5 Claims.

'My'invention relates to a web splicing device and this application is a division of application Serial No. 22,789 filed by me on May 22, 1935 for R011 handling mechanism,-now' Patent No. 5 2,075,192, March 30, 1937.

The present invention relates to a device located between means for supporting rolls of paper and a machine, such as a corrugating machine, by which the web of paper from the rolls I is utilized.

One object of my invention is to provide means for splicing the end of the web of one roll to that of another, thus rendering the operation involving the use of the web substantially continuous.

Another object of my invention is to so construct the splicing mechanism as to provide compensating means for securing true running of the sheet or web which might otherwise be interfered :0 with by inequalities of the roll.

.A further object of my invention is to provide the splicing device with tension regulating means for the web.

In the accompanying drawings, which illustrate one form of web splicing mechanism made in accordance with my invention, Figure 1 is an end view, the brake and sprocket drive being omit ted; Figure 2 is a top plan view; Figure 3 is a section taken on the line 3-3 of Figure 2; Figure 4 is an enlarged detail view, partlyin section and partly in elevation, showing the spring adiustments; and Figure 5 is an enlarged section taken on the line 3-3 of Figure 1 v The mechanism comprises a pair of similar 5 side frames 6 and :I connected by atie rod-3. 'Blidingly mounted in each of the side frames is a bearing block 9 in which is journaled the shaft id of the main roll ll. Each frame has slidingly mounted in it at each side ofblock 3 a 9 bearing block l2 in which are iournaled the shafts l3 of the side rolls N. Roll II is provided at the end adjacent frame 6 with a gear wheel II. This wheel meshes with gear wheels "on rolls It so that the three rolls are positively driven at the same peripheral speed.

The bearing blocks II are biased towardthe main roll by coilsprings t1, the ends of which extend into sleeves I! having threaded engageo ment with the frame and provided with'hand wheels l3 by means of which they may be rotated to vary the tension of the springs. After adjustment of the spring tension, the sleeves are secured against rotation by' lock nuts 23 actuated 5 means of handwheels 3i.

(Cl. it'll-2.1)

The shaft it of the main roll extendsbeyond frame 3 and is provided with a sprocket wheel 22 connected by sprocket chain 23 with a sprocket wheel 24 on the outer end of a stud 25. This stud is journaled in a bracket 26 and has mounted et 35. A treadie 36 carried on the outer end of the rock shaft is normally held in raised position by a coil spring 31 interposed between the treadie and a bracket 33. While the treadie is held in raised position by the spring, bevel gear will moved into engagement with gear 21 so that the rolls will be positively driven from shaft 28 which is supplied with power fromany suitable source (not shown). g

It is desirable that the tension of the web be maintained constant as it passes to the machine utilizing the said web. While a uniform retarding efl'ect may be imparted to the paper rolls by suitable braking mechanism on the roll supporting means, the tension of the web itself will vary v due to the changing diameter of the roll as-it unwinds. ,1, therefore, provide the rolls of my splicer with braking means, supplementary to that of the paper roll support, for securing such uniform tension. Any desired form of retarding device may be employed but I prefer to use the friction brake shown. The end of shaft in is provided with a drum 39 forming the inner part of the brake. The outer part comprises'two semiannular members 40 and ll surrounding the drum. The parts 40 and ll are pivoted together at 42. At the opposite side of the brake a threaded rod 43 is pivotally attached to part ll carried by frame 6 and engaging lugs 48 on part 4|.

lows: When the end of the web of paper from one roll is reached, a second roll is, brought into position by any suitable means, such, for example, as that described in my above mentioned application. The leading end of the new web is brought up to roll l5, pasted and applied to the rear end of the first web. As the superimposed webs pass between the rolls they will be pressed together, thus setting the paste; To take the strain off the pasted splice, the brake is released by means of handwheel 44 and treadle 36' is depressed to positively drive the pasting rolls at the same surface speed as the machine being supplied with paper. As soon as the splice enters the machine utilizing the web, the treadle is released. During the operation of the machine the web may tend to run untrue due to inequalities of the paper roll or other reasons. This tendency may be counteracted by varying the tension of one or more of springs i1 through the action of the hand-wheels l9. This will move the sliding

bearings

9 and 12 to slightly cant the rolls in the proper direction to correct the untrue running.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A splicing device comprising a plurality of rolls, sliding bearings in which said rolls are mounted, springs controlling the pressure between said rolls, said rolls being connected by gearing, a brake for retarding said rolls, means for varying the tension of said springs, driving mechanism for said rolls, and a clutch device for throwing said driving mechanism into and out of operation.

2. A splicing device for webs comprising a frame, a main roll, main bearings slidingly mounted in said frame in which bearings the main roll is mounted, a pair of side rolls between which and the main roll the web passes, side bearings slidingly mounted in the frame in which bearings the side rolls are mounted, all of said bearings being movable in a direction transverse to the path of the web between the main and side The operation of my device is briefly as 101-.

rolls, and means for biasing each of the side bearings toward the main bearings, said means being independently adjustable, whereby all the rolls may be simultaneously canted to correct untrue running of the web.

3. A splicing device for webs comprising a frame, a main roll, main bearings slidingly mounted in said frame in which bearings the main roll is mounted, a pair of side rolls between which and the main roll'the web passes, side bearings slidingly mounted in the frame in which bearings the side rolls are mounted, all of said bearings being movable in a direction transverse to the path of the web between the main and side rolls, springs biasing each of said side bearings toward the main bearings, and means for independently varying the tension of said springs to simultaneously cant the rolls to correct untrue running of the web.

4. A splicing device for webs comprising a frame, a main roll, main bearings slidingly mounted in said frame in which bearings the main roll is mounted, a pair of side rolls between which and the main roll the web passes, side bearings slidingly mounted in the frame in which bearings the side rolls are mounted, all of said bearings being movable in a direction transverse to the path of the web between the main and side rolls, gearing connecting said rolls, a brake device for retarding the rolls, springs biasing each a of the side bearings toward theimain bearings,

and means for independently varying the tension of the springs to simultaneously cant the rolls to correct untrue running of the web.

5. A splicing device for webs comprising a pair of frames, a pair of rolls between which the web is pressed, said rolls being journaled in bearings mounted to slide in said frames and to be capable of limited angular movement therein, and means for controlling said angular movement whereby both rolls may be simultaneously canted in a direction transverse to the path of travel of the web between them to correct untrue running of the web.
