Application filed May 21, 1917. Serial Ito. 165,831.

To all whom it may concern:

Be it known that We, JOHN S'rnornnn Fnnnimn and Vr ILLIS L. lVonTnAM, citizens of the United States, and residents of Jersey City, in the county of Hudson and tate of New Jersey, have invented certain new and useful Improvements in VVrapping- Machines, of which the following is a specification.

This invention relates to wrapping machines, and while we have in the present instance shown it as particularly adapted for the wrapping of small packages, such as boxes of cigarettes, we wish it to be understood that it is not limited in its useful application to this particular purpose, as it may be employedin other connections and under other conditions where its use may be deemed advantageous or desirable.

in carrying out our invention it is our purpose to provide a machine through the agency of which an article, such as a package, carton, box or the like may be rapidly and automatically enveloped in a wrapper sheet or cover blank in such manner as to thoroughly protect it against deterioration, soiling and contamination. In this connection, we wish to state that in the wrapping of small packages of goods that are likely to be unfavorably affected by atmospheric influences and changes, such for instance as cigarettes, we prefer to employ wrapper meets or cove blanks made from transparout or glac paper so that the boxes or containers will not only be completely and uniformly covered or wrapped so as to present a neat and attractive appearance, while being thoroughly protected against the admission or" air and of such foreign substances as might tend to injure or damage the goods, but the boxes themselves may be readily inspected through the transparent wrappers or covers, thus enabling the character and brand of the goods to be determined at a glance by means of the markings, color and other indications appearing on or exhibited by the boxes holding the merchandise.

, It is also our purpose to provide a wrapping machine which is automatic and selfeontained in the sense that the various steps or stages in the wrapping operation, such as the sequential or successive delivery of packages into proper position to be wrapped, the application of adhesive or sealing material to the wrapper sheets, the feeding of the wrapper sheets into proper position relative to the packages, the folding and sealing of such sheets about the packages and the final discharge of the latter in completely wrapped and sealed condition is automatically accomplished by a single or unitary machine which requires but little care or attention from the single operator who may be designated to run the machine.

Another object of our invention is the provision of a machine of this character wherein great quantities of packages or boxes may be economically, speedily and efiiciently wrapped, and which machine may be installed and operated at a relatively low cost.

lVith the above recited objects and others of a similar nature in view, our invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings,

Figs. 12, 13'and'14 are detailviews showing the successive steps in the folding of thcwrapp'er about the package.

Fig. 1-5 is a perspective view showing a completelywrapped and sealed package.

Before entering into adetai'le'd description ofout'invention, we will'briefiy state that in the form shown herein it embraces among other features a traveling carriage on which is mounted a package magazine-in which the operator places a stack or pile of the packages to be wrapped, such as boxes of cigarettes, the duty of the operator being to replenish the supply in the magazine as may be necessary. The lower end of the magazine opens into a chamber in which reciprocates a pusher block which takes the lowermost package fromthe magazine and pushes it into a carrier head mounted on the traveling or reciprocating carriage. This carrier head is also-provided with asuitable number of'glue pads, which, when'the carriagem'oves in one direction, in the present instance toward the left as shown in-Figs. 1 'and'Q, are brought'into contact with suitable wallower rollers working in 'a bath of glue in -a glue tank, the glueor adhesive being th-us'appliedto the pads. As the carriage moves away from the glue tank, or toward the right, these-glue pads are brought into contact with and pick up the top sheet from a stack or pile of wrapper sheets mounted upon a suitable self-adjusting support. As the carriage continues ltSlIlOVE- ment toward the right of the machine, considering Figs. 1 and 9., the before mentioned 'carrierhead, now holding a package to be wrapped, and a wrapper sheet which is held by the glue pads directly" beneath the package, is brought to'position above aforming well. Thiswell is preferably in the nature ofa box-likecasing or chute, the upper portion thereof being vertical or straight while the lower portion-is curved in the form of an elbow to constitute arelativelylong passageway to a point of diSchargeQthe chute being preferably so constructed for the purpose of causing the packages to take a long, s'low path of travel, thus permitting the drying of the glue on the sealed wrappers. Whenthe carrier head arrives over the upper end of the forming well the box and shown in Fim-13, after which, in due course,

the overlapping portions "on top of the box are folded downward by a plunger-like reciprocating folding head, asillustrated in Fig. 14. Then as the box is subsequently forced down into the folding well the remaining-outstanding portions of the wrapper are folded upward and pasted to the previously folded portions at the ends of the boxesso that the completely covered and wrapped box will appear as shown in Fig. 1-5. The "completely Wrapped and sealed boxes thenpass down the delivery chute as shown in Fig. -1.

Referring now to "the accompanying dra ings in detail,and.particularly to Figs. 1,2and '3, the letter A indicates the frame of the machine which includes the bed or table B and the backwall C. The power shaft of the machine is indicated by the nu meral l and is mounte'din suitable bearings 2 at the rear of the frame A. This shaft 1 is provided at oneend with'the usual fast pulley S and the loose pulley 4f, the shaft of course being 'adapted to -be driven, as will be well understood, by a belt running over the pulley 3 and whichbelt may be shifted as 'desired'to the pulley-4t, to throw the machine out of operation; On the power shaft 1 isa gear pinion 5-which meshes with and drives the large gear wheel 6 on the cam shaft '7 which extends approximate y parallel *ith and above the i 'aower'shaft 1- at the rear of "the frame, this shaft being mounted i n suitable hearings 8. 0.1 this cam shaft 7 and at approximately the center thereof isimounted the large drum 'cain '9 having the circumferentially extending eccentric cam groove 10 into which pro 'ects the stud 11 carried bythe carriage shifting arm 12 which reciprocates or shifts the carriage D, aswill be hereinafter understood. The "lower end of the arm 12 terminates in a sleeve 13'Inounted to rock on the stud shaft 14 carried'b'y theback wall-of the fraine and the upper end of this' arm-12 is connected through a suitable flex ble or link c'ouplin'g15 with the-strides extending from the 'bac'k of the-carriage D, as will be readily understood by reference to Fi s. 3 and 7, sot-hat when the drum cam 9 is revolved a reciprocating sliding motion will be i111 parted through the arm 12 to the carriage D. To permit of this we provide the back wall G of the frame with a pair of spaced parallel tracks or guides 17, the grooves 18 of which receive the parallel tapered flanges 19 of the carriage, these flanges fitting loosely in the grooves so as to permit of the free sliding movement of the carriage.

Suitably supported by and traveling with the carriage is a hopper or magazine E, which in the present instance is of rectangular or box-like form to receive the packages F which are to be wrapped, and which in the present instance may be considered as boxes of cigarettes. The lower end of the magazine E opens into a shallow elongated chamber 20 in which reciprocates a pusher block 21. When the pusher block is positioned in the forward extension 22 of the chamber 20, there will be no support to prevent the dropping of the packages F to this chamber 20, and consequently the lowermost package will descend into this chamber and rest upon the bottom or floor rails of the latter, as will be understood by reference to Figs. 3 and 5. T-lowever, when the pusher block 21 is shifted rearward of the machine, or from the extension 22 of the chamber to a position directly beneath the magazine, it will take the bottom package which we have shown at F in said Figs. 3 and 5 and push the same into the carrier head 23 which partially forms a rear section or continuation of the chamber 20, and in which is reciprocated a plunger for forcing the package out of the head as will be seen by reference to Fig. 4, and

4 which will be hereafter described in detail.

In order to reciprocate the pusher block 21 to accomplish the feeding of the packages from the magazine to the carrier head just described we secure a cam strip or bar 24 to the front face of the back wall C of the frame, as will be understood by reference to Fig. 2, this strip being preferably in the nature of a thin flexible barof metal, such as steel, and for a portion of its distance it is inclined outwardly relative to the back wall of the frame, and then near its outer end extending substantially parallel with such back portion of the frame and is connected therewith by a short rod, as shown at 24. As will be seen by reference to Fig. 5, this cam strip guides the bracket 26 which has a pair of rollers 27 which embrace the cam strip. This bracket in turn forms a connection with the sliding yoke 28 of the pusher block, the parallel arms 29 of the yoke projecting through openings 30 in the end of the carrier head and slide in grooves 31 in the side bars 32 of the head as will be understood by reference to Fig. 4, these yoke arms 29 being connected with or form a part of the sides of the pusher block 21. Furthermore, these yoke arms 29 are longitudinally slotted as at 33 and through these slots project short pins 34 carried by leaf springs 35; the pins thus yieldingly engaging the sides of the package to assist in maintaining the latter properly positioned in the carrier head and beneath the plunger thereof. As the bracket 26 slides along the cam strip 24, with the travel of the carriage a sliding movement is imparted to the pusher block 21, the block moving toward the back of the machine to place the package in the can. rier when the carriage is moving toward the right in Fig. 1, said block moving in the reverse direction or toward and into the chamber extensions 22, when the carriage is traveling toward the left. When the package is pushed into the carrier head it rides over and rests upon the yieldingly mounted spring-tensioned plates 36 which while they are horizontally positioned support the package and prevent its falling from the carrier, but will under pressure exerted by the plunger G against the package yield downward to permit the latter to escape, as shown in Fig. 10. As will best be seen by reference to Figs. 1 and 10 at 37 is shown a stop and guide for one end of the package and 38 shows an adjustable stop and guide for the other end of the package, these stops 37 and 38 also serving to position the wrapper sheet as will hereafter appear. The wrappers are shown at P, and are preferably in the nature of rectangular sheets of transparent or glac paper, especially when intended for the wrapping of cigarette boxes, and in Fig. 9, we have shown a stack of such wrappers positioned on a table or support 39 mounted on the upper end of the post 40. In order to insure that the top wrapper of the stack will always be in proper position to be withdrawn for application to a package, irrespective of the decrease in the thickness of the stack of wrappers when the machine is in use, we provide for the automatic and intermittent or step by step elevation of the wrapper support or table, by forming a longitudinally extending flat face 41 on the post 40 against which bears a clamping pin 42 mounted on a small rocking stud 43, rocking in the sleeve 44 of the post block or bearing 45, the post passing through a vertical bore 46 in this bearing. The rocking stud 43 is carried by an arm 47, the outer end of which is pivoted at 48 to a shank 49 which extends vertically to the bore 50 in the free end of the cam lever 51. This lever 51 is fulcrunied at 52 and at its rear end carries a cam roller 53 which rides in the groove 54 of the cam disk 55 on the cam shaft 7. At the proper time in the rotation of the cam 55 the forward or free end of the cam lever 51 is elevated striking the head 49 of the shank 49 and which head in the present instance comprises a pair of nuts, and lifting up on the shank 49 will rock the stud 43 to momentarily Withdraw the clamping pin from contact with the fiat face 4;1=of thepost 40, and as the lower endof thepost is linked as at-56to the *hand lever 57 pivoted at 58 -on:the frame A, the adjustable weight 59 at the rear end'of the lever will exercise power to push upward on the post tOand thus relevate the stack support. The continned-movement of the .cam 55 will move thelever 51 downward away from .the head of the shank 49 and the :spring vtensioned stud-.60 connected with the-arm 4:7'between the rocking stud 43 and the shank .419 will immediately act on this arm 47 and pull the same downward .to cause the clamping pin 42m again engage the post 40 and-holdthe stack support stationary against the.influence of theweight 59. In other words every timethe clamping pin 42 moves away from the post 40-the. latter will be shifted upward by the action of the weight 59 while withthe restoration ofthe clamping action of thepin 42 thepost with the stack support will be clamped against movement. When it is desiredto completely lower the stack table or support, as when placing anew stack of wrappers thereon, the operator may grasp the handle 57 of the hand lever 57 and clepressing the handle against the actionof the weight 59, may lowerthe table, or support, aswill be obvious.

For the purpose of maintaining the wrapper-s. in an even, alined stackon thesupport, any suitable guides orconfining devices may be employed. In thepresent instance we employ a vertically .disposed angular corner guide 61 which. is fastened at its foot tothe tableof the frame, and at its upper endembraces one corner'of the stack of wrappers as shown in Fig.9, the top of this corner guide 61 terminating in a lip 62 which overliesthe top of the wrapper and is inclined upward so as not to interfere with the removal of the individual wrappers from the stack. .To prevent more than one sheet of wrapper being taken from the stack at one time we preferably provide a.front clamping .finger63, the free angular end 63 of which engages the top of the stack of wrappers, as shown in Fig. 9. This clamping finger 63 is mounted upon a rod64l and is tensioned by means of the coil spring 64: so that the spring tends to normally throw the ends 63 of the finger into clamping position. hen the operator desires to replenishthe stack, the clamping finger 63 may be grasped and swung out of the way, by

swinging the rod 64:, because this rod 64 is socketed in a swinging sleeve '65, the upper end of which is formed with a pintle 66 journaled in the bracket lug 66 .on the corner guide 61,'while the lower end of such sleeve which is supported in the bracket lug 66" terminates in. an eccentric 65 to'which is connected .one :end of asliding rod 67 tensionedby the expansionspring 67 this rod sliding through small bracketJlugs 68 the rearmost of'these lugs 68 being carried by the corner plate 68 which is mounted upon the bed 13. As will be understood by reference to'Fig. 2,the1rod 64 in itsnormal positionwhenholding the clamping finger in engagement with the stack of leaves is maintained in such position by the spring tensioned rod 67. However, if it is desired to replenish the stack and this :rod 64:is swung'outward, the expansion spring 67 will be contracted until the eccentric 165' is swung over the .deadcenter, when the pull on the rod 64 maybe released and the swing having expanded, the rod withthe clamping finger will be held in its open position.

away fromthestack. To restorethe parts to clampingposition, it is only necessary to swing therod 6% toward the stack and over the dead center again and the actionof the spring 67 will throw the rod with the clamping finger into clamping position. At theuopposite side of thestack of wrappers there is located a vertical guide bar 69, the foot of which is fastened-to the bed B of the frame and the upper end .70of which lies against .and forms an alining'guide for stack terminates in a .shortlip 72 which slightly engages the. stack ofwrappers near the adjacent corner end. The bar 69 near its upper end is formed with a rib 7 3 which is centrally recessed .as..:at'7 l to receive the lower end of the rocking tongue 75, this tongue being mounted to .rock with the movement of the crank-rod 76 journaled in the rib .This crank rod is rocked through a link rod 77, the lower end of which is connected at? 8 with the rock arm 79 carriedby theroek shaft 80 journaled in the bracket 81 depending from the frame, this-shaft being ro'ckedjfrom thecam shaft 7 through the 'cam' 82,-.cam-lever Y83 and link 8 f which is connected to'the opposite end of the shaft 80.from that'which the :arm 79 connected. Thus with every revolution of the cam, at predetermined times, the tongue 75 will-be rocked to and from the side-of the stack, this tongue 75- carrying anangular wire linger 85 which will knock or strike against the side of the wrapper stack with the proper movement of the tongue 75 and will act. as a joggerto assist in keeping the sheets of the; stack in aline .ment. A leaf-spring 86 tends to throw the tongue'75 towardthe wrapper-stack and the tongue is movedaway from the stack by the cam 1 mechanismagainst" the Y action of this leaf spring at the time. each'top wrapper is being removed from the stack by the glue pads whiehforma part of the glue or adhesivefapplying mechanism.

Thus by the various guides or alining devices just described the sheets are maintained in proper stacked alinement and yet are so held as not to interfere with the selection and removal of individual sheets at proper times.

We will now proceed to briefly describe the gluing or adhesive applying devices and the functions performed by the same. The letter J indicates a glue tank in which works a wallower or glue supplying roll 87 which is mounted on the shaft 88 driven through the beveled gearing 89 and shaft 90, the latter shaft in turn having a pulley 91 driven by the belt 92 from the pulley 93 on the power shaft 1, so that through the train of power transmitting mechanism just described, the wallower roll 87 may be rotated in the bath of glue shown at K in Fig. 4, thereby insuring a constant supply of fresh glue to the surface of the roll 87. The same shaft which carries the glue roll 87 also carries a small glue supplying disk 87, and the shaft may be set or adjusted to properly adjust the glue roll 87 and disk 87 lengthwise of the tank a slight distance, by means of the screw rods 9% connected with the shaft bearing. Any suitable arrangement, however, may be employed for proper-1v positioning the glue roll and disk in the tank.

Referring to Figs. 4, 7 and 8, it will be seen that the carriage is formed with a bracket 95 which includes a cross head 96 having an opposite side thereof, a pair of sleeves 97 through which slide bars 98 having attached to their lower end glue pads 99 which lie relatively to each other at opposite sides of the carrier head containing the package as will be clearly understood by reference to Fig. 4;.

These bars 98 carrying the glue pads are longitudinally recessed or cut away as at 100, and these cut-away portions of the bars work through the slots 101 in the cross bar 102, the shank 103 of which carries at its rear end the block 101 adapted to vertically slide or reciprocate in the slot 105 formed in the frame of the carriage, as will be seen by reference to Fig. 7. The shank 103 carries the oppositely extending stud shafts 106. and at the end of each of these stud shafts there is mounted a rocking bar 107 the forward end of each of these bars extends into the recess 100 of the adjacent glue pad carrying bar 98, while the opposite or rear end of each of these bars 107 lies beneath the limiting bolt or stop 108. It will be noted by reference to Fig. 7, that the forward end 107 of each bar l07 lies between the shoulder at the upper end of the recessin the bar 99 and the rear edge portion of the cross bar 102 so that this bar 107 at its forward end will have but a limited rocking motion. The cross bar 102 is fast with the sleeve 109 sliding on the post 110, the foot of which post is set on the top of the carrier head of the package. This sliding sleeve 109 is formed with a head 111 from which projects the oppositely extending studs 112, these studs being connected with arms 113 extending rearwardlv of the machine and fulcrumcd on the shaft 11 1 mounted in the web brackets 115 of the sliding carriage. Integral with and extending rearward from the arms 113 is an arm 116 pivotally connected with a block 117 slidingly mounted in the groove 118 of a rocking slide 119, the latter being journale'd at its ends as at 120, as shown in Fig. 1. This slide 119 is rocked through the cam lever 121 connected at one end with the yoke arm 122 at the back of the slide, the opposite end of this cam lever terminating in the usual cam fork 123 carrying the cam roller 124 operated by the cam disk 125. Thus, as the slide 119 is rocked up and down from the cam shaft 7 through the connection just described, the sleeve 109 will be given a corresponding vertically re ciprocating movement on the post 110. It will be noted by reference to Figs. 3 and 7 that the block 101 at the end of the shank 103 has socketed therein the upper end of the stem 126 of the glue applying stencil 127, the head 128 of which is best shown in Fig. 9 and is adapted to apply a stripe of glue to the rear transverse edge of each top wrapper of the stack at predetermined times, and simultaneously with the application of glue to the side edges of a wrapper by the glue pads 99, as will be nnderstood by reference to Fig. 8. Now in the operation of the machine the carriage first travels to the left of the machine, considering Fig. 1, which brings the glue pads 99 and the head 128 of the glue stencil 127 over the glue tank and into contact with the glue wallower roll 87 and the glue supplying disk 87 respectively so that the two glue pads 99 receive a supply of glue from the roll 87 as they slide across the top of the latter and in like contact therewith as will be understood by reference to Figs. 3 and 41, while the glue stencil head 128 receives this glue from the glue disk 87. At this time it should be understood that the carriage with the glue pads and stencil is to one side, or to the left of the stack of wrappers and that such pads and stencil are in an elevated position, or in a plane higher than the stack of wrappers, as will be understood by reference to Fig. 7, the glue tank with its roller and disk being of course so adjusted as to give proper contact with the pads and stencil respectively when the latter are moved thereover to receive the glue. After the pads and stencil have been supplied with glue, the carriage starts its retractive movement or its travel toward the opposite side of the machine and when it reaches the position over the stack of wrappers, the downward movement of the sleeve 109 on the post 10 causes the shank 103 and its cross bar 102 to be lowered a short distance thus lowering pads 99 and stencil 128 simultaneously into contact with the top sheet of the stack. The bars 98 carrying the glue pads will be lowered because while sliding in the sleeve 97 they will travel with the head 102 due to the fact that each bar has connected thereto, at 130, a contraction spring 131, the lower end of'which is connected at 132 to the sleeve through which the bar slides, and consequently the tendency of the spring is to lower or pull the bar and-the glue pad downward. However, the end 107 ofthe rocking bar 107 project-- ing into the recess 100,- acting in conjunction with the pivoted latc'h133, will prevent the downward movement of the bar 98, independently of the cross head 102, except at the time hereinafter described, a leaf spring 13% normally pressing the latch 133 into locking position beneath the front edge of the cross head 102, as shown in Fig. 7 Therefore, with the depression of the sleeve 109, the glue pads 99 and the glue stencil 128 engage with the top sheet of the stack, and when the cross head 102 has reached the limit of its downward movement under the action of the sleeve 109, the rounded shoulder of the latch head 135 hits the pin 136 and the latch-inoves outward against the action of the leaf spring 13 asshown in Fig. 8, causing'the bar 98 to be pressed or'pulled sharply downward a short distance by its spring 131 therebv pressing the pad 99 firmly into contact with the top sheet of paper, so that when the pad is again elevated the topsheet will be lifted along by it. Of course at the same time the glue stencil has applied a stripe of glue to the rear'transverse edge portion of the sheet. After thus gluing'and'engaging the top wrapper of the stack,the glue pads are lifted with such wrapper because the slide 119'st'arts to rock in theopposite direction under the-action of its operating cam, the carriage continuingits-travel'of'course and the result is that'the sleeve 109 will be-moved upward on the post 110 carrying'with-it the crosshead 102 and of r'a'iursev the shank 103 with the. rockingarm 107'. When the rear end of the arm 107 strikes against the bolt shank or stop 108', its forward end 107 will engage be n'eath the adjacent shoulder of the bar 98 and liftthe b'ar'bodily so as to permit the latch: l33ito dropback into latching position shown: in Fig. 7", tlmsholclingthe glue pad- 991 in its normal elevated position, and with the Wrapper sheet carried thereby and lying beneath'the box in the carrier head.

The continued movement of the carriage as at 142 on the top of the wall 0 of the frame and is rocked up and downby a cam lever 143 actuated from the cam 144 on the shaft 7 When the free end 141 of this lever 1 11 isrnoved down against the roller 139' at the upper end of the stem 139 it depresses this stem against the action of the spring; 1 16, and the plunger ll0'striking the package, pushes the same out from the carrier head past the plates 36, which are forced.

open to permit the passage ofthe package and the latter is forced into themouth of the forming well, carrying with it the wrapper sheet so that the latter is folded about the.

bottom and two opposite sidesofthe package by the walls of the well, as shown in Fig. 11.

By referenceto Figs. t and 6, it will be seen that the traveling carriage has rigid therewith a laterally extending bracket 147 which extends in the present instance to the right side ,of the carrier head in which the package is transported, and that sliding in the vertical section 1 18 of this bracket is a stem 1 19 tensioned by a spring 150 and carrying at its lower end a plunger plate 151 which lies beneath the flanged folding head 152 tensioned by the spring 153 and car ried by its sleeve 1st through which the stem 149 passes.- At the time the package is positioned as shown in Fig. 11, the stem- 119 and the partsoperat'ed thereby lie to the right side of the forming well or in operat ive position; New asthe carriage with thecarrier head starts its retraetive motion or toward the left of the machine after delivering'thepackage and wrapper to the form ing'well, as shown in Fig; 11',two oppositely acting'foldin g plates 155' mounted on top of and projecting beyond tuck in fingers 156 are brought into operation to fold over the top flaps of the wrapper f, as indicated in Fig. 12'and then after these flaps have been folded down the tuckin fingers 156, of which there arefour, fold in the corner laps of the package, as shown in Fig. 13; Of

course the folding plates155and the tuck-iii j fingers 156 on which the plates arelnounted, areoperatedin proper timed relation, or di rectly afterthe plunger of the carrier head has forced the package and the wrapper into the forming'well, as'shown in Fig. 11. The tuck-in fingers 156-carrying these plates 155 areoperatec'l through suitable links 157 ac-- tuated from cam rods 158 which in turn are operated by the cams 159 on the shaft 7, and is to be understood that these tuck-in fingers may be of any well known'form. After the tucking in of the corner laps, the return movement of the carriage brings the stem 149 beneath the presser arm 141, and the lat ter being again depressed, strikes the upper end of the stem and causes the flanges 152 of the folding head 152 to fold down the side flaps f of the wrapper, as shown in Fig. 14. At this time the carrier head is re ceiving another box, and the carriage continuing its travel toward the left, the glue pads receive another supply of glue. Then as the carriage starts toward the right of Fig. 1 on another trip, and with another box,

as it reaches its position to take the wrapper, the stem 149 is of course again brought beneath the arm 141, and the latter being (Iepressed this time, forces the stem 149 downward, and this movement, shifts the plunger plate 151 from the position shown in full lines in Fig. 4, to that shown in dotted lines in said figure, thus pushing the nearly completely wrapped package of Fig. 14 down into the chute and the rollers 160 at opposite sides of the chute, contacting with the bottom side flaps f will fold the latter up over the laps f and the package will be sealed as shown in Fig. 15, the adhesive or glue stripes of cours causing the adherence or sealing of the various flaps of the wrapper.

The operation of the machine is successive and continuous, the various steps of feedin folding and the like taking place in proper sequence and in proper timed relation. The tab f of the package may be provided on one of the top flaps to permit the easy and ready opening of the package.
