RY PAS'I'ING DEVICE w zirl zeay "1. Y A. WJJEE WOOD, OF NEW YORK, N. Y., ASSIG-NOB T WOOD NEWSPAP 1 BSA- manna CQRPDEATIUN, OF NEW YORK, 31'. Y., A CORPORATION 05 VIEGIIM ROTARY TASTING: DEVICE Application filed January 26, 1927, Serial No. 163,654. Renewed Play 2, 1.928.

This invention relates to an improvement over the pasting mechanism shown and described in my prior application for patent Serial No. 42,061, filed July 7, 1925, on a a Web change device.

The principal object of this invention is to provide a pasting or deflecting device for the web which deflects the web against a fresh web roll at the time of pasting, as in in my above mentioned application, but in such form that it will ofier no resistance to the running of the web and therefore will not cause any strain thereon.

This invention can be used with the type of pasting device set forth in the above mentioned application and is intended for such use particularly. But it is to be understood that it is merely one feature thereof which can be used with other forms of web pasting mechanism. Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is a side view, partially diagrammatic, of a web change device such as shown in my above mentioned application with a preferred embodiment of this invention applied thereto; and

Fig. 2 is a similar view showingthe parts 4 in another position.

In the web change mechanism shown in my above identified application, a deflector is used in the form of a brush which is located in stationary position apart of the time in contact with the running web. Then the brush is lowered into pasting position and deflects the running web into contact with the fresh web roll. This, together with the usual provision of the pasted area on the to fresh roll, performs the operation of attachin the new web to the end of the expiring we b, the tail of the expiring web being cut away as is well understood.

Referring now to the drawings it will be seen that l have illustrated several features shown in my above mentioned application. It will be understood that the running web roll A, the fresh web roll B, and the third web roll C which is to become the next fresh roll, are mounted on a reel 58 which turns about a central shaft 50. The running web roll A in Fig. l is delivering the web W to the press over a spring-pressed idle guide roll 51 and a web control roll 52 operated positively from the press. The web is pro- 5- pelled by a series of feeding belts 53. The web travels uniformly and asses into contact with a deflector in the fiirm of a rotary brush 5-1. This figure shows the normal path of this web during the run, the brush constituting a guide for it at this time.

The mechanism above described is connected with and operated by the press. For example, the shaft of the web control roll 52 is connected with the main shaft of the press and operated continuously at such a rate that its surface rotates at web speed. The other end of the shaft is provided with a sprocket wheel which drives a chain connected with a sprocket wheel on a shaft 61 for driving the latter. On this shaft 61 are pulleys 63 on which are the feeding belts 53. The shaft 61 also, by means of a sprocket wheel, drives another chain 64 which in turn drives sprocket wheels 67 on two shafts 66. This chain 64 also passes over a sprocket 68 mounted on the shaft of the rotary brush 54. Two idlers 69 engage the chain 64 and keep it wrapped well around the sprocket 68. These idlers are located on two links 70 which carry the brush shaft. They are pivotally connected with an arm 94.

The shaft 61 is provided with means for rotating a cam shaft 81 when connected with it by manual means comprising a handle, not shown.

On this shaft 81 are two cams 88 each having a groove 89 provided with a depression 90. In each cam groove operates a roller 91 on an arm 92 fixed on a shaft 93 and having an arm 94 projecting therefrom at each end. It is on these arms 94 that the links 70 are pivoted.

Operation This device operates in substantially the same way as my above identified a plication, or at least it is preferred that it used in connection with the same kind of a machine. The normal position of the partsis shown in Fig. 1 in which the web is being taken off the -web roll A and in which that roll has been reduced in diameter from full size to that indicated. The cam 88 is held stationary and keeps the rotary deflector 54 as shown in that figure during that period. Now when the roll gets a little smaller as shown in Fig. 2 the operating handle, not illustrated herein, is lowered and the shaft 81 starts to rotate and completes an entire rotation of the shaft 81. The roller.91, comin to the lower part of the cam, as shown in ig. 2, will depress the arms 94 and take the frame 70 downward with the brush 5 h This brush has been rotating all the time at web speed so as not to offer any resistance to the web or cause an strain upon it. The same conditions prevail when it is lowered for the pasting operation which takes place in the same manner as de scribed in my above mentioned application. The brush 54 is in contact with the web and the web in contact withthe roll B during a part of one press operation. This applies the free end of the new webon the roll B to the running web A. This running web is later cut oil' by means not forming a part of this invention. The reel 58 is rotated around so that the fresh roll B will eventually occupy the position A. The tapes are moved back and forth by resting against the rolls in accordance with their positions.

This constitutes a simple means for eliminating the slightest strain on the web even at he highest speed. It makes the pasting operation more certain and permits an increase of speed thereof.

Although I have illustrated and described only a single form of the invention, and explained it as used only with the paster shown 4 in my prior application, I am aware of the fact that modifications can be made therein, and that it can be applied to other forms of pasters, 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 deflecting device for a web change "machine, the combination, with means for supporting a running roll and a fresh roll, of a rotary deflector, means for rotating the deflector in contact with the web at web speed, and means for moving the deflector to bring the web running thereover to the pasting point on the fresh roll.

2. In a web change device, the combination with means for supporting a fresh web Y running 'roll to the press, of a rotatable brush.

located in position to engage the web, means for rotating said brush at a surface speed equal to'the speed of the running web, and means for moving the brush bodily toward the fresh web roll for perfog the pasting 0 eration.

4. in a web deflecting device for a web change machine, the combination with means for supporting the web rolls, of a rota brush located in position on the side of t e web opposite the fresh roll, a pair of wheels at opposite sides of the brush adapted to retate freely, a wheel on the brush shaft, means for supporting shafts for the brush and the wheels, a chain or belt passing under said wheels and over the brush wheel for rotating the brush at web speed, and means for moving the support for the brush and wheels bofiily to apply the web to the fresh web ro Y 5. In a web change device, the combination with means for guiding a web from the running roll, of a rotatable soft cylindrical body located in position to engage the web, and means for movin said body toward and into contact with the beyond that at which the web from the running roll engages the fresh roll for performing the pasting operation.

6. In web change device, the combination with means for guiding a webfrom the running roll of a rotatable positively driven brush located in position to and engaging the web, and means for moving said brush toward the fresh web roll for performing the pasting operation. v

7. In a web change device, the combination with means for guiding a web from the running roll, of a positively driven rotatable soft cylindrical body located in position to and engaging the web, and means for movin said body toward the fresh web roll forper ormesh web roll at a point 9. In a web change device the combination withmeans for a web-from a running roll of a rotatable soft cylindrical body engaging the web at all times, and means 5 for moyin said body toward the fresh web roll, and orcing the web gently against the fresh roll for performing the pasting operation.

In testimony whereof I have hereunto- 10 afixed my signature.
