18 Claims.

The present invention relates to web renewing apparatus and more particularly to novel and improved mechanism for bringing the reserve web roll up to the speed of the running web preparatory to effecting a flying paster.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings:

Figure l is a side elevation of the present preferred and illustrative embodiment of the invention, certain of the parts being shown diagrammatically.

Figure 2 is a side elevation of the mechanism shown in Figure 1 with certain parts broken away.

The present invention has for its object the provision of a novel web renewing apparatus. A further object is the provision of a simple, inexpensive and easily operated means for bringing a reserve web roll up to the speed of the running web. Another object is the provision of a single motor means which can be successively placed in operative relation to successive reserve web rolls as they are brought into pasting position. Still another object is the provision of compact reserve roll rotating means carried by the magazine reel.

In accordance with the present invention, the web rolls are rotatably supported so that the reserve web rolls may be brought up to running speed by a motor driven friction member, joined to the running web and then moved into running position, this operation being repeated with successive web rolls without necessarily stopping the running of the web to the printing press or other web using machine. The motor driven friction member is mounted on the web roll supporting means and may be brought into engagement with successive web rolls in pasting position.

It will be understood that the foregoing general description and the following detailed description as well are exemplary and explanatory of the invention but are not restricted thereon.

Referring now in detail to the present preferred and illustrative embodiment of the invention as shown in the accompanying drawings, the web roll supporting means comprises a conventional form. of magazine reel in which the running web 60 roll and reserve web roll or rolls are rotatably supported and by which successive web rolls may be brought into pasting, and then running position. As embodied, the multi-armed web roll supporting members 1 are spaced apart to receive the rotatable web rolls A, B and C between them, and the supporting members 1 are rotatably mounted on side frames 2 by means ofshaft 3. The details of'this mechanism, including the web tensioning devices, side registering devices and reel arm rotating mechanism are not shown as they form no part of the present invention.

As shown, web roll A is the running roll and is in running position; web roll B is a reserve web roll in pasting position; and Web roll C is a spare roll which will be successively moved into pasting, and then running, position by clockwise (Figure 1) rotation of the web roll supporting arms. Although shown in connection with three web rolls, any other desired number of rolls may be employed.

The means for bringing the'web roll to the speed of the running web, so that the leading end of the reserve web may be joined to the running web while the running web is being supplied to the press, comprises an electric motor which may be successively placed in operative position with respect to successive web rolls, and may be coupled thereto by a friction disc driven by the motor.

The electric motor may be of any desired type having sufficient power and speed for the purpose, but I prefer to employ a motor 4 which is capable of withstanding considerable overloads. At the inner end of its shaft, motor 4 is provided with a rubber-surfaced friction disc 5 95 adapted to contact with the surface of the reserve web roll at one end of the roll, and is maintained in contact with the web roll until the paste r is made. Preferably disc 5 contacts with the roll very close to its end, out of line with the glue ap- 100 plied to the leading end of the reserve web. I

Means are also provided for supporting the motor,'pressing it into engagement with the reserve web roll and for permitting successive reserve webrolls to be moved into pasting position. 105 As embodied, the motor 4 is slidably mounted on an arm 6, by means of a plate 7 which is dovetailed into a head 8 at the outer end 'of the supporting arm 6. A lever 9' is pivoted on said head and connected with the plate 7 by means of link 110 10 tomove the motor axially of the web rolls. Arm 6 is pivotally mounted around the reel shaft 3, and is held against longitudinal movement thereon by means of a spacing collar 11, and the hub 12 of the web roll supporting arms 1.

For pressing the friction disc against the surface of the web roll and maintaining it in contact therewith until after completion of the paster, arm 6 is formed with a radially extending portion 13 to which is secured a variably positionable weight 14, heldin the desired position on said portion by means of the set screws 15. Weight 14 tends to cause a clockwise (Figure 1) rotation of the arm 6 and motor 4, maintaining motordriven disc 5 in engagement with the surface of the web roll B during the movement of the web roll from pasting position. Weight 14 may be moved radially on portion 13 to give the necessary pressure between the friction disc 5 and the web roll B.

For varying the speed of the motor, so that the reserve web roll will be drivenat the speed of the running web, a variable resistance 16 may be provided in the motor circuit, permitting the operator to control the power supplied to the motor.

The operation of the above described device may be summarized as follows:

With the parts in the position shown in the figures of the drawings, the motor 4 is started when the web roll A is partially exhausted and continues to run until the reserve web roll B is brought up to speed and the paster has been made. The leading end of the web roll B has the usual pasting glue applied to it and a pasting roller 17, mounted in the pivoted arms 18,v is moved to press the running web against the surface of the web roll B, thereby picking up the leading end of the reserve web and effecting the joinder of the reserve web to the running web. The old running web is then severed in the usual manner, and the web supporting arms 1 are rotated to bring the reserve web roll B into running position. While this rotation is taking place, weight 14 moves the motor 4 to keep friction 'disc 5 in contact with the web roll B, until just before the web roll is fully moved to running position.

During the rotation of the web roll supporting arms 1, the web roll C has been moved to pasting position, and the motor 4 may then be moved axially outward to permit arm 6 to be swung counterclockwise (Figure 1) so that motor 4 may be moved inwardly to contact disc 5 with the surface of the web roll C. The motor remains idle in this position until the running web roll is sufficiently exhausted indicating the time for startning web roll and a reserve web roll and amotor having on its shaft a friction member to be moved into engagement with the reserve web roll to bring it to running speed.

2.
