over of the pages thereof, and in some in-- stances facilitating the folding of the web. The invention more particularly consists in means for imparting reverse creases in the web at the line of fold or upon either side or both sides of the line of fold for accomplishing the above .objects A. practical embodiment of the invention is represented in the accompanying drawings in which so much of a web folding machine of that type which provides a back margin fold lengthwise of the travel of the web, as is necessary vention, is shown.

Figure 1 illustrates the machine in front elevation'. Fig. 2 is a view of the machine in side elevation. Fig. 3 is a detail section.. showing 4the geared connection between the first creasing disk and its roll and the geared connection between the second creasing disk and its roll. Fig. 4 is a detail section taken through the web creasing means. Fig. 5 is a detail section taken in the plane of the line A--A of Fig. 3. Fig. 6 is a detail section taken in the plane of the line B-B of Fig. 4. Fig. 7 shows ways in which the web may be creased. Fig. 8 shows a group of three creasing disks for creasing the web at the line of fold and y upon opposite sides of the line of fold. Fig.

9 shows two creasing disks arranged to crease the web *upon opposite sides of the shows two creasing disks arranged for creasing the web at the line of fold and upon one side thereof, and Fig. 11 shows two creasing disks arranged to crease the web along the line of fold and on the other side thereof.

The two superimposed webs a are herein shown as beingv divided longitudinally into two superimposed narrow webs by the roto fully illustrate my ina few of the many Specification of Letters Patent. 'Fatemi-,Qd Jun@ 13, 1916. Application led September 23,y 1913. I Serial No. F(91,333. i

tary slitter 1, which coacts with the roll 2 over which the webs are passed.

The two narrow `superimposed webs are passedl over their respective V-shaped formers 3 and between the customary fold setting rolls 4, 5, for imparting a back mar# gin fold lengthwise of the travel of the webs. The two sets of narrow superimposed folded webs may then be associated and ledbetween the coacting and folding cylinders 6, 7, and the associated and folded sheets maybe 'again folded through the rolls 8, 9, by the blades 10 on the cylinder 7. A rotary sheet dropper 11 is arranged to receive the product from the rolls 8, 9, and deposit it on to the endless delivery carrier 12.

i. The means for creasing the narrow superimposed webs either( along the line of fold or upon one or both sides of the line of fold, is herein shown as comprising one or more creasing disks 13, which coact with the roll 2, and one or more creasing disks 14 which coact with the roll 15, around which rolls their way to their respective ormers.

Gears 19, 20, 21, 22 connect the roll 2 with the shafts ofthe slitter 1, and creasing disks 13, and gears 23, 24, connect the roll 15 with the shafts of the creasing disks 14. A train of gears 25, 26, 27, 28, 29, 30, 31, 32, 33, connect the slitting and creasing mechanisms with the fold setting rolls 4, 5.

The roll 2 is provided with a circumferential groove 16 for receiving the slitter 1. This roll is also provided with three circumferential grooves 17, which are arranged to receive one, two or three of the creasing disks 13. The roll 15 is provided with three circumferential grooves 18, for receiving one, two or three of -the creasing disks 14. In Figs. 1 to 6 inclusive, one creasing disk 13 is shown clamped in position between the adjustable collars 34, 35, and one creasing disk 14 is shown as clamped between the adjustable collars 36, 37. The two creasing disks are so arranged with respect to each other that the superimposed narrow webs are creased lengthwise of their travel upon opposite sides of their line of fold, the crease the superimposed folded. Y

3. In a web folding machine, means forl ing disk 14 are used, they may be adjusted along their shafts so as to reversely crease webs along their line offold, instead of creasing the same upon both sides ofthe line of fold. Y

In Fig. 8, I have shown three creasing disks arranged to crease the superimposed webs at and upon both sides of the line of fold. In Fig. 9 I have shown two creasing disks arranged in position to crease the superimposed webs upon both sides of the line of fold. In Fig.l 10, I'have shown two creasing disks arranged to crease the superimposed webs at the line of fold and upon one side thereof, and in Fig. 11, I have shown the two creasing disksarranged to crease at the line of fold and along the other side thereof.

While I have shown two superim-` .posed main webs, it is to be understood that one or more webs may be run through the machine as desired. Also, while I have illustrated two V-shaped formers and one slitting mechanism, it is to be understood that any number of formers and slitting mechanisms may be used.

I have vshown in Fig. 7, a number of different methods of creasing the web a, and I have shown in Figs. 8, 9, 10, and 11 a number of different arrangements lof the creasing disks 13 or 14, but itis obvious that these are only a few of the many combinations which might beemployed to `produce the creasing of the What I claim is: l

1. In a web folding machine, means for `folding the web and means for creasingthe web upon:v one side of and in close proximity to the line of fold.

2. In a web lfolding machine, means for folding web upon one side of and 1n close proximity to the line of fold before the web is web or webs as desired.
