y 1933. H. A. w. WOOD QUICK CHANGE SPLICING DEVICE Original Filed June 4, 1927 w /WWM' Patented May 16, 1933 UNITED STATES PATENT oFrice HENRY A. WISE WOOD, on NEW YORK,

N. Y., ASSIGNOB TO WOOD NEWSPAPER MACHINERY CORPORATION, OF NEW YORK, N. 'Y., A CORPORATION OF VIRGINIA QUICK CHANGE SPLIGING DEVICE Applicationflled June4, 1927, Serial This invention relates to a pasting device for the web of a continuously operating printing press.

The principal objects of theinvention are to provide a single propelling means for propelling the expiring web roll up to the time of the severing of the web and for propelling the fresh web roll previously pasted and get it up to web speed before it is attached to the web, and to provide means for getting the fresh web roll up to web speed and continuing to rotate it as long as the web isconnected with it without changing the propelling-device or shifting its engagement w1th the web roll from the time it is a fresh pasted roll to the time it is an expiring roll stub. This obviously results in the reduction of mechanism and expense due to the fact that a single propelling device is used for the fresh and expiring rolls instead of one for each one as has been the case heretofore.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which Fig. 1 is a diagrammatic side view of a set of web rolls showing-my new method of propelling the running roll throughout the time of feeding a web therefrom to the press;

Fig. 2 is a similar view showing the use of the same propelling means for starting. the fresh roll .and getting it up to web speed without losing its control of the running or expiring roll; 1 f

Fig. 3 is a similar view showing the position of the parts after the *fresh roll is pasted to the expiring web and the latter severed;

Fig. 4 is a. similar view showing the removal of the core of the expiring web roll and the commencement of the running of the web from the fresh roll, the parts being ready to shift back to the position shown in Fig. 1; and

Fig. 5 is a side view of the fresh web roll pasted and illustrating the propelling belts.

According to this invention, the web W is run to the press over a guide-roll G from a running web roll A. This running web roll REISSUED No. 196,517. Renewed March a, 1933.

provided with paste P in the usual manner. I have also shown an inecoming roll C which will later take the place of the roll B when that takes the place of the roll A in the position just beyond that shown in Fig. 4.

For the purpose of propelling the running roll A and the fresh roll B, I provide a series of driving belts D. These are indicated in these figures as running over pulleys on two shafts d, one of these shafts being in stationary bearings, and the other being mounted to move toward and from the fresh roll B. The stationary shaft is operated from the press at such a rate as to drive the belts at web speed. This movement above mentioned is indicated by comparing Figs.

v1 and 2, in which the belts D, always in contact with the running or expiring roll A, move into a position in Fig. 2 in vwhich they also engage the surface of the fresh roll B and rotate that soas to bring it up to web speed. After this is accomplished, the web W and the fresh roll B are brought toward r each other by moving. one or the other as may be desired. In the present instance, by comparison of Figs. 2 and 3 it will be seen that the roll B has been moved up to the web. Furthermore, a means for pressing the web against the fresh roll, shown as taking the form of a brush E, has been moved up so that the expiring end of the web will be forced against the paste'stops P on the web I roll B. Immediately afterwards, the'severing knife F is brought into contact with the web and that is severed from the expiring roll or stub as shown in'Fig. 3. Now the expired roll or core A is removed as shown in Fig. 4, the knife F is drawn back and also the brush E. During all this time the belts D have been running the roll B at web speed. From the point shown in Fig. 4, the roll B becomes the running roll and eventually the expiring roll. The roll C is moved into the position of the roll B to become the fresh roll. at the desired time. It will be understood that the driving belts D can be moved as described or the fresh roll B can be moved so long as they are brought together. I have not shown the means for moving these parts as they constitute the fea tures of an independent invention. It will be seen that in all these cases the expiring or running and fresh rolls are driven by a single means constituting a plurality of driving belts rotated by the power from a single shaft. There is no loss of control when a fresh roll becomes the running roll. The only thing necessary to perform the above-mentioned functions is to move this set of belts or the rolls to be driven thereby.

This constitutes a simplified method of bringing the fresh roll up to the web speed and keep the running and expiring roll running at web speed all the time. Furthermore, by having only one driving means,

' there will be no possibility of the two ro-lls getting out of step with each other or being propelled at two different speeds.

Although I have illustrated and described only a single 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 to all the "details of construction herein shown and described, but what I do claim is 1. In a quick change splicing device, the

' combination with a running roll and a fresh roll for the web, of a moving member running at a constant speed and engaging the two rolls at different points on its periphery and thus running the two rolls at exactly the same sun face speed, said moving member being connected with the press to be operated thereby.

'2. In a quick change splicing device, the combination with a running or expiring roll for the web, and afresh web roll, of a series of propelling belts engaging the surface'of the running or expiring roll at all times while it is connected with the running web and engaging the surface of the fresh roll to run the fresh roll at web speed for a material period before going out of contact with the surface of the expiring roll, said belts being movable out of contact with'the expiring roll at about the time which the web is severed therefrom.

of contact with the surface of the expiring roll until the web is severed.

' 4. In a web splicing mechanism, the comrooaata thereto and to continue to propel it until it is nearly exhausted, said belts being movable to accommodate the roll in its splicing and running positions, and engaging the surface of the expiring web roll at all times while it is delivering the web and the surface of the fresh roll without going out of contact with the surface of the expiring roll while the latter is operating and then passing out of contact with it. g

5. In a quick change splicing device, the combination with a running roll and a fresh roll for the web, of a propelling belt running at a constant speed ratio and simultaneously engaging the two rolls at different points on its periphery, said propelling belt being connected with the press to be operated thereby.

6. The method of splicing a web. which consists in-runn'ing a surface at web speed in contact-with the expiring web roll to r0- tate said web roll, then moving said surface until the rollis nearly exhausted, then bringing said belt into contact with the fresh web roll, which has been pasted, to bring that up to web speed, moving the fresh web roll to bring it into contact with the web, forcing the web against the fresh Web roll, severing. the web, and removing the exhausted stub from contact with said web, leaving the fresh web roll tov becontrolled by the belt.

In testimony whereof I have hereunto affixed my signature.
