To all whom it may-concern:

Be it known that I, AUBREY H. HARWOOD, a citizen of the United States, and resident of Lynchburg, in the county of Campbell and State of Virginia, have invented certain new and useful Improvements in Mouthpiece Cigarettes wit-h Crimped Scam and Methods of Making the Same, of which the following is a specification. v

The present invention relates to crimped mouth-piece cigarettes and the method of making the: same and more particularly to mouth-piece cigarettes provided with a crimped seam extending over the body and mouth-piece of the same; and has special reference to the making of such cigarettes in continuous rod form.. n A principal object of my present invention relates to the making of crimped mouth-piece cigarettes in continuous rod machines. In the standard form of cigarette rod machines a continuous cigarette rod is made by advancing a continuous web of cigarette paper onto which a tobacco charge or filler is continuously fed, the paper after receiving its charge of cigarette filler being wrapped or rolled thereabout and fashioned into cigarette form, the edges of the cigarette paper bein then secured together a by pasting one 0% the edges and attaching the same to the opposite paper edge. After the cigarette rodis obtained the same is cut into. cigarette lengths or units, each cigarette unit being provided with a pasted seam. To comply with the demands of the trade in various localities and to eliminate various objections in the methods of manufacture'of these pasted seam cigarettes it has long ago been proposed to unite or secure the edges of the cigarettes with a crimped instead of a pasted seam. A common method of doing this consists in feeding the cigarette paper with its filler through a crimping mechanism usually consisting of a small, finely knurled wheel over which the edges of the cigarette paper, folded into an interlocking'seam, are moved, this small, knurled wheel operating in conjunction with a companion wheel or knurledtongue tocrim'p the said seam. This crimping mechanism has been applied to the standard forms of continuous rod cigarette machines, the cigarettes obtainedthereby being provided with a crimped, in lieu of a pasted Although cigarette machines of this type 'rovided with crimping mechanism have een usedto produce crimped cigarettes, the

cigarettes so produced have, as far as I am aware, been always made plain as dis tinguished from cigarettes having mouthpieces such, for example, as cork tips, a numberof difliculties inherent in continuous rod crimping machines presenting them.- selves when the same is desired for making mouth-piece cigarettes. In making mouth-piece cigarettes such as cork tip cigarettes in continuous rod machines, mouth-piece or tipping sections are attached at spacedv intervals to the advancing web of cigarette paper and the paper and attached mouth-piece sections are rolled or wrapped about the cigarette filler to provide a continuous cigarette rod. In making the rod in all prior machines of this latter type known to me the edges of the cigarette paper are joined by a pasted seam asdistinguished from a crimped scam, the crimped seam being difiicult of attainment in continuous rod machines equipped with tipping or mouth-piece attaching mechanism. After considerable experimentation I have found that one of the defects-involved resides in the fact that in making, the interlocking scam in the edges of the paper arid tipping material for crimp-mg purposes too many layers of the paper and tipping material are past between the knurled wheels, this presentingcumulatively too great a thickness of material for passage between the knurled companion wheels, resulting in a'defe'ctive crimped seal. Another difliculty or defect that I have found lies in the tendency of the mouth-piece material such as cork to break or crack when folded into an interlocking seam. These and other disadvantages are' present from an operating viewpoint when it is desired to use crimping mechanism" with continuous rod tipping machines or tipping mechanism with continuous rod crimping machines.

After extensive experimentation to the end of meeting the demands ofthe trade in various localities for mouth-piece cigarettes having a crimped seam throughout, I have.

found that thestandard cigarette rod machines may be provided with crimping and manner for producing crimped mouth-piece cigarettes in'which' the defectsand disadvantages above mentioned are successfully obviated. More specifically, I have found that the mouth-piece or tipping material may be so proportioned and arranged relatively to the cigarette paper to which it is attached that the multiple layers of added thicknesses of material at the seam of the cigarettemay be eliminated, while at the same time the necessity for folding the tippiece cigarettes provided with a crimped seam throughout the length thereof including the mouth-piece of the same may be suc cessfully accomplished.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the method and the article produced thereby, defined in the claims appended hereto.

In the drawings:

' Figure 4 is an enlarged fragmentary view with parts broken away of a completed cigarette made in accordance with my method,

Figure 5 is a cross sectional view thereof talen through the mouth-piece material, an

Figure 6 is a perspective view of a com pleted cigarette.

Referring first to Figure 1 of the drawings, I show in a conventional manner the various steps of making the cigarette rod and cutting the same into cigarette lengths or units. The web of cigarette paper 10 is unwound from a reel of cigarette paper 11 and is advanced through the various parts of the continuous rod machine, the said cigarettepaper web being first moved past a tobacco charging or filling station 12, the tobacco filler 13 being here deposited in a contlnuous manner upon the advancing web of cigarette paper. Although I have illustrated in Figure 1 the depositing of the cigarette filler by showering the sameon the cigarette paper, it will be understoodthat this showing is merely conventional, as my invention may be practised in the continuous rod machine of the pre-formed filler Lemme arette paper from the reel 11 to the tobacco filling station 12 tlfe mouth-piece sections or tipping material are attached at spaced intervals to the underside of the said paper web. To this end I provide'a tipping mechanism which is conventionally shown in Figure 1, the said tipping mechanism comprising means for advancing a web of tipping material such, for example, as a film of cork 14 unwound from a reel 15, the said cork web being guided by the guide roller 16 and intermittently fed to a cutting drum 17 cooperating with a presser roller 18, these parts cooperating to feed the cork web and out the same into mouth-piece sections or units. The severed sections are then attached to the underneath of the cigarette paper 10 and to this end these sections such as 19 are passed between the presser roll 20 and the presser cam drum 21', it being understood that the upper surface of the tipping material issuitably supplied with adhesive in any Well known manner prior to feeding the same between the presser 011 20 and the presser cam drum 21. With the provision of these means the mouth-piece sections 19 are attached at spaced intervals on the Web 10 during the advancing movement of the latter.

For forming the cigarette rod the advancing -web of paper 10 with the attached mouth-piece sections 19 carrying the tobacco filler 13 is moved through forming mechanism, the latter functioning to roll or wrap the cigarette paper about the cigarette filler and to compress the filler to proper proportions as is well known in the. art. This is diagrammatically and conventionally illustrated in Figure 1 and still referring to this figure there is shown provided an endless belt 22 movable over the drum 23 and the roller 24, the said endless belt 22 functioning to grip and advance the web of cigarette paper with its filler through a forming mechanism for forming the cigarette rod,

the filler 13 being, during movement through the forming mechanism, subjected to suitable compression as by means of a compressing wheel 25. After the cigarette rod is rolled into the desired form the edges of the paper web 10 are then joined together and in the present form of my invention I provide the folding means 26 for folding the ed'gesinto an interlocking seam and the crimping mechanism generally designated as 27 adjacent thereto, the said crimping mechanism serving to crimp the resulting folded seam. The crimping mechanism 27 is of a well known construction and comprises the small, finely knurled crimping wheel 28 arranged on a suitable support 29 and the knurled wheel 30 cooperating therewith, the multiple layers of paper in the folded seam being passed between the knurled wheels'28 tempts 'rod is then advanced to a cutting mechanism generally designated as 31, this cutting mechanism being of any approved type, comprising a cutting member 31 having a compound motion, the latter being movable in opposite directions longitudinally of the machine and oscillatably movable into cutting contact with the continuous cigarette rod 32, the cutting member 31' comprising the usualrotatable cutter. The cigarette rod 32 is moved through the guide 33 forming part of the cutting mechanism 31 as is Well known in these devices, the cigarette rod 32 being severed into cigarette lengths or units 34 by means of this cutting mechanism.

As hereinbefore referred to, a principal object of my present invention relates to the making of crimped mouth-piece cigarettes %y the continuous rod method as shown in igure 1 of the drawings, in which the cigarette rod ma be crimped throughout the length thereo including the mouth-piece material. For the pur ose ot successfull crimpin the cigarette t roughout its lengt l have ound it highly desirable to join the cigarette paper edges and the edges of the mouth-piece material in such a manner as to reduce to a minimum the number of layers of paper and material passed between the v crimped wheels of thecrlmpin mechanism.

To this end I have found it e cacious to so join the edges of the tipping or nmuth-piece material as to have no part of the same form. part of the interlocking fold of the cigarette paper edges. Moreover, I have found that the edges of the mouth-piece material may be joined without interlocking the same, no

folds or bends being provided therein, break-' ing or cracking of the cork where cork is used for tipping material being thereby successfully prevented. To the accomplishment of these ends I proportion the mouth-piece material and attach the same relatively to the cigarette papef to provide or leave free marginal edges of the cigarettepaper on both sides the mouth-piece material, the

marginal edges of the cigarette paper only being inter-folded to provide the interlockin seam, the interfolding. of these edges hem obtained without interlocking o interfolding the edges of the mouth-piece sections. Referring to Figure 2 of the drawings, I show the manner in which the mouthpiece sections 19 may be attached to the cigarette web to obtain the desired ends, and referring to this filgure I show the mouth piece sections .19 o a width smaller or less than the width of the cigarette web 10, the said mouth-piece sections being attached to the web 10 in a manner to provide the free marginal edges 35 and 36 in the cigarette paper. As an example it may be added that the marginal edge 35 may be about 1 millimeter and the marginal ed e 36 about 2 millimeters in width, the widt of'the cigarette paper 10 being about millimeters. The marginal edge 36 is therefore made about twice as wide as the mar inal edge, to

permit the desired interloc ing, as will become clearer hereinafter.

By the provision of this method of attachment of the mouth-piece sectidns on the cigarette paper I am enabled to feed or ad- *vance the cigarette paper through and between the elements of the crimping mechanism for efiecting a crimped folded seam in the cigarette pa er, while preventing the multiplication 0 layers of material in'th'e mouth-piece sections, the latter forming no part of the cigarette fold, while at the same time permitting the crimping of the cigarette rod throughout its length, including the mouth-piece material. This is shown more particularly in Figures 3 to 5 of the drawings, and referrring to these figures, it will be seen that as the cigarette rod 32 is advanced and the edges of the cigarette paper. provided with the folds such as 37 and 38 with these folds forming an interlock or a lock seam joint as clearly shown in Figlines a and 5 of the drawings, the edges 39 and 40 of the tipping material 19 are brought into butting or slightly lapping relation, no

part of the tipping material being creased or folded or interlocked with the lock seam joint in the cigarette rod 32. Still refe rring to Figures 3 to 5 of the drawings, it will be noted that the tipping material 19 has been so positioned on the cigarette web'lO that in the rolling and seaming of the cigarette rod the edge portion 39 of the tipping material, besides being disposedin slightly lapping relation with respect to the edge 4 0, is disposed directly over the lock seam 10ml:

rovided in the cigarette paper. With this orm of arran ement the seamed cigarette rod is moved through the crimping mechanism to provide the crimp at in the folded seam of the rod and in the mouth-piece section 19, as clearly appears from a consideration of Figures 4 and 6 of the drawings.

its

mechanism and that the free edge 39 of the '7 mouth-piece material is securelyattached by crimping to the crimped fold oiseam of the cigarette aper. By the provision of this means an by providing the edge39 of the tipping material in slightly overla ping relation with respect to the'edge 40 t ereof, l

am enabled. to secure a very firmly attached cork or other tipon the cigarette rod. while at the same time providin the desired crimp throughout the length t ereof.

The ractice of my method and the use of contmuous rod apparatus, provided with tipping and crimping mechanism for the obtaining of crimped mouth-piece cigarettes will, in the main, be apparent from the above detailed description thereof. It will be further apparent, as heretofore recited, that by the provision of my method I am enabled to successfully obtain mouth-piece cigarettes having cork or other tips provided with a crimped seam throughout the length of the cigarettes including the mouthpiece material. It will be further apparent that by the manner of attaching the mouth- .piecematerial to the continuously advancing cigarette paper web in the practice of my invention not only may the edges of the paper web be securely connected in the desired crimped interlocking fold; but that the edges ofthe tipping material may be firmly attached to the crimped fold of the cigarette rod without subjecting the mouth-piece material to any breaking. cracking or splitting,

the cigarettes obtained by my method having been found of uniformly good quality, the production thereof being efiected with a minimum of throw-outs.
