This invention relates to the feeding of; the web in a printing press from the press to the folder. It is customary to dampen the edges of the web before they go through the press so that these edges will be slightly expanded by the water and flattened out between the several pairs of rows through which they pass. In cases in which the web is slit after itis passed through the press this leaves slit webs with one edge dampened situation as it is likely to skew the web as it passes over the turning bars and even through pairs of guiding rolls.
The principal object of this invention is to provide for overcoming this difficulty so that both edges of each slit web after it is slit will be dampened.
Reference is to be had to the accompanying drawings in which 3 Fig. 1 is a side view of a printing press, diagrammatic in form, showing the application of this invention thereto;
Fig. 2 is a diagrammatic plan with thev web broken away to show the means for dampening it;
Fig. 3 is a side view showing the application of another dampening means;
Fig. 4: is a plan similar to Fig. l'of the modification shown in Fig. 3;
Fig. 5 is a side view of another modification; and
Fig. 6 is a plan of the same.
For the purpose of securing a dampened region along the web at the center or at any. other point at which it is to be slit, I simply provide a water fountain 10 extending all the way across the press near the web roll 11 and place a shaft 12 across the fountain; In addition to having two rolls 18 for the fountain applying moisture to the edges of the web along the regions 14; thereof, I employ also a central roll 15 for applying moisture along the region 16 at the center of the web or other position in which the web is to be slit. This roller is practically twice the width of the rollers 13. v
The web then travels from and 15 through the printing couple and to the rollers 1 3 the slitter 18. This slitter cuts the web along.

the center ofthe dampened'areal6, separating it into twowebs as will appear. Now both of these. webs; are dampened, at both edges so that the two edges will pass over turner bars 20 and act alike. There is no tendency to draw either web toone side on account of anydifi'ere'nce in the-edges. One web is taken through the turnerbars20 in the usualway and brought under the other web to the folder 21. V y r In theform shown in Figs?) and 4c, the conditions are substantially the same except that the moistening is done by two steam jets 23 at the sides and a steam jet 24 at the center which provides similar conditions on-the. web
In the form shown in Figs. 5 and 6, the rollers 13, although not shown in these figures,
are used in a similar manner to that shown in-Figs. 1 and 2 but it will be understood that these rollers 13 are mounted in the usual way and without any central roller. In this case an'extra fountain 25 is employed located beyond the slitter 18. There is no need of any moistening before the slitting takes place and furthermore the moistening of the paper adds dilficulty in some cases to theslitting of the web along the moistened portion. In this fountain is a roll 26 which applies a strip of-moisture to the'web in line with the slitter so that. immediately after slitting the two webs are moistened on both edges.
. With any of these constructions the slit 'webs, as they pass from the slitters, no matterhow many in'n'nmber they may be, are
moistened along both edges. The two edges of each portion ofthe. webnwill act alike throughout the rest ofthe manipulation of the webs.
Although 'I have illustrated and described.
only three forms of the invention I am aware of the fact that other modifications can be made therein by any person skilled in the art and that the invention can'be applied in other ways without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited toany one of these forms herein disclosed,but what I do claim is 1.
