Application led March 12, 1,923. Serial No. 624,357.

This invention relates to web-windingmachines. More particularly, it relates to a machine in which a web of paper', cloth or other lexible material is unwound from a parent roll, slit into units of the desired width, wound upon tubes or cores fed to the machine, perforated, wrapped, glued and discharged. There are no machines at present in use for performing all of these operalo tions. According 'to the best practice prior to my invention, the operator places the tubes or cores about which 'the material is to be wound, upon a. spindle, places the spindle in the-machine, wra s by hand sevl5 eral turns of the material gom the parent roll. about the core and starts the machine, which then Winds and slits by motive power, When the desired quantity has been Wound, the operator stops the machine, breaks the 2o paper along the 'width ot .the web, glues the end of the rolls, removes the spindleA from the machine and lWraps the rolls by hand. This operation is repeated for each set of rolls. lt is broadly the object of the present 2t invention to provide' a machine, which shall perform all 'of these loperations `without the intervention ot the operator; and in which the entire sequence from the feeding of the cores to the discharging of the Wound, 3o Wrapped and glued rolls shall be automatic and continuous as long as any material re mains on the parent roll.

l have attained this object by providing three sets of rollers, which are automaticall rotated in predetermined sequential combinations. @ne set, the winding and Wrapping rollers hold and rotate the core and Wind the web ot material about it, slitting ,the material into sheets of appropriate 4o Widths at the same time and cutting the core into unit lengths. A. second set, the feeding rollers, feed the material to the vcore from the parent roll and cooperate, with a perforator vto perforate or score it transversely at intervals or at the end of i the Winding only. lWhen the desired length of material has been wound about the core, 'the feeding rollers stop, while the winding rollers continue to rotate. This tears the material along a perforation and separates the wound roll from the web. 'Thereupon a third set of rollers. the wrapper rollers,

y feed a wrapper to the Winding rollers cooperate with a perforator to perforate or score it after a predetermined length has ation is initiated.

lfrom a parent roll and Windin vbeen fed. and automatically apply glue'to it.

"continue to rotate, thus tearing the Wra per along the perforation and detaching it rom the Wrapper web. The Winding rollers then continue to rotate. in winding positionA long enough to tighten the Wrapper about the roll and ensure the adhesion of the glue. Thereupon the Winding rollers separate' to dischargethe Wound and wrapped rolls, and a new'core is fed into place. The operation is then repeated.

ln carrying out this sequence. of operations automatically, I have found it necessary in starting the Winding toprovide means for guiding the advancing end 'of the web about the core. This l do in accordance with the 'present invention by means of properly directed and timed air Jets.

To operate these three sets of rollers in their sequential relations, l have designed three gear trains, each controlling the rotation of 'a given set of'rollers. These gear trains are thrown into-and out of connection with a constant source of power in properly timed relation, bymeans ol a'constantly rotating cam drum. `This drumA is also designed to control the core feed-and roll discharge mechanisnn the perforator and the air Jets, which guide` the oncomingweb about the core 'when each Winding opel` ln order that the invention may be morev clearly understood, l shall now describe the" construction and operation of a preferred embodiment of it, which isillustrated in the accompanying drawings. This machine was designed primarily for unwinding paper it about a series of individual cores, and t e invention will 'be described in connection'with this machine, although itis. of course, obvious that the principles involved are not so `t0n limited.- ln these drawings, Fig. 1 is a side elevation of a sheet winding machine, built in accordance with the present invention with part of the gear housing removed to show the ythree gear trains and the cam 105 drum`; ig. 2'is a' vertical transverse section ofthe machine taken along line 2f2 of Fig. 1; Fig. 3 is' a horizontal section taken along line 3-'3 of Figs. 2 and 4; Fig. 4 is an enlarged vertical, transverse section taken llo 1o wrapped core alo line 4-4 of Fig. 3 and shdwing in particular the three sets of rollers 'and' the core feeding mechanism, (in this view the core is shown'in the'act of being wound);

As shown 1. As shown inv Fi 1 the rollers areheld within the left han part of the frame, and

the operating mechanism, the gear trains, cams, etc., are housed within the casing 2 at the right hand :part of the machine. I

Y shall first describe the o eration of the rollers and the core feed an --dscharge mechanisms, and shall then'turn to a consideration of the'construction and operation of the variousgear trains, which actuate. these .partaf' In describin the rollers and the core feed mechanism, I all refer particularly to Figs. 4, 5 and 6. In these figures, 3.represents the parent roll, which -is suitably mounted .for rotation wlthin the frame 1. The parent wrapper rollis indicated at 4, and is suitably mounted at the top of the mac e.

rollers, tbe windin andwrapping rollers, and the .wrapper eed or wrgiper rollers. The f rollers are indicat y 5, 6, and 7;thewin grollersby8,9and10andthe ' wrapper rollers b 11, 12 and 13. The pa r web is perfora forating hxife 22 mounted upon a rotati shaft 23, and cooperat' with a longitudinal'groove 24 in the f ing roller 6. The wrapper is similarly perforated or cut bfyt means of a knife 25 rotating upon a sha 26 and cooperating with a groove 27 in the ycores l are fed intonwinding position between e windmg ro ers from a magazine 15; this. feeding being governed by star wheels 16. During the initiation 'of the winding action, the oncomi web is guided about the core and between e core and the 7, and/showing some-- 4 in the drawings,'the machine is supported upon'and enclosed'within a frame There are three sets of'rolllers-the feeding'.

plurality of annularslitting knives 19, which fit withm appropriate grooves 20 in feeding roller 7 (see act first to sever the cardboard core, then ig. 1 1). These slitting knives to slit the oncoming paper web and finally to l slit the wrapper.- Y

This wrapper, as it is fed to the wound roll, is coated with strips of glue by contactingwith a series of gluing discs 28 which dip within a glue reservoir or trough 29 as the rotate.. In order to prevent this glue frombecomingsmea'red over the face of the .wrapper rollers or Vthe winding 1 roller 10 with 'which the 'glued face of t wrapper comes in contact, .1 rovide these rollers 12 and 10 with suita ly placed grooves 31 and 32. y

Dischaii'ge of the wound and wrapped rolls is e ected byv a downward movement, at the appropriate time, of the lowest winding roller 9. This removes the support from the roll andpermits it to make its exit from the machine under theiniluence of gravity.

In order to make clear the o ration oi h malline l:sthdeeribed thus dnallmsll". shall oow ug e itng mapping, gluing aeritdmscharging of. one, roll. Fig. 5 the relation of the parts just after the star wheels 16 have turnedl, of a revolution to feed a new. core between the winding roller. The roller 9 has returned part way from discharging position, -just enough to permit the new core to roll into place but not enough to force it into windin position against the other two winding ro ers. As the new core drops/'between rollers 7 and 9 it falls against the upper ends of the pipes 17 which serve as Y stops and hold it temporarily until the roller 9 returns to winding position. This return movement of the roller 9 is now immediately` completed 'so that the new core is held snugliy in winding position between the three win ing rollers (as shown in Fig. 4). simuitaneously the feeding and winding rollers begin to rotate, cooperating to feed the web 33 from the parent roll 3 around the feeding rollers and to the core. Rollers 7 Aand 8 are spaced slightly apart so tlht the paper is not pinched between them. `The reason for Athis will be obvious when I describe the severing of the wound roll from the web. At the same time, jets of air iuing from the pipes 17 and 18 guide the advancing end of the -web about vthe core and between the core and the winding rollers. This air continues to blow until theJweb has made one complete Y turn about the com, meanwhile the slitting foration for each revolution of the'feedin roller 6. If, however, the paper woun upon the core is to be one continuous sheet,

'the web.

.' chine through pu'lley35.

the shaft 23 does not rotate until the time comes to sever the paper on the core from When this time comes, the feeding rollers 5, 6 and 7 stopl and the winding rollers 8, 9 and 10 continue to rotate. At this time a perforation extends across the web between the core and rollers7, and 8, so that con-l tinued rotation of the core by the winding rollers, exerting a tension upon the web,

tears it along this perforation. At the same time, the wrapper rollers 11, 12 and 13 begin to rotate, feeding the wrapper web from its roller down between rollers 7 and 10 to the wound core. These rollers are spaced slightly apart so that the counter-rotation of roller 10 does not interfere with the feeding of the Wrapper. rlhis arrangement also lessens the likelihood of smearing roller 10 with glue. As the wrapper web 34 contacts with thelgluing discs 28, it causes them to rotate and thus apply strips of glue to the lcontacting face of the wrapper. The wrapper is thus fed to the wound roll and as it adheres to it the u/seof air or other means for causing it to follow the rolll is unnecessary. Simultaneously with the rotation of the wrapper rollers, the shaft 26 rotates and the knife 25 perforates the wrapper web, thus marking od' a wrapper. of the desired length.

When the wrapper has been completely Wrapped about the roll, the lwrapper rollers stop and thewinding rollers continue to rotate long enough to sever the wrapper along the perforation from its web and press it tightly about the roll. At this point,

described above. In this description, par-- ticular reference will be made to Figs. 1, 2, 3, 7, 8 and 9. Power -is appliedto the mariven in any desired manner from any prime mover. This pulley 35 is mounted upon Ia, shaft 36 ]ournaled in the casing 2 ofthe machine and iscoanial with a bevel pinion 37 likewise fixedto the shaft 36, this inion 37 meshin with 4a second bevel pinion -3 which rives a worm39. This worm drives a large worm wheel"40, to which is fixed `a cam drum 41. The shaft 36 extends to the left, as shown in Figs. 1, 8 'and 9, and is journaled" at its inner end in a sleeve 42,

-' lower 62,l t

which is integral with and forms the shaft of feeding roller 7.

Fixed upon this sleeve and coaxial with the shaft 36 is a pinion 43, which in turn4 meshes witha gear- 44, which gear meshes with a second inion 45. The gear 44.is fixed to thepsha t of the -feedino roller 6 and the pinion 45 to the-shaft oi=` the feeding roller 5. Thus the pinions 43, 44 and 45 constitute the gear train, which operates the feeding rollers, and in order that these rollers be rotated, it is only necessary that the pinion 43 beoperatively connected to the constantly rotating shaft 36.

Loosely journaled upon the shaft 36 adjacent the -bevel pinion 37,'is a pinion 46 which meshes with the pinion 47, which inA turn meshes with inion 48, and that again with pinion 49. hese pinions 47, 48 and' 49 are keyed to the shafts of the wrapper rollers 1l, 12 and 13 respectively, and hence with the pinion 46 constitute the gear train which actuates these rollers.

Loosely journaled upon the shaft 36 and intermediate the two inions 43 and 46, is a double-faced clutch pinion 51, mounted for longitudinal movement upon-the shaft 36, and being wide enough to remain in mesh with the adjacent' gears of its train in every position which it may be in upon the shaft 36. Meshing with this clutch pinion directly to the right, as shown inl Fig. 7 is a pinion 52 and directly vloelo'vv it is a pinion 53. Meshing with the pinion 53 in an idler gear 54 which in turn meshes with a pinion 55, mounted upon an Varm 56, pivoted about the axis of the idler 54. The other end of this arm 5 6 terminates in a cam follower 57. 'lhe arm' 56 is normally held in the position shown in Fig. 7 b means of a tension coil spring 50, but un er the action of the cani drum cooperating with the earn follower 5i' (the loperation of which will be described later). This arm 56 may he swung to lowerV the position ofpinion 55. The pinions 52, 53 and 55 with 'the clutch pinion 5l constitute the gear train which actuates the winding-rollers, as will beevident from a comparison of Figs. 4 and 7.

Meshing with the gear 44 is a gear 58, loosely journaled upon the shaft 23. rllhis gear 58 can be thrown intooperativerela. tion with the shaft 23 hy means of a clutch 59, so that this shaft is caused to rotate with the feeding roller' 6 to perforate the web. The clutch 59 is operated by means of' an arm 60 pivoted upon a bracket 61 extending from the inner wall of the casing 2y and terminating 4at its lower. end in a cam fole operation of which will bedescribed later.

Meshing 'with 'pinion 48 of the wrapper' ing knife 25 rota tes in synchronisln with thev lili wrapper roller 12 and peri'orates` orl cuts a end terminates in a cam follower 66, which -is actuated in a manner to be presently described.

The shaft 36 is provided adjacent pinion 43 with upstanding keys 67 designed t'o cooperate with the clutch pinion 51 to key the latter to the shaft. Similar keys 68 are situated adjacent' the pinion 46, an'd are likewise designed to vcooperate with the pin-f` ion 51, for the same purpose. Both pinions 43 and 46 are provided with clutch faces 69,

ldesigned to. cooperate in turn with clutch' faces 70, on the pinion 51, so that the pinions 43 and 51 may rotate in unison at one time and the pinions 46 and 51 rotate in unison at another'time.

IThe star wheels 16 which permit the feeding of the new core into winding position are rotated step by step by means of a sixtoothed ear 72.

The air is admitted to pipes 17 and 18 from a main73 by means of a valve 74.

Arm 56 car ing geary 55, clutch arms 60 and 64, gear'w eel 72 and air valve 74, are all operated in their proper sequentialA relations by means of various cams situated upon the cam drum 41, which is constantly rotated through bevel pinions 37 and 38, worm 39 and worm wheel 40. The o ration of the en tire machine can be best escribed at the same time that the arrangement of the cams upon the cam drum is-described. As shown in Figs. 1, 8 and 9, the pinion 51 is in neutral position so that none of the gear trains is in motion. This is the situation while a wound and wrap d roll is being discharged from the machine, asV shown in Fig. 6. 'Immediately thisdischarg'e has taken place, the winding roller 9 returns to theV shown in Fig. 5, when a new core is opped -into place. This results from'a` turning of star wheels 16 to 1A; of a turn, which turning is effected by means of pin 75 on the inner face of the'drum contacting with the gear wheel 72. The winding roller 9.now forces the new core into winding position.

. At this momentcam 76 contacts with roller 77 of the valve 74, and rmits the discharge of air ,-throu'gh pipes 17 and `18. At the same time'. a cam 78 contacting with cam follower 66 of clutch arm 64 throws the clutch pinion 51 hard over to the left where its left hand clutch face engages the clutch osition is under the winding rollers continue and the wrapper rollers are put into motion. Thereupon the glued wrapper is fed'about the wound roll and perforated at the same time. When the predetermined length of ,wrapper -has been wound about the roll, a cam 81 contacts with cam follower 66, and throws the clutch. pinion 51 out of engagement with the clutch face 69 of pinion 46, but still in .contact with key 68, so that in this position the winding rollers alone rotate. winding rollers after the wrapper rollers have stopped, severs thel wrapper along the perforation and completesthe wrapping action. At this point, cam 82 contacts with *cam follower 57 on arm 56 and swings the piniony 55 and its winding 'roller 9 downwardly, into the position of 56, whereupon the wound and wrapped roll is discharged. After passing the peak of cam- 82, follower 57 drops under the action of its spring YtoY the lower portion of the Thus the roller 9 returns,`not to complete lwinding position but to the position shown in Fig. 5. Thereupon the pin 75 contacting with the gear 72 causes a new core to be fed -into winding position between the winding rollers. At this point, the cam follower 57 drops completely fromv the cam- 82, and under the influence of spring 50, the roller 9 is-forced upwardly to hold theqcore snugly between the three rollers. As the winding continues'and the diameter of the wound roll increases, vthe roller 9 is grad- This continued rotation of the ioo" ually forced downward, the arm 56 swinging slightly about its axis, but always urgedinto uppermost position by means ofthe spring 50. By means o'f this construction rolls of various diameters can be wound, and the roll pressure throughout the winding operation.

The machine as described is d ed to makeV one perforation for each complete wound rocllll and it undeisxl that some meanssu asaspr -not wn,are rovided for returningmie clutcirarm 6g to neutral position to disengage the clutch 59. Should itbe desired tov perforate at more frequent intervals and thus produce a i forated roll, the clutch 59 need onlylie permanentlyheld in clutching position throughout the entireoperation.

By means of my invention, lam able to -Wind, slit, wrap, glue, discharge the woundl rolls ^and feed new cores into wind-ing position, all automatically and continuouslylas long as any paper remains on the parent rolls. It is, of course, obvious that the wrapper rollers and their associated geartrains can be eliminated if it is not desired to Wrap the wound rolls. ln such an event, it would he possible to redesign the cam drum so that the clutch pinions 51 vneed never be shifted to the eXtreme right hand pos'tion as shown in Figs. 1 andS. The feeding rollers can be thrown out -of operation and the winding rollers continued in operation by lsimply sliding clutch pinion 5l to disengage it from pinion 43, but not far enough to disengage it from keys 67.

The' accompanying dra-wings showf the einbodiment of the invention, which is now deemed preferable, but it will be understood.

that various changes and substitutions of equivalents can be `made without departing from the spirit of the invention` as set forth in the claims-forming part of this application;
