- To all whom it may concern:

nous overlapped shown m Be it known that I, Aoohrn MACH, a citizen of the United States, and a resident of Springfield, in the count of Hampden and State of 'Massachusetts, tain new and useful Improvements in W'rapping-Machines, of which the following is a specification.

This invention relates to improvements in wrapping machines and more particularly to machines wherein articles, such as chewing-gum, chocolate bars, soap, and the like, may be entirely inclosed in wrappers. as

arailin or wax-coated wrappers, and where m such wrappers may be entirely sealed, is by fusing the aratlin coating on contigaccs of the wrappers.

While the machine of the present invention constitutes in itself an operable wrapping machine for applying and sealing wrappers to articles, and is largely indeendent of the particular character of the articles it is nevertheless capable of and ads. ted for use with the so-called multiple stic wrapping machines, such as are shown in U. S. Letters Patent No. l,ll7,i-'i2, gamed Nov. 17, 1914, to Rcdingionnnd ilmoe. or in U. S. Letters Patent No. 1,133,668, grant 1 March 30, 1915, to Redington and Mi moc. 1n the first-named atcnt, the multiple-stick package is entirely mclosed in an outer wrapper and placed in a swinging transport-arm which conveys the wrapped package into position for the {IP- plication of an outer band or hinder. The present invention deals largely with llilprovements which may be substituted for the swingin transport-arm of the machine t e first of the ahove named patents, to accomplish not only the function of conveying the wrapped articles to the banding mechanism, but also to permit certain desirable operations, as the sealing; of the outer wrap er, to be performed prior to delivery oft e package to the banding mechanism.

An object of the invention is to provide, in a wrapping machine of the type wherein articles delivered from one mechanism are carried to another mechanism by a swinging lave invented certransport-anti, a :ehanism to he substituted for such an, .1 to perform a complete wrapping operet; it during the sssage of the article between the two named mechanisms, whereby an article or group of articles may be inc sad in an outer wrapper, and such wrapper sealed, if desired.

Another object of the invention is to provide in a wrapping machine, we swinging transporterms which are arranged to swing simultaneously through an e uai angle and are angularly as well. as axial y spaced, and a chute intermediate the path 0t such arms with which each may alternately aline, to-

ether with mechanism to transfer articles roin one arm into the chute and subsequently to deliver such articles from the chute into the other arm.

A further object of the invention. is to provide in a transfer chute of the class described, 11 combined folding and wrappersealing means, endfolding meclrianism, and devices to seal the end folds, together with means to move the articles step by step through the chute to be operated upon successively by said means, mechanism, and devices.

A further object of the invention is to provide specifically improved endfolding mechanism fern wrapping machine.

A further object of the ini'emticn is to provide in e wrapping machine generally improved mechanical structure.

Other objects and :ulvnntnpcs wili appear in the i'ollowing description and in the appended claims.

The invention, in an embodiment at present preferred, is shown for illustrative purposes in, the accompanying drawings, in which Figure 1 is a front elevational view of a wrapping machine embodying the invention. Certain parts of the invention, particularly the wrapper-feeding mechanism, have been shown as broken away to reveal other and more important parts;

The nnichine, in general, comprises an inlerinittcntly-operable swinging transportarm having a folding box therein; suitable feeding mechanism operable while the arm is at rest in, one position to position articles and their wrappers in such folding box and partially wrap the articles; devices operable during. the movement of the arm to fold other portions of the wrappers about the articles; a stationary chute with which the folding box alines when the arm comes to rest in another position; means to transfer the partially wrapped articles from the folding box into lhe chute and operable to apply other portions of the wrapper about the articles: oscillatory end-trucking fingers to complete the wrapping of the articles while in like chine: lira C111,::JICl COOhHg devices associated with the latter and operable sueeesairely on the wrapped articles as they pass. through the chute, a second intermittcnll'y-opcluble swinging transport-arm arranged when it comes lo rest in one position to aline with said chute to receive a wrapped and sealed package therefrom and operable to carry the package to a delivery point or to other mechanism, such as banding mechanism. for example: and means to remove the package from the second arm when it comes to rest in its other position.

The general frame structure of the machine will first be described. Referring to Fig. 1, A rcprtmcnts a bed-plate suitably supported by a frame B. Rotatably mounted in the latter is a shaft 20, which may be driven in any suitable manner and 1s arranged to actuate the several mechanisms of the machine. as will appear. Such mechanisms are either mounted directly on bed A or indirectly by means of brackets attached to the bed. Thus. adjacent the rear of bed A (Fig. 2) and attached thereto are three upstanding brackets a, 7) and c, which are arranged in substantial alinement and in spaced relation. Bracket (1 supports the mechanism for transferring the articles from the foldin box of the swinging transportarni into t 1e scaling chute, as will appear, and this bracket, largely broken away in F igs. 1 and 2, appears more completely in Figs. 3 and 5. Bracket 1) supports the transfer chute, and is best shown in Figs. 4 and 5. lirackct carrics the oscillatory enders and is also best shown in Figs. 4 and 5. Forwardly of the brackets a b and c is a pair of spaced upstanding brackets (1 (Figs. 1, 2 and 3) which are suitably mounted on bed A and rotatably support a wrapper-supply roll 21 with its axis in parallel relation with the mnin drive-shaft 20. Neal-the forward end of bed A and suitably fixed thereto is a bracket 6 (Figs. 1 and 2) which i'otatably supports a drive-shaft 22 for the wrap er-feeding mechanism, and this drivesha t is arranged parallel with shaft 20 which is suitably connected therewith, as by chains 23 and suitable sprockets. Substantially centrally of bed A and suitably fixed thereto is a table f on which the articles to be wrapped may be placed by any suitable means and adjacent the table and also fixed to bed A is a chute g which is alined with the table to receive articles therefrom. Slightly spaced from chute g is a second chute it, her *inafter called the fold-breaking box through which the articles and their wrappers may be fed.

The article-feeding mechanism will next be described with particular reference to Figs. 2 and 3. a plunger Bl which is rcciprocable along a line at right angles to the main drive-shaft 20 to carry the articles from table 7', into and thcough both of the described chutes y and I1. Plunger 24: is fixedly mounted on-a bar 25 (Figs. 1 and 2) which is slidably supported on bed A forwardly of the described chutes and It. Plunger 24 is actuated by a cam 26 on the main drive-shaft 20 (see F ig. 1) in the following manner: A lever 27, suitably fulcruined on frame B. as indicated in Fig. 1, and ha ving a roll to ride in a suitable path in cam '26, has its upper end connected by a link 28 to a lug on the under side of member 24. Cum 2.6 is so constructed as to move plunger 24 to the right (as viewed in Fig. 3) until its forward and articleengaging end lies substantially flush with the exit end of the described foldbreaking box It and then to return to the illustrated position.

It has been described that the articles may be delivered in any suitable manner to table 7. \Vhen the machine is employed for wra ping multiple-stick packages, such as sticks of chewing-gum or the like. for example, the means for delivering the articles into position for engagementby plunger 24 may be of the type shown in the second of the above-named patents, and the table f may obviously be omitted, if desired, to permit.

Such mechanism consists of a ways patent. The invent'on. however, is in. pendent of the article-delivering meow :11- though it is readily capable of 1251*. with s 1;

means as are shown in the lest-Emailed 1m? ent, if desired.

.The wrapper-feeding locum will next. be considered with reference to l ig. 3. The wrapping material in this iur lnnoc consists of a paraliined or wax-coated paper, or any other suitable material whirl. may be $1 i by the application of heat. The wrap 7 nmteriel supplied in e rominuone Gilli! l. which is wound on the rleectihed roll ill. Strip is led from roll over suitable guide-rolls :29 to and between a pair of coucting feed-rolls 30 and thence into a. chute j. A second pair of counting feed-rolls 3% are operable to grip the strip while in chute j,' and from rolls 31 the strip posses downwardlx through and below the chute j into the space between the chute g and foldbrcaking box It. A. knife associated with one of the rolls 30 is operable to the strip into wrappers of suituhle length which mev he carried with the articles into box 3:.

The invention is independent of the par ticular type of wrapper-feeding mechanism employed, and that shown is given merely as an illustrative example of one known and suitable type. Since the invention is not concerned primarily with the wruppcr fceding mccllmiisln and since such nicclnmieins are now well known in the art. the present. illustration has been confined largely to a conventional or diugrunuouticul .llflil'iiig of the wruppcnfeeding nu-rllunisni, For exumplc, the driving conncclions for

rolls

30 and 31 have not been illustrated inasmuch as they are unnecessary to on understanding of the present invention. it lining undo-n stood. that rolls 30 and Eli. may be geared up to the described Shaft to suitably feed the wrappers i, without requiring the exercise of inventive skill.

The swinging trnnsportmrm and its fold in box will next lie described. Referring first to Figs. l; and 3, the transport-arm is; indicated by reference numeral 33 and is suitably connected at one end to a she ft 3 which is mounted for oscillation in suitable spaced bearings secured to bed A, as shown in Fig. 2. T he shaft 34 in arranged with its axis at right angles to the xnuin drive-shaft 20 and passes through the described bracket b. as shown in Fig. 4. In Fig: l and 2 the transport-arm is shown in Ulla: of its posiions of rest, wherein its folding box to be described elines with and forms a continm ation of the fold-breaking box h. In Fig. 5. the transport-arm is shown in its other positionof rest in readiness for the delivery of the partially Wrapped articles to the sealing chute, as will later appear.

The detailed construction of the transport-arm 33 and its folding box is shown in Figs. 7 and 8. to which referenm will. now he made. it has been mention thut the no 33 suitably ififil'lllQClBll to shaft 34.

Further movewrapper on entering the folding box is 611- gaged b the surface 38 and adjacent its ends by the top plates 41, which lay the wrapper about one side face and top and bottom faces of articles is. as shown in Fig. 9. leaving an extension Z to be subsequently l folded against the other side face and later overlapped with the edge of wrapper on the bottom face of the articles. The wrapper is wider than the articles are long whereby there are other wrapperextensions to be 30 folded against the. ends of the ai'ticles. The first fold of such end extensions is acco1nplished by the described blocks 40 which lay the wrapper against the articles, as indicated at In in Fig. l), leaving upper and lower end extensions n to be subsequently folded, which extensions are received in the described recesses 13. Although the plates all do not extend entirely across the upper face of the articles, they nevertheless extend sutliciently to hold the upper portion of the wrapper 1 while the end tucks m are being made. In making such end tucks, the tendency is to throw the portions n (Fig. 9) upwardly about the end edges of the articles as an axis.

3 Such upthrow is prevented by the engagement of the plates 11 both with the portions n as well as with the port ions of thewrapper adjacent the portions n and overlying the articles. It is to be understood that the folding operations may be accomplished in box h by parts exactly similar to those described in connection with the transport-arm folding box.

The transport-arm 33 is movable from the position shown in Fig. l to that shown in Fig. 5 by the following mechanism: A pinion 44 (F ig. 2) is fixed to shaft 34, and in mesh therewith is a vertically-slidable rack bar 45, the upper end of which is suitably guided in frame A (Fig. 2). Referring now to Fig. 3, a bracket 16 secured to the lower end of the rack-bar 45 functions to hold the latter against the main drive-shaft 20 as a supplementary guide and is provided with a roll to ride in a suitable cam-path 47 formed in one face of a cam-disk 48'secured to shaft 20. (am-path 47 is so constructed as to swing arm 33 in a clockwise direction (as viewed in Fig. 1) after the partially wrapped package has been deposited therein and to move the arm into the position shown in Fig. 5. The arm 33 is held thus ositioned for an interval suflicient to permit removal of the package and then is swung counterclockwise back into the position shown in Fi 1. As shown in F ig. 1, the lower face 0 arm 33 abuts bed A and thus arrests the arm when it becomes accurately alincd with box h, irrespective of continued movement of shaft 34, which is rendered ineffective by reason of the yieldable driving connection '36 and 37 described. Similarly, arm 33, when in its other position, abuts a stop 49 on the described bracket 6 (Figs. 4 and 5) for a like purpose.

The folding means operable during the movement of arm 33. will next be described.

Referring first to Fig. 3, it will be seen that the wrapper extension 1 lies in the folding box it at the time when arm 33 commences to swing upwardly. Consequently, the top walls of folding box Ia. function to, partially lay extension 1 against the remainmg side face of articles is, as the arm moves upwardly. The extension l, thus partially folded, is laid closely and flatly against the articles, as shown at 0 (Fig. 10) by a folding blade 50, leaving an extension 19 to subsequently be laid against the bottom face of the articles. The blade 50, as shown in Fig. 1, is attached to the described bracket 5 and, as shown in Fig. 3, lies in the path of the extension Z, whereby the 'latter may be laid down as the arm moves into its upright position.

The chute into which the partially wrapped package is carried from arm 33 will now be described with particular reference t 'Figs. 4, 5, and 6. The described bracket 6 has a flat plate-like portion 51, one face of which alines with the surface 38. on the arm 33 when the latter comes to rest in its upper position. .Plate 51 constitutes partof one wall of the transfer chute, and the remaining part consists of a heater plate 52, which, as shown in Fig. 4,. is set into a suitable opening in plate 51 near the entrance end hereof, leaving upper and lower slots 51'. ate 52 may be heated in any suitable mannbr, for example electrically, and a conventional representation of an electric heating coil is shown at 53 in F ig. 4. The plate 52 has parts which loosely encircle two vertically-spaced studs 55, which are fixed to plate 51, and the plate 52 is yieldably held in the illustrated posi-, tion, wherein stops 56 thereon abut the bracket Z, by springs 57 which are coiled around studs 55. In Fig. 4, only theupper portion of the plate 52 is shown, and comequently only one stud, spring, andr'sto appear, but it will be readily understo that the lower end of member 52 is constructed similarly to its upper end, the lower and being purposely bro en away to reveal other novel features.

Suitably fixed one above the other in vertically-spaced relation on plate 52 are two dovetail-shaped blocks 58 with which the described blo KS 40 are adapted to alirie 130 when the arm 38 is in the position shown in to the path Fig. 5. The lower block 58 has been shown 24, is a plu as broken away in Fig. 4. Pivot/ad to the engaging pl block 58 and loosely encircling studs 59 on ed by a link I the latter, are plates 60 (the upper plate 72,315 best being shown in Fig. 4 and the lower plate to Fig. 1, w 1n F1g. 5) which are yieldingly held bv showmit wil coiled springs 61 against the blocks 58 {tilt aily sup which function similarly to the described 2'3.

The edges of the wrapper then overlap and such overlapped edges, by engaging the heated plate 52 are joined together by the fusion of their wax coatings in a now well-known anncr. C0- incidentally with the t'oldin g of extensions 10, end folds, as'at q in Fig. 11, are made by the blocks 58, and such end-folding operw tious leave the upper and lower end wrapper extensions 11 in the form shown in Fig. 11. The extensions a lie in recesses it formed by the dovetail construction of blocks 58.

After the overlapped seam of the wrapper on the under face of the packagelias been sufliciently heated. the plunger moves the package into its second position, wherein it is engaged by plate 51. The latter functions to cool the heated portions of the wrapper and thus set, the fused coating material. The pairs of end wrapper extensions 12 then lie on opposite sides of a finger 63 and project thereheyond ready for foldingin a manner to be described.

It has been shown that the package ejected by plun er 70 is left in the position just described until the transport-arm 33 n'ioves into its horizontal position. Consequently, the folding of extensions a may advantageously be accomplished by means which are actuated from the transport-arm actuating mechanism'itself. To this end, the reciprocable rack-bar 45. already described as actuating the transport-arm. has an upwardly-extending bar thereon which is suitably fixed to a block 76 mounted to reciprocate vertically in suitable ways formed in the upper part of the describedbracket c. as best. shown in Figs. 4 and 5. The bracket 0 has a portion r, which is forwardly arched over and spaced from tll0\Sll(lfll)l0 block 76, as shown in Figs. 4 and to afford a bearing for one end of a shaft 77. the other end of the shaft being journaled in the main portion of bracket c as shown in Fig. 5. Fixed to the shaft 77 and adjacent the portion 1 is a depending arm 78 which lies in back of the plate 51 and is offset as indicated so as to lie. directly behind that. portion of plate 51 which is occupied by the package when in its second position. The. slots 51' already described are extended as indicated in Fig. 5 to permit the entrance of two spaced fingers 7.) n arm 78. which fingers are so spaced as to simultanemisly engage an upper and a lower extension 11 and fold it over the described fingers 63 which engage the ends of the package. Loosely mounted on shaft 77, with its hubcontiguous with that of the arm 78, is an arm 80 which extends downwardly to lie in front. of the plate 51. Arm 80 has two spaced end-tucking fin gers 81 projecting therefrom toward the fingers 79 and the fingers 81 are movable similarly to the latter but in a reverse direction to lay the remaining upper and lower extensions 1: agalnst the fingers (i3 and 1n overlapping relation with the first folded of the upstanding end folds n from the first,

into the second position of the package. It will also be noted that the rat-lobar 45 moves upwardly to swing the transport-arm 33 from the position shown in Fig. 5 to that.

shown in Fig. 1. The cam'block 76 will thus be moved upwardly. and cam-path is so constructed as to move its arm 78 inwardly so that its fingers 79 enter slots 51' and make the end folds described. during the first half of the interval required th return the transport-arm into the )osition shown in Fig. 1. It will be obvious rom an inspection of Fig. 4 that the cam-path Bl is so constructed that; its arm 80 is held stationary during the interval described. in the second half of the interval required to move the transport shown in Fig. 1. both cam-

paths

84 and 85 are constructed so as to swing their arms 80 and TS in the same direction-hamely. clockwise. as viewed in Fig. 4. Thus. fingers 7 will he carried away from the ends of the package while fingers 81 move into ('HL'HQT" mcnt therewith. it is to be noted that the

arms

80 and 78 also move in unison so that the fingers 81 and 79 which now almost touch each other are carried in this relation while the second pair of extensions 21 are being folded. Thus. the first extensions n are held until the second extensions a may he laid by fingers S1 in overlappin; relation againstthem.

Thus. at the timcwhcu transport-arm 33 arrives in the position shown in Fig. 1 and during its period of rest in this position. the overlapped folds inare held by fingers 81. It has also been described that while the transport-arm 33 is at rest in its horizontal position. the plunger 70 is advanced to remove the package. the end folds of which have just been completed. into position to be engaged by the surfaces 66. In thus moving the package. its end folds are held in position during the transfer by fingers 81. so that 'folds n ride smoothly in under the sur-. faces 66. It is therefore particularly useful and advantageous to have the fingers 81 dwell in their inner posit-ion durihg the de scribed transfer of the articles, but after such transfer the dwell of the fingers 81 is no longer useful and, if continued, would interfere with free passage of the upstanding endl'olds; n. of an incoming package. It thus becomes essential to spread apart arms: 78 and 80 into linpositions illustrated in Fig.4.

Such positioning of

arms

78 and 80 is acrol'nplisln-d in the following manner: As the transport-arm 33 starts upwardly, rackbar 45 moves downwardly and thus moves block 76 downwardly. This results in a reversal of the described movements of

arms

78 and 80. That is, the fingers 81 are carried out of slots 5] and away from the plate 51, while the fingers 79 a vanced toward plate 51, without, however, performing any useful function. As the transport'ai'm 33 arrives half way on its upward swinging movement, the fingers 81 are in their outer positions, while fingers 79 are in their inner positions, and during the latter part of the upward swinging movement of transportarm the fingers 81 are held in their outer positions while fingers 79 are gradually llpoved outwardly into the position shown in lifter the described operations of the endtucking fingersgthe plunger 70 is actuated to advance the package from its second and end-folding position to its third position, wherein the overlapped end folds in are engaged by the heated surfaces '66, whereby the wax coatings of the wrapper may be fused to seal the overlapped end folds. Due to the several thicknesses of the wrapper at the ends of the package, a longer interval of heating is re uired than is necessary for the overlapp longitudinal scam in the wrapper This is accomplished by leaving the package in the third position, to be removed therefrom by abutment with a succeeding andincoming packa e, rather than to remove the packa e direct y by the plunger. Thus, the pee a remains on plate 52, but a short interva, but the package is held by arms dunng one complete cycle of operation of the machine, whereby i;

eend folds m and n may be thoroughly heated to obtain a firmlysealed joint.

The means for carrying the wrapped and sealed packages from the end-fol 'sealmg devices} will now be described, Such means consists simply of a second transport-arm d7 which is yiel'dably connected to shaft 34 in the same manner as the trans ort-arm 33.

The arm 87, however, merely as twoo posed pairs'of jaws 88 between WhlCll t e wrap ed and sealed ackage may be 1pserte as shown in ig. 4. As shown m Fig. 5, arm 87 isimounted on theopposlte side of bracket b'froin arm "38 and is mounted at right angles to thedatter so that when arm 33. is in the position shown 1n Fig. 1, arm 87 is in upright position and jaws 88 form a continuation of the chute described. Thus, the )ackage removed from the end-fold sealing devices is positioned in arm 87, and the surfaces 89 thereof act to cool the heated portions of the wrapper and set the fused coating material thereof. It has been described that, while the transportarm I 33 is positioned horizontally, the plun'gcr adyances on its third step of movement to carry a package from the end folding mechanism into the cnd-fold-seal.ing devices. At such time, the arm 87 is at rest and positioned vertically so that the packa c in the end-fold-sealing devices is moved Ey abutment with the incoming package into the jaws 88 of arm 87. Thereafter, the latter is swung downwardly as arm 33 swings upwardly to carry the wrapped and scaled package a into the position shown in Figs. 2 and 4.

The package 8 may be removed from the transport-am 87 by an suitable or desirable means. For example, the means shown in the first of the above-named patents may be employed to remove the package to suit-- able banding mechanism, such as shown in such patent, or any other suitahle type of ejecting means may be employed to deliver the package to any other suitable mechanism for the invention is independent of the por ticular mechanism to which the wrapped and sealed packages are delivered. In the drawings, there has been shown a table 90 upon which the arm 87 comes to rest in its lower 'position, and as an illustrative example of one operable, although not necessarily preferred, means forremoving the packages 3 from arm 87 and depositing them upon table 90. 'the following means have been illustrated: Referring to Fig. 2, a plunger 91 is mounted to slide on a guidear 92 fixed to bed A, in a direction parallel with those lungcrs heretofore described. A lever 93, ulcrumed intermediate its ends on the described stu-b-shaft 73, has its upper end connected by a link 94 to the plunger. Referringnow to Fig; 1. the lower end of lever 93 carries a roll which rides in a suitably designed path-eam 95 fixed on the main drive shaft 20. Cam 95 is constructed to actuate lever 93'through one complete cycle while the arm 87 is at rest in its horizontal position. Thus, the plunger ma be advanced to eject packages .9 on tab 0 90 and thereafter, retracted into the illustrated position before arm 87 commences itsupward swinging movement.

The operationof the machine wlll now be briefly. summarized. Articles to be vvre pad, either singly or in grou s, as 'desl are fed against wrapper i, in and throu box of the transport-arm 33, while the latter is at rest in its horizontal position, by the the. fold-breaking box It and into the oldiug fform shown in Fig. 9. The arm 33 is then swung upwardly and, as it moves into its vertical position, the blade 50 lays down the wrapper extensions 1, the wrapping then up peering as shown in Fig. 10. After arm 83 has come'to rest in its vertical position,

plunger 70 is advanced to carry the article and wrapper into the combined folding box and heater, and, as they enter, plate 52 and blocks 58 act on the wrapper as described, leaving the wrapping in the condition shown in Fig. 11. At the same time, the plate 52 fuses the wax coating of the longitudinal overlapped scam in wrapper i and after the elapse of a sufiicient interval for the function, the plunger 70, which has been held stationary, advances another step to carry the package into osition for the end-folding operations. he plunger 70 is held sta: tionary during such operations and the latter occur while the arm 33 swings downwardly into position to receive another artit-lo and its wrapper. During such interval,

the fingers 79 are first moved inwardly to lay down one upper and one lower extension n and then the fingers 81 are moved inwardly to lay down the remaining extensions n, while the fingers 79 retract in such a manner that the first folds n are not released until the second folds n have been overlapped uponthem. The fingers 81 re-- main imthcir inner positions to hold folds n while arm 33 is at rest in its horizontal position. During such period of rest, the plunger 70 is advanced its third and 'last step to carry the more completely wrapped package into the end-fold-sealing devices and to remove from such devices into the arm 87, which is now at rest in its vertical position, the package heretofore positioned in the endfold-sea'lin devices. The plunger 70 is then retracte before arm 33 brings a succeeding article andits wrapper into lposition for insertion in the transfer -c ute. Meanwhile, a package remains in the endf ld-sealing devices for a com lete cycle 0? operation of the machine, w iereby the heated surfaces 66 may have ample time to effectively join the overlapped end folds m. and n. The scaled package ejected into the transport-arm 87 is carried to, table 90, and while the arm dwells in such position,

the package is ejected by the plum or 91.

Furthermore, I have provided a mechanism which may advantageously be interposed m known forms 0 gum-wrapping machines between the stick-grouping and package-banding mechanism to effect a similar function.
