It is known to manufacture cigar fillers by passing a roller over a rolling-table at both ends of which the filling cloth is attached, the latter being preferably under the influence of a tensioning The filling cloth is passed over the roller in such manner that a loop is formed behind the roller, in which loop the filler is formed by rolling.

It is then advisable immediately to give the filler the shape or approximately the shape of the finished cigar. In order to render this possible it has already been proposed that the filler roller, which cooperates with the rolling-table, should be given a corresponding shape. This, however, involves the drawback that owing to the special shape of the roller the filler-cloth, which is in the form of a band, is subjected laterally to varying tensile stresses which cause the formation of creases and the rapid wearing'out of the fillercloth. 7 I

In order to avoid this drawback, a countershaped compensating roller is, according to this invention, fitted in front of the specially shaped filler-roller, so that the uneven stresses of the filler-cloth are balanced.

The invention is illustrated in the annexed drawing, in which:-

Figs. 1 and 2 show one of the earlier forms of construction without a compensating roller, in vertical longitudinal section on the line 1-1 of Fig. 2, and in plan respectively.

Figs. 3 and 4 show a roller device provided with a compensating roller according to this invention, invertical longitudinal section on the line 3-3 of Fig. 4, and in plan respectively.

The filler is formed in known manner on a table 1, at the ends of which, at 2 and 3, the fillercloth, indicated by chain dot lines, is attached. The filler cloth is tensioned by means of a tension roller 5 which is mounted on a lever 6, the latter being pivotally mounted at 7 on the table 1 and with which engages a spring 8 that tends to displace the lever so as to increase the tension of the cloth.

At the beginning of the operation the cloth is on the table in the position indicated by the dotted lines. Then the quantity of tobacco necessary for a filler is emptied into a trough-like fold in the filler-cloth, the fold being formed by a recess 1 in the table 1. The axles 9' of the roller 9, which is shaped as shown in Fig. 2, rest in the bearings 10, and the roller is then moved forward in the guides running along the edge of the table in the direction indicated by the arrow'in Fig. 1. As soon as the roller 9 arrives within the range of the recess 1', the tobacco is carried along with it in a loop which is formed behind the roller 9, whereupon the tobacco is rolled thus forming the filler W. As the roller is suitably shaped the ends of the rotating member are given the pointed shape peculiar to cigars. As can be seen particularly from Fig. 2, this subjects the filler cloth to uneven tensile stress, making the undesirable formation of creases unavoidable.

In the mode of construction shown in Figs. 3 and 4,-this uneven stressing of the rolling cloth 4 is balanced by the provision of further bearings 10 for the axles 11 of the counter-shaped roller 11. As may be seen particularly in Fig. 4, this countershaped roller is thickened where the roller 9 is tapered and vice versa, so that at the spot where the rolling cloth is subjected to its greatest stress by the thickened portion of the roller 9, compensation is provided by the taper of the roller 11.

Having thus described the nature of the'said invent-ion and the best means I know of carrying the same into practical effect, I claim:--

1. A machine for shaping cigar fillers comprising a rolling table, a roller adapted to be displaced along the surface of said table and shaped inconformity with the desired filler, a filler cloth passing over said'roller, and a second roller located in front of said first named roller shaped in reverse of the first named roller as to balance the uneven stressing of the filler cloth caused by the first named roller and over which said cloth is also adapted to pass.

2. A machine for shaping cigar fillers comprising a rolling table, a roller adapted to be displaced along the surface of said table and shaped in conformity with the desired filler, .a filler cloth passing over said roller and a counter shaped roller located in front of said first-named roller, said counter-shaped roller having a thickened portion corresponding in position to the tapered portion of the first-named roller and a reduced portion corresponding in position. to the thickened portion of the first named roller.

3. In a cigar filler shaping machine having a roller shaped in conformity with the desired filler and a filler band adapted to pass over said roller, means for compensating the stresses upon said filler band comprising a second roller shaped in reverse of thefirst named roller over whichsaid band is also adapted to pass.

4. A machine for shaping cigar fillers comprising a. rolling table, a roller adapted to be displaced along the surface'of said table and shaped in conformity with the desired filler, a filler band 1 filler, a filler band cooperating with said roller, secondary means cooperating with said filler band and shaped in reverse of said first named roller so as to balance the uneven stressing on said filler bandrcaused by the first named roller.
