Method and machine for making perfectly shaped cigars with conical ends.

The invention relates to a method and a machine for the production of cigars, in particular cigar bunches, at high speed. A cigar bunch is the general one cylindrical structure representing the cigar filler tobacco contains, 4 can be a short or long filling tobacco that wrapped in a bottle, commonly called a cigar binder iit. However, the invention is not limited to the production of clay egg coils alone, as they are made with small amounts Modifications for the application of a cigar cover sheet to the collar to form the finished cigar, is adaptable.

The machine hexing of cigars is long For years the covenants in so-called Bundwiokelmaeohinen has been manufactured · In machines of this type, a

Cigar bundle ties made from a natural tobacco leaf or from a composite tobacco cut to a suitable shape and placed in a predetermined position on the wrapping cloth Cigar bundle wrapping machine placed. The fill aoak will open the wrapping cloth, generally in a loop of the same, and the loop is continuously moved forward in such a way that that the filling tobacco is wrapped in a substantially cylindrical shape and wrapped in the binder, which during the ^ The winding process to form the cigar bunch is helical around the filling tobacco is applied Federal cone-shaped according to the desired ^ n iOrm of the finished Train cigar.

In the bundle winding process, each bundle is

produced as the result of an individual wrap operation in which an individual labak batch. or bundle filler batch as it is called - is wrapped together with the individual tobacco binder. The binder is usually narrow and relatively long, and since it is wrapped around the filling tobacco in several screw turns, the length of the wrapping cloth is correspondingly long. The process is understandably slow since the wrapping loop of the swaddling cloth has to carry out almost a complete longitudinal hike over the wrapping table and then be brought back to its starting position at the beginning of a new wrapping cycle. For the maintenance of each bundle winding machine a separate operator must be provided.

is the main potato in the cigar manufacturing lot.

In order to remedy the relatively slow cigar bundle production, which is caused by the single bundle winding process, has already been tried, the cigars in one

to the
Manufacture processes that / generally resemble those used in modern machine cigarette manufacturing. J3ei the method of time generally used for machining Vo-n cigarettes, the shredded 'fabat by a ächütt funnel a traveling forming Ia ^ ierband supplied LJiTt ₁ lying on a conveyor belt. The tape carrying the paper runs into a so-called cigarette stoker, which first folds the paper around the tobacco in an essentially U-shaped shape and gradually rounds both paper and tobacco to a cylindrical shape, with the edges of the paper overlapping in order to follow to form a longitudinal seam after gluing. The continuous structure produced in this way is the so-called cigarette rod.This is cut into the desired lengths in order to form the individual cigarette. It is pointed out that in this process the cigarette rod is continuously formed without interruption and this with modern machines almost at high speed 2,000 per minute, whereas cigar bunches are produced in Jüinzelf production on the bundle winding machine with an output rate of 20 per minute.

The diameter of the cigarettes, which ouen after deia described method are produced is constant. Various improvements have been introduced into the process been, u.,; the concentration of tobacco at different levels

909884/0124 BAD original

Places along the length of the cigarette, usually at the and en to change} affects this change in concentration but not the cigarette diameter.

As far as the applicant knows, the tobacco products, like cigars, Lanila cigars, long, raw cigars and others that use a cigarette rod manufacturing process similar processes, of a raw, cheap type with the same diameter over the entire length. Better cigars are generally shaped at their ends and it has not heretofore been possible to manufacture such commercially acceptable cigars by the rod making process to manufacture.

It is therefore an object of the invention to continuously produce cigars with shaped ends at high speed To manufacture strand manufacturing processes.

The main feature of the invention is a mechanism that a constantly moving forward, in certain V / eise formed tobacco stream, which afterwards in a continuously moving band of tobacco to form a continuously continuous, essentially cylindrical cord with regularly spaced short spots with less aici Filling tobacco is wrapped in it.

Another feature of the invention is a mechanism which cooperates with that of the first feature to create the To compress the tobacco rod at the points with less varnish, so as to turn the strand into a continuously ongoing one To reshape the length of stepped cigar bunches with tapered ends.

The separated bundles of eggs with tapered ends may later be used in cover sheets to form the desired finish shaped cigars to be wrapped.

In the method proposed here, the

Jüll tobacco, which is shaken on a moving belt, un | to form the moving tobacco stream (or ribbon) before it is wrapped in the binder from an excess of Tobacco compared to what is required in the federal government. The excess is such that the cross-sectional area of each transverse element subs is greater over the entire length of the stream than required in the collar to be formed later. While the stream of tobacco moves towards the cigar rod maker, it is subjected to a single dosing (stripping) operation (trimming). The stream preferably moves horizontally and the scraper is preferably arranged so that its position regularly at predetermined intervals vertically in each of two positions with respect to the current is adjustable. In its upper position it continuously acts on the current in such Height, that he (. Only removes the excess. This ensures that there is enough filling tobacco in each individual cross-section of the finished covenant is available. The scraper is arranged to be depressed at predetermined intervals in its lower position, so as to a greater quantity of tobacco from limited lengths of the stream

909884/0124 _BAD original

to strip off. Therefore, after stripping the stream aas, there is a series of relatively long, higher sections, which are covered by relatively short, lower sections. As a result of this, the filling tobacco has alternating sections of compact and less compact within the tobacco band cigar strand cover ! volume-acting press tools or press rollers are operated at suitable time intervals to shape the oil as desired, cone-shaped, rounded or in some other way.

It has been found desirable to use the composite tobacco ribbon that the, linder zum Wrapping the covenant forms so that it can be wrapped neatly around the conical sections of the stream This amendment can take many forms. A preferred form that has proven successful is the Removal of a number of aligned small diamond-shaped sections across the tape at each of the locations, on which the cone is to be formed. The removal of these rhombic-like shaped surfaces enables the tape to "advance" the separation into individual collars in order to press the cones at the connection point between the collars.

The invention can be understood with reference to FIG

As previously mentioned, an excess of tobacco is applied to the band 2 so that each elementary cross-section of the formed tobacco stream or band is thicker than required for the finished formed band. A hollow chamber 3 is connected to a suction source, not shown, by means of a downwardly extending neck 3A. The upper surface of the chamber 3 is perforated, so that if the perforated endless band, which carries the TaDakstrom, which is formed by the application of the JTüllabaks on the band 2, is advanced over the upper surface of the hollow chamber 3 , it the Is subjected to suction. The suction acting on the stream compresses it so that after the metering or stripping, which will be described later, it is of substantially uniform density and cross-sectional area. After the compression and before the dosing or stripping, however, the thickness of the stream is greater than that required for standardization by the federal government because of the excess tobacco applied. Furthermore, the suction strives to hold the stream or the strip securely in its position, so that it can advantageously be processed by means of a shaping dosing (scraper) Hades 15 in the vibrating dosing device (scraper) 4 in a manner to be described later.

An andloeses belt 7 is driven by a Bolle 7A, which in turn is driven by a power source not shown. The belt 7 is on tension rollers 7B and 7C drawn before it is put into the cigar rod former

A continuous band of composite Tobacco, which serves as a casing or binder for the bundle, is drawn off from a spool 5A and runs over tension rollers 5B 50 and 5E in a position above the Eolle 7A, where there is the endless Tape 7 superimposed when this enters the strand forming apparatus.

After it has been shaped by the stripper in the manner described, the tobacco stream runs onto the tobacco band and moves with it through the cigar rod former This comprises a tongue 8A, a folder 8B, a gluing device 8C and a sealing device 8D, the are all known. The tobacco rod former forms the tobacco stream and the tobacco binding band below it progressively from a flat planar sheet to a progressively deeper U-shape and then to a substantially cylindrical shape around, slightly overlapping the edges of the tape. The overlapping edges are in the gluing device 80 with glue to form a longitudinal seam that "

is sealed in the sealing device SD. The strand body passes through two opposing tools or press rollers 11A and 11B after exiting the strand former. The upper press roller 11A is provided with two peripheral pressure or Press projections 110 and 11D and the lower press roller 11B is provided with two corresponding projections 11B and 11F Mistake.
