The arrangement for forming the cigars and cigarillos is also mounted on the frame 2. On a bracket 3D connecting the two-frame parts 3 and is secured by two bearings (not shown) the supply-spool 32. On this spool is wound the tobacco covering strip 3d and the auxiliary strip 35 preferably made of paper. The two strips 3d and 35 run between two guide pulleys 35 and si@ and across an adhesive device i2 mounted on the bracket 35. The covering strip 34 and the auxiliary strip 35 then move together over pulley 134i mounted on a shaft pivotally secured in the plate 'l of the frame 2. The two strips 3d and 36 then move beneath the tobacco charge coming from the bridge 25, and the strips and the tobacco filling then move together into the inlet-funnel 28. On this part of the plate 'i is guided a shaping-belt i5 running over the pulleys fili, 55, and 52 and driven by the driving roller 5d, as is shown more in detail in Figs. 4 and 5. The driving roller 5d may be driven by convenient means as an electric motor or the like (not shown). The shaping belt l5 takes up the tobacco charge lying on the two strips 3d and 35 and pulls the strips and the charge through the inlet-funnel 28 to the shaping channel 55. This channel is overlapped by the shaping members 55 and ii@ (see Fig. 5) rounded on their inlet-portions 5?. and Gil. These shaping members 53 and 5l) are secured by bolts 53 and 55 or the like to the channel 55. In Fig. 'Z there is shown a section taken on line VII-VII of Fig. 4i illustrating the overlapping of the two shaping members.

After leaving the shaping members 5t and 50 the combination of tobacco charge 23, covering strip 34, auxiliary strip 35, and shaping belt 45 moves through the outlet-finger 55 to the seam smoothing iron 5S which may be electrically heated. The outlet finger 55 is shown more in detail in Figs. l, 5 and 8 and has a bridge part 51 secured by bolts 59 to the shaping channel 55. The smoothing iron 56 is shown more in detail in Fig. 9 and may be provided with a smoothing edge 'll heated by a device 'i3 in convenient manner, such as by electrically energized windings or the like (not shown). Having passed the smoothing iron S8 the auxiliary strip 36 and the shaping `belt 4S are separated from the tobacco charge surrounded by the covering strip 35. The auxiliary strip 36 is then wound on the storage spool it positioned on the frame part 5 in any convenient manner. The shaping belt 4S returns over the driving roller 54 and is ready for further use.

The tobacco charge 23 surrounded by the f sealed covering strip 3d moves to a cutting device generally marked by the reference number l2 shown more in detail in Fig. l0. The cutting device comprises an eccentric knife 14 pivotally mounted on a shaft 'l5 secured in bearings conveniently xed in the casing 18 shown in section in Fig. 1G. The shaft is driven by convenient means, such as an electric motor or the like (not shown). The knife 14 moves into a slot 80 in a tube composed of the two portions 82 and 84. The tobacco charge 23 surrounded by the sealed covering strip 31E passing the tube 82, tf1 is cut by the knife 'M- and the cut portions thereof as cigars and cigarillas are pushed out onto a conveyor 85 arranged at the end of the machine. The cigars or the like may be transported through the conveyer 55 to a packing machine.

The operation of the machine described above is as follows:

The cut tobacco falls from the feeder 4 onto the conveyor 6 and is supplied to the chute 8. From the chute the cut tobacco slides onto the conveyer belt l2 guided in the U-shaped channel member I8. In this channel member lil and between the pressing wheels 22 and 24 and the pressing plate Z5 it is formed to a strand or rope which is forwarded by the conveyer belt I2.

On the storage spool 32 the tobacco strip 34 and the auxiliary strip 35 are wound so that the auxiliary strip which may be made of paper, lies beneath the corresponding portion of the tobacco strip 34. The width of the strips is such that the tobacco strip overlays the auxiliary strip on one side about 2 mm. The width of the tobacco strip is a little greater than the circumference of the cigar or like to be made. The guiding of the two strips is such that the pull exerted by the shaping belt i6 is always transmitted to the auxiliary strip 35, i. e. this strip lies on the guiding pulleys :ill and llt respectively.

Through the pulleys 3B, 49 the combination of the two strips 3, 35 moves to the adhesive device 42. The wheel 53 dipping into a container containing an adhesive material applies an adhesive seam to the edge of the tobacco strip 311 supported by the auxiliary strip 36.

The combination of the two strips 313i and 35 meets the tobacco charge coming from` pressing device 22, 24, 25 and running through the bridge 25 on the inlet-pulley its. The tobacco charge combined with the two strips enters the shaping channel 5G the raised sides of which bend the edges of the strips upwardly. The upwardly bent edges of the strips enter the shaping menibers 58 and 55. These overlapping members bend the strip edges one upon another. The holding together of the tobacco charge is insured by the inlet-funnel 28, as is shown in more detail in Fig. 5. The overlapping of the strip edges is illustrated in Fig. *l from which it may be seen that one edge of the strips is beneath the member 55 while the other edge is between the members 58 and 50. The strip edges lying between the members 58, 55 are correctly registered and the underlying tobacco strip on its inner side is provided with the adhesive seam. The other strip edges underlying the member Eil are not correctly registered because the auxiliary strip edge is narrow relative to the tobacco strip. In leaving the shaping members 58, 55 the tobacco strip edge provided with adhesive seam therefore lies directly on the other tobacco strip edge. ln this condition the tobacco charge surrounded by the two strips enters the seam smoothing iron 58 which effects the sealing of the longitudinal seam. After sealing the tobacco strip 34, the shaping belt 45, and the auxiliary strip 35 pass over the pulley 52. Now the length of the tobacco strand moves to the cutting device 'i2 and is out oii and finally removed by the conveyer as finished cigars and cigarillas. The cut off cigars, cigarillas, stumps or the like can also be further processed, as for example, 4they may be provided and shaped with a wrapping. it is also possible to lead the uncut length further and enclose it with a wrapping strip in a like or similarly con structed machine before cutting up.

From Fig. 1 it is to be observed that all posin tions of change of direction through which the covering strip and auxiliary strip pass together are so disposed that the auxiliary strip traverses the shorter path, that is to say, lies on the inside. This arrangement offers substantial advantages and is distinguished from the path of the paper strip in the case of cigarette machines.

While we have described and shown in the foregoing specification and drawings a preferred embodiment of the invention, it will be understood that many changes and alterations may be effected without departing the scope of the following claims. For instance, all moving parts, as conveyer 6, driving roller 20, driving roller 54, cutting knife T4, spool 10, and conveyer 86 may be driven by a common driving device as an electric motor or they may be driven by separate motors suitably synchronized.
