This invention relates to a winding apparatus, 1 and more particularly to a non-stop automatic transfer winding apparatus. The present application is filed in place of my abandoned application Serial No. 470;987. An object of the invention is to provide a mechanism for continuously winding "a web of paper on a plurality of successive cores in a completelyautomatic operation. Another object ofz-the invention is to provide; apparatus for winding a'web on a core or mandrel 'and automatically severing the web and transferring the'lea'ding end thereof to another fcore or mandrel without interrupting-the winding operation. Still another object is to provide a single machine, apparatus for slittingand "perforating a web of paperand for automatically 'severing the web atVpre-determined intervals so that the web may be continuously wound on suc- --cessive cores. Another object of the invention is to provide means for automatically severing a paper web "which is being woundon a mandreland for urg- 'ing the leading end of the severed web against "anothermandrel. Stillanother object isto provide mechanism for continuously moving a plurality-of mandrels-and for synchronizing with the movement ofthemandrels; the severance of the paper web and the bringing of the leading end of the severed web into engagement with a man-- drel. Other features and-advantages will appear from the following specification and'drawings, in Which: view of the apparatus of the invention; Fig. 2 ;is'- a similar fragmentary transverse sectional view "of thefapparatus showing the severing of the "paper web while it is being wound upon a mandrel'and the application of the leading end of the web to anothermandrel; Fig. 3, an-elevational view; Fig; 4, an end elevational view, the view 'being of the end opposite that shown in Fig. 3; and Fig. 5, a broken plan view. Inthe embodiment of the invention described herein and as shown moreclearly inFigs. 1 and 2, apaper web Wis-passed between a drive roll H and a bed roll 12. In passing about the bed "roll I2, the web is-brought intoadjacent relation with a perforating roll -l3 andasplitting T011 [4 and then passes between the'bed roll '12 and another drive roll l5. From the bed roll'jlZ, the paper-web passes to andis wound upon one wofthe-cores l6, l'l, lB- and lflmouhtedrespec- 1tively on the mandrels :20, 21,22 and '23. The ap- I spaced portions of the web. 1 inthedirection shown by the arrows'injF mounted on a mov'able turret 32, whichin ,turnQis Fig. 1 is a fragmentary transverse j-sectional i annular projecting portion of thejs'litt ll paratus .is designed (to provide .a .continuousylinding operationin whichthe Web i'siautbmatic" 11y transferred from one mandrel to another without interrupting theoperation. The drive roll H on the shaft 241s positively driven and is arranged with the bed roll III-to frictionally engage the web lfltherebetween. The bed roll I2 is rotatableron the shaft 25. The bedroll I2 isequipped withlongitudinal recesses 26- ,which are" adapted. to receive meterforating knives 2i onthiroll' I13.

Preferably, the bed roll l2,.is.equ, pped with an annular groove .or recess 30' forrebeivi the The roll"l5 on the shaft"3l maybe i'positw l i na may be arranged with the bed mu 1: to frictionally engage the .web I 0 ftherebetween. The positively driven rolls I5 and II are rotated The mandrels' 20, 2], .22 and"'23nare,rotata rotatably supported by the shaft 33. The turret 32 may bearranged for rotation on thefshajfti fl soas to move the mandrels carriedjtherebyifin the counter-clockwise v direction indicated, by the arrowin" Fig. 1. Any suitable mechanism .may be used for rotating the turret. Preferably; the turret is rotated at such a speedthatan'iandrel -22 in web. winding position as "shown in"Fig. l, may be moved tothe position 'of the mandrelifl, in Fig. .1, in the time required to windy'the web to its full extenton the core on'the; mandrel. Thus,the core on the mandrelreceives,.the web when the mandrel reaches "theiw'eb winding posi-- tion of the mandrel 22 Q shown Figl 1, ,ar'idf gby the time the .web has been completely wound on the core onthe mandrel, the mandrel has reached the position beyond web,winding position-gin which themandrel'l23. is shown inFigi 1'. An arm 34, which. mayif desiredbemounted on the sh'a'ft 25, carries al-knifebladei35iand. a nozzle 36. The arm 34 is arranged to movetoward and away fromthe web lfl atjtheportionthereof between the mandrelsi22and23fi The knifebl ade .35 may be of. any I suitable or c'onventional -type 3 adapted to sever the web when brought into engagement therewith. The nozzle 36 is adapted to receive a conduit for delivering fluid under pressure to the nozzle 36. Preferably, a mixture of compressed air and water is passed into the nozzle and emitted therefrom under pressure. The arm 34 may be actuated by any suitable means so as to bring the knife blade 35 into engagement with the web l8 at the portion thereof between the mandrels 22 and 23 to sever the web |8 when the core H! on the mandrel 23 has been fully wound with the web. Preferably, the actuating means for the arm 34 is automatically operable and is synchronized with the movement of the turret 32 so that the arm 34 is moved forwardly when the mandrels reach the position shown in Fig. 1. The fluid, which is supplied to the nozzle 36. is controlled by a suitable valve mechanism so that fluid under pressure is ejected from the nozzle 36 immediately after the web l8 has been severed by the action of the knife 35. The nozzle 36 thus serves to bring the fluid into engagement with one side of the leading end of the severed web, and thus causes the leading end of the severed web to be brought into engagement with the core |8 of the mandrel 22, as seen in Fig. 2. Fluid is ejected under pressure from the nozzle 36 only immediately after the severance of the web l0, the valve mechanism being synchronized so as to operate only at the periodic intervals of the actuation of the arm 34. When the web ID has been fully wound on the core IS on the mandrel 23 and the mandrel 23 reaches the position shown in Fig. 1, the arm 34 is automatically actuated to bring the knife 35 into engagement with the web ID. The knife 35 severs the web at the portion thereof between the mandrels 22 and 23. Immediately upon the severance of the web H] by the knife 35, the nozzle 36 ejects a stream of fluid under pressure (preferably a mixture of compressed air and water) to force the leading end of the severed web into engagement with the mandrel 22. The mandrel 22, of course, is in engagement with or immediately adjacent the side of the web opposite that which is adjacent the knife blade 35 and nozzle 36. A complete machine, which supplies the power for the various operations shown in Figs. 1 and 2, is set out more fully in Figs. 3, 4 and 5. In the latter figures, A designates a base or frame for supporting the operating mechanism hereinafter described. A bracket A provides a support for the roll 40 which carries the paper stock H). A main drive shaft 25 is mounted in the frame A and is equipped with a drive wheel 4| to which power may be supplied by belt or by gear mechanism or by any suitable means. The drive shaft 25 carries the bed roll l2, and at the opposite end of the casing is equipped with a gear 42 meshing with the gear 43 on shaft 24, the gear 44 on shaft 26, the gear 45 on shaft 29, and, as shown more clearly in Fig. 4, the pinion 46 on shaft 3|. Shaft 3| carries also the pulley drive member 41. Suitable pulley and belt means are provided for driving the mandrels 20, 2|, 22 and 23 on the turret 32. Such belt mechanism is shown more clearly in Fig. 3. A pulley 48 is mounted upon a standard 49 carried by casing A and receives a belt 50 driven by pulley 41. Pulley 48 is fixed to a rotatable shaft and shaft 5| carries another pulley 52. A belt 53 connectsthe pulley 52, a pulley 54 carried by shaft 3|, and an idler pulley 55 carried by shaft 56. Shaft 56 is mounted upon an arm 51 pivotally carried upon casing A by shaft 58 and is urged outwardly against belt 53 by an integrally weighted arm 58. The belt 53 is adapted to engage a drum 68 carried by each of the mandrels 20, 2|, 22 and 23 and, as shown best in Fig. 3, the belt normally engages two of the drums at one time. By this means, the rotation of each of the separate mandrels, when in contact with the paper web I0, is rotated independently of the turret shaft 33. Power is supplied to the turret shaft 33 by the following means: The shaft 25 is provided with a worm 6|, as indicated in Fig. 3, and the worm 6| meshes with a worm gear 62 carried by a cross shaft 63. The ends of the cross shaft 63 are provided with bevel gears 64 and 65. Bevel gear 64 meshes with gear 65 carried by shaft 66. Shaft 66 extends through the frame members A and at its opposite end carries gear 61. Gear 61 meshes with an intermediate gear 68 carried upon shaft 69 and, in turn, gear 68 meshes with the upper gear 10 carried upon shaft 1|. Shaft 1| carries a pinion 12 which meshes with the large gear 13 carried by turret shaft 33. Power is supplied to the knife 35 and to the fluid discharge member 26 by the following means: The bevel gear 65 carried by the cross shaft 63 meshes with bevel gear 14 mounted on shaft 15. Shaft 15 carries a wheel 16 to which an eccentric member 11 is pivotally mounted by means of pin 18. The eccentrically-mounted member 11 carries a rod 18 which pivotally engages the member 34 carrying knife 35, as shown best in Fig. 3. Any suitable means for automatically supplying fluid to the nozzle mechanism 26 may be employed. In the illustration given, the nozzles 26 are connected by a manifold pipe secured to the knife arm 34. Communicating with the pipe 88 is a flexible hose 8| which is supported by bracket 82 on casing A. A pipe 83 connects the hose 8| with a valve device 84, as shown more clearly in Fig. 3. The valve device 84 is provided with a plunger 85 adapted to be engaged by a cam 86 carried by the wheel 16. The cam 86 controls the operation of the plunger 85 to release fluid in timed relationship with the action of the knife when cutting the paper web I, as heretofore described. An idler roller 81 is carried by shaft 88 and provides a support for the paper web I0. In operation, the web It! is drawn between the drive roll H and the bed roll l2 and is passed along the perforating roll l3 and slitting roll l4 and then between the drive roll l5 and bed roll |2. In passing the perforating roll l3 and slitting roll M, the web is perforated and slit. From the drive roll |5, the web continues to pass along the bed roll |2 to the core l9 on the mandrel 23. As the turret 32 is rotated and the mandrels are moved to the web winding position of mandrel 22 and then beyond this position to the position of mandrel 23, the arm 34 is actuated at intervals so as to sever the web I0 at the portion thereof between the mandrels 22 and 23. The severing of the web is immediately followed by the application of fluid pressure to the side of the leading end of the web which is opposite the side adjacent the mandrel 22. In this manner, the web is brought into engagement with the mandrel 22 and is wound thereon. The continued operation of the device brings the mandrels 20 and 2| into web winding position and then beyond this position. The web is continuously and automatically wound upon the cores on successive mandrels, the transfer of the web from one mandrel to another being completely automatic. Although the invention has been described in connection with a particular embodiment, it will be apparent that modifications and changes may be made without departing from the spirit and scope of the invention.
