17 Claims.

This :invention relates to a stringing apparatus for booklets or covers which enclose cigarette papers and the like and more especially to means for eflectively and rapidly affixing a binder String to one edge thereof which can be used to hold the booklet in closed position.

In order to properly bind cigarette papers in booklet form, it is necessary to 'adhesively or otherwise secure one edge of all of the papers to a suitable cover. This cover is preferably crimped in such a manner that it can be wrapped entirely around the papers with its ends overlapping. When the cover has been thus folded, it is very essential that means be provided for holding the same in position to prevent the papers therein from becoming exposed while packing and shipping or while in the users pockets.

2 One of the simplest securing means comprises a string, one end of which is secured to an overlapping end of the cover. The free end of this string is adapted to encircle the folded booklet and then be drawn between an intermediate per- 25 tion' of the string and the cover "where it will be frictionally held in position to hold the booklet closed.

It is an object of this invent-ion to provide an apparatus which will aflix these binder strings 30 in rapid succession to one edge of a continuous cover. Subsequent to this operation, the continuous cover is severed intermediate the strings so that individual covers will be formed, each cover having a string attached to one 'end 35. thereof.

It a further object of this invention to provide an apparatus for rapidly attaching one end of a string to a cover for cigarette papers, com prising means for advancing at a constant rate,

40 a continuous cover through the machine, and

means for intermittently feeding one end of a string together with an affixing stamp to the upper surface of the cover so that the stamp can adhesively secure one end of the string to the cover. After the ends of the string are affixed it is then severed so as to provide the desired length, after which the string is fed to and attached to the continuous cover, at another point in the same manner. 7 v

50 It is a further object of this invention to provide an apparatus of the class described having an improved means for positioning the leading .end of the string on top of the cover so that the afiixing stamp can be effectively pressed 55 t-hereover.

Referring more specifically to the drawings, the numeral ||l denotes a cover for a cigarette booklet having fold or crease lines I I, 2, l4, and I5 thereby forming sections IS, IT, l8, l9 and 2B (Figure 3). By the apparatus hereinafter to be described, one end of a string 2|.is positioned above the upper side of section 20 after which a stamp 22 is affixed thereover to secure the same to the cover. After this operation has been performed, a bundle of cigarette leaves 23 are adhesively secured to the section I! which is disposed between the crease lines II and I2 (Figure 2). Then the booklet may be folded to the position shown in Figure 1 and the string 2| wrapped therearound with its free end drawn between the intermediate portion of the string and the exterior of the cover where it is 'frictionally held in position. Figure 2 shows the booklet in an open position with the cigarette leaves therein, whereas Figure 1 shows the booklet completely closed, at which time it will be noted that the sections l6 and 20 overlap each other and are held in this overlapped position by means of the binder string which is affixed to the overlapped section 20.

In the manufacture of the covers ID, a connuous sheet of stock material 26 is fed at a constant rate through the apparatus (Figures 5 and 12) at which time the string 2| and the stamp 22 are affixed at spaced predetermined points. The crease lines l2, l4 and I5 are laced in the stock sheet 26 prior to affixing the ta p and string thereto. After the string and stamp have been attached, the stock sheet'26 is severed along lines intermediate the strings 2| such as along dot-dash lines 21 (Figure 12) thereby forming the covers II] as shown in Figure 1. The means for severing the sheet 26 along the lines 21 is not shown because the invention resides primarily in the apparatus for attaching these strings and not in the severing of the stock sheet, after the strings have been attached.

Glue applying mechanism Before the stamp 22 and the string 2| are attached to the stock sheet 26 it is necessary to provide glue spots 28 to the upper side of the stock sheet at suitable spaced points. These glue spots are applied by a suitable apparatus which is schematically shown inthe right-hand portion of Figure 4, said apparatus comprising a roller 30 above which the stock sheet 26 passes. Disposed above the roller 30 is another roller 3| having raised segments 32 on its periphery, the length of each segment or boss being substantially the same as the length of the glue spots 28. These bosses contact the upper side of the stock sheet 26 as they rotate, and apply the glue thereto. -During the rotation of the roller 3| the segments 32 are adapted to receive their glue from acontact roller 34, said roller 34 being adapted to have glue applied thereto from a glue roller 35. The upper periphery of the glue roller 35 is encased by a glue hopper 36 having glue 31 therein. This machine is conventional and is adapted to be driven in timed relation to the string ain'xing means hereinafter to be described.

Stock sheet advancing mechan sm After the stock sheet of material 26 has passed through the glue applying apparatus and the glue spots have been placed thereon at the desired points, it passes over rollers 40 and 4| and then over the periphery of a sleeve 42 (Figures 5, 6 and 11).. The upper peripheries of the members 40, 4| and 42 are substantially atthe same elevation so as to support the lower side of the sheet 26. Disposed above the members 40, 4|, and 42 and the sheet 26, is a belt 43 which is mounted around

rollers

44, 45, and 46, these rollers being disposed opposite the members 40, 4| and 42, respectively.

The power necessary to advance the sheet of material 26 beneath the belt 43 and above members 40, 4| and 42 is supplied by the member or sleeve 42. This sleeve is rotatably mounted around a rotating shaft 41, the ends of which are rotatably mounted in

uprights

48 and 49, (see Figure 5) said uprights being supported by base member 50. i The sleeve 42 has integral with one end thereof, a gear 5| (see Figures 5 and 12), which meshes with another gear 52 on a shaft 53. This shaft 53 has its ends rotatably mounted in upright 48 and in a bearing plate 54. Also fixedly secured upon shaft 531s a spiraled gear 55 which is driven by another spiraled gear 56 on shaft 51 therebelow. The shaft 51 is driven continuously by a suitable source of power. It is seen that the rotation of shaft 53 in Figures 4 and 5 will cause the gears 5| and 52 to rotate the sleeve 42 in a clockwise direction in Figure 11 to continuously advance the stock sheet 26 through the apparatus.

Top'roll lifting and lowering mechanism The end of string 2| is positioned above the top of the stock sheet 26 at a point directly between the rollers 40 and 44 (Figures 6, 11 and 12). In order to properly position the string relative to the sheet as it travels through the machine, it is necessary to provide means for raising the rollers 44 and so that a gap, as shown in'Figure 6, will be provided between the lower side of the belt 43 and the upper sides of the rollers 40 and 4|. After the end of string 2| and the stamp 22 have been properly positioned,-the belt 43 and the

rollers

44 and 45 are lowered to'the position shown in Figure '11 to press the parts in contact with each other, The portion of belt 43 which is beneath the roller 46 will not be raised during normal operation of the machine because the stock sheet must be held against the driving sleeve 42. The means for raising and lowering the belt 43 and the rollers and 45 to provide this space for positioning the stamp and the string on top of the stock sheet comprises a lever arm 58 which supports the

rollers

44 and 45. This lever arm is loosely secured around a shaft 59 by means of an attached sleeve 6!] (Figures 5, 6, 10 and 11). When it is desired to form the above mentioned space by raising the

rollers

44 and 45 together with a portion of the belt 43, it is necessary to rotate the sleeve 60 together with the attached lever 58 in a clockwise direction in Figures 6 and 10 and 11 thereby causing the desired space to be provided so that the end of a shuttle, hereinafter tobe described, canmove betweenthe lower side of the belt 43 and the upper side of the sheet of material 26.

Sleeve 60 has integral therewith a bell crank 6| having

rollers

62 and 63 on the free ends which contact cams 64 and 65 respectively. Cams 64 and 65 are fixedly secured on the shaft 41. As the shaft 41 rotates the earns 64 and 65 will oscillate the sleeve 60 as well as the arm 58 to cause the

rollers

44 and 45 together with the belt 43 to be raised and lowered at the proper times during the application of the string 2| and the stamp 22 to the stock sheet.

String feeding mechanism As the glue spots 28 on the stock sheet 26 pass through the machine a suitable mechanism is adapted to operate in "timed relation to the movement of the stock sheet to position one end of string 2| directly over the glue spots so that a stamp can be subsequently placed thereover to secure the same in position. Figures 5, 12, 13 and 14 and 15 show this mechanism in detail. It is here seen that a suitable shuttle 61 is provided which has an arcuate slot 68 therein through which the string passes. This slot has an enlarged cavity 68a communicating therewith in which a pivoted dog 69 is mounted, said dog having a serrated point for engaging the intermediate portion of the string 2| to prevent it from slipping relative to the slot whenever the shuttle moves downwardly to position the end of the string on the top of alglue spot 28. This dog 63 normally is held in engagement with the string by means of a suitable compression spring 15.

The shuttle 61 is secured to an arm 12, which arm has its upper end fixedly secured around a shaft I3, said shaft being rotatably mounted in a bracket I4 which, in turn, is secured to the end frame 48. Also secured upon the shaft 13 (Figure 11) and adjacent the member I2 is a gear I6 which normally meshes with a vertically disposed rack 11 and this rack is mounted for vertical sliding movement in raceway I8. It is evident that when the rack 11 is moved downwardly to the position shown in Figure 5 that the lower end of the shuttle 61 will advance the end of the strin 2| to a position above a glue spot on the top of sheet 26 and within the space between the separated rollers 40 and 44 (Figure 6).

The lower end of the rack 11 is pivotally secured as at 19 to a link which in turn is pivoted as at 80a to a lever 8|, said lever having its other end fixedly secured to a shaft 82, the ends of which are mounted in

upstanding members

48 and 49. Integral with the lever 8| and loosely mounted around the shaft 82 is a sleeve 83, said sleeve having

lever arms

85 and 86 also extending therefrom (see Figures 5 and 9). These lever arms have

rollers

81 and 88 on the free ends thereof which contact cams 89 and 9t respectively, which cams are fixedly secured on shaft 41. As shaft 41 rotates the cams serve to raise and to lower the rack H which actuates the shuttle I51 at the proper time. Of course when the roller 88 is on the high side of the cam 90 the shaft 82 has been rotated in such a manner as to cause the rack 11 to be loweredand at the same time toadvance the shuttle 61 and the projecting string 2| substantially to the position shown in Figures 5 and 13. On the other hand, when the roller is on the low side of the cam 90, the roller 81 is on a high side of cam 89 at which time the rack and shuttle have been returned to uppermost position.

The string 2| is severed from a continuous strand 2|a which is drawn through an eyelet immediately before it passes into the shuttle 61. This eyelet is positioned in such a manner that upon the movement of the shuttle and the rack 11 to uppermost position, the string 2| will be drawn between a pair of shearing knives 96 and 91 to be later described so that at the proper time these knives can beactuated to sever the string.

The strand 2Ia is drawn from a package 99, which package is rotatably mounted upon a bolt I00. In order to apply the proper tension to the face of this package, a washer H, a spring I02, and a nut I03 are provided. After leaving the package 93 the strand 2Ia passes downwardly through a guide tube I03 and around friction feed roller "11; then through an eyelet I08, and then upwardly through an eyelet I09 on the end of a pivoted wire I. This wire I is normally rotated in a clockwise manner in Figure 5 by'any suitable means such as the torsion spring 2 (see Figures 4 and 7). From the eyelet IE9 the strand passes through eyelet 95 previously described.

The friction feeder roller IOI (Figures 4 and 5), is rotated in timed relation to the machine so as to feed the strand 22a constantly from the package 99 to the shuttle 61. Figure 4 shows the means for producing the constant feeding action. It is here seen that the roller I0! is fixedly secured on one'end of a shaft I I5 which is rotatably mounted in bracket II6 secured to the upstand ing member 48. The other end of the shaft 5 has a spiraled gear II'Ifixedly secured thereon which meshes with a spiraled gear H8 on shaft H9. Also secured on shaft H9 is gear I25 meshing with another gear |2| fixedly secured on shaft 53. It is therefore seen that through the gears I2I, I20, 8 and II! and the shaft'lli, the feeder roller I0! is rotated in timed relation to the other parts of the machine to feed the strand 22 to the shuttle 61.

Tape feeding mechanism As heretofore stated, it is also necessary to simultaneously position a suitable stamp directly g9 above the glue spot 28 and above the end of the positioned string 2| substantially at the same time that the end of the string is placed in posi tion. The stamp 22 which is shown secured to the cover in Figures 2 and 3, formerly comprised a portion ofan elongated tape. This tape will be designated by the reference character 22a. This tape in Figure 5 has a suitable dry adhesive I25 on one side thereof, which, when contacted by a moist surface will adhere thereto. The tape 50 be seen that the roller I32 has a serrated portion I33 on only a portion of its circumference. The length of this serrated portion is substantially the same as the length of stamp 22. The tape 22a also passes beneath the roller I32 and above another serrated roller I 34. When the serrated portion |33 of roller I32 passes into engagement with the periphery of serrated roller IN, the tape 22a is tightly gripped and is caused to advance until a length of tape equal to the length of the serrated portion I33 is drawndownwardly. After the serrated area I33 passes over roller I34, there is no friction between the rollers I32 and I34 and tape 22a; consequently no tape will be fed until roller I32 makes substantially 65 ously with the advance of the shuttle.

75 tion of the stripper.

. anotherrrevolution. The roller I32 is fixedly secured upon a shaft I35 which extends through the supporting framework I36 for the abovementioned rollers I30, I3I, I32 and I34. The

5 projecting end of the shaft I35 fits into squared cavity I31 of another shaft, I38 (Figures 1, 5, and '1). This shaft has a gear I39, fixedly secured thereon which meshes with another idler gear I40, said idler gear I40 also meshing with a gear I2I in shaft 53 previously described. It is therefore seen that as the shaft 53 rotates that the shaft I38 and I35, together with roller I32 will likewise rotate and upon'each, rotation of the roller I32 the serrated area I33 will advance the end of tape 22a on top of the end of string 2 I.

Since the tape 22a is in .a continuous length it is necessary to provide means for severing the same at the proper time so that the stamp 22 can be provided'for each individual cover. Figure 11 shows the means which is employed for effecting this severing operation. It is here seen that a shaft I is provided upon which is mounted a bell crank I46, one leg of said bell crank having a roller I41 on its free end which is adapted to ride upon a cam. I48 on shaft I35. This cam has a high place I50 thereon, which, when contacted by the roller. I41 will cause the bell crank to rotate in a clockwise direction. I The other leg of the bell crank I46 has mounted thereon as at I52, ablade I53, said blade being held against a stationary guide I54 by any suitable means such as a tension spring I55. A stationary shearing member I56 is disposed opposite member I54 and this member I56 also co- 5 moved in timed relation to each other. The

' bell crank I46 isoscillated to cause the blade I53 to shear the lower end of the tape 22a off at the proper time and mellow it to fall at the proper time onto the string 2I and glue spot28 to be 50 moved along therewith to be engaged by the lower side of the belt 43 which belt presses it upon the string 2I and the glue spot 28.

It will be noted by referring to Figures 5 and 13 that when the shuttle has reached its lowermost position while advancing the end of the strand 2| a, that the projecting end of the strand is doubled backwardly in substantially a parallel position to the end of the shuttle. It is essential that the end of this string be straightened to 60 point away from the shuttle so that it can be properly positioned upon the top of the stock sheet 26 prior to applying a stamp 22 thereon. Aswill be seen in the drawings, a suitable stripper I60 advances towards the shuttle simultane- In' other words, upon each operation, the stripper I60 moves to the left (Figure 5) whereas the shuttle 61 moves to the right and when the two meet each other, the leading end of the shuttle pene- 70 trates a slot I 6| in the upstanding leg of the stripper member. The stripper member also has a bridge I62 at the lower portion of the slot I6I and this bridge member serves to separate slot I6I from a second slot I63, in the horizontal por- Whenever the parts have operates with member, I54 in directing the end reached a position as shownin Figure 13 the direction of travel for each member is reversed, and as a result the members move away from each other. Upon this reverse movement the leading end of the doubled strand 2 Ia falls downwardly into the slot I63 and beneath the bridge member I62. Upon farther backward travel of the shuttle and stripper, the strand is straightened out on top of the bridge I62 in the manner shown in Figure 14. The parts continue to separate from each other until they are in the position shown in Figure 15, at which time the end of the'strand 22a overlaps the edge of the stock sheet 26 a substantial amount. It is while the end of the strand is in this position, that the stamp? 22 is affixed on .the upper side thereof at a point where the glue spots 28' are positioned.

The means for moving the stripper member I60 toward and away from the shuttle comprises a rod I 10, said rod being mounted for reoiprocatory movement in upstanding member 49. The other end of the rod I10 has pivotally secured thereto as at IN, a down-standing lever I12 and the intermediate portion of this lever has a'roller I13 secured thereto which contacts the face of a cam I14. This cam is fixedly secured upon the end of shaft". The lower end of the lever I12 is pivoted as at I15 to the base 50. In order to normally hold the roller I13 in contact with the cam I14, a suitable compression spring I16 is mounted around the rod I10, at a location between the stripper I60 and the end frame 49. However, when the roller I13 rides upon thehigh side of the face cam I14, the stripper member I60 will be moved to the extreme right hand position in Figurefi. e

The face cam I14 is rotated by means of shaft 41, said shaft being rotatably mounted in

upstanding members

48 and 49, previously described. The other e'nd of this shaft has a pinion I80 fixedly secured thereon, which pinion also meshes with the gear I2I thereabove. 5 Immediately upon the straightening of the end of strand 2Ia upon the glue spot 28 in the manner shown in Figure 15, the adhesive stamp 22 is severed from the end oftape 22a. Thereafter, thevrollers 44 and 45 are caused to move downwardly'from the position shown in Figure 6 to the position shown in Figure 11, where the stamp 22, the end of strand 2Ia, and the stock sheet 26 are pressed together. The mechanism for causing these rollers to be moved downwardly, to the position shown in Figure '1, has been previously described in connection with the cam mechanism shown in Figure 10.,

Whenever the rollers 40, H, 44 and 45, and belt 43 grip the stamp 22 and the strand 2Ia and the sheet material 26, the shuttle 61 immediately turns to its uppermost dotted line position as shown in Figure 5. During this upward movement the end of the strand is gripped by the above-named belt and rollers against the upper surface of the stock sheet 26. The shuttle will therefore slide relative to the string causing the length of string between theend of the shuttle and the edge of the sheet 26 to be increased to several inches. Also while the shuttle returns to dotted line position the strandis positioned in between the shearing knives 96 and 91 Strand clipping apparatus With one end of the strand clamped upon sheet 26 below the belt 43 and above the rollers 40 and 4|, and above the sleeve 42, and with the shuttle 61 holding the intermediate portions thereof, be-

tween the shearing blades 96 and 91, the next operation to be performed is the clipping of the strand. This clipping is effected by rotating the movable blade 96 in a counter-clockwise manner about its pivot point I88 (Figures 7 and 11) to thus cause this movable blade to pass in close proximity to the stationary blade 91 and shear the strand.

The movable blade 96 is secured on the free end of a lever arm I8. The other end of the lever arm I8 has pivoted thereto as at I82 a vertically disposed link I83, said link having its lower end pivoted as at I84 to an arm I85. The arm I85 is fixedly secured upon the shaft 59, which in turn is mounted for oscillation in the

upstanding members

48 and 49 previously described. Also fixedly secured upon the shaft 59 is a bell crank I81, one leg of which has a roller I88 thereon for engaging a cam I89 and its other leg having a roller I98 thereon for engaging a cam I9I. Both cams I69 and I9I are fixedly secured upon shaft 41. The shape of these cams is such as to effect the raising and lowering of the movable knife 96 to shear the strand 2Ia at the proper time thereby leaving a string 2| attached to sheet 26. It will be noted that the strand is sheared so that a short length thereof will be left projecting beyond the end of the shuttle and this projecting end is that portion which is adapted to be straightened upon the next operation with the stripper mechanism which is shown in detail in Figures 13, 14 and 15.

String removing apparatus After the string has been sheared as described v in the preceding operation, it is necessary to provide means for moving the string in the same direction as the stock sheet 26 is moving through the machine so as to prevent the severed end from becoming entangled with the shuttle and other moving parts upon the next operation. This removing operation is effected by a hook member I which is an integral part of a rack bar I96. This rack bar has suitable teeth in the lower side thereof which mesh with a gear I97 on shaft I98. Also fixedly secured upon the shaft I98 is a smaller pinion I99 which meshes with a set of rack teeth 206 on the rack bar I7, previously described. Whenever the rack bar I'I moves downwardly to cause the shuttle to advance the end of the strand 2Ia over the glue spot 28, the teeth 266 in this same rack bar cause the pinions I91 and I99 to rotate, which, in turn, will move the bar I96 and its associated hook I95 to the right at a speed considerably faster than the normal travel of the stock sheet 26. This movement of the bar will cause the loose ends of the string 2| to be moved forwardly so that it will be out of the way of the mechanism during its next operation of applying a string and a stamp to one of the glue spots.

Upon the return of the shuttle to uppermost position the hook I95 and its associated rack bar I66 will simultaneously move to the left in Figure 11 so that the hook will be disposed behind the next succeeding string which is at that time being attached to the top of the stock sheet 26. Of course when the shuttle is again withdrawn and the strand severed this hook I95 will again move to the right and engage this string to move it to the right in the same manner as the preceding string was moved. In order to prevent this string and the labels from becoming entangled with the rack and gear members, a suitable guide member 205 is provided which serves to house the gears I91 and I99 as well as the rack member I96. This guide is supported by the base. member 50.

Supporting means for the stock; sheet It is very essential that the stock sheet 26 be sufficiently supported on its lower side beneath the glue spot 28 when a strand and stamp are being affixed thereto. In order to provide a supporting means between the rollers 46 and II at a suitable distance from the edge of the stock sheet 26, a suitable plate 286 has been provided (Figures 5, 6, 11 and 15), the lower end thereof, being secured around shaft I96 and its upper end fitting into a groove 46a in roller 46. The right hand end of the plate 286 rests in close proximity to the periphery of the roller 4i and the upper edge of the plate 266 is flush top with the rollers so that it will support the lower portion of stock sheet 26, Therefore, the pressure exerted by the belt 43 and the

rollers

44 and 45 will be sufliciently resisted to cause the stamp 22 to thoroughly secure the end of the strand 2I to the glue spot.

By referring to Figures 5 and 15, it is seen that the roller 48 has a restricted portion 48b integral with its right-hand end. The purpose of providing the portion 46b is to have a rim against which 1e lower side of the sheet 26 is pressed by the downward pressure of the rollers thereabove. This rim will serve to imbed itself slightly into the bottom of the stock sheet 26 and cause a slightly greater pressure to be exerted along a line parallel to the edge of the stock sheet, and thereby serve to more firmly afiix the stamp 22 to the glue spots along this line.

Top roll pressure relieving mechanism It is often desirable to release the pressure that the top roller 46 exerts upon the stock sheet 26 and the sleeve 42 therebelow. By referring to Figure 11, it is seen that the roller 46 is rotatably mounted on the left-hand end of a lever 2I2, said lever being mounted for oscillation around shaft 59 previously described. The upper right hand end of the lever 2 I2 is adapted to be engaged by an eccentric 2I3 pivoted as at 2I4 to the upstanding end member 48. Integral with this eccentric is a lever 2I5. When it is desired to release the pressure exerted by the roller 46, it .is I

vided for normallycausing the roller 46 to exert a downward pressure upon the stock sheet 26 and the sleeve 42 therebelow.

The method of operation of the apparatus is substantially as follows: First the stock sheet 26 with the moist spots of glue 28 applied thereon is advanced toward the

rollers

44, 45, 46, 46 and M and toward the sleeve 42. At this time the

rollers

44 and 45 are raised so that only that portion of the belt 43 between the roller 46 and sleeve 42 will clamp the stock sheet 26. As the moist glue spot gets between the rollers 46 and 44, the shuttle 61 advances the strand 2Ia and at the same time, the stripper I60 is moved toward the shuttle to engage the end of the strand. Then both the shuttle and the stripper withdraw from each other thereby effecting a straightening operation of the string so that it will lie flat on top of the glue spot 28. When the glue spot 28 passes beneath this strand, a gummed tape 22a is advanced over the strand, which tape is sheared just as the

rollers

44 and 45 together with a portion of the belt 43, are lowered into clamping engagement with the sheared stamp and the end of the strand. After the shuttle has retired to substantially the position shown in Figure 15, it temporarily halts until the clamping rollers engage the string and the severed stamp. The shuttle, then retires all the way to uppermost dotted line position as shown in Figure 5, after which the string is severed at a point slightly beyond the tip of the shuttle. The severed attached string is then engaged by the hook or kicker member I95 and is moved in the same direction as the stock sheet 26 is travelling but at a substantially greater rate of speed. This kicking operation is provided to get the loose end out of the way of the parts for the next operation.
