ES?ANOLA, ONTARIO, CANADA AUTOMATIC WRAPPING-MACHINE Application and December is, was. Serial m. 154,507.

This invention relates to wrapping machines for c lindrical rolls and more particularly to mac ines adapted to wra news print and other rolls of considerab e size and weight and our object is to devise a machine for wrapping rolls of difierent dimensions equally well and which will fold the wrapper ends more neatly than is now possible by manual methods.

We attain our objects by providing a machine having side frames movable, on idewa s, towards or away from one anot er to adgust the machine for news print rolls of various lengths. Between the s de frames of the machine at one end thereof is located a transverse guide on which acarrlage is mounted. Behind the carriage are gournalled a pair of carrier rollers which carry and rotate the roll during the wrapping thereof. The paper roll is carried by a conveyor from a aper machine to the carriage and is aimed,

side frames, while it is passinover the carria e to the carrier rollers. T ese centering devices engage the ends of the roll and, 1f the latter is out of alinement, they will ush the roll and thus the carriage in either irectlon transversely of the machine toaccurately aline the roll. I

The mode of wrap ing the rpll is as follows: Firstly, an insi e header 1s applied to and held against each end of the roll second- 1y, a body wrapper is ssetted and wound round the roll between t e latter and the carrier rollers; thirdly, the overhanging ends of the'wrapper are folded in to cover the inside header and the tail end of the body wrapper is provided with glue; fourthly, band wra ers are wra ed round the bod wrapper d d lued the gto, these bands being also gussetted and folded in over the already folded-in ends of the body wrapper; and fifthly, outside headers are glued to the folded-in ends of the band wrappers.

As the roll passes over the carriage it de-' resses a rod which controls the operation of od wrap or feeding mechamsni and inside hea er fee ing mechanisms. The latter feed inside headers from magazines carried on the side frames to inclined header plates y means of centering devices relative to the.

which are swin ably mounted above the carrier rollers. he header lates carry the folding mechanisms for folding in the gussetted ends of the wra pers and are automa: tically swung in towar s the adjacent ends of the news print roll to hold the inner. headers n contact therewith and to hold the foldedm ends from spreading outward! When a predetermmed lengt of body wrapper is unwound from a bod wrapper suppl roll the later is automatica I stopped and t e body wrap er is cut ofi', g us is apphed to its tail en and feeding and gusset cuttmg mechanisms for the band wrappers are started. These bands are gummed in any suitable manner so that the portions of the bands wrapped round the b0 y wrapper are lued thereto. When a predetermined ength of each band wrapper has been fed from band wrapper su ply rolls the latter are automatically stop e and .the band wrappers are cut ofi. then dropped to permit the wrapped roll to run down a -runway leading to a conveyer located betwen the rear side frames of the machine. The stopping mechanism for the band wrappers also causes the outside header feeding mechanism to be started. On the rear side frames are carried the outside header magazines, gluing means, and endless belts. The headers are glued to the foldedin ends of the band wrappers and the endless belts appl pressure to the headers while they are rying. The wrapped roll as it leaves the drop roller causes the return of the header plates to their inclined positions. The roll while passing over the runway is automatically centered relative to the outside header applying means.

he carrier running between the endless belts conveys the wrapped roll to a scale where it is weighed and suitably stamped to show its weight, etc., according to standard practice. From this point it may be carried y another conveyor to a point for shipment.-

The constructlons are hereinafter more fully described and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of one end of our machine;

The news print rolls are brought to the machine by a conveyor 2 which rolls on to a sliglhtly inclined carriage 3, see

his carriage is mounted by means of anti-friction rollers on transverse guides 4 so that the carria e will readily and easily slide transversely of the machine when it is carryin a roll. The guides 4 are carried on a stationary frame 4 located between the'opposite side members 1. .On the frame is pivoteda weighted pendulum 5 having a in and slot connection with the carriage.

e pendulum is adapted to position the carria e in alinement with the longitudinal center ine of the machine.

' Roll al z'm'ng mchom'sm To aline the news print rolls while they are passing over the carriage we rovidecentering devices 6 carr ed by the orward side frames 1 located at opposite sides of the machine, see Figs. 1, 5 and 6. Thesecenterin devices include acranks pivoted at Between the bell cranks of each pair are ournalled two anti-friction rollers 6' and 6 which are spaced apart at'an an 1e of substantially 90. Normally the ro ers 6 are held by means of a weight or spring 9-in engagement with stops 10 which, when the bell passes the.

plurality of pairs of/bel 7 on converging bars 8..

cranizs are rocked on their pivots 7, are also ada ted to be engaged b tails 6' formed on the ell cranks. The r 1 R as it passes between the centering devices on the opposite 5 sides of the machine is adapted to engage the rollers 6 at least, of the devices located ad acent the mner ends of the converging bars 8 and rock the bell cranks and thus move the rollers 6 of these inner sets. The rollers 6* w are moved outwardly and the rollers 6 inwardly to engage the ends of the roll. If the roll is not in alinement, the inward movement of one of the rollers 6 will push it, and thus the carriage 3, transversely of the ma g chine and thus aline the roll. Should the roll R be so far out of alinement that it will engage the roller 6 of one of the centerin devices at the outer ends of the converging are, as shown in Fig. 6, the roll and carriage will be transversel shifted to engage the rollers 6* seriatim. he converging are are adjustably carried in an suitable manner on the side frames 1 so t at their angle of inclination to the center line of the machine may be varied.

Projecting slightly above the upper surface of the carriage 3 (see Fig. l) is an anti-friction roller 11 carried on a trip arm 11 which is guided in the frame 4 and which is adapt- 2d ed to be depressed, for a urpose hereinafter described, by the roll as it rolls over the inclined carriage towards the carrier rollers a and a which are journalled on standards 12. The letter are located between and secured to the guidewa s l at the forward end of the machine and t us do not interfere with the transverse movement of the side frames 1. The forward carrier roller a is constantly driven and is provided with a sprocket meshed with a chain a which is carried round idler sprockets a The rear carrier roller a is journalled in bearin slidably mounted in vertical guideways a ormed in the standards 12. These bearings are carried on saddles a provided with anti-friction rollers resting on the peripheries of cams a. The roller a is provided with a sprocket adapted, when the roller is in its normal or raised osition, to mesh with the chain a. The rol R is carried on the rollers a and a durin the application of the inside headers 2' an the wrappers and is rotated by frictional contact with the carrier rollers.

I aside header feed sides of the machine in inclined magazmes c" suitably secured between the adjacent side frames 1. The magazines are'provided with tracks on which followers 73' run, see Fi 3 v and 1. The headers for opposite ends 0 the roll R are simultaneously fed b means of feed rollers 2', each adapted to fee one header from its magazine on to a header plate 6 during one revolution of the feed roller. To

eliminate the possibility of more than one header bem engaged by the feed roller dur- 1n 1ts revo ution, the circumference of the ro .er 1s shghtl reater than the diameter of the header an t e roller is provided with a pro]ect1on i adapted to enga e a hinged flap on the magazine to push the eaders and the follower up the inclined tracks and thus hold the stack of headers in spaced relation to the feed roller. When the roller is again rotated the pro ect1on moves away from the headers and permits the follower c to present a fresh header to the feed roller.

The feed rollers are secured to shafts 17 arranged longitudinally of the machine and ournalled on the side frames 1" at opposite sides of the machine. The forward end of each of these shafts has a bevel gear secured thereto and these ears mesh with bevel gears 71. which are feather ke ed on a transverse shaft 5* which is journa led on the forward ends of the op osite side frames 1. The gears i are provi ed with hubs having. grooves therein adaptedto receive forked arms a, These arms are secured to the opposite side frames and are adapted to maintain the gears of each set in mesh with one another when the side frames are moved relative to one another to wrap rolls of diderent lengths. See Fig. 2.

The rotation of the transverse shaft 5* is controlled by means by an automatic clutch a ofeny automatic type adapted to form a drive connection at least for one revolution each time its trip lever is actuated. A well known form of this type of clutch is shown n Figs. 24: and 23 in which a cam'13 havmg a number of cam or inclined surfaces is keyed to the shaft e'". the cam is disposed a ring 14: having a plurality of slots containmg rollers 15 adapted to he received in a counterbore formed in a drivin member 19 which is journalled on the said shaft. A'

spring 18 tendin to rotate the ring relative to the cam and t us move the rollers u the mclmed surfaces for engagement wit the counter-bore is normally held inoperative by means of a trip lever 17 engaged with a lug 18 formed on t o ring 14. The lever may be provided w1th a spring 20 which tends to old it in engagement withthe lug. The sprocket 19 is constantly rotated as hereinafter described and is clutched with the shaft to drive it when the lever 17 is rocked to disengage the lug 18. When the clutch is thrown The inside headers z are carried at opposite into operation the parts thereof and the shaft rotate with the sprocket until the lever 17 is moved into the path of the lug and again engages it.

he lever 17 is connected by means of a rod 2'" with a bell crank connected with one end of a transverse rod 21 running across the machine below the guide frame 4; see Figs. 1, 3 and 5. The other end of this rod is connected with a crank arm secured to an os-- 6 e" on to its header plate 11'.

The header plates arepivot-ally and slidably mounted in slots formed in brackets i shaft 23" 18 provided with one or more crank 5 rocker shafts i" ment with the feed roller, the arm 1'" carried by the side frames 1 and are adapted to be; swung from their header receiving 0- sition shown in dotted lines in-Fi 9 an in full lines in Fig. 3 to a position or holding the headers against the adjacent ends of the roll B. This is accomplished by means of journal ed on the side frames 1' at o osite sides of the machine. Each arms i", each being connected with one end of a connecting rod z', the other end of which is pivotally connected with the plate. The shafts i" are partially rotated by the feed roller shafts z" near the end of their revolution so that immediatel the inside headers z are received on the has er plates 25 the latter are swun to position the headers a ainst the ends of the roll which is lyingon t e carrier rollers a and a. Each shaft 4, has an arm i" secured thereto which is ada ted to engage a hook i on a rod 1'" which is connected to an arm i.".secured to the shaft 2'". During that. portion of the revolution of the fee roller 1" in which the plrojection i is operative to hold the inside eaders from engageengages the hook i" toraise it and rock the shafti. The arm 1'" is rovided with a nose 6" ada ted, when the. ooked rod has been 'move 'a redetermined distance to engage the rod to force the hook i", agamst'the tension of a spring 2'", off the arm 1?.

The ivot' pins of the plates 2" are spring presse towards the inner ends of the slots in the brackets 2'. Cam members 2'' adapted to engage stationary parts 5 carried by the brackets are adaptedto draw the pivot pins 'towards the outer ends of the slots when the plates are swung to their. inclined positions. This arran ement prevents the lower ends of the plates om contacting with the roll R as it is rollin "on to the carrier rollers. As the plates are ing swung to position the inside eaders 23 against the ends of the roll the cam members 2'" permit the lower ends of the plates to be moved into close proximity to the roll ends by the action of the springs.

Body wrapper supply application One or more supply rolls of the body wrapper B are carried on rollers B which are j ournalled on a stationary frame 1', see. Figs. 1, 2 and 3. The free end of thesupily roll in use is suitably uided to and asse between two sets of fee rollers B w ch are journalled in bearings carried by supports B that are secured to the upper cross members 1 of the the gum roll.

stationary frame 1 and extends transversely of the machine whereby the feed rollers onv the shaft will slide thereon when the side frames 1' are being adjusted. One of the rollers of each set is provided with a lurality of substantially V shaped punc es B a apted to pass into complementary notches formed in the other roller. 'These punches are adapted to cut gusset shaped openin s and thus form flaps along the edges of tie wrapper see Figs. beyond th e ends of the news print roll R and are subsequently folded in over the Inside headersz as hereinafter described. To facilitate the folding of the flaps and to form neat ends on the wrapper, we form an are shaped crease at the base of each fla the radius of the are being substantially t e same as the radius of the roll R. These creases are formed by providing one feed roller of each set with are shaped ridges B, see Fig. 2. These rid es or pro'ections project only a very slight istance cm the periphery of the roller and the creases are formed 1n the side of the wrap er that subsequently becomes the underside thereof.

The shaft B and thus the-feed rollers are rotated, as hereinafter described by a motor 60, to feed suflicient wra per to obtain the desired number of turns thereof on the roll R. The notched wrapper passes from the'feed rollers throu h a slot 1n' a cutting table 23 (see Fi s. 1, and 3) on which a reciprocatmg'kni e B is mounted. This knife is connected by means of rods B with eccentrics B secured to the eccentric shaft B which is rotated by the motor 60 as hereinafter described. The wrapper then passes a gum roller B journalled in a. trou h B carried by the table 23. The roller ies within an o ning formed lengthwise of the trou h so t at normally it does not contact wit therocked, to bring the wrapper in contact wit late B extending transversely of the mac B ine is pivoted on brackets secured to the frame 1 9 and 26. The flaps extend and is yieldinglyconnected with arms B secured to the eccentric rods B Bars B slidably mounted on one side of the plate for engagement with the fingers B" are provided'with projections B extending through-slots B formed in the The slots are arranged at opposite ends of the plate and in ifi'erent planes whereby the bars when moved towards the engage a decreasing middle of the plate will overlie one another to decrease the number of fingers in operat on as hereinafter described.- The rock ng movement of the plate B caused by the rods B is less than the thickness of the bars B so that only v will be moved into engagement with the wra per. 7

T e width of or the distance between the sides of the gummed ortion, that are parallel to the notched si es of the wrapper, is varied as follows.

The cutting table 23 includesthree T-section members spaced apart to form two iongitudinal slots for the passage ofithe Wrasper, the members being secured together a acent their ends. The cutting table 23 and trough B are secured by supports 24 to the opposite sides of the frame 1 and are carried below the upper cross members 1 so that the side frames 1 may be moved to and from one another while the cutting table remains stationary. It is important that the gued portion of any widt of wrapper is such that there will be no possibilit of the s reading onto the ends 0 the roll We t erefore provide each side frame 1 with an inwardly projecting wedge bar B adapted, as the side frames are moved towards one an other, to move the bars B so that theywill number of gers B to decrease the widt of the med portion. The wedge bars are provi ed with notches adapted to receive the free ends of the pro jections B on the bars B, see Fi 3. To limit the inward travel of the bars fi when they are positioned over one another, we pivot the wedge bars on the side frames} and provide cams B* for engagement with the inclined or wedge shaped ends of the wedge bars whereby they-are thrown out of engagement with their projections B. When the side frames are moved awa from one another the wedge bars slide a ong their cams and re-engage the projections to slide the bars B outwardly to increase the number of fingers in o eration. It will be noted that the centra 1y located finger is much wider than the width of the outer fingers so that the bars B, when moved to their outer positions, will lie behind the outer fingers and the ends of the wide finger whereby all the fingers will be rocked by the eccentric rods.

When the side frames 1 are moved towards one another the bars B are retracted and both lie behind the wide finger so that the gummed portion of the wrap r will be sub stantially the same width as t e width of the wide finger.

The wrapper is guided by endless tapes 25 and 26, and guide arms 27 1nto the mp between the news print roll R and the carrier roller a.

The tapes 25 and 26 are carried on rollers journal ed on spindles carried in the fingers engaged by the bars to increase the wrappings at any suitable manner by the adjacent side frame 1'. tapes 25 and 26 are driven by a belt 28 from a ro ler 29 carried on the'ad'acent standard 12 and adapted to'frictional y rier roller a when it is in its Each of the guide arms 27 is secured to a spindle 30, on which one of the rollers for the Folding eh the entice the both/wrapper As the wrapper is being wound round the roll R, the flaps or tongues on op site on of the wrapper are turned or 0 dad in, by means of to ing devices 32 carried the in side header plates e', to lie at an e of to the main portion of the against the inside headers a, see F1 s 26 27, l and 8. Each device 32 is provide wit an inwardly curved upper side 32 adapted to be engaged by the oweredges of the flaps, seriatim; This upper side: is s seed from the plate 2' to provide a slot 32' $01. the passage of the flaps as theyare drawn downwardl over a face 32 which inclinesfrorn the curve side 32 towards the inner side of the device. In other words the flaps are first turned to lie against the outersides of the header plates and are then drawn through the slots 32 to lie between the inside headers dead the inner sides of the header plates. The flaps overlie one another slightly, are held in position against the insideheaders, Toy the inside header plates, during the wrapinafter described.

wrapper and Each set of rollers and thus the t guide arm in i its When suflicient body wrapper has. been fed I I by the feed rollers 18- to form about one and a half windings on the roll R, the feed rollers are stopped and the eccentric shaft B gum the tail end of the wrapper as hereinbeiore described." The is rotated to cut and wrapper is thus gummed on itself. The above mentioned feeding and cuttin mechanisms are automatically started Y an stopped as hereinafter described. v 1

Band wrapper supply and application Band wrappers b formed of narrow strips are wound on and glued to the body wra per i the ends" 0 the news print roll. The supply rolls of the band wrappers b are carried on cores .6 which are mounted for rotary and axial movement shafts 5", see Figs. 1 and 2. The inner end of each of these shafts is carried by a stationary bearing 5 havin an enlarged recess 5 adapted ,to receive a ead formed on the inner end of the shaft. The outer ends of these shafts are slidably mounted in bearings 5 carried by the upplerbcrogs members 1.

e an wrapper supthe side frames 1. Forked arms I)" secured to the bearings 5 engage suitablegrooves formed in the outer en s of the cores whereby the latter are moved transversely of the 'machine when the side frames are moved.

The free end of each band wrapper is passed between a set of feed rollers b which are similar to the feed rollers B hereinbefore described. The rollers b are journalled in bearin carried by supports 5 which are secure to the up er cross members 1. One feed roller of eac set is feather keyed on a transverse shaft 5 which is similar to and is carried in the same manner .as the shaft B.

The rollers of each set are geared to ether and one of them is provided with V- aped punches 5, while the other has complementary notches for gussetting the bands to form flaps or tongues along the edges thereof. These flaps are similar to the flaps or tongues on the body wrapper and are creased by the are shaped creasers b so that they will fold neatly over the ends of the body wrapper and lie against the flaps or tongues thereof. The cuttings from the gusset cutters B and b are forced out of the notches by ejector plates 85 which form movable bottoms for the notches, see Figs. 25 and 2. The plates are provided with inwardly extending pins 86 aving heads on their inner ends. Shafts 87 journalled in one of the feed rollers B and b of each set are provided with a rectangular cross sectional portion 87" adapted to engage the pins and actuate the plates on each quarter revolution of the shafts. Each shaft is provided with a four toothed ratchet wheel 88 the teeth of which are adapted to be engaged seriatim b a finger 89 carried on a stationary art 0 the machine to 've the ratchet w eel a quarter turn and t us actuate the ejector plates. The cuttings are dischar ed through openings in the supports B and b into chutes 95 for carrying them away from the machine.

The band wra pers pass from the feed rollers through a s ot in the cuttingv table 23 on which a knife 5' is-reciprocata 1y mounted (see Fi s. 7 and 9). Th1s knife is similar to the kni e B and is operated by eccentrics b secured to an eccentric shaft b" which is driven as hereinafter described by the motor 60. The wrap ers then pass gum rollers 5 v s which are fed om troughs 5 supported on frames52 that are carried on the side frames 1.. These gumming rollers are adapted to apply narrow continuous strips of gum-centrall of the ortions of the wrappers that over ie the ho y wrapper to revent the gum spreading beyond the edges of the band wra pers durmg the Fluing of the latter to t e ody wrapper. he flaps or ton ues on the band wrappers are turned in b t e foldingin devices 32 over the flaps on t e body wra per. Referring to Figs. 8 and 9 it will e noted that the tapes 25 and 26 are so located that they'engage the flaps to uide the wra pers into the nip between t e roll and th tapes 31 and therefore do not contact with the gummed portions of the wrappers. The tapes 25 and 26 thus hold the wrap ers so that they will be fed straight with t e arcshaped creases in alinement with the edges of t e roll.

Wrapper pressing ale vices To guide the free ends of the wrap ers B and I) round the upper portion of t e roll R and to facilitate the wrap ing thereof, we

= provide pressure arms 33 a a ted to engage stantially m alinement with the guide arms 27 and are adapted to guide the free'ends of the wrappers into the ni s between the tapes 31 and the roll R. Eac pressure arm is formed in three sections, the inner and outer sections 34 and 35 being pivoted on the ends of the middle section 33. These sec-' tions are formed of curved spaced bars having rollers on which tapes 36, 37 and 38 are so carried that the end sections may be swung on their pivots. The middle sectlon is provided with upward] extending arms 39 pivoted at 40 on a roc ing bar 41 which is secured to a shaft 42 journalled on an extension 52" of the gum trough supporting frame with a lever 47: that is fulcrumed on the rocking bar 41. The op osite end of the lever is pivotally connecte with one end. of a rod 48, the other end of which is pivotally connected at 49 with the extension 52 and is adjustable in length to properl position the part. As the pivot 49 is offset rom the shaft 42 the lever 47 is rocked to swing the outer section 35 upwardly when the arm'as a whole swings downwardly on the shaft 42 which occurs when the roll passes from beneath it. An arm 42 secured to-the shaft 42 is adapted to engage an abutment 42 to limit the down- The section 35 is pro- 60 I rollers.

To accelerate the speed of the roll R when it is discharged from the carrier rollers, a tilting table 54 comprisin leaves 54 and 5t" hinged at 54; is provided see Figs. 7, 21 and 22). The hinge pins 54 are pivotally mounted in hubs formed on the upper ends of arms which are swingably carried on a transverse shaft 56.

The leaves 54 are provided with anti-friction rollers resting on the periphery of the roller a and the leaf 54" is rovided with anti-friction rollers adapts to when it is in its raised position. Normally uide the wrappers overthe carrier rollers.

Fingers 6 secured to the guide arm spindles. 30 are adapted to sweep past the pawls when the] guide arms 27ers swung upwardly by the roll E. On the return movement of the guide arms, the fingers engage the pawls to actuate the rod i and thus -initial-position. his movement positions the hereinbefore described arms a so that they will swing the header plates inwardly against the ends ot the roll R during the next revolution of the feed rollers it and the move.

The shaft B and feed rollers B for the b is provided with a clutch c vtofthe clutch which is also 61 th ody wrappers B c hereinheiore described and, by the trip arm 11 e transverse rod 21. See Figs. 1, it,

normally held, by means oi a spring-20, in engagement with a lug 18 and adapted to be engaged byfi a win is connected in. age B 9 incluolin suitconnecting rods an bell cranks, with the lever 17.. The s rocket 19 of the clutch c is journalled on the shaft B and is constantly rotated as hereinafter described. whereby the shaft is driven when the arm B is pulled down to trip the lever 17 to disengage it from the lu 18. A pivoted \latch B is adapted to re easably lock the lever 17% when it is tripped by the arm B, to maintain the clutch 1n its 0 erative position for a predetermined num er of revolutions-of the shaft B It will be noted that the m B" is ada ted to move the lever only in t e direction s ring 11 will return the rod 21,

and arm after the roll arm 11. I

To release the latch B, and thus stop the wrapper feed rollers, and to operate the km e B we provide the following mocha-- nism. On the shaft B, is secured a helical gear B which meshes with a helical gear on athreaded shaft B that is suitably jour- B to their normal positions It has passed over the trip which is silara lever B on an arm B which which drives the gussetting I or tripping it whereby a linkage nalled on the stationary frame'l. A half nut B" slidabllay;

is adapted to engage the threads on the shaft so that it will be moved to engage a slide B" which in turn is ada ted to rock a bell crank B". This bell cran is ivotally carried between stationary bars and is connected by a rod B w1th the trip lever 17 of a clutch This clutch is similar to the clutch c and c and isadapted to form a drive connection between a constantly rotating ulley 19", journalled on the eccentric shaft 8, and the said shaft B. A s ring pressed plunger tends to hold the ever 17 b in engagement with the clutch lug 18 and also tends to restore the bell crank B and slide B? to their operative positions. The eccentric shaft carries a cam B" adapted after the nut B has tripped the clutch 0 to depress a pivoted arm B to which the vertically movable guide B is pivotally connected whereby the nut is disen aged from the threaded shaft :3 to enab e a welght B to return the nut to its initial position. To ensure the guide being held 4 down until the nut is returned, a plun er 13" having a pin and slot connection wit a spring pressed trigger B is ada ted to enage a notch in the guide B. he nut on its return movement strikes the trigger an thus disengages the plunger 13* from the guide. This permits a spring pressed plunger B to raise the arm B and thus the guide to reengz%e the nut with the threads on the shaft Immediately the guide B is depressed by the cam B to disengage the nut from the threaded shaft, the lunger 20 is free to move the trip lever 1 into the path of the lug 18 so that the clutch 0 will be thrown out of action after the eccentric shaft B has been driven one revolution. An eccentric B on the eccentric shaft is connected by a rod with a bell crank B which is adapted to rock the pivoted latch B out of engagement with the trip lever 17. This causes the clutch c to be thrown out to stop the feeding of the body wrapper B. During the revolution of the eccentric shaft B the eccentrics B are also operated to actuate the fingers B to move the tail end of the wrapper into engagement with the glue roll B and to actuate the knife'B to cut a length of body wrapper from its supply roll. The

'slide B is adjustable in length so that the distance of travel of the nut may be varied to var the length of the wrapper.

'I he eccentric B also controls the operation ofthe feed rollers b for the band wrappers b. The feed roller shaft 6 is provided with a clutch 0 (similar to the clutch 0) adapted to form a driving connection between the said shaft and a constantly rotating sprocket 19 journalled thereon. A spring 20 tends to hold the trip lever 17 of the clutch a in engagement with a lug 18.

An arm I) having a pin b" ada ted to engage the trip lever is'connected wit a bell number of revolutions of the shaft 6 The length of the band wrappers is regulated by mechanism similar to the hereinbefore described length-regulating mechanism for the body wrapper. The band wrapper mechanism includes a threaded shaft 6" driven by helical gearing b from the shaft b. A half nut I) carried on a guide Z) engages the threads of the shaft and is moved thereby into engagement with a slide b which is adapted to rock a bell crank b". a

The latter is connectedby a rod b with a trip lever 17 of a clutch c. This clutch is similar to the clutch a and is adapted to form a drive connection between a constantly rotating pulley 19, which is journalled on the eccentric shaft 6", and the said shaft B. This eccentric shaft is provided with a cam b d adapted to cause the return of the nut 6 after it has tripped the clutch c, in the same mannor as the nut B" is returned in the body wrapper length-regulatin mechanism. An eccentric 5 secured to t e eccentric shaft b is connected by a rod with a bell crank b" which is adapted to rock the pivoted latch 6 out of engagement with the tri lever 17 This causes the clutch c to be t rown out to stop the feeding of the band wrappers b.

To enable fresh rolls of wrapper pa er to be ositione'd in the machine and to to t e knives l3 and I)", manually operable levers B and b" are rovided for en agement with the pivote arms B an 6" of engagement with their threa ed shafts.

fed

During the revolution of the eccentric shaft b the eccentrics b are also operated to actuate the knife 72 to cut a length of band wrapper from each supply roll.

The carrier rol er a is lowered in the following manner: The eccentric b also controls the operation of the cams a for lowering the carrier roller a after the 'band wrap ers have been wrapped round the roll R. hese cams are carried on a shaft a which is journalled, below the roll a in the standards 12 and has its outerend journalled in a bearing located below the stationary frame 1. carried a clutch a (similar to clutchc) for forming a driving connection between the shaft a" and a constantly rotating gear 19' which is journalled thereon. The operation of the clutch 0 is delayed until the carrier See Fig. 3. On this outer end is rollers a and a have been rotated sufiiciently j to cause the free ends of the band wrappers, that have ust been cut from their supply rolls, to be wrapped round the news print roll, see Fig. 4. he mechanism for causing this delay is similar to the band andthe body wrap or length-re ulating mechamsms and inclu es :1 threader shaft'a driven by bevel eating a" from the shaft a of the constant- Fy rotating carrier roller a. A half nut a? carried on a vertically movable guide a is adapted to engage the threads on the shaft and is moved thereby into engagement with a bell crank a. The latteris connected by a rod a with the trip lever 17 a of the clutch c". A weighted lever we tends to raise the guide to engage the nut with the threaded shaft and this lever is normally held inoperative by a latch formed on the free end of a bell crank a. This bell crank is connected by a rod a, a bell crank a, and a link a with the bell crank b. When the latter is rocked by the eccentric I) the rod a is pulled upwardly to rockthe bell crank a which releases the lever a and causes the nut to engage the threaded shaft. When the nut engages the bell crank a, the clutch c is thrown in to rotate the cam shaft a for one revolution. To disengage the nut from the shaft and to rock the lever a into engagement with the latch on the bell crank it, we provide the bell crank a with an arm a adapted when the bell crank a is rocked by the nut to en age the end of the lever that is remote from t e weight. The nut is provided with a cord and a weight a for returning it to its initial position which is determined by an adjustable stop a. A sprin pressed plunger 20 returns the trip lever 1. and the bell crank a to their operative positions.-

The rotation of the cam shaft and thus the cams a lowers the carrier roller a to discharge the roll from the carrier rollers and then raises the carrier roller a to its normal position for co-operation with the roller (2 to receive a fresh news print roll.

The constantly rotating roller a,

clutch sprockets

19, 19 and 19, pulleys 19* and 19, and gear 19 are driven as follows. The shaft of a motor is connected by gearing 61 with the shaft a on which theroller a is carried, see Figs. 4, 2 and 3. The gear 19 of the clutch 0" on the cam shaft a is driven by a train of,gears 62, from the shaft a and this shaft is also provided with. two sprockets, one of which drives a chain 63 meshed with the sprocket 19 of the clutch o. The other sprocket drives a chain 64 meshed with both

sprockets

19 and 19 which are journalled on the feed roller shafts l3 and b. On the motor shaft is secured a pulley for driving a belt 66 which passes round the

pulleys

19 and 19 that are journalled on the eccentric shafts-B and b respectively.

The inclined outside header magazines 0 are carried on a frame 0 that is secured in any suitable manner to the forward side frames 1*, see Figs. 1, 2, 3, 10 to 13. Each ma azine is provided with a feed roller 0 wh1ch 18 secured toa shaft 0. The feed roll= ers o are each adapted to feed one outside header 0 from its ma azine during one revolution of the feed r0 er. To prevent more than one header from being engaged by a feed roller during its revolution, the circumference of the roller is slightl greater than the diameter of the header an the overlap thus fprmed on the roller is filled by a projectlon 0. This projection is adapted to en a hinged flap 0 on the magazine to hol t e stack of headers therein out of'engagement with the feed roller. On the next revolution of the latter the projection moves out of engagement with the flap and permits a follower 0 to present a fresh header to the feed roller. Each roller 0 is adapted to feed a header between a constantl rotating drum 0 and a platen. The drum as an annular gumming pad 0 carried on the periphery thereof. The shaft 0" of this drum and the shaft 0 are journalled on the frame 0. The in pad 0 is adapted to apiply a ring sha e' and of glue to the hea er and is supp icd with lue by a roller o running in a glue trough 0". This trough is carried on arms 0 pivoted on the frame 0 Springs 0 maintain a yielding frictional contact between the gumming pad and the roller 0 whereby thelatter is driven to feed an even supply of gum to the pad. The header is carried down etween suitable endless tapes 0 and two sets of rollers 0 into a guideway 0 The upper roller for carrying the tapes is driven by a belt 0 from the shaft 0 and the rollers 0" are so carried that they maintain a yielding frictional contact with the tapes, as for example by pivoting the rollers on the .upper ends of suitably fulcrumed levers 0 to the other ends of which the springs 0 are secured. The -uideway 0 is formed with an open side ad% with a channel shaped side 0 for guiding the edge of the header that is remote from the endless belt. The sides of the header are supported between uide members 0 and connecting rods 0 or carrying a vertically movable carrier 0 on which the header rests. The connecting rods are pivotally connected with a crank arm 0 that is rocked by one of a pair of parallel arms a. The latter are connected by a bar 0 adapted to be engaged by the periphery of the news print roll B as it is carried, by the conveyor 51, past the magazine. The purpose of this carrier mechanism is to automatically adjust the carrier so that the same sized headersma beused with rolls of different diameters an the center of the header will be positioned substantially in alinement with the horizontal center line of; the roll passing beneath the bar a The outside headers are each moved laterally past the open side of the guideway, by means of an ejector a", into the nip between acent the endless belt 7 0 and engage an arm of a bell crank o" to rock the latter and thus a lever '0" connected therewith. The lever is connected with the ejector o and is provided with a springer a weight for returning these arts to them normal positions. As the bel crank is located close to the underside of the roll, the distance betwen the point of contact of these parts and the vertical center line of the roll will be substantially the same for rolls having different diameters. The headers are thus e'ected to position their centers in substantial a 'nement with the center of various sized rolls.

The outside header feed roller shafts o are controlled by clutches c which may be similar to the clutch c and which include constantly rotating sprockets 19 and trip levers 17 These clutches are operated by the eccentrics b from a crank arm 0 formed on or operated by the bell crank a". The arm '0" is connected by a rod 0 with a crank on a transverse rocker shaft 0 This shaft is held in any suitable manner from axial movement and is journalled in bearings 0 carried by the guideway sides 0 These bearings carry grooved hubs feather keyed on the transverse shaft and provided with crank arms 0. The latter are connected byrods 0.," with the trip levers 17. When the side I frames 1 with their outside header mechanisms are moved away from or towards one another, the arms 0 are slmultaneously moved along the shaft 0 On the side frames 1" are journalled flanged drums 71 and spring pressed rollers 72 round which the endless belts pass. The lower ends of these belts are positioned slightly above the conveyor 51 to permit the belts to apply pressure to the outside headers of short news print rolls. The conveyor and belts are driven at the same speed. The journals of the rear drums 71 are driven, by sets of worm gearing 74, from a'shaft 73 which may be driven from any suitable source of power such as a motor 84.- that drives the conveyor 51. The shaft 73 is journalled on the rear side frames 1 and the worms are feather keyed thereon so that they may be shifted longitudinally of the shaft when the side frames are moved transversely of the machine. v

The side frames 1 and 1" on opposite sides of the machine are adjustable to and from each other by shafts 76 journalled in the guideways 1 and provided with threads for engagement with nuts carried by the 'side shaft 78 is ada ted to be driven by frames. The threaded shafts are simultaneously operated by worm gearing from a shaft 77 which extends centrally of the machine. A a belt 79 from any suita ly located shaft't at is constantly driven such as the shaft a and is ada ated, by means of a well known reverse mec anism that is controlled by a manually operable clutch 80, to drive the shaft 77 in either direction of rotation. To indicate the setting of the machine, each of the transversel movable supports B is rovided with an in icating, finger 91 adapte to run along a scale on a ar 92 secured to the stationary frame 1. v 1

The constantly rotating drum shafts 0 are driven by any suitableshafts and caring o from the drums 71 that are carriecf forward side frames 1". The sprockets 19' of the clutches a are driven by s rockets and chains 0 from the shafts 0 t is important that the feed rollers 0 be timed with the ummi'ng drums 0 so that 'the pads 0 will e correctly ositioned relative to the headers, as the are (1 East the drums, to apply the ring s aped ban s of In thereto. This timing may be accomphs ed by employing only;

may be substituted for the hereinbefore de:

scribed automatic clutches of the cam or wedging type.

To ensure the roll being centered relative to the outside header applying mechanism, we provide the runway 50 with anti-friction rollers adapted to run on transverse guides 50 so that it will readily and easily run transversely of the machine when it is carrying a roll R. If the roll is shifted slightly out of alinement when it is being discharged from the carrier rollers a and a one ofits ends will engage the adjacent inwardly directed wall 53 to cause the roll and runway to be shifted transversely of the machine as the roll passes by the by over the runway. The portions of the walls 53 which extend rearwardly of the runwa are substantiall parallel to maintain the ro l in alinement with the center line of the ma-' chine. On the guide is pivoted a weighted .pendulum 50 having a pin and slot connection with the runway. The pendulum is similar to the pendulum 5 hereinbefore described and is adapted to position the runway in aline- I lies the preceding fiapbut the free end of the flap beyond the slit overlies the preceding flap as shown in Fig. 26. In other words the slit permits one edge of the outer and innerportions of a flap to straddle the adjacent edgelof the preceding flap. The slits are formed in the flaps by lateral extensions B and 11" formed on the punches B and b respectively. The notches for receiving the laterare shaped to receive and to 00-0 erate with the extensions so that the material cut out to form the flaps and slits is integral and is adapted to be removed by the ejector plates 85 from the notches, as hereinbefore described. The free or outer ends of the fla s are directed or bent outwardly relative to t e base or inner portions thereof by a wedge block 32 carried on the plate 71'. The wedge blocks are located above the slots 32 and are inclined downwardly and laterally to prevent the flaps from being torn as their free ends ride over the blocks.

Any slack in the wrappers as they are being wound on the roll R is taken up by the tapes 38, 37, and 38 which are driven at a slightly greater speed than the peripheral speed of the roll Lt. One of the rollers journalled on the pressure mm section 33 is provided with a pulley which is driven by a narrow belt from a pulley journalled on the pivot 40. @n the last pulley is carried a second belt which passes round a pulley 96 on the shaft 42. This pulley 96 may be driven from any suitable shaft such as the shaft 7) which drives the gum roller 1) The gum on the outside headers 0 and the wrappers ii and b is dry by the time the roll ll reaches the end of the pressure belts. .ln some cases it may be desirable to provide short belts and to ensure the gum being set before the roll reaches the end of the short presser belts, we provide any suitable means for heating the belts. This may be done'by forming the spring pressed rollers 72 and the drums 71 as cylinders into which may be passed steam or heated air whereby the belt will be heated by contact with the heated cylinders. The lower journals of the rollers and drums are tubular for suitable connection with steam or hot air piping 97. The conveyor 51 then discharges the roll on to a scale platform 82 where it has its weight and other indicia stamped on. The roll is now ready for shipping and is passed on to a loading conveyor 83 that may be driven by chains 90 from the adjacent shaft of theconveyor 51.

Made of operation Assuming the side frames have been adjusted to suit the length of the news print roll to be wrapped and the slides 13 and'b have been adjusted to obtain the desired lengths of the wrappers, the mode ofoperation is as follows. As the roll passes on to the carriage 3 it engages the centering devices 6 which ensure the roll being alined and as it rolls over the carriage towards the carrier rollers a and a it depresses the trip arm 11 to start the inside header feeding rollers i and the body wrapper feeding and gusseting rollers B mm otion. The roll R then engages the outer sections 35 of the pressure arms to swing the said arms upwardly on their pivots 42 which causes the rods 46, 48 and the' levers 47 to swing the outer ends of the sections 35 downwardly into engagement with-the periphery of the roll. The plates 91" are swung inwardly by the shafts a" at the end of their revolution to hold the inside headers a ainst the ends of the roll R and to move the folding devices 32 to their operative positions for folding in the flaps on the wrappers. While the main function of these flaps is to protect the endsof the roll R, the flaps also serve to keep the main portion. of the wrapper in engagement with the periphery of the roll during the wra ping of the roll. With the feeding of the b0 y wra per the nut B is startet in motion towar s the tripping mechanism for actuating the cocentric shaft B which stops the feeding rollers 13 causes the wrapper to be gummed ands cut andstarts the band wrapper feeding rollers b. As the band Wrappers are'bcing fed, the nut 5 moves towards its tripping mechanism and when this is reached the eccentric shaft 7) is revolved once to stop the feed rollers, cut the band wrappers, start the mechanism for operating the cams a and start the outside header feeding rollers 0*. These cams lower the carrier roller a which permits the tilting of the table 54 to discharge the roll 1% therefrom; The wrapper guide arms 27 are then swung upwardly by the roll and on their return movement rock the inside header plates 2' to their positions for receiving fresh headers. As the roll passes over the runway 50 it is again alined. The outside headers are gummed and positioned on the carriers 0 during the lowering of the carrier roller a.

The roll R runs on to the conveyor 51 and raises the bars 0 which elevate the carriers and thus the headers to aline their horizontal center lines with the horizontal center line of the roll. The latter then engages the bell cranks 0 to eject the headers from the carriers into the nips formed by the ends of the roll and the adjacent pressure belts 70. The

headers are thus frietionally gripped between the belts and the roll ends and are drawn from their carriers and carried between these parts until the um is set. The roll is then wei hed and 1a lled ready for shipping.
