In order to attach mouthpieces to cigarettes, cigarillos or the like by means of connecting leaves, devices are known, among other things, in which the connecting leaves are put around _; i around the axially parallel troughs of a conveyor, z. B. a drum, lying cigar mouthpiece groups by their rotary movement in the troughs by the groups are brought up to an opposing surface that is either fixed or at a speed other than the conveying speed, z. B. the trough drum is moved. The rolling movement caused by this causes the glued connecting leaflets to roll around in one go.

From these known devices, the invention differs in that to achieve the rotational movement of the Zigaxette mouthpiece groups between two coaxially next to each other arranged trough drums coaxially with these a further a cylindrical outer surface ao having the diameter of the trough bottom, with different from the trough drums Circumferential speed rotating drum and the distance of the cigarette thickness in known Way a part of the drum circumference concentrically surrounding movable counter surface is arranged.

This results in a safe and, moreover, controllable rotary movement of the cigarette mouthpiece groups as well as the advantage of smaller dimensions of the devices achieved.

The device is shown schematically in the drawing using an example, namely shows Fig. Ι a transverse and

Fig. 2 is a longitudinal section through the drum-like conveyor, while the

Fig. 3 and 4 show partial cross-sections along the lines CD and AB in Fig. 2 on an enlarged scale and

Fig. 5 a development of part of the drum circumference in plan view.

With ι and 2 (see Fig. 2) two seated on a common drive shaft 3 coaxial troughed drums are referred to, which are used in a known manner for transverse axial transport of the cigarette mouthpiece groups and are driven, for example, via spur gears 4. On the periphery of the hollow drums axially parallel depressions i _a or 2 _a are provided which are separated from one another by webs or _i 2 ₆ (see. Also Fig. 3 and 4).

As can be seen in FIGS. 2 and 5, the length of the troughs i _H and 2 _a corresponds to the width of the drums; they are used to hold cigarettes Z ₁ and Z ₂ . In contrast, the webs I ₆ and 2 _{& are extended} beyond the dimension of the drum widths in order to be able to serve to guide the mouthpieces M.

Underneath the facing cigarette ends protruding beyond the drum width and the mouthpieces lying in between, there is between the two coaxially juxtaposed trough drums 1 and 2 coaxially with these another drum 5, which has a cylindrical outer surface with the diameter of the trough base and which is provided on the circumference with an elastic coating 5 _a and is easily rotatable on the hubs of drums 1 and 2. The drum 5 rotates at a circumferential speed that is different from that of the troughed drums 1 and 2. In the embodiment shown, the rotating drum 5 is driven from the outside, for example by means of a friction disk 6, the lining 6 _{a of} which rests on the lining 5 _{a of} the drum 5 between the ends of the drum webs I ₆ and 2 _b. The rotating drum 5 can also be driven from the inside, for example by the drive shaft via a planetary or other gear with internal teeth. In this case, the webs i _b and 2 _& do not need to leave a gap free, but can extend over the entire width of the drum 5 to guide the mouthpieces.

From the outside, an endlessly revolving belt 7 is brought up to the circumference of the troughed drums ι and 2 and the rotating drum 5 in between, which wraps around the stated circumference at an appropriate angle and in the same direction as the direction of rotation or conveying of the troughed drums 1 and 2, but with at a higher speed in the direction of arrow p . In contrast, the counter-rotating speed of the drums 5, 5 _{a is} lower.

When the connecting leaflets 8 are fed to the Stellet (Fig. Ι and 3), they are perfectly and easily rolled around the mouthpieces M and the abutting cigarette ends on the way from 5 to S ₁ , the drum 5, 5 _ß rotates in the opposite direction in the direction of 5 '.
