This"inventionwelatesto the manufacture of cigarette paper booklets and more particularly toan improved-"machine for high-speedg-automatic manufacture of'bookl'etscontaining-a-block of "cigarette" papers bonded along OIIBf'BdgB to the booklet-cover and adapted "to-be removed in "seriatim.

The only machine-made "type of cigarette e mt thathas' met with'commercial suco "cess' previously'inthis'c'ountryis'the thinfgiveaway-booklefiwhich' is usuallyattached to a packageofsmoking tobacco. This'b'ooklet containsonly a'feW leaves'of "cigarette-paper; e. g. '15 leaves, which are not"bonded'in the'booklet. Thecoverof this'booklet' ismade of thinp'aper stock and loosely"1olded"around the leaves '"Without'any'scoring of the folded'f'edges. I

The'formingand assembly of this booklet'have alwa'ys required' time"consuming; hand opera- *t'ionssince -nomachine has previouslybee'n de- ---veloped which Would-form -and*assemble"'these booklets-automatically.

In accordance with the -presentinvention, a -machine'has now been developed.- that'will manufacture the five-cent+ty pebooklet-automatically A anda'tia veryhigh-rate of speedi This machine constitutes a marked technical and economic -o improvement in lthisart; considering the-fact that these. booklets are-commonly sold to the tobacco manufacturers and :distributorsin quan- .atities of five million or moreat a time.

One of .themajorj problems in 'automaticvmachine .manufacture of the five-cent type booklet -was the gluin of the cigarette'papers to, the

* backbone edge in continuousstrip formand at -a high rate of ,speed such that the block of papers in the finally cut booklewwould'berse-v -curely held as a block, but yet adapted foreasy removal of one; paperat a time, asneeded by Q the smoker, without disturbing the remaining a papersw This and the; problem ofio'rming and shaping the necessarily relatively stiff-book1et cover stock have heldback'ma-chine manufacl ture of the fiver-cent booklet for the pasttwenty years.

The solution to ithe-"above' problems-involved the devlopment of arotar scoring device which scores the relatively stiff cover materialin con- "-'-tinuous strip form and comprises tworotary l members that" move in" the direction of i movement -o'fthe' co've paper'. This produces a squared; flat+surface backbone edge for secure lo and *uniiorm bon'ding ofthe cigarette 1 paper sheets thereto!

Referring at first to Fig. 1 of the drawing, the cigarette booklet making machine illustrated comprises a base portion 29 which supports a table or platform portion 2|. Substantially centrally located on the table 2| is a feeding device, indicated generally at 22, adapted to feed a plurality of superimposed strips of cigarette paper 23, of indefinite length, enclosed in a wrapper strip of cover paper 24, also of indefinite length. The wrapper enclosed strips of cigarette paper are indicated in Fig. l at 25.

The strips of cigarette paper 23 enter the machine in superimposed relation at the right hand end as shown in Fig.1, the cigarette paper strips 23 being led through an aligning guide 26 from a suitable source of supply (not shown.) The wrapper strip of covering paper 24 is fed from a roll 21, mounted for rotation on a shaft 28 in brackets as indicated at 29, over an idler roll 30. Suitable restraining means (not shown) are preferably provided for regulating the tension on the cigarette paper 23 and enclosing wrapper 24.

The enclosing wrapper strip of cover paper 24 is wrapped about the superimposed strips of cigarette paper 23 at a folding station indicated generally in Fig. 1 at 3|. The feeding device 22 is adapted to draw the strips of cigarette paper 23 and enclosing wrapper 24 through the folding station 3|, and feed the assembled wrapper enclosed strips of cigarette paper 25 to a severing device 32.

The severing device 32 (see Fig. 3) comprises two suitably journaled

shafts

33 and 34 which are parallel and spaced apart. The shaft 33 oscillates in its bearings. Extending upwardly from shaft 33 is a frame 35, and on top of this frame 35a platen 36 is arranged. Secured to the shaft 34 are eccentrics 31. Mounted on the eccentrics are eccentric straps 38, to each of which is attached ends or shafts 39. These rods or shafts 39 reciprocate in corresponding bores 40 provided in the frame 35, and are connected to a crosshead 4| The crosshead 4| carries a guillotine knife 42 which cooperates with the platen 36 to form a cutting means. As the shaft 34 rotates, the guillotine knife 42 reciprocates by reason of its eccentric mounting toward and from the platen 36, and may be operated in this manner to sever the as sembled wrapper enclosed strips of cigarette paper 25 in booklet length.

Simultaneously with the movement just described of the guillotine knife 42, the frame 35 is oscillated on the shaft 33 through the connection formed by the rods 39 which as mentioned above reciprocate in the bores 40. As a result,a swinging motion is imparted to the platen 36 and knife 42 which may be adjusted in accordance with the rate at which the assembly 25 is fed so that the feeding movement of the assembly 25 is not interfered with during the cutting operation.

Beyond the severing device 32, the individual cigarette paper booklets 43 formed from the assembly 25 are fed by a suitable collating device 45 into a collecting device 46 from which they may be removed as desired.

The foregoing elements of the cigarette booklet making machine incorporating my invention are known and have been previously employed in booklet making machines so that it is not considered necessary to detail them further here.

As mentioned above, the cigarette paper booklet making machine of the present invention is adapted for making the five-cent type of cigarette paper booklet, which contains a relatively large supply of cigarette paper, e. g., of the order of or more. A cigarette booklet of this type requires a substantial cover member which will protect the enclosed cigarette papers adequately; and it is necessary to provide an adhesive mounting for the cigarette papers in the cover member so as to maintain the cigarette papers in order over the extended period for which a booklet of this type is used.

The cigarette paper booklet making machine of the present invention is accordingly provided with an adhesive applying means indicated generally in Fig. 1 at 47. The adhesive applying means 41 is mounted at the end of

shafts

48, 49, 59 and 5| which extend in parallel and square-spaced relation from suitable supports 52 and 53 arranged on the table 2|. Further support is provided by pedestals 54.

The adhesive applying means 41 comprises an automatic valve element55 which is disposed in relation to an arcuate guide 56 over which the enclosing wrapper strip of cover paper 24 is drawn as it is advanced to the folding station 3 I. The automatic valve element 55 applies adhesive to the wrapper strip 24, in a manner which will be described more fully below, to provide the necessary adhesive mounting for the cigarette paper when the assembled wrapper enclosed strips of cigarette paper 25 are formed at the folding station 3!. Also, the operation of the automatic valve element 55 is timed in relation to the severing device 32 so that a separate adhesive mounting is provided for each booklet 43 ultimately formed by the severing device 32.

The'automatic valve elemet 55 is supported from a cross-bar 5! carried on extending shafts 56 and 5! Support arms 58 extend forward from the cross-bar 57 and inturn support upstanding bracket arms 59. A shaft 60, having square end portions 6i which prevent rotation, are adjustably supported in the bracket arms 59 to provide a mounting for the automatic valve element 55. The upstanding bracket arms 59 are pivotably mounted on the support arms 58 as at 58a, so that the automatic valve element 55 may be retracted when not in use. A snaplock 59a is arranged to position the automatic valve element 55 in relation to the arcuate guide 56 during operation.

The automatic valve element 55 itself (see Figs. '7 and 8) is composed of a hollow body portion 62 formed with a fiat top surface and havingan internal bore 64 corresponding to the diameter of the shaft 63. A nozzle fitting 65, having a tip 66 adapted to the contour of the arcuate guide 56, and a supplementary tubular fitting 6'! are aligned on the horizontal axis of the body portion 62. A vertically disposed tubular fitting 68 opening into the tubular fitting 61 is also arranged in the body portion 62 as shown in Figs. 7 and 8. As will be explained more in detail presently, adhesive is supplied to the automatic valve element 55 through the vertical fitting 68, and is metered in proper amounts from this fitting 68 to the fitting 6'! and through the nozzle 65 for application on the wrapper strip of cover paper 24 carried by the arcuate guide 56.

The adhesive is metered from the fitting 68 by a plunger rod 69 arranged for reciprocation in the horizontally disposed tubular fitting 61, and adapted in this manner to uncover or close the opening of the fitting 68 into the fitting 61.

A secondfixed collar 99 arranged on the shaft 60 to force a compression spring I against the other side on rods I02 which extend between the previously mentioned support brackets BI and 82. Lateral adjustment of the guide 56 is provided by a shaft I03 which carries the handwheel I04 and has a .threaded portion I05 engaging the guide 56.

This lateral adjustment provision for the guide 56 allows the wrapper strip of cover paper 24 to 1 be positioned properly in relation to the folding station 3|. The previously described lateral adjustment provision for the automatic valve ele- :ment 55 allows the adhesive to be applied at a proper lateral position on the wrapper strip 24. When the automatic valve element 55 and .;arcuate guide 56 have been set in properly ad- ,justed relation, adhesive is applied to the wrapper strip 24 during operation of the machine at a position which is laterally spaced in relation :to one edge of the plurality of superimposed .strips of cigarette paper 23 so as to dispose the .adhesive in position for bonding one edge of the cigarette paper strips 23 (see Fig. 4). As described above, the adhesive is metered from the :automatic valve element 55 so that it is applied to the wrapper strip 24 in spaced deposits as .indicated in Fig. 4 at I06 so as to form a sepa- .rate adhesive mounting for each booklet 43 to be formed at the severing device 32.

To effect adequate bonding of the cigarette paper strips 23 in the wrapper strip 24 at the folding station 3I, the wrapper strip 24 is conditioned With scored lines I0? as illustrated in Fig. 4. These scored lines I01 result in the formation of a squared backbone portion as the wrapper strip 24 is drawn through the folding station 3I. fiat surface which markedly facilitates the bonding of the cigarette paper strips 23 in the wrapper strip 24.

' The scored lines It? are formed on the wrapper strip 24 by a scoring wheel I 08 which is mounted for rotation on a stationary shaft I09 which has square end portions II 0 adjustably supported in the upstanding bracket arms 59 similar to the manner in which the automatic valve element mounting shaft 06 is supported. The scoring wheel I58 comprises a body portion III rotatably fitted on the shaft I09. Annular scoring knives IE2 are in turn fitted ,on this body portion III and a woodrufi key is arranged as shown in Fig. 10, to prevent the scoring knives I I2 from shifting on the body portion I I I'. A spacer ring H3 is disposed on the body portion III between the scoring knives II'2 to position the knives H2 in accordance with the spacing desired between the scored lines I57. This arrangement allows the spacing between the This squared backbone portion presents a an adjusting collar 6 which is carried in threaded engagement with a base member III fixed to the shaft I09. The adjusting collar H6 is disposed in abutting relation with one of the thrust bearings II5 and may be shifted on the base member II! to adjust the lateral position of the scoring knives I I2. A compression spring H8, arranged on the shaft I09 between a fixed collar H9 and the other thrust hearing I I5 renders lateral adjustment of the scoring knives H2 available in either direction. The scoring knives II2 may accordingly be positionedfeadily in correspondence with the lateral adjustment of the arcuate guide 56 and the automatic valve element 55 as previously described. 5 i

paper 24 as it passes over the arcuate guide 56 a roll member I20 is disposed in relation to the scoring knives II2 through an opening in the scored lines IE? to be adjusted for different sizes g of booklets 43, a spacing ring I I3 of appropriate thickness being used for a given size of booklet V 43. The scoring knives I I2 are held on the body portion III by a threaded collar II4 disposed on the body portion I I I as shown in Fig. 20.

The body portion III rotates on the shaft I09 between thrust bearings H5. Lateral adjust- -,ment of the scoring knives is afforded through arcuate guide 56 as shown in Fig. 6. -The roll member I20 is carried on a fixed shaft I2I mounted in the arcuate guide 56. A roller bearing I22 is arranged on this shaft I2I between fixed collars I'23. The roll member I20 which consists of a hardened steel ring is disposed on the roller bearing I22 for free rotation.

In operation the plurality of superimposed strips of cigarette paper 23 enter the machine from the right as shown in Fig. l. The wrapper strip of cover paper 24 is led from the roll 27 around the arcuate guide 56 to a position which disposes it for folding in cover relation to the strips of cigarette paper 23 when it reaches the folding station 3|. The Wrapper strip 24 and strips of cigarette paper 23 are drawn into the machine in this manner by the feeding device 22.

As the wrapper strip of cover paper 24 passes over the arcuate guide 56 it is acted on by the scoring knives II2 to form the scored lines I01. For this purpose the scoring knives II2 are adjusted in relation to the roll member I20 to form clearly defined scored lines I01, but not to: cut the wrapper strip 24- or unduly weaken it. The lateral adjustment of the scoring knives H2 is such that the scored lines I0! are formed in the wrapper strip 24 in relation to one edge of the strips of cigarette paper 23 as indicated in Fig. 4 to result in the formation of a squared backbone portion as previously mentioned when the wrapper strip 24 is drawn through the folding station 3|.

After scoring in this manner the wrapper strip 24 is advanced over the arcuate guide 56 to? the position of the automatic valve element 55." At

vcordingly leaves the arcuate guide 56 with a portion beyond one edge of the strips of cigarette paper 23 defined by scored lines I0'If'and having spaced deposits of adhesive applied to it.

Upon reaching the folding station 3I the wrapper strip 24 is folded in cover relation to .the strips of cigarette paper 23 and the portion of the wrapper strip 24 defined by the scored lines I01 assumes an upstanding position during folding so that the deposits of adhesive are presented in bonding relation to the edges of the strips of cigarette paper 23. The strips of cigarette paper 23 and wrapper strip 24 accordingly leave 9 the foldingrstation 3] as :therassembled 'wrapper.'- enclosed?strips:ofncigaretteepaper5.25.

The booklets 43 formedinthis manner-arecarried-by the collating1device-45 into the'collecting-device 43.

The booklets? 43- are -further conditioned in this collecting device 46 to set the adhesive bonds-It w appears; that when'the' assembled wrapper. en: closed strips of cigarette paper -25:-are=cut-at the severingdevice- 32,- the cutting *operation has av tendency to shift the stripsrof cigarettepaperZB- slightly, and'as the adhesive bond between the wrapper strip 24 v and the cigarette paper strips 1. 23 is still tacky atthis point; the bond'may'be impaired to .some extent -by; -th e-cutting opera! tion.---.The furthenconditioning of the booklets 43 is carried out in th6 C011eCting td6ViC6 -46 toinsurea sound "adhesive-bond, I

For this purpose two electric heating elements- I24 are-arranged on the collecting device 46to apply heat .to--the edge-of the booklets 43 on 25: which-the adhesive bond is-disposed as they are advanced throughthe collecting device (see Fig. 11). The heatingelements-I24are spaced apart sufliciently to-allow the-arrangementof a pressing element-I-25-between-them. The pressingelement-I25 comprises acam I26 (see Figs. 12 and 13) :whichis rotated-inrelation to the advanceof thebooklets- 43through-the collecting device46.- The cam I26 actuate a'pressure block I21 mountedin the side of-the collecting device'35 46.

The improved automatic valve element 55 of. my invention makes it possible to adjust the ads 5 hesive bondI36 to just the right condition. .If too much adhesive is appliedlto vform the bond. I36

. the cigarettepapers I31 will be slecuredto tightly and will tear when anattempt is made to remove them from the booklet 43. If on the otherhand,

1-. not enough adhesive is applied the bond I36 will not be secure. This problem is .further complicated by the factthat adhesives such as gum arabic, ,vary ,from batch tog batch in physical properties. As previously mentioned, the adhesive is forced. to theautomatic valve element automatic .valve element 55 may be adjusted as v described .above to vary the amount of the adhesive deposits applied. These features allow close regulation of the adhesive bond I39 formed,

and make. it possible to obtain satisfactory results with commerical grade adhesives.

While the means and method of the present inventionuare particularly adapted for making cigarette paper booklets as described above, it will beunderstood that my invention is applicable, generally for applying. deposits of adhesiveona traveling web of paper, as definedin the appended I claim;
