The machine shown in the accompanying drawings, sheets I to III, in FIGS. I to 16 serves to extract the tobacco leaves in a completely mechanical and automatic manner to manufacture finished wraps. This processing takes place in a continuous process of tobacco does not only happen in a special way, but also with use very special facilities and mechanisms. The whole process, as it takes place in the action of the machine, is following.

. The undivided tobacco leaves are poured into a filling funnel A , the bottom of which is formed by the rollers B fitted with knives and rotating at different speeds, which rollers not only bring the crushed tobacco down onto the discharge surface α , but also if more tobacco is crushed will, than should or can be processed by the machine, drive this "too much" of tobacco back up into the hull of the hopper, for which purpose the knife b of the roller B are above the discharge surface α to close the tobacco accumulating there grab it and bring it back upstairs. From the discharge surface α the tobacco arrives in a narrow conveying channel C formed by endless towels c and d , the walls of which are formed by the towels c and d driven by means of the rollers D and E and set in progressive motion.

The tobacco received in the conveying channel C enters a slide F, which is movable in the horizontal direction and is driven by the mechanisms R consisting of parts G and H. This slide slides on the plate e and is provided with the opening / necessary to accommodate the amount of tobacco required to produce a roll. This opening is made at the appropriate moment via a winding device J ; at the same time, the tobacco is pressed into the wrapping cloth g by a special pressing die K (see FIG. 2). This process takes place through the cooperation of the following parts. Before the slide F is the movable up and down, by means of lever O h with nose and disc pins i and k driven stamp K. This stamp makes two downward movements in a work machine, of which the one serves to on the drum J lying wrapping cloth !, g to form a receiving pit / (see Fig. 1), while during the second downward movement the tobacco located in the slide F, which has meanwhile moved forward, is pressed into the pit / the wrapping cloth g (see Fig. 2) . After the tobacco required for a wrap BEZW in the wrap. whose pit / is brought, the latter begins to come into effect and to roll the roll tightly, which happens because the cloth drum J is rotated in the direction of the arrow (see FIG. 3), which not only results in a longer turning and rolling time for the Formation of the roll occurs because the arrangement of the rolls m and η conducting the wrapping cloth g causes this, but at the same time also; after the winding roll time has elapsed, the

finished wrap is not only brought out of the wrapping cloth (see Fig. 4), but also a pressing of the finished roll into a roll form is effected.

The following device is used to bring about the last-mentioned process: The hollow cloth drum / is provided with a special prefs and push-in mechanism, which consists of the pusher 0, which is driven by the crank ρ and rod q , and by means of the rack L, the tie rods rr and the crank M located on the main axis s is moved by means of the wheel t from the shaft u laid through the roll journal means. This Prefsmechanismus comes into effect when the cloth drum J is in the rest position (see Fig. 1), in which it is held by the pin ν , which, against its spring pressure, from the inclined surface w to the rack L in the corresponding period to hold the drum J in place . The pusher 0 is moved downwards and the roll previously placed in the pit / drum / and held by the wall χ, which is resilient according to the winding thickness, is introduced into the roll form N and firmly pressed in. After this process has taken place, an overall working process of the machine is completed and the game for the formation of the next lap begins anew.

It should be emphasized, however, that the swaddling cloth resp. the Ausstofsmechanismus the same and the forming board N for receiving the finished winding are in special cooperation (see. Fig. 5 to 8). The molding board must. be shifted after completion of each winding, which is done with the help of a special Klinkwerk. This pawl consists of two pawls y and \, of which ς falls into the tip hole of shape N and determines the degree of advancement, while y engages on the open side of the mold (the burning side of the cigar) and takes care of the advancement. The movement of the former latch% is achieved by a nose α ¹ of the standing wave P (s. Also FIG. 6 and 8) which presses the pawl \ influencing resilient lever b ¹ in the moment and the pawl · {triggers where the advancement begins, but immediately releases the same and the pawl again, so that the latter, sliding on the mold, falls into the next point hole, while the pawl y is moved by the eccentric with the angle lever c ¹ and the rod d ⁱ which latter acts on the spring e ¹ , which is attached to the slide Q with the pawl _y at the same time, with spring e ¹ absorbing the excess force of the thrust, which pawl y does not allow because it falls into the next tip hole. These parts cooperate with the drum J in such a way that the displacement of the forming board N takes place during the movement of the wrapping drum, but a correct and reliable shutdown of the forming board takes place in good time in such a way that the ejector 0 of the wrapping drum J is exactly above a wrapping trough / ^{: of} the shape board is located.

Arrangements have also been made so that the corresponding parts can be adjusted according to the size and shape of the coils. The feed device R (see Figs. 12 to 15) can be adjusted by means of a special braking device 5 on the drive rollers D and E for the feed cloth, whereby the speed of the cloths c and d (see Fig. I) can be changed can, in that the brakes S are fixed on the rollers JD and E , which are loosely seated on the axes g ¹ and h ^l , and brake more or less on the former by tightening the screw i ¹ , Fig. 12, so that a larger or smaller one The feed rollers D and E are required to be taken along.

As soon as the mold board N is filled, the main drive shaft s is triggered and the whole machine comes to a standstill, so that the filled mold board can be removed and a new one inserted, whereupon the new series of operations can be started.

The drive of the machine is done from the W ^T elle Ar ^1, which by means of hand or power unit can be moved. From shaft k ^1, the cutting rollers B are provided by means of the cord pulleys T and ' U and wheels VWX, and by means of the standing shaft P, the bevel gears Y and Z and the partially toothed wheel A ^1, the sewer cloth rollers D and E, and furthermore by the crank pins Z ¹ and the curved slots in FIG. ¹ on the sliding jaws H , the disk G and the indenter K through the nose lever O influenced by the two pins i and k , the spring n ¹ pulls the punch K back into its original position. The sewer cloth roller D is moved by the crank disks o ¹ and p ¹ with pull rod q ^l , which is guided on the pin r ¹ in the slot for correct turning. The wrapping drum J and its ejection mechanism are driven by the crank disk M with the lever s ¹ and the tie rods r and r through the rack L , which is partly toothless in order to achieve the necessary standstill of the wrapping drum. The gear of the mold plate N is by the action of the eccentric B ¹ and the nose α ¹ on the shaft P.

moves, whereas the entire machine is stopped by the action of the stop i ^{1 located} on the ratchet wheel C} on the triggering device D ¹ , consisting of the dome v ¹ moved by the return rod u ¹ . This triggering device can also be moved by hand at any time. The eccentric E ¹ moves the pawl w ¹ for the counting wheel C \ which triggers when the winding form is filled.

The whole machine works easily, quickly and reliably and can be manufactured of wraps of all types and sizes, as well as for processing various types of tobacco use.
