O. C. ROE SEN PNEUMATIC WEB SEVVERING DEVICE Original Filed No v; 5, 1927 2 Sheets-Sheet Mezzr .Faesen Patented Sept. 20, 1932 UNITED STATES PATENT OFFICE OSCAR CHARLES ROESEN, OF BROOKLYN, NEW YORK, ASSIGNOR TO WOOD NEWSPAPER MACHINERY CORPORATION,
OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA PNEUMATIC WEB SEVERIN G DEVICE Application filed November 15, 1927, Serial No. 283,442. Renewed December 10, 1931.
The principal object of this invention :is to provide means for severing the web passing to a newspaper printing machine in such a manner that the Web will become separated along a straight line across the web.
Other objects of the invention are to provide means for severing or breaking the web that will not impede the action of the reel, that will avoid the formation of an irregular tail on the severed web which may whip around the rolls, and that can be accomplished by the use of compressed air.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which Fig. 1 is an end view of a web roll reel and cooperating means for feeding the web to the press showing a preferred form of this invention;
Fig. 2 is an elevation of the same, and
Fig. 3 is a horizontal sectional view showing the web severing device in plan.
When making a flying paster it is neces- Sary to sever the expiring web after the incoming web has been secured to it. This has been accomplished in one form or another by the use of a knife that is swung into position at the time.
On account of the nature of the construction of flying pasters it has not been possible to attach the knife in such a manner that the entire web can be cut at .one time. This makes it necessary to cut the web at the edge and rely on the tension to complete the breaking of the web thereafter.
One of the disadvantages of this arrangement lies in the uncertainty that the cut or break will extend straight across the web, as the paper may have various degrees of strength across it. Therefore the web tears in a very crooked line and frequently produces long tails which whip around the several rolls and cause trouble. This invention has for its object to overcome this difliculty.
I have shown the invention as used in connection with an ordinary reel for supporting the web rolls 11 for supplying the web W to a printing press over a guide roll 12. The paster is made'by the rotation of the reel 10' its own axis of this fresh example, by the movement of roll 11 with the web W, as for the web by tact with the fresh roll.
The web ismaintained at proper speed, that is web speed, by belts 14 running on pulleys 15 and operated from the press as usual at web speed. These belts and pulleys are mounted on a swinging frame 16 which is held in position by gravity and moved back and forth by the web rolls in a well known manner, but the belts are always kept close to the web by this means.
For the purpose of severing the Web when it passes from the expiring roll 17 and has just been pasted to the new roll 11, I
. means of a brush 13, or other means, into conprovide a sharp blast of air emerging from under a heavy pressure in a thin line against the web at its two edges and in fact practically all the way across the same, but the direct and heaviest pressure is at the edges.
The two" nozzles shown herein are each controlled separately by their own valves 21 and each valve is actuated by a solenoid 22 which is connected by a wire 23 with a commutator 24 on the axis of the roll 11 rotating with it. There is a push button or switch 25 in this line which is normally opened but which can be closed just before the paster is to be made. Then when the roll 11 is rotated around to the proper position for making the paster, the circuit 23 will be closed coming through a pipe 26, to impinge against the web in a straight line across it as indicated more especially in Figs. 2 and 3.
These blasts of air are so sharp as to sever the web straight across the same. The pushbutton, or other circuit closing means, is then opened until it is desired to use this mechanism again.
It will be observed that the nozzles 20 swing out of the way together with the belts roll to it, of means 14 whenever the reel is rotated. The shape of the nozzles is such as to virtually cover the entire width of the web with one or more shots of air under pressure in the form of blasts. The web is severed straight across instead of the usual ragged manner.
This eliminates the dangerous effects which the ragged breaking, heretofore employed, frequently had on an otherwise successful pasting operation. Many such pasters have been spoiled by the wrapping around one of the several rolls of a long irregular tail of paper caused by the ordinary severing device.
Although I have illustrated and described only one form of the invention I am aware of the fact that 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 these respects but what I do claim is 1. The combination with means for guiding a web and means for pasting a new web roll to it, of means for pro ecting compressed air against the expiring end of the old web at both edges and across the web in a straight line and constituting the sole means for severing the web.
2. The combination with means for guidin a runningyweb, of an air nozzle on each si e of the web at a distance from the guiding means having a long narrow outlet 0 ening arran ed transversely across the we I in a straig t line at a point where the web is sup ported behind it, and means for connecting the nozzles with a source of air under ressure to project long narrow jets 0 air against the web and sever it in a straight line thereacross.
3. The combination with means for guiding a web, and means for pasting a new web roll to it, of means for pro]ecting compressed air with a heavy pressure against the edges of the expiring end of the roll web and with a lesser pressure across the width of said expiring end, thereby to sever the web in a straight line.
4. The combination with means for guiding a web, of means for projecting compressed air with a heavy pressure against the edges of the expiring end of the web and with a lesser pressure across the width to sever the web in a straight line.
5. The combination with means for guid ing a web and means for pasting a new web for pro ecting compressed air against the expiring end of the old web at its edge and across the web and constituting the sole means for severing the web.
In testimony whereof I have hereunto'act- K fixed my signature.
