6 paper.

Cellophane paper, because of its clear transparent character and comparative toughness, is a very desirable wrap ing material, and has now been extensive y used in hand wrapping.-' Its transparency makes possible the full display of-articles or materials enclosed therein in such manner that the color and other physical characteristics of the enclosed articles or materials are in no way concealed or undesirably modified in appearance. Owing to the fact, however, that cellophane paper is very sensitive to temperature and humidity changes, the same is subject to a considerable degree of expansion and contraction,'and consequently difficulty has been experienced in handling the the same by automatic machine wrapping means and methods. For example, if the machine produced wrapping thereof is too tight or close fitting relative to the articles or materials enclosed therein, and shrinkage occurs, the wrapping is likely to split, break open sealed or gluedfolds, or be otherwise disrupted; and, on the other hand, if the wrapping thereof is too loose, and ex ansion occurs, the wrapping is likely to buc 1e and wrinkle to the detriment of the appearance of the wrapped articles or materials.

' This invention, therefore, has for its principal object to provide an automatic wrapping machine especially adapted to manipulate cellophane paper in the production of enclosing wrappers about articles and materials of various kinds; and to this end .the machine includes means adapted to feed such cellophane paper from a supply thereof, and means to fold the same about the articles or materials to be wrapped therein, all in such manner as to obtain a good appearance and neat fitting of the cellophane paper wrapper about the articles or materials enclosed thereby, wliile at the same time leaving sufiicient looseness, particularly at the points where end folds are glued together or sealed, that contraction and expansion of the cellophane paper will not split, break open sealed or glued folds, or otherwise disrupt or detrimentally affect either the integrity orappearance of the wrapper.

Another object of this invention is to provide a relatively simple, eflicient and speedy machine calculated to produce desired wrappings in a rapid and uniform manner; and, furthermore, this invention provides a novel means for making sealed wrapperend folds.

Another object is to provide means cooperative with the wrapplng devices for first applying to the articles or materials to be wrapped in cellophane paper, a label band, so that the same will be enclosed by the subsequently applied cello hane wrapper, through which it will be plainly visible, while yet protected by the wrapper against soiling or mutilation.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Figs. 1 and 1, taken together, show a side elevation of a wrapping machine made according to this invention; Fig. 2 is a top plan view of that portion of the machine shown in Fig. 1 with certain parts in section; and Fig. 3 is a longitudinal section of parts of the machine, to illustrate the means for propelling the articles or materials and wrappers therefor relative to the wrapper folding mechanisms.

Figs. 4 to 7 inclusive. are fragmentary diagrammatic sectional views taken on line 4-4 in Fig. 2, and respectively illustrating various stages in the operation of the end fold tucking rolls of the mechanism.

Figs. 8 to 11 inclusive are fragmentary diagrammatic sectional views, respectively ployed in the above. described to illustrate the operation of applying adhesive to the end folds of the wrapper.

Fig. 13 is a fragmentary diagrammatic sectional view, taken on line 1313 in Fig. 2 to illustrate the means for upturning the end folds of the wrapper.

Fig. 14 is a fragmentary sectional view, taken on line 14-14 in Fig. 2, to illustrate the means for infolding and laying the wrapper end folds in sealed relation to the main body of the wrapper.

Figs. 15 and 16 are enlarged fragmentary sectional views to illustrate the operations of the end-fold manipulating and laying devices.

Similar characters of reference are emviews, to indicate corresponding parts.

To illustrate the construction and operation of the wrapping machine of this invention, the same is shown as designed t) wrap flat rectangular articles, such e. g. as cards of tape, blnding or the like. The tape or binding is wound about a rectangular cardboard core. In handling such-class of work it is desirable. to first dispose about the same a printed label band, thereupon applying over and about the label band and card of tape an enclosing wrapper of cellophane paper.

Referring to the drawings, the reference character 20 indicates a bed-plate upon which wrapping mechanism is mounted. This bedplate, in practice is usually supported on suitable standards or leg frames (not shown).

J ournaled in a edestal bearing 21, which is supported on said bed-plate 20, is the shaft 22 of a carrier head 23. Said carrier-head 23 is driven by any suitable power transmission means (not shown) which is adapted to produce intermittent rotation thereof in the direction of the arrow :1: in Fig. 1. Said carrier head 23 is provided, in radial extension therefrom, with a plurality of receiving pockets 24, each formed by parallel wall portions, one of which is provided with a spring cushioned yieldable face plate 25.

Arranged at the forward side of said carrier head 23 in horizontal plane, and extending toward the same in alignment with an opposed receiving pocket 24 thereof as the latter is disposed during the periods of rest of said carrier head, is a feed table 26. Co- 0 erative with said feed table 26 is a mova le conveyer 27, preferably of the endless chain type, and having spaced apart push fingers 28 to engage the articles to be wraipped so as to move thesame along said fee table 26 successively toward the carrier head 23. Bearing standards 29 are fixed on said bed-plate in which is journaled ashaft 30 carrying the sprockets 31 of the chain conve er 27. 1

ositioned in advance of the carrier head 23 is a label band supply holder and feeding means, the latter being adapted to deliver a label band intermediate a carrier head receiving pocket 24 and an articleabout to be entered therein, in carrying out the operations of applying said label band to said article.

The label band supply holder comprises a magazine 32 supported by a suitable framework 33' connected with the upper ends of said bearing standards 29, and adapted to hold a stack or pile of label bands. The magazine 32 possesses a bottom plate 34, and further includes, atthe bottom of its rearward end portion, one or more brackets 35 to which are affixed upwardly andrearwardly inclined and directed retaining spurs 36, preferably in the form of sharp needle-like points. Intermediate the spurs 36 and plate 34, thebottom of the magazine is open. J ournaled for disposition beneath this opening at the bottom of the magazine is a feed roller 37, provided along a portion of its periphery with a circumferentially ofi-set frictional gripping section 38, preferably made of soft I rubber or other frictional material, the same being adapted, at properly timed moments during rotation of said roller, to engage a bottom-most label band and feed the same forwardly and outwardly from the magazine. Aligned with and extendim from the bot-,

tom plate 34, is a downwardly curved guideway 39, adapted to lead the discharged label band downwardly between a series of grippingand feedin rollers 40, whereby the label and is vertical y suspended between a car.- rier head pocket 24 and an article to be entered therein. The gripping and feeding rollers 40 are driven by gearing 41 from the feed roller 37, said gearing including a segmental'gear 42, whereby timed intermittent actuation of the 40 is attained.

gripping and feeding rollers Aligned beneath the depending endof the guideway 39 is means to apply adhesive to an end of a delivered label band prior to its entrance with the article, to which it is to be applied, into the carrier head pocket 24. This means comprises a vertical backing plate 43 with cooperating guides-44 to posi tion the lower end of the label hand against said backing plate. Adjacent to said backing plate 43 is a glue-pot 45 in which runs a glue pick-up roller 46. Arranged to rotate intermediate said pick-up roller 46 and backing plate 43 is dauber arm 47, which, in its'rotation, contacts with the glue carried on the surface of said pick-up roller,and then contacts with the depending end of the label band so as to apply a desired quantity of glue thereto. Said dauber arm 47 may driven, in timed relation to the delivery of the label bands to the backing plate 43, by any suitable transmission means (not shown).

. Means are provided for inserting an article and label band into the pockets of the carrier head 23 at one side thereof and ejectthe feed table 26 and beyond opposite sides.

of the carrier head 23. Also fixed on said shaft 53 is a lever arm 55, having a laterally rojecting stud 56. Mounted in a guide stan ard 57 is a vertically reciprocable member 58 provided at its upper end with a longitudinally slotted head 59, within the slot 60 of which is engaged the stud 56 of said lever arm 55. )Vhen said member 58 is raised to its upward limit of movement (as shown in Fig. 1), the lever arm 55 will be up-swung to turn the shaft 53 so as to swing down the delivery fingers 54 into article engaging position. The feed conveyer 27 having delivered an article in position adjacent to a pocket 24 of the carrier head 23, the member 58 is timed to rise, thereupon swinging downward the delivery fingers 54 behind said article. W'hile the parts are in this position, a suitable timed transmission means (not shown) operates to cause a forward movement of said reciprocable plates 48, thus causing said delivery fingers 54 to engage the article and push the same forwardly and into the waiting pocket 24 of the carrier head 23. As the article is thus moved into the pocket 24, the same engages the delivered label band so that the latter is doubledabout the article as entered in said pocket, with a glue carrying end of the label band projecting from the circumference of the carrier head.

After an article'and label band hasbeen entered in the carrier head 23, the latter by intermittent rotation in the direction of the arrow at in Fig. 1, carries the article and label band into alignment with a stationary folder means (to be subsequently described) which is located at the opposite side of said carrier head. During the rotative movement of said carrier head 23, the delivery fingers 54 are raised and retracted to normal initial position. This is accomplished by the lowering of the slotted head 59 by downward retraction of the vertically reclprocable member 58 prior to the retractive stroke of the reciprocable plates 48. This lowering of said slotted head 59 serves to swing down the lever arm 55 to turn the shaft 53 so as to swing up the delivery fingers 54 out of the path of movement of said articles, so that on rearward retraction of the reciprocable plates 48 said fingers will pass over the succeeding article which is moved forward by the conveyer 27 ready to be inserted with the next delivered labelband into the succeeding pocket 24 of the carrier head 23. These operations being repeated in time with the step by step movements of said carrier head.

The means for ejecting an article and label band from the carrier-head 23 is also carried by the reciprocable plates 48, and comprises ejector fingers 61 pivotally connected with thelatter, the samebeing lowered to article engaging position and raised out of the path of movement of the articles by lever arms 62 which are interconnected by links 63 with lever arms 64 fixed to said shaft 53, whereby said ejector fingers 61 operate in time with said delivery fingers ,54 while the carrier head 23 is at rest.

The stationary folder means above mentioned comprises a pair of vertically spaced folder plates 65 and 66, suitably fixed and supportedby astandard or supporting post 67, so as to be aligned with a rest position of the pockets 24 of the carrier head 23. While an article and label band are being delivered into a carrier-head pocket 24 at one side of the carrier head, an article and label band are ejected by the ejector fingers 61 from the opposite side of the carrier head 23, and delivered between the folder plates 6566. As the article and label band enters between said folder plates 6566, the projecting glue bearing end of the label band will be engaged and turned over upon the article, so as to comlete the folding of the label band about the atter, and so as to press said glue bearing end into adhering engagement with the first folded end of the label band.

J ournaled in a pedestal bearing 68, which is mounted on said bedplate 20, is the shaft 68 of a second carrier head 69. Said carrier head 69 is driven by any suitable power transmission means (not shown), which is adapted to produce intermittent rotation thereof in the direction of the arrow y in Fig. 1, and in time with the movements of the carrier head 23. Said carrier head 69 isalso provided, in radial extension therefrom, with a plurality of receiving pockets 70, each formed by parallel wall portions, one of which is provided with a spring cushioned yieldable face plate 71.

Cooperative with said carrier head 69 is means for feeding cellophane paper to form wrappers for the articles operated on. This paper feed means comprises a supporting frame-work 72 carried by extensions of the pedestal bearings 21 and 67. Said framework 72 includes an up-standing post 73 upon which is fixed a spindle 74 for rotatably mounting a roll of cellophane paper 75. R0 tatably supported by said frame-work 7 2 are a pair of opposed paper feed rolls 76 and 77, the latter being spring pressed toward the former so as to grip the paper therebetween. Means are provided for causing timed rotation of-said feed rolls 76-77, whereby the aper is drawn down 0d the supply roll.

his means comprises a stud shaft 78 :on which is rotatably mounted a drive gear 79 which meshes with a gear 80 on the shaft of the feed roll 76 so as to drive the latter. Said feed rolls 76 and 77 are geared together for operative rotation, respectively in opposite directions, by gears 81 and 82. Pivotally mounted on the stud shaft 78 is an oscillatable arm 83 having pawls 84-85 to engage a ratchet wheel 86 which drives the drive gear 79. Properly, timed oscillation of the arm 83 is produced by means of a suitably driven cam 87 which operatively engages the roller stud 88 carried by a pivoted lever arm 89, the free end of which is connected'with said oscillatable' arm 83 by a link 90.

Cooperating with "and'forming a part of the ,paper feed mechanism is a vertically reciprocable paper ipping means which engages with the si e margins at the free end of paper stripes the same is fed downward by the feed rolls 76-77, so as to hold the cellophane paper smoothly spread in front of a pocket of thecarrier head 69, and free from curls or wrinkles, ready to be engaged by and entered with an article into said pocket. Such means is essential for assurance of proper delivery and disposition of the cellophane paper, for the reason that the latter has a strong tendency to curl, especially in humid or damp weather; This paper gripping means comprises vertically reciprocable members 91 at each side of the path of paper movement, the reciprocations of which may be produced by any suitable form of actuating means (not shown) adapted to cause timed cooperation with the paper feed rolls and article delivery means functioning to'deliver the articles with the paper into the pockets of the carrier head 69. Connected with each member 91 is a fixed gripping jaw 92 and pivoted gripping jaw 93, the latter being biased to open or separated relation to the former. Journaled in each member 91 is rock-shaft- 94 having on its inwardly projecting end an eccentric cam 95, adapted at proper times to thrust said pivoted gripping jaw 93 into paper gripping relation to said fixed jaw 92. Fixed on the Outer end of said rock-shaft 94 is a lever arm 96, having, adjacent to its free end, a lateral stud 97. Secured to said supporting post 67 is a stop-lug 98, which engages and up-turns said lever arm 96 to in turn move the cam 95 to jaw opening or releasing position, when the members 91 reach the limit of their downward movement. Pivoted on the outer side of each member 91 is a trigger-finger 99. one end of which bears on the stud 97 of the lever arm 96. Provided at the opposite end of said trigger-finger 99 is a chamfered nosing 100. Fixed on the upper end of said supporting post 67 is a bracket extension 101- which carries a spring biased yieldable stop-dog 102, the same being disposed in the path of movement of the nosing 100 of said trigger-finger 99. 1

ooperating with the paper feed mechanism is a severing'm'eans adapted to sever from the'downwardlyfed length of paper a portion thereof suflicient to provide a wrapper sheet. This severing means comprises a stationary shear blade 103 secured to the frame-work 72 andv disposed beneath the feed rolls 7 6-77'. Pivotally connected with said stationary shear blade 103 is a movable shear blade 104. The means for producing properly timed operation of said movable shear blade 104 comprises a cam 105 which serves to oscillate a lever 106, the latter having a roller stud 107 to engage in the race of said cam 105. Slidably mounted in connection with the frame-work 72 is reciprocable slide-piece 108, the rearward end of which is connected with the free end of said lever 106 by a link 109. The forward end of said slide-piece 108 is pivotally connected to the free end of said movable shear blade 104.

In the operation of the machine, prior to the delivery of an article to be wrapped into a pocket 70- of the carrier head 69, the paper feed mechanism is timed to function in the following manner. Through the described actuating mechanism, the feed rolls 76-77 are rotated so as to draw the cellophane paper off the supply roll and feed the same downward through the open severing means and in front of the carrier head 69. As the feed rolls 76-77 start the paper downward, the actuating means serving the gripping devices moves the members 91 upward toward the free end of the downwardly fed paper. As'the members 91 rise, the nosings 100 of the trigger-fingers 99 are carried upwardly past the yieldable stop-dogs 102., the latter yielding to this movement thereof. The gripping jaws 92 and 93 being in open relation, will receive the end of the paper therebetween as it passes the shear blades, whereupon the actuating means serving the gripping devices will reverse the movement of the members 91, causing the same to move downward in time with the continued downward feeding of the paper by the feed rolls 76-77. As this downward movement is initiated, the nosings 100 of the trigger-fingers 99 are carried downwardly into operative engagement with the stop-dogs 102, whereby the trigger-fingers are swung downward, to

in turn engage and swing downward the lemoved, While at the same time the paper is held smoothly spread across the forward side of the carrier head 69 so as to be engaged by an article and entered therewith in a pocket 70 of the latter. As the limit of downward feeding movement of the paper is" approached, the lever arms 96 engage the fixed stop-lugs 98, which, as the downward movement of the members 91 is completed, serve to turn upwardly the lever arms 96 to release the cams 95, and thus permit opening movement of the movable gripping jaws 93. while at the same time re-setting the trigger-fingers 99 to normal initial positions. As this occurs the severing means is timed to operate whereby a down-drawn length of paper is severed from the supply, ready to form a wrapper. I Substantially simultaneously with the release of the gripping jaws 9293 and the severing of the paper, the means for delivering the waiting article into an opposed pocket 70 of the carrier head 69 functions so as to immediately engage the paper and partially fold the same about the article during its movement into'said pocket. The article delivery means comprises a. second set of delivery fingers 110 pivotally connccted with the forward ends of the reciprocable plates 48, the same being so arranged as to be raised to article engaging position and lowered out of'the path of movement of the articles by lever arms 111 connected by links 112 to lever extensions 113 forming a part of said lever arms 62, all whereby said delivery fingers 110 operate in time with the operations of the heretofore described delivery fingers 54 and ejector fingers 61, as will be understood from an inspection of Fig. 1 of the drawings.

When an article and wrapper is entered in a pocket of the carrier head 69, the latter is intermittently rotated in the direction of the arrow y in Fig. 1 to carry the same around to folder devices into which the same is to be delivered from the carrier head. Located at a stage in the intermittent rotation of the carrier head, in advance of the position of the folder devices into which the article and wrapper is to be delivered when discharged from the carrier head 69, is means for applying adhesive to the wrapper portion which projects from the pocket of the carrier head. This means comprises a supporting platform 114 carried by extensions 115 of the framework 72. Mounted on said platform 114 is a glue reservoir 116, in which is arranged a rotatable glue pick-up roller 117. Formed in connection with the end of said glue .reservoir, which is adjacent to the carrier head 69. is a wrapper backing or supporting shelf 118. Means are provided for engaging and laying back' the projecting portion of the wrapper upon the backing or supporting shelf 118 during a period of rest of the carrier head, whereby glue may be applied to such portion of the wrapper. This latter means comprises ,rotatable'spreader members 119 adjacent to each' side of the carrier head,

and adapted, when rotated, to engage the side ends of spindles '120 'journaled in bearing brackets 121 mounted on the frame-work 72. A transverse drive shaft 122 is journaled in said frame-work 72, and is adapted to be driven in properly timed relation to the movements of the carrier head 69 by an suitable transmission means (not shown) aid spindles 120 are driven from said shaft. 122 by intermeshing bevel gears 123124, as shown in Fig. 1. The glue pick-up roller 117 is driven from said shaft 122 by a chain and sprocket transmission 125, or in any other suitablemanner. Connected'with said gluereservoir 116 are bearing arms 126 which project over said backing or supporting shelf 118. J ournaled in and between said bearing arms 126 is a shaft 127 on which is fixed a dauber arm 128; the shaft 127 being driven from said pick-up roller 117 by intermediate gearing. 129. The rotation of the dauber arm 128 is timed to engage the surface of said pick-up roller 117 to receive an application of glue therefrom, and then in its travel to contact with the wrapper portion, which has been previously spread on. said backing or ed, so as to transfer and apply thereto an application of said glue.

Opposed to the carrier head 69 so as to extend forwardly and away therefrom, and aligned with the pockets 70, when the latter are disposed in position at which articles and their wrappers are discharged therefrom, is a suitably runway 130, the same havlng longitudinal slots 131 therein, to accommodate the movements of article ropelling means adapted to propel the artic es step by step along saidrunway and in operative rela-- tion to various wrapper fold forming devices which border said runway.

The article propelling means comprises propeller bars 132 having up-standing pushfingers 133 spaced Ion itndinally apart from end to end thereof. aid propeller bars 132 are actuated in a longitudinally and vertically reciprocable path of movement indicated by the diagram 2 in Fig. 3. To this end said propeller bars are slidably carried on guide blocks 134 which are fixed on vertically reciprocable bars 135 movable in guide brackets 136. Pivotally connected with said guide brackets are bell-crank levers 137, one arm each of the bell-crank levers are respectively connected with the vertically reciprocable bars 135, and the other arms thereof are interconnected by a link 138, so that the bellsupportingshelf 118 in the manner above de 'scri crank levers work together. The means for actuating the bell-crank levers to cause timed rise and fall of the propeller bars 132, to carry the same into and out of the path of movement of the articles and their wrappers, as moved along said runway 130', comprises a suitably driven rotatable cam 139 and a reciproeablecross-head 140 having a roller stud 141 operatively engaged in the race of said cam 139.. Movable with one of said bell-crank levers 137 is a lever arm 142, which is connected with one end of the crosshead 140 by a connecting rod 143, The opposite end of the cross-head 140 is coupled through connecting rod 144 with a lever arm 145 adapted to oscillate lever members 146 serving to produce timed vertical reciprocation of the member 58 previously described. The longitudinal reciprocation of said propeller bars 132 is caused by suitably actuated oscillatable levers 147, the upper ends of which are operatively coupled with said propeller bars by links 148.

Positioned at the inner end of the runway 130, which is opposed to a pocket of the carrier-head 69 broughtto rest in alignment with said runway, and spaced above said runway, is a folder plate 149. supported by rods 150 depending from said platform 114. The under side of said folder plate 149 is provided with a spring cushioned presser plate 151. Secured to the inner margin of said folder plate 149 is a folder lip 152.

As the carrier head 69 rotates to carry an article and wrapper from the glue application station to the point of discharge to the folder devices, the projecting portion of the wrapper will engage and be up=turned by the folder lip 152, so that as the carrier head 69 comes to rest the article and wrapper is disposed so that, when discharged from the carrier-head pocket 70 upon the runway 130 and beneath the folder'plate 149, the up-turned projecting portion of the wrapper will be turned'downward and rearwardly over the other folded end of the wrapper, and the glue application applied to the former will cause the same to adhere to the latter, thus completing the longitudinal folding of the wrapper about the article. The discharge of the article and its wrapper from the carrier-head 69 to the runway'and beneath the folder plate 149. is effected by a forward movement of the propeller bars 132, the readward push-fingers 133 of which have been carried beneath and then up behind the end portions of the article when the propeller bars were retracted. At

the end of the forward stroke of. the. propeller bars 132, the article comes to rest in position to be engaged by end; fold tucking means mounted at the sides ofthe; runway 130. which means is timed to be operative while the propeller bars 132 are being retracted for a succeeding article propelling stroke.

Said end fold tucking means comprises rotatable tuekingrolls. Each said tucking roll is journaled in bearings153 mounted on base-plate structures 154, which are in turn supported on standards 1'55 rising from the bed-plate 20 and an extension 20' thereof. Journaled in and extending longitudinally between standards 155. at one side of the machine, is a drive shaft 156, which is driven by suitable transmission means from the power source of the machine. In like manner there is journaled in and extending longitudinally between standards 155, at the other side of the machine, acorresponding shaft 157, driven from said shaft 156by chain and sprocket transmission 158 (see Fig. 14). J ournaled in bearings 159 fixed on the baseplate structure 154, at each side of the machine, are counter shafts 160, which are respectively driven from the

respective shafts

156 and 157, either by chain and sprocket transmission 161 (as shown in Fig.2 at one side of the machine), or by gearing 162 (as shown in Fig. 2 at the other side of the machine). Said tucking rolls are driven from counter shafts 160 through intermediate gearing 163.

Each tucking roll 164 is provided in its circumferential face with a sector-shaped open portion 165 bounded on its leading side, throughout the length of the roll, by a radial face 166 slightly chamfered endwise toward the carrier head 69. The tucking rolls are so. positioned that their longitudinal axes are substantially in the plane of the. article supporting surface of the runway 130. to which the rolls are opposed; As the articles. with wrappers folded and secured longitudinally about the same, are brought to theiri point of rest in alignment with the tucking rolls, the latter will be positioned so that the projecting end portions of the wrapper will ride over the radial faces 166, and will thus extend into the open portions 165 of said rolls.

member, and gradually reducing in depth out- I wardly until merging with the circumferential surface of the main body of the roll. The body of the roll beyond the radial .face 166 is cut back circumfenentially for a short distance to provide a-clearance space 170.

While an article and its wrapper is at rest on the runway 130, and the ends of the wrappers entered in the open portions 165 of the tucking rolls (as shown in Fig. 4), rotation of the rolls will operate to tuck and laterally fold the projecting end portions of the wrap- 5 per to provide the latter with end closing flaps. The operation of the tucking rolls is illustrated in Figs. 4 to 7 inclusive of the drawings. By its rotation the tucker member 167 of a roll is carried toward the projecting wrapper end, so as to engage the upper ply of the wrapper, wherebyrthe same is folded down over the end of the article, and at the same time into coextensive contact with the under ply, thus also forming upstanding tuck folds at the sides of the thus formed closing flap (see Fig. 5). Continued rotation of the roll turns down the closing flap over the margin of an extension 171 of helically slotted guide plate 172, which is mounted contiguous to the inner edge of runway plate 130. As the closing flap is thus turned down, the up standing tuck-folds tend to swing inward thereover, clearance for such movement thereof being'provided by the grooves 168 in the sides of said tucker member 167, so that as the roll continues to turn these tuck-folds will be led into the tuck turning grooves 169, which compel the tuckfolds to fold down and inwardly over the closing flap (see Fig. 6). On further rotation of the roll its smooth circumferential surface is moved against the in turned tuc folds so as to crease and iron the same down in desired position (see Fig. 7).

By the time the clearance space 170 of the roll is brought in opposition to the down turned and folded closing flap, the propeller bars 132, which in the meantime have been dropped below the runway 130 and retracted ready for another article propelling stroke, are again raised to engage certain of their push fingers 133 behind the article, and, when thus positioned, move forward to push the article and wrapper forwardly along the runway 130 to the next point ofrest. As the article and wrapper is so moved, the down turned closing flap, at each end of the article. is moved through a helical slot 173 of the guide plate 172, whereby the closing fia p is turned upwardly to horizontal position, so that the same comes to rest over a resilient or spring cushioned backing plate 174 adapted to support the closing flap forapplication of adhesive thereto. In order to retain the wrapper in-folded against the article. at the point thereof from which the closing flap springs. a thin vertical keeper plate 175 is fixed in place. with its lower margin spaced from the level of the runway 130 a sufficient distance to permit the closing flap to move thereunder. The above described operations willgbe best understood from an inspection of 8 to 11 inclusive of the drawings.

Located on each side of the runway 130. at points aligned ,with va point of rest of the articles and wrappers beyond the tucking rolls, are means for applying adhesive or glue to the closing flaps prior to the operations of folding the latter inwardly and over the body of the wrapper. Each such means comprises a glue reservoir 176 having a r0- tatable pick-up roller 177. the same being driven by suitable clutch mechanism from an adjacent counter-shaft 160. Mounted in bearings 178 is a rock-shaft 179 on which is fixed an oscillatable dauber arm 180. At proper moments, through suitable transmission means, the dauber arm 180 is swung back to engage "the pick-up roller 17 7 to take up therefrom an application of glue, thereupon being swung forward to engage a closing flap of wrapper to transfer the glue application thereto (see Fig. 12). The yieldable backing plates 174 so support the closing flaps as to assure equal depositing pressure of the dauber arms relative thereto.

By. succeeding operations of the propeller bars 132. the article and wrapper is carried further along the runway 130,-so as to engage in passing tip-turning blocks 181, having upwardly and forwardly inclined top surfaces, and perpendicular inner side faces. each having at its foot a curved bottom marginal element 182. As the closing flaps engage the blocks 181 the same will be turned upwardly across the ends of the article, as shown in Fig. 13. The rounded or curved element 182 allows the juncture of the closing flap and main body of the wrapper'to assume a somewhat outwardly curved and not too tightly creased fold, whereby a little looseness of the wrapper at such points is provided for, so that it will readily compensate itself under stresses of contraction and expansion.

Bv' further succeeding operations of the propeller bars 132, the article and wrapper, with the closing flaps up-turned, as described, is conveyed to. and brought to rest in alignment with fold turning devices which border the sides of the runway 130. These fold turning devices each comprise a swingable shutter 183 pivotally supported by fulcrum blocks 184. This shutter 183, when actuated, is adapted to swing down from vertical position to horizontal position overlapping an end of the article. thereby turning over the up-stapding closing flap of the wrapper downwardly upon the body of the wrapper, the glue bearing face of the closing flap being thereby pressed into adhering relation to the body of the wrapper so as to complete the folding and securing of the latter about the article and its encircling. label band. The means for producing properly timed oscillation of the shutter 183 comprises pivoted levers 185, having open yoke portions 186 in which are operatively engaged rotatable cams 187 respectively driven by the

shafts

156 and 157. The upper ends of contained in the above description. or shown.

said levers 185 are operatively connected with said shutters 183 by links 188.

' Cooperative with said shutters 183 are vertically movable spring cushioned shaping members 189 having curved lips 190 to overhang the ends of thearticles and their wrappers. These shaping members 189 lie underneath the shutters 183 so as to be depressed by the downward swinging movement of the same, whereby the lips 190 are caused to engage and round over the fold of the closing flaps of the wrapper, as the former is over turned upon the body of the latter by the operation of the shutters 183; thus furtherassuring a little looseness of the wrapper at such points so as to readily compensate for contraction and expansion thereof (see Figs. 15 and 16).

After the folding of the enveloping wrappers of the articles has been completed by the operation of the shutters 183 and shaping members 189, further operation of the propellerbars 132 will eject the completely wrapped articles from the machine.

In order to hold the articles andtheir wrappers against displacement, during their movement through the runway 130 and while subject to the operations of the wrapper end folding devices above described, a top plate 191 is provided to overlie the articles moving through the runway. This top plate is hingedly securedby carrier arms 192 to fulcrum posts 193, so that the same may be swung open, when desired, to give access to v the articles moving through the runway.

It will be obvious fromlthe above description that the machine of the instant invention provides a means peculiarly adapted for wrapping articles in cellophane paper,

the wrapping operations'being progressively carried out during the step by step movement of the articles through the machine in continuing succession, whereby a comparatively high speed automatic operation 15 attained with resultant large capacity of output durin a given period of time.

It will could be made in the above described constructions and many apparentlyvwidely different embodiments of this invention could be made without departing from the scope thereof as defined in the appended claims, consequently it is intended that, all matter in the accompanying drawings, shall be interpreted as illustrative and not inalimiting sense.
