Renewed August 10, 1935 1 Claim.

This invention relates to the supporting and operation of fresh web rolls for splicing a runmng web thereto and manipulating the rolls to get them into proper position for the splicing operation.

The principal objects of the invention are to provide convenient and simple means for operating these heavy rolls to move them bodily from one position to the other, preferably acting in connection with means for speeding up the roll which is normally inactive, and means for splicing the roll to a running web.

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 showing a preferred embodiment of this invention in inactive position;

Fig. 2 is a similar view showing the lifting of the fresh web roll into splicing position;

Fig. 3 is a similar view showing the placing of the web roll in running position;

Fig. 4 is an end view showing a modified structure; and

Fig. 5 is a similar view showing the parts in a different position.

Thedevelopment of an apparatus for splicing the surface of a running web roll to a Web running at a very high speed for newspaper printing presses has necessitated the provision of substantial working means for manipulating the heavy web roll to bring it into position for splicing. This invention relates to that type of web replenishing devices, in which the new web roll and running web are brought adjacent to each other and the web roll is brought up to web speed by normally inactive but preferably press-driven means acting on its surface, although the principle of the invention shown herein can be used with means for rotating the web roll from its axis.

In the first form illustrated is shown part of a stationary press frame Ill having bearings II thereon in which is rotatably mounted a screw shaft I! which is driven by gears I3 by a motor or any other desired source of power. Ome of these vertical shafts is located at each side of the press at the rear thereof and they carry a pair of nuts M, each having a socket l5 for receiving the shaft or studs is of a web roll l1. This is the running roll.

For the purpose of supporting a fresh web roll and transporting it to the splicing position and the running position shown in Fig. 1, the following mechanism is provided. A shaft 29 driven by a motor or other source of power is provided I with a worm 2i, first in one direction and then in the other. This oscillates a worm segment 22 fixed on a shaft 23 which is provided with two arms 2 located at opposite sides of the press. These arms constitute a frame and have sockets 25 for the purpose of engaging the stud l6 of a web roll and moving it. This is shown in inactive position in Fig. 1, but in Fig. 3 the segment 22 is turned so as to bring the sockets 25 into position to lift the new web roll 26, and in Fig. 2 it is shown in pasting position.

In this figure is shown an endless speedingup device 21 movably mounted by means of a pair of arms 28. This speeding-up device is normally inactive but preferably press driven to operate on the surface of the roll 26 and to bring it up to the speed of the running web W. Also in Fig. 2 is shown a pasting member 29 which is operated by a worm 30 receiving its power from any desired source to press the web against the roll 26.

After this is accomplished, the arms 24 are raised to the position shown in Fig. 3, when the studs l6 of the roll are directly over the sockets I5. Then the screw shafts I2 are turnedto bring the sockets 15 into position to support the studs and the roll. After this the arms 24 are drawn downwardly, leaving the roll supported as shown in Fig. 1.

It will be understood that the roll 26 is moved up to the position shown in Fig. 2, the driving means 21 applied to its surface and the roll rotated to web speed. Then the pasting device 29 is brought down on the web coming from the new nearly exhausted roll H, which is moved down to the position shown. Of course, the roll 26 is previously supplied with spots of adhesive in any of the usual ways and the roll ll is moved down to a position where the web W from it going over a guide roll 29a, will be close to the surface of the roll 26. This feature of getting the web close to the surface of the new roll can be accomplished by the movement either of the exhausting roll or the new roll or both.

In the form shown in Figs. 4 and 5, a construction is shown for the same purpose, in which the new roll 26 and the running and nearly exhausted roll l! are mounted on independently movable oscillating frames 3! and 32 made up of arms which are fixed to shafts 33. Each shaft is operated independently by power through a worm 34 and segment 35, the latter being fixed to the shaft 33. In this case the roll propelling devices 27, one for each roll, are mounted below but have the same characteristics, being normally inactive and adapted to be connected with and operated by the press when needed. The web pressing devices 29, of which there is one for each half of the machine, are operated in any desired way. Starting from the position shown in Fig. 4, the frame 3| is moved up to the dotted line position and the roll propeller 2'! is moved up to the roll so that the web W runs close to the surface of the new roll. Or, the frame 32 can be moved up to the roll 26. The splice is made in the same way practically as above described in connection with Figs. 1, 2 and 3. In Fig. 5 the next operation is shown in which the roll above described being spliced to the web has become nearly exhausted and the new roll is being rotated on the frame 32.

In all these forms it will be seen that means is provided for supporting one or both of the paper rolls in connection with a normally inactive means for speeding up the incoming roll, and means for forming the splice. These devices in general constitute comparatively simple mechanism for performing these functions and stable strong means for supporting the heavy roll.

Although I have illustrated and described several forms of the invention, I am aware of the fact that other modifications can be made therein without departing from the scope of the invention as expressed in the claim. Therefore, I do not wish to be limited to the forms shown herein, but what I claim is:--

In a web splicing device, the combination with means for guiding the web from a running roll to a printing press, of means for supporting a new web roll in close proximity to the running web, normally inactiye, means for rotating the new web roll at web speed, means for bringing the running web and the new web roll into contact, positive means for moving the contact making means against the web and means for lifting the fresh web roll directly from its point of support outside the mechanism and moving it toward the running web in an upward. course all the time.
