"STRAW-COV ERING- MATERIAL FOR MOUTHPIECES OF CIGARETTES AND THE LIKE.

To all whom it may} concern Be. it known that 1, Anne BERNHARD FIscnL, a citizen of the Empire of Austria,

residing at Dresden, Germany, have invented a new and useful Improvement in Straw- Covering Material for Mouthpieces of Cigarettes and the like, of which the following description and drawings are a full and accurate specification.

, My invention relates to mouthpieces for cigarettes composed of straw, and consists in a novel material therefor, consisting of bands of silk paper covered with parallel,

slitted and flattened straw stalks, bound together by means of adhesive plates or tabs,

and in a process for making the same.

Cigarettes with a mouthpiece covering made of .slitted and flattened straw stalks have beenmade for seventeen years and have be. usedv because 1t is rather brittle, would l 30 not roll uniformly, and its edges were easily torn, and also because the .raw material comes into commerce in pieces of rather small sizes.

This raw material consists of little leaves of silk paper, upon which are pasted slitted, flattened and parallel straw stalks. Mechanical production of the raw material has not been possible,,,up to the present, while production by hand is too expensive. Mechanical production would, however, not be very useful, for the dimensions of the straw covered leaf of silk paper is limited in one direction by the knots of the straw stalks. The procurable straw stalks are ordinarily not longer than about eighteen centimeters. The dimension in the other direction is not limited, that is, endless strips of paper could be pasted.

After many efforts the inventor has been able to produce spools or bobbins, for utilizing the raw material found in commerce, which spools are adapted for mechanical operation in a cigarette machine or in a machine for covering of the wrapper paper, somewhat like the bobbins adapted for cork or gold leaf coverings,

Specification of Letters Patent.

Cigarettes with straw mouthpieces are thus produced, which are far superior to the hand-made product in cleanliness and in uniform appearance. The superiority of the mechanically made product consists in having the fibers of the straw completely joined to the circular or elliptical periphery of the cigarette and parallel to the axis, and alsoin producing a uniform reflection of the light. On the other hand the cigarettes with hand made mouthpiecesare inferior in the fitting to the periphery of the cigarette and in the parallelism of. the threads of the straw, and they do not reflect the light in all directions in a uniform manner.

It is old to overcome the brittleness of the starting material by pulling it over an edge on the side of the silk paper, as for example, when a rolled-up drawing is pulled over the edge of-a table, to flatten it. However, a perfect and uniform flexibility or suppleness of the straw covered, leaves could not be thus obtained, and the further manipulation of the material so treated seemed impossible. This, however, has been obtained by the inventor, after many failures, in a manner that will be set forth in the disclosure of the.

machine. It was determined to fasten together the before-mentioned short pieces of the straw pasted paper, along their long sides, by means of adhesives, tabs or plates, or on a long tape. An overlapping pasting of the pieces did not appear suitable because of the thickening. at the place of pasting, while the adhesive material could not hold on the outer surfaces of the straw stalks, which were coated with silicic acid. Besides, the overlapping would still further lessen the short single pieces. Besides, the above-mentioned treatment for the first time permitted the possibility of fasteningthe single pieces end to end, for rendering them pliantor elastic. These lateral edges lie so perfectly flat and the brittleness of the stalk pieces is so perfectly overcome at the ends, that two lateral edges may be joined together on the adhesive tab or plate and the cigarettes which are not sub ected to pressure, are not worthless. A groove resulting from a circumferential tear is not in u r1- ous, if the torn stalk is not readily distinguishable through its color.

The drawings show different views of the machine for carrying out the PTQWSS and making the material.

Figure 1 is a front view,

. upon the paste core f. The Winding up camera the direction of the breadth of the stalks as tliey are found in the starting materialof commerce: The cuttingto get the covering strips shown'in Fig. 5' can be done in the well-known manner, either before, during,- or after the winding up.

The remaining-figures. show the machine for making the material pliant.

Both rollers I and 2 are covered with soft rubber or the like. They are uniformly driven by th'e'pull ey 3 and the spur wheels designated in Fig. 4' as 5, 6, 7. The number otteetlrof the spur wheels 5' and 7 is different, so that the roller 2 revolves somewhat more quickly than the roller 1 and thereby creates a pulling effect upon the material. Between both rollers-is the bolt 8', having a sharp edged lower surface, perpendi cular to both side faces. If the bolt 8 ispulle'd down by means of lever 9,'bar 10, and a foot rest not shown, or the like, as far as the limiting screw 1-1 permits-, both edges 'ofthe facesof the bolt press some"- What into the soft roller covering.

The straw covered silk paper is driven over the table 12,; so' that its front edge is gripped by the bolt 8'. The straw threads are thereby pulled laterally over the table 1-2 th'e silk paper being above and the straw being below, thestraw being th ns joined'to the paper in thisinstance before it is rendered pliant.

Asthe edgesof the bolt 8 presssomewhat into the roller'covers, the effect is not the same as if a leaf oflithe material is" merely draw n' oyer 'a sharp edge; also be produced by one roller. Fiber'a'fter fiber of each straw stalk is successivel" pressed into theroller cover, and led arounc" The effect may the sharp edges of the bolt 8, so that the binding web between the consecutive fibers is powerfully pulled and thus loosened and its brittleness is destroyed. This is repeated at the second roller. At the same time another pulling and stretching of the material I occurs between the rollers. The combined result 1s a perfect and uniform pliantness of the raw material, and besides a handsome pieces, the fibers of the straw will lie parallel to the axis of the cigarette, and conform perfectly to its cross-section, si'ncethe con nection between the consecutive fibers has been loosened, as above stated After the raw material has been thus rendered pliant, the covering strips of straw for making the mouthpieoes are cut into proper widths to be fed into the cigarette m alring machine:

Having thus described my invention, what I desire to secure by Letters Patent is 1. A straw coveringfor mouthpiec'es of cigarettes, consisting. of parallel, slitted, and flattenedstraw stalks, said flattened stalks being fastened together by adhesive means, and having the binding material between the fibers of the stalks stretched and loosened, the width of said strip being such that it can be directly fed into the cigarette making machine.

2. A straw covering for mouthpieces of cigarettes, consisting of a tape, said tape having fastened thereto slitte'd and flat tened straw stalks, the adjacent edges of said stalks touching each other without over-lapping, said stalks being arranged so that-their fibers parallel, and ha-ving the binding web' between said fibers stretched and loosened, the width of said tape being such that it can be fed directly into the cigarette making machine.

In testimony that I claim the foregoing as my invention', I have signed my name in presence of two subscribing 'vitne'sses.
