It is common practice in the paper making art-to carry out coating or treating operations such as waxing or parchmentizing or finishing as continuous operations on a web of suitable Vstock paper and the stock paper is supplied in separate rolls .so that Athe `trailing end of one roll Vof stock must be spliced to the leading end of .a second roll of stock. It is further old to make .these Vsplices while the machine is operating and withoutstopping the continuous delivery of the paper stockto the treating or coating machine. In making .this splice without .stopping the delivery of the stock web a replacement roll of stock is torn to provide a tapered tongue or tab `on the leading end of the replacement stock and .this -tab is temporarily Vsecured to the outside of the replacement roll and coated with adhesive on the outside of the tab. The replacement roll is then rotated at the same peripheral speed as the lineal speed of .the web advancing from the old roll of stock and the replacement Vroll is advanced into contact with the moving web near Ithe Vend of the old roll. The adhesive tab on V-the new roll is picked up by and adheres to the old web `and is advanced with it into the treating machine so that the tapered -tongue feeds into the -machine along with the old web until the full 'width of the new roll of lstock is threaded iinto the machine along withthe trailing end of the web von Ythe oldroll of stock. Inorder to minimize the length fof the stock'that is of double thickness the web of the old `roll may -be cut as ysoon as :the full width of thenew roll of stock `is threaded into the machine.

The features of thepresent machine which perform the foregoing splicing operation include a frame 1 having relatively heavy and rigid side members V2. Supported along the tops of the side members is a first set of slideway forming members 3 3 having llattened slideways 4 `on `their top and forming a trough like openingfor recess 5. .A second set of slideway forming members 6 are secured at the tops of the side frames and along the inner sides thereof below the level of the slideway members .3. .The slideway members 6 have similar slide surfaces 7 'on the top and form upwardly opening U-shaped recesses 8.

A iirst pair of slide members 9 are slidably supported on the slide surfaces 4 of the slide members 3. The .slides 9 receive .and support upwardly opening transversely extending bearings 10;for rotatably supporting the transversely extending core shaft 11 of a irstpaper stock roll 12. The other set of slideway members 16 support similar slides 13 that vsupport bearings 14 for rotatably supporting a second core shaft 15 zof a second roll Aof stock 16.

v'Extending'longitudinally through the .channel recesses 5 `in the first slideway members 3 are elongated screw elements 17 rotatably supported Vin bearing plates 18 at the end ofthe frame. A similar Vset of screw elements '19.are lpositioned'in the recesses i8 in the second set of slideway members 6. Each .ofthe screw elements l17 and 19 carries a travel nut 20 having a squared upper side 21 (see Figs. 8-10) ythat fits into a notch 22 in the underside of the slide members 9 and 13 mounted on the slideways. VRotation of the screw elements thus functions to move the slide members .and the .bearings supported therebyalong the slideways.

The forward ends of the screw elements 17 are connected through gearboires 23 (see Fig. l) with a cross shaft 24 and a drive motor 25 for Simultaneously moving core shaft 11 forward or lbackward along the frame. rI he forward ends of the screw elements19 areeonnected through gear boites 26 with a second cross shaft 27 and a motor 28 for similarly moving the secondfcore shaft 1S. Withreference to Fig.'3 it will be noted that the bearings and 14 and the core shafts 11 and 15 supported thereby are in clearing relation so that the shafts can be moved forwardly and rearwardly past each other on the machine as desired. The yoke l29 carrying a screw 30 and friction brake block 31 on one o f the bearing supports is readily removable to permit advancement of the 'core shafts.

Mounted on the inside of ca chside member 2 of the frame is a support arm 32 pivotally supported in gen- 'erally upright position on the shouldered bolts 33. The

upper swinging ends of the support arms 32 rotatably and movably support a cross drive shaft 34 having a Y vdrive roll 35 connected thereto midway between the side 'members of the frames. ljects through holes provided therefor in the side member One end of the shaft 34 proof the frame and carries a sprocket 36 adapted to be driven by the chains 37 at the same speed as the paper treating machine 38 with which the splicing machine is associated. Movement of the support arms 32 on the pivot bolts 33 is limited as will be described so relatively small holes 39 in the side frame permit sufcient moveis supported at its ends on crank arms 55 pivotally mounted on the side members 2 of the frame. The pivot 56 which supports the crank arm may also support a guide roll 57. Brackets 58 mounted on the side frame carry pneumatic cylinders or bellows 59 having piston rods 60 connected to the cranks 55 for pressing the pressure rolls against the drive roll.

The web of stock from the-first roll 16 is trained around the drive roll from a position near' the forward ends of the slideway members as is best shown in Fig. 2. This leaves space for the mounting of a second stock roll 12 between the side members and rearwardly of the drive roll while the stock is running out from the first i roll as will be understood. During running out of the ment of the shaft 34. The driven roll 3S performs the `dual function of both guiding the web of paper from the `roll 16 and also pulling or feeding oi the web from the roll. If other paper pulling or feeding means are provided the roll 3S may function solely las a paper guide.

and need not rotate.

Rotatably mounted on the drive shaft 34 `between the support means 32 and the ends of the drive roll 35 are a pair of depending hanger arms 40. Desirably bearings 41 are retained in recesses in the hanger arms by end plates 42 (see Fig. 7) 'so that the hanger arms are freely rotatable on the drive shaft 34. The lower swinging ends ofthe hanger arms rotatably support a starter roll shaft 43 which thus extends in spaced parallel relation to the drive shaft 34 and drive roll 35. One of the hanger arms '40 carries an idler gear 44 that is meshed with va drive surface of a new stock roll as will be described.

The forwardA sides of the hanger arms 40`are'provided with brackets 4S to which the piston rods 49 of pneumatic cylinders 50 are pivotally attached. The forward ends of the cylinders 50 are pivotally connected at 51 (see `Fig. 2) to a forward member of the frame 1. vAsY will be seen from a comparison of Figs. 2 and 5 extension of the piston rod 49 will swing the starter rolls 47 upwardly into driving engagement with the new roll l of stock 12.

The weight of the starter shaft 43 and starter rolls 47 is relatively heavy and this weight is supported in lpart by the action of the piston rod 49. The weight is also applied through the hanger arms 40 to the drive shaft 34 at a point rearwardly from the pivot pins 33 so that the Vdrive shaft 34 is weight biased rearwardly on the support .arms 32. In order to limit rearward rotation of the support arms 32 the side members 2 of the frame are pro- 'vided with stop blocks 52 that engage the support arms to locate the drive shaft in the desired normal operating position.

'Ihe web of paper from the first or old roll of stock 16 is trained around the drive roll 35. In order to provide a driving engagement between the weby and the drive roll there is provided a pressure roll 53 having oppositely spiraled rubber ribs 54 on the surface. The pressure Ioll first' roll the pressure of the pressure roll 53 is adjusted by control of the cylinder 59 and a control element 61 for regulating the pressure in the cylinder is indicated in, Fig. l. Concurrently the new roll of.stock 12 with its splice tab 62 prepared and coated with adhesive as at 63 is advanced forwardly to adjacent the drive roll by actuation of the motor 25 through its control buttons 64. Prior to bringing the new roll 12 into contact with the drive roll the operator actuates the pneumatic cylinder 50 by operation of the control 65 to raise the starter roll 47 into driving engagement with the surface of the new roll as appears in Fig. 5. This starts the new roll rotating in its bearings after-which the new roll is moved forwardly until it contacts the driving roll as shown in Fig. 4. The splice connection is made in the well known automatic manner and as soon as the splice is complete the old web may be cut by a knife 66 supported by the bell cranks 67 on the sides of the frame. Pneumatic cylinders 68 operate the knife and are controlled by the control elment 69 on the control panel.' 1'

In the event that the operator does not stop forward motion of the new roll 12 at the correct time the pressure of the new stock roll 12 on the drive roll 35 will move lthe support arms 32 away from the stop blocks 52. One of the stop blocks carries a safety switch 70 (see Fig. 6) Vthat opens when the drive roll is moved forwardly. The switch 70 is connected in the energizing circuit of the motors 25 and 28 to automatically stop further forward feeding of the new stock roll. The circuit for driving the motors rearwardly is independent of the switch 70 so that the screws can be reversed to back the roll of stock away from the drive roll. I

It will be noted that either the bearings 10 and the slide members 9 or the bearings 14 and the slide members 13 are voperative to advance the new roll of stock to an exhausted -roll supported on the other set of bearings and slide members. After the splice is complete the exhausted roll and its core shaft are removed from the splicing machine and the then empty slide members, either 9 or 13 can be retracted by screws to the opposite side of the full roll of stock to ready the machine for another new roll Vof stock. As each new roll decreases in size until it can clear the drive roll 35 it is moved forwardly to make room for the succeeding roll. Desirably limit switches 71 are mounted at the ends `of the slideways 4 and 7 for actuation by the slide members 9 and 13 and connected in the energizing circuits ofthe motors 25 and 28 to prevent over travel o'f the slide members.
