WEB SEVERING AND TRANSFER DEVICE Filed July 29. 1942 3 Sheets-Sheet 3 INVENTORS JOSEPH A. 0on5 [DIV/4K0 Hl/ raw/vs ATTORNEY Patented Feb. 29, 1944 UNITED STATES PATENT OFFICE WEB SEvERING-AND TRANSFER DEVICE Joseph A. Doyle, New Dorp, and Edward Hutchins,

Corinth, N. Y.;

said Hutchins assignor to International Paper Company, a corporation of New York 14 Claims.

The present invention relates to a web severing and transfer device, and more particularly relates to such a device for use in connection with a continuously moving web which is to be wound upon I a plurality of separate reels.

Many forms of machinery are adapted to produes or operate upon a continuous web. Such machinery naturally will'discharge the web in a'continuous operation. In order that the web may be wound in practicable quantities upon separate reels it is necessary to discontinu the winding upon a reel which has received its predetermined quantity and to initiate windingupon an emptyreel without stopping the continuous operation of the web producing or treating machine. For example, in the paper industry a papermaking machine produces a continuous web of paper and under ideal circumstances the machine may not be shut down for several days. Similarly, 'paper coating machines are most efiiciently run in a continuous manner, and to this end paper may be supplied to them from a succession of reels which are so handled as to splice the leading end of a new reel to the trailing end of a spent reel. These splices may be made by any of the well-known flying splicemechanisms and unless it is necessary to stop the machine for the purpose of changing the rewinding reels, the coating operation may be continuously performed. In either of these examples as well as wound upon the reel it is necessary to shift the filled reel while it continues to wind to a'p'osition permitting the insertion of a new empty reel. Normally the web is brought up over the upper peripheral portion of the driving drum and an empty reel is lowered into frictional contact with the upper surface of the web upon the drum.

1 Assuming that the papermaking or other web handling machine has just been startedia certain quantity of the web is permitted to go beyond the empty reel until such time as conditions in the machine have become sufficiently uniform to make it advisable to begin the reeling operation. At this time the web is severed along a line just beyond the empty reel and the leading edge thus formed is directed upwardly around the empty reel. The directing of the web may be accomplished by the use ,of jets of air or water or steam, or ma be accomplished by some mechanical manipulation or even by manual manipulation. Assuming a manual manipulation. the leading edge is gripped by operators at opposite sides of the machine and is thrown up and over the empty reel whereby the leading edge drops down upon the upper face of the web progressing toward the reel. This serves to drag the leading edge into the nip between the winding reel and the driving drum and forms a bight in many other instances it is highly desirable to provide for instantaneous transfer of theweb from one rewinding reel to another- Various reeling devices are known which are capable of handling a continuously moving web. One widely used form is that shown in U. S. Patent No. 1,248,542, granted December 4, 1917, to C. E. Pope, and this particular reeling device is known throughout the paper industry as the Pope reel. The present invention is particularly adapted for use in conjunction with the Pope reel although obviously it is not limited in its use to such a reel. For the purposes of description the invention will be set forth in connection with the Pope reel.

In general the Pope reel comprises a driving drum which is rotated at a peripheral speed equal drum and the leading end of the paper is'secured in some manner to the empty reel whereby rotation of the driving drum will serve'to rotate the empty reel and wind the paper therearound. When a predetermined quantity of paper has been having suilicient friction'to secure. the web to the winding reel. From this point on the web will be progressively wound upon the reel.

'At'an appropriate time the partially wound reel may be moved along the periphery of the driving drum in the direction of rotation thereof and brought to rest in asuitable bearing mechanism wherein it continues to wind in order to accumulate the predetermined quantity of web material.

' In the meantime a new empty reel is brought into position and is suspended just above the driving drum in a position ahead of the reel-upon which the web is being wound. When the predetermined quantity is reached it is necessary to sever the web at a point between the empty reel and the filled reel and it is necessary to direct the leading edge of the web around the empty reel to initiate winding upon the same.

With many grades of paper the various forms of manipulation mentioned above are satisfactory. However, when an extremely heavy web, as for example a paper board, is being handled or ineffective. Many expedients have been resorted to, but in many instances it has been found to be 5 necessary to stop the machine each time a winding reel is changed. In the case of a coating machine the whole machine may be stopped, and certain portions of the web will necessarily be improperly coated and/or dried. In the case of a papermaking machine, the problem of stopping the machine is so great that the normal pl'ocedure is to sever the web somewhere ahead of the winding station and to permit the web to be wasted during the time necessary to eifect the change. Obviously, "either of these expedients results in an increase in mill costs.

Accordingly, it is an object of this invention to provide means for effecting thetransfer of a webfrom one reel to another completely automatically.

It is a further object of this invention to provide means for binding first the edge portions of a web to a rotating reel'and progressively binding portions of the web extending toward the center thereof to the reel while a progressively diminishing central portion of the web continues to proceed beyond the reel.

It is a further object of this invention to provide means of the type stated which will operate without the necessity for special manipulation of any type. v

It is a further object of this invention to provide a winding reel'with means for securing a web thereto which becomes automatically operated upon initiation of rotation of said reel.

It is a further object of this invention to provide a winding reel with a loop of wire or other flexible elongated material secured at its opposite ends to the Opposite ends of the reel for the purpose of securing a web thereto.

It is a further object of this invention to provide in a machine having a winding reel of the type just described a control device for insuring reliable operation of said web-securing means.

It is a further object of this invention to progressively secure an increasing width of a moving web to a winding reel while a proportionately decreasing width of said web continues to be wound upon another winding reel.

It is a further object of the present invention to provide a mechanism in which there is a firstreel upon which a continuously moving web is being wound and a second reel uponwhich it is desired to transfer the-web, together with an automatically operated device for severing and seem"- ing said web to said second reel;

Other and further objects of this invention will become 'more" apparent upon a reading of the following specification in which is described a preferred, but obviously not necessarily the only, form of embodiment of the invention and by reference to the drawings forming a part of the specification.

In the drawings, wherein similar parts are identifled by similar characters of reference throughout the several views Fig. 1 is a side elevation of a winding and severing device embodying the present invention; I

Fig. 2 is a plan view of the device shown in Fi-g.' 1 looking in the direction indicated by the arrow II in Fig. 1, certain parts having been -m'oved from their'normal position for the-purposes of illustration;

Fig. 3-isa view similarto Fig. 2 illustrating certain steps in the operation of the mechanism;

Fig. 4 is a view similar to Fig. 2 illustrating the condition of a winding reel when the operation of the mechanism is complete;

Fig. 5 is a fragmentary view illustrating thestood that the mechanism thus far'described may comprise the last drying stage of a papermaking machine, in which event the drum I0 is a drier drum and the felt I l is a portion of the felt normally used for conducting the web through the drying stages. It will be further understood that the mechanism thus shown is purely illustrative and that the web l3 may be discharged from any suitable machine from which it is desirable to discharge a continuous web of paper, fabric and the like. Thus, for example, the web l3 may be discharged from a paper coating machine or paper finishing machine such as a calendar stack, or from a fabric weaving or treating machine.

From the guide roll It the web I3 is conducted over the upper peripheral portion of a driving drum I! which is driven for rotation in the direction of travel of the web and'preferably at or substantially at the speed of travel thereof. As shown in the drawings, the driving drum I I is rotating in a counter-clockwise direction. The web I 3 progresses across the drum and is wound upon a. reel l8 from which protrudes the ends of a shaft I!) which is rotatablysupported in a pair of bearings 20, 2| formed upon the upper ends .of arms 22 and 23, respectively, fixed for rotation with a shaft 24 rotatably mounted in bearings 25 secured to the base 26 of the winding device. As the web continues to wind upon the reel 18 it forms a roll of increasing diameter, and as the circumstances. When this diameter is reached dling a. continuous supply of web is that com In general the Pope reel is provided with a pair of side frames it is necessary to discontinue further winding upon the reel l8 and to make some other provision for the continued supply of web 18. The mechanism illustrated in Fig, 1 for hanmonly known as the Pope reel.

21, 28 which are pivoted upon suitable bearings 2!! and 30, respectively, supported upon the base 26 in a position eccentric to the drive shaft 8| for the driving drum 11. As shown in the drawings, the bearings 29 and 30 may be formed as a part of the pillow blocks 32 and 33 within which the drive shaft is rotatably received. These pillow blocks are rigidly secured to the base 26. The side frames 21 and 28 have formed thereon -open bearings 34 and 35, respectively, which are provided with elongated slots within which may be rotatably received the shaft of a paper winding reel. The proportions of the open bearings 34 and 35 are such that the shaft of an empty reel may be received therein when the side frames 21 and 28 are in the position illustrated in Fig. l.

The empty reel may be maintained out of contact with the periphery of the driving drum l1 unit may be lowered into contact therewith. When the web has been secured to this empty operation of winding a web upon a new'reel; and "paper reel'and winding thereon begins the dishown in full lines by suitable overhead crane mechanism indicated generally at 31a, as is well understood in the papermaking art; When the desired diameter hasbeen'built up upon the active reel l8 the empty reel 36 is lowered within the bearings 34 and 35 into peripheral contact with the web l3 as it progresses across the upper portion of the drum l1. This will result in rotation of the reel 36 and under normal operation of the Pope reel the web l3 must be severed, permitting the trailing edge thus formed to continue on to the reel l8 while the leading'edge thus formed must be conducted around the empty reel 36 to initiate winding thereon.

Whenthis hasbeen accomplished the filled reel I8 is swung away from .the driving drum by rotation of the shaft 24 by any suitable mechanism such as the hand wheel 38, and it is then removed from the bearings 2El, 2| for such disposal as may be desired. The bearings 26, 2| are then swung back into proximity with the periph-- ery of the driving drum l1 in such a position as to receive the shaft 31 of the new reel 36. In the meantime it will be appreciated that the web has continued to wind upon the reel 36 and that the diameter thereof is progressively increasing. It is desirable at this juncture to move the reel 36 from the bearings 34, 35 tethe bearings 20, 2!. To this end the side frames 21 and 28 have formed thereon gear segments 39, 40 which are concentric with the bearings 29, 36. The gear segments 39 and46 mesh with pinions, one of which is shown at 4| in Fig. 1, fixed upon a shaft 42. The shaft 42 is rotatably carried in suitable bearingaone of which is shown at 43 in Fig. 1 The shaft 42 also has fixed thereon a hand wheel 44 by which it may be rotated for the purpose of swinging the side frames 21, 28 about their .re-

spective bearings 29, 30.

Rotation of the hand wheel 44 in a clockwise direction will cause a swinging of the frames 21, 28 in a counterclockwise direction whereby to move the reel 36 in the direction of rotation of the'driving drum [1, while the web continues to wind thereupon. Inasmuch as the centers of the bearings 29 and 30 are eccentric to the drive shaft 3| of the drum' l1 this shifting movement of the reel 36 will tend to move the shaft 31 thereof out of the open bearings 34, 35. The position assumed by the bearings 26, 2| is so related to the path of the bearings 34, 35 and shaft 31 carried therein that the shaft 31 is discharged from the bearings 34, 35 into the bearings 26, 2|. Thus the reel 36 will thereafter be supported in the bearings 20, '2! and operations will proceed 'as above outlined in connection with subsequent empty reels which may be introduced into the bearings 34, 35.

The above description has reviewed in a brief manner the operation of the Pope re'eL'and such operation is old and well known. The present invention is particularly adapted for use in connection with the Pope reel, and it is for this reason that the above description has been made. 1 It will .be appreciated that any desirable variations may be made in the Pope reel mechanism without affecting the cooperation of the present invention therewith, and it will be further understood that the present invention is equally well adapted, in its present form or in such forms as may be within the scope of the appended claims, for cooperation with other forms of continuous reeling mechanism.

Referring now to Fig. 2, it will be observed that the reel 36 chosen for illustration in connection with the present invention may comprise a core portion 45 which may be made of any suitable material, as, for example, laminated paper, and end caps 46 and 41 which may be formed of metal. These end caps are secured in any suitable manner to the core portion 45 andare preferably keyed to the shaft 31. Each of the caps 46 and 41 has a depression 48 formed therein (see Fig. 5) within which is secured a stud or screw 49 in such position as to lie within the peripheral confines of the cap. It will be understood that the reel I8 is constructed similarly to the reel 36,

and it will be further understood that all reels driving drum l1, an elongated flexible member- 50, such asa wire, cord, twine or cable, is fastened to the stud 49 secured within the cap 41. For purposes of convenience the member 56 will be hereafter referred to as a wire. The wire 50 is carried downwardly from the reel 36 alongside the web l3 and beneath the web. It is then conducted across the machine and upwardly past the opposite edge of the web l3, and its other end is secured to the stud 49 located within the cap 46. There is thus formed a continuous loop of wire extending from end to end of the reel 36 and including within it the web 13.

So long as the reel 36 does not rotate the wire 50 will remain out of contact with the web l3, and it will not interfere with the continuous movement of the web therethrough as the same is wound upon the reel [8. When it becomes necessary to transfer the web from the reel iii to the reel 36 the reel 36 will'be lowered into peripheral contact with the upper face of the web l3, and the reel will immediately begin to rotate. When such rotation starts the wire 60 will be wound upon the reel 36, and since'the wire is in the form of a continuous loop, winding thereof will rapidly progress toward the center of the web. Thus the wire will progressively form helical turns around the reel until such time as the entire loop has been taken up. As this operation begins the wire will be brought into contact with the opposite edges of the web l3 and will cut into these edges. Inasmuch as the wire is progressing toward the center of the machine the portion of the web which is severed thereby will necessarily be encompassed within the turns of wire and will thereby be secured to the reel 36. After a -few turns the loop will be entirely taken up and the web will have been severed inwardly toward the center, the central portion thereof having been. decreasingly directed to the reel l8 and the outer portions thereof having been increasingly directed tothe reel 36.

As thus far described, the wire loop may ha g freely from the reel 36, and it may be so d through which the bolts 52 pass.

posed as to normally hang out of contact with the web. This arrangement is entirely capable of performing the objects of my invention, but it will be appreciated that the freely hanging wire may in some instances be objectionable. For example, the proximity of this freely hanging wire to a rapidly moving web may lead to inadvertent contact therebetween and damage to the web. Accordingly it has been found desirable to provide some form of means for holding the loop in a predetermined shape and insuring freedom from inadvertent contact with the web. It has also been found desirable to control the winding of the loop upon the reel in such a manner as to relatively evenly space the helical turns across the width of the reel. This latter provision leads to more reliable operation of the device. Ac-

other end of the block 55 extends below the pin 51 for a distance approximately equal to the remaining depth of the channel 54. When the block 55 is rotated into the position shown in full lines in Figs. 6 and 7 the axis of the stud 58 forms a substantial continuation of the arm 53. When the block 55 is rotated into the position shown in dot and dash lines 'in Figs. 6 and 7 the axis of the stud 58 extends substantially at right angles to the arm 53.

Inasmuch as the axis of, the pin 61 is transverse the channel 54 a pull exerted upon the cordingly, there is illustrated a form of mechanism for yieldingly holding the loop in a predeter- 'mined shape and for symmetrically guiding the loop during the winding thereof upon. the reel.

As shown in the drawings with particular reference to Fig. 2, the wire 50 is conducted beneath the web and around a pair of sheaves 52 carried by the'free ends of pivoted arms 53'and 54, respectively. At their lower ends the arms 53,

and 54 are hinged to a frame member 55, and they have fixed for rotation therewith a pair of wheels 55 and 51, respectively. The wheels 55 and 51 are interconnected by a crossed belt 55 which serves to force equal angular rotation in opposite directions upon the arms 53 and 54. A pair of springs 59 and 59 are respectively tensioned between the arms 53 and 54 and a stationary portion of the frame. The springs 59 and 50 tend to rotate the arms 53 and 54 away from oneanother and thus to separate the sheaves 52. Due to the interconnection of the arms through the belt 58' the sheaves 52 will be maintained substantially symmetrically on either side of the center of the machine. The loop of wire 55 is thus spread into a generally rectangular shape as illustrated in dot and dash lines in Fig. 2. Upon windingof the loop on the reel 35 the arms 53 and 54 will be drawn toward one another 4 against the tension of the springs 59 and 55 and the wire will thus be held under tension and guided symmetrically toward the center of the web I 3.

Suitable mechanism must be provided for releasing the loop in.order that it maybe per-.- mitted to complete its winding upon the reel 35. A preferred form of releasing. mechanism is illustrated in the drawings and is shown in detail in Figs. 6 and 7. In these figures the arm 53 and the release mechanism associated therewith are illustrated and it will be understood on the arm 54.

A U-shaped bracket 5| is secured by bolts 52 to the end of the arm 53 in such position that one leg of the U is brought into contact with the arm. The other leg of the U is laterally spaced from the arm by a spacing block 53 The bracket 5| and arm 53 thus define an open channel 54. The web of th bracket 5! extends over the end of the arm 3 and it has formed therein a pivoted block so. The block 551s pivoted upon a pin 51 passing through the bracket 5| and the end or the arm 53 in a directiontransversely of the channel 54. One end of the block 55 is threaded to receive the bearing-stud 58 upon which the sheave 52 is freely rotatable. The

' that an identical release mechanism is provided notch 55 of suitable dimensions to receive a sheave 52 crosswise of the arm 53 will be ineffective to rotate-the block 55 about the pin 51.

However, a pull substantially lengthwise of the arm 53 will be efiective to'rock the block 55 about its pin 51 and thus to move the sheave 52 from the position shown in dot and dash lines in Figs. 6 and 'z to the position shown in full lines therein. I

Referring now to Fig. 2, it will be observed that the sheaves 52 are arranged in the positions illustrated in dot and dash lines in Figs. 6 and '7. In these positions the wire 50 is guided around the sheaves and it will be appreciated that the pull thus exerted upon the sheaves will be ineffective to move the blocks 55 from their position. When the wire 50 is wound upon the reel 35 and the arms 53 and 54 progressively move through the position shown in full lines in Fig.

2 the pull of the wire gradually shifts from a direction transverse the arms to a directionapproaching the longitudinal. When the arms reach the positionshown in full lines in Fig. 3 the pull of the wire upon the sheaves has become substantially longitudinal, and the blocks 55 will be caused to rotate as shownin this figure.

Thus the sheaves 52 will be moved to a position The operation of the device will now be set forth. I

Referring to Fig. 1 it will be assumed that the empty reel 35 is suspended adjacent to but above the periphery of the driving drum I I and that the wire 50 has been secured to the studs 49 whereby to form a loop extending outside the edges of the web l3 and transversely beneath the p web over the sheaves 52. The wire 50 will thus be arranged as shown in dot and dash lines in Fig. 2. When it is desired to transfer the web from the reel ii to the reel 35 it is only necessari? to lower the reel 35 into peripheral contact with the upper surface of the moving web I3. Frictional engagement will immediately cause rotation of the reel 35 accompanied by winding -of the wire 50 th'erearound. Winding of the wire will serve to shortenthe loop and thus to swin the arms 53 and 54 toward one another. Very shortly after winding commences the wire will be brought into engagement with the opposite edges of the web l3 and will cut into the web along a line rather closely coinciding with the line of contact between the reel 35- and the drum l1. Cutting of the web is actually eifected by the action of the wire- 50 in binding awportion of the web to the reel 35 and thus the line of severance will lie on the side of the wire toward nip between the the center of the machine. This is illustrated Fig. 2 wherein a tab l3a has been cut from each arms 53 and 54. The remaining portion of the wire loop will be rapidly wound upon the reel 36 and transfer will be complete.

In each of Figs. 2 and 3 the reel l8 has been moved from its actual position in order that the progress of the web thereto might be illustrated. It will be observed that the trailing end of the web tapers to a relatively narrow width and that the central portion of the web is finally severed substantially straight across, as illustrated at l3b in Fi 4. I

In Fig. there is a further detailed showing of the manner in which the tabs l3a are secured to the reel 36. In this view' the overlying portions of the tab have been broken away in order to illustrate the arrangement of the line ofseverance on the side of the wire 50 toward the center of the machine. The wire 50-is also illustrated as extending from its control mechanism to the it proceeds to wind helically about the reel 36. In this view it is thus entirely. clear how the wire serves to sever the web and to bind it to the reel 36.
