Application filed August 3, 1925. Serial No. 47,731.

This invention relates to certain improvements in web feeding mechamsms.

In certain types of web feeding mechanisms, particularly mechanisms for vforwarding and directing webs such as are used in web printing machines, it is fre uently desirable tochange the run of the we from one direction to a direction at an angle thereto, usually a right angle. This is done 0 by means of rolls or bars commonly known as turner bars, these-bars being set at the desired angle to effect the change in direction required, the web being drawn against these bars and turning thereover.

With this class of mechanism it frequently happens that if the bars over whichthe we is 'ledare not dry or-if a fresh printed portion of the web comes incontact with the bar, smut-ting of the web occurs, thereby producing imperfect products. Another feature of this type of mechanism is that an unnecessary amount of friction develops between the web and the roll, so .that the web does not run through the mechanism with the desired facility.

It is an object of the present invention to provide a construction by the use of which the web is so supported between its mar or other unprintedportions that the printso ed portions of the web do not come in contact with the surface of the bar as the web turns around the bar.

A further object of the invention is 'to provide a construction by which this may be accomplished in a simple and inexpensive manner and in which the friction between the web'and the roll or bar is substantially reduced.

With these and other objects not specifically referred to in view, the invention consists in certain novel parts, arrangements and combinations which will be described with reference to the accompanying drawings and the novel features pointed out L5 in the claims hereunto annexed.

' In the drawings+ Figure 1 is a plan view of so much of a web feeding mechanism as is necessary for an understandin of the invention, the view 0 being partly 'brdlren away;

Figure 2 is a side view looking in. the direction of arrow 2 of Fi 1;

Figure3 is a detail a? one end of an improved roll; and V Figure 4 is a sectional view of one'of the tion in the brackets in of the web from coming in contact with the direction changing devices by which the web direction is changed, the printed portion of the web being kept out of contact with the surface of such devices.

accomplished in various ways, inthe particular construction illustrated, this is effected by providing a. thin layer of air or the like around the turner on which the unprinted portion of the web, in'eifect, floats and is kept away from the turner surface.

-While the particular mechanism b which ance with the invention, means are provided for preventing the printed surface rolls, taken on the line in the direction of While this may be this may be effected may vary widely -in character, in the particular construction shown of the web are in the form of rolls or bars ber of purposesv required in any particular press.

the devices for changing the direction These bars or rolls are or may be identical in construction and a description of one will suiiice for all.

As shown, this bar is a hollow bar and is provided with a series of apertures which are shown in the form of Ion slots 2. This construction eifects a good distribution of air over the roll surface, butit is understood that other forms of apertures, such as perforations, can be used within the invention.

tion shown, arranged at an angle of 45? These bars are, in the particular construc- 7 to the run of the web and are provided at.

each end with solid heads 3, 4, which are supported in brackets '5, 6,and held in posiany suitable manner, as by bolts 7. In the best constructions, these bars are adjustable so that the angle of the bar may be varied as desired. In the particular construction illustrated the brackets 5, 6 are secured to short shafts 8, 9, these shafts being slidingl brackets .10, 11. One of t ese shafts, as shaft 9, has threaded thereto a handwheel 12 mounted in.

held in position in any suitablemanner, as

by a washer 13.

In the best constructions means are provided for adjusting the bar in the brackets 5, 6 and to eifect this-there is provided at each end of the roll or bar adjusting screws passing throu h ,a slotted extension 14 of the brackets 6,before referred to. The bolts 7 are tapped into the heads I 3, 4 from the under side, passing through a hole in the brackets 5, .6 larger than the screws, as shown at the right hand side of Fig. 2. By loosening the bolts 7, therefore, and turning the screws 15, the bars 1 may be given a slight adjusting movement to vary the angle of the bar and thus compensate for irregularities in the web. By adjustingthe hand-wheel 12, the whole bar, brackets and heads ma be iven a back and forth movement to ad ust t e web with respect to the margin bearers 22;

Air, or other suitable fluid to form the supporting layer ofthe web, is supplied to the roll under pressure, in any..-'suitable manner. In the particular construction illustrated, one of the heads, as the head 3 of the bar, has a hole or passageway 16 formed therein, this hole connecting to the inside of the bar. This aperture is connected at its outer end with a flexible fitting 17, which, through elbow coupling 18, is connected to an air supply pipe'19, to which air is supplied under pressure from any suitable source, not shown. The web marked W is forwarded togthe turner bars over the roll 20 andunder the usual propeller roll If desired, the margins or unprinted portions of the web ,may be supported on bearers, these bearers. being shown in the form of strips 22 shown as rovided at the two side margins of a web. t will be understood that while these bearers are desirable under certain circumstances, they may be omitted if desired.

It will be seen that, with the construction shown and described, a very effective antismut device has been provided in that the printed surface of the web does not come in contact with the surface of the turner rolls or bars. Furthermore, friction "has been largely eliminated and an easy run of the web is effected.

While the invention has been shown and described in its preferred form, it will be ,understood that various changes and varia tions may be made in the articular form of turner devices used an the particular means for mounting these devices in the machine, without departingfrom the invention as defined in the appended claims.-

What is claimed is:

1. In a webfeeding mechanism, the combination of a hollow roll or bar over which a web is led, perforations in the bar widthwise thereof and means for supplying air under pressure through the perforations, margin bearers on the bar, brackets in which the bar is mounted, mechanism for moving the brackets for adjustin the bearers relatively to the web, and ad usting mechanism for adjusting the angle of the bar relatively to the web.

2.- In a web feeding mechanism, the combination of a hollow roll or bar over which a web is led, apertures in the bar and means for supplying air under pressure through the apertures, margin bearers on the bar, brackets for the bar, adjusting mechanism to which the brackets are secured for moving the bar for bearer adjustment, bolts extending throu h a clearance in the brackets for securing t e bar thereto and anadjusting screw for effecting an angular movement of the bar relatively tolthe bracket.

In testimony whereof, I- have hereunto set my hand.
