of the two formcrs,

vthe second pair of nipping rolls being located out of line with the first pair, for the purpose described.

4. In a folding machine of the character described, the combination with a pair of -formers for receiving the two halves of a slit web and two pairs of nipping rolls, one pair directly in line with the nose of each former, of a folding unit having` a pair of nipping rolls associated therewith to deliver always directly between the cylinders of the folding couple and located directly over the folding couple in such position that the margins of the two webs coming from the two formers will meet and register on a transverse collect run.

5. In folding machine for tabloid newspapers, the combination of two formers and two folders, said formers each having a pair of nipping rolls carried thereby and located directly in line with the nose of its respective former, a frame for said folders, said folders each having a pair of nipping rolls associated therewith and carried by said frame and located directly above the folder for receiving the slit webs directly, so that each folder will receive the halves of the slit web with their margins in registration.

6. In a folding machine for tabloid newspapers, the combination of two former-s, two folders for receiving the slit webs directly, said folders and formers being so located relatively to each other that each folder will receive the two halves of the slit web and means adjacent to the folders for causing the webs to be led into the folder with their margins in registration.

7. In a folding machine the combination of a. plurality of formers, a movable transverse folding mechanism so arranged relatively to the formers that the folding mechanism may be adjusted with respect to the formers and nipping rolls carried by the folding mechanism so that the margins of the products of the formers shall register when entering the transverse folding mechanlsm.

8. In a folding machine, the combination of two formers, each for receiving one half of a newspaper web, a transverse folder, said folder being movable laterally across the machine and means for directing both half webs into said folder.

9. In a folding machine for folding tabloid newspapers, the combination of two parallel formers for receiving the two slit halves of the web, a folder movable laterally across the machine, and means for directing the half webs from the two former-s into the folder in two positions thereof.

10. In a folding machine, the combination with two formers in fixed position for receiving the two halves of a split web, and a transverse folder movable to a position out of registration with either former in which the margins of the two webs will register with each other as they pass into the folder.

In testimony whereof I have hereunto affixed my signature.

OSCAR CHARLES ROESEN.
