PATENT OFFICE.

In cutting devices for cutting a continuously moving cigarette rod In individual cigarettes there has been a swinging movement as well as that in the direction of the Required longitudinal movement of the knife through thumb and cam disks, which with a single rotation of the same supporting shaft only a single movement of the knife in the mentioned directions. For this reason they are suitable said devices only for cutting up something moving at moderate speed Cigarette rods. Should now in order to increase the efficiency of the cutting device the cigarette rod to be cut must be moved very quickly Use of the devices marked above that cause the knife to move Slices, in order to be able to make the cut in time, in such a fast way Circulation are displaced that the device would be unusable in a short time.

The invention now has a cutting device for cutting up a fast moving vehicle Cigarette rods into individual cigarettes to the subject in which the said Evil is eliminated. For this purpose, the present device is based on a rotatable shaft attached a disc, which on its surface with a larger Number of equally distributed lifting thumbs is occupied, which when the shaft rotates In order of the rotating knife, the one required for each cut. Swinging movement impart. A second disk is attached to the said shaft, against its inner one.

ring-shaped end face a sliding roller seated on the knife carriage by a spring is pressed. In the face of the disc is one of the number of thumbs on the first-mentioned disk corresponding number of wells arranged in such a way that, if one of the thumbs on the one disk the swinging motion of the rotating knife causes the roller, the knife carriage in the other, also rotating disc one of the aforementioned indentations is found, which enables the spring to operate during the cutting action of the knife - to achieve a straight cut with the Strange moved. 'By re-emergence of the roll from the relevant depression the knife that has come out of the line by itself is used to execute the next one Cut back. Due to the multiple arrangement of the thumbs on one and the other Depressions on the other disk make it possible for the shaft carrying these disks a slow orbital movement, whereas the cigarette rod moves quickly to be able to give without having to fear that this will result in work disturbances. Of course, the speed of rotation of the disk support shaft must correspond to the speed of movement ' of the cigarette rod.

An exemplary embodiment of the new cutting device is shown in FIG Fig. Ι shown in front view and in Fig. 2 in plan view.

In the two suitably fastened bearing parts α α the two rods cd connected to one another by transverse pieces bb are connected.

Claims (2)

slidably mounted. The two bearing arms ee , which are connected by a web and in which the cutter shaft f is mounted, sit rotatably on the rod d. The circular knife h is exchangeably attached to this shaft, which is to be set in rotation by a cord pulley g. The latter rests against the counter-knife i, which is fixedly attached to an extension of the one crosspiece b and which at the same time forms a guide for the cigarette rod to be cut, which is moved in the direction of the arrow in FIG. 2. A two-armed lever k sits loosely rotatable on the rod d , one arm of which is connected to one of the bearing arms e, while the other lever arm carries a sliding roller /. Against this roller acts temporarily on its surrounding surface with lifting thumb m disk n, which is fixed on a shaft ο rotatably mounted in the bearing parts α α. On the shaft ο sits a second disk ρ with an annular face, in which a number of recesses q corresponding to the number of thumbs m on disk η is made. Against this end face, a d-fitting at the other end of the rod is pressed s Gleitröllchens resistant from one at the end of the rod r a d clamped helical spring. When the shaft ο is rotated in the arrow direction indicated in Fig. Ι the thumbs m in sequence against the roller / and thereby swing the knife h each time to cut the strand upwards, which position Fig. Ι shows in full lines. At the same time the knife is with its carriage in the direction of cd strand barrel by the spring r pushed forward by the rolls s in which the respectively associated recess acting thumb m q in the disk j? entry. As soon as the acting thumb m leaves the roller /, the lever k swings with the knife h by its own gravity or with the aid of a spring back into the rest position indicated by dash-dotted lines in FIG. due to the shape of the recess q pushes back the roller s and thus the carriage cd with the knife h and holds it back until the next recess q arrives. Depending on the distance between the thumbs m and indentations q from one another and the speed given to the shaft ο a considerable number of (cigarette rods can be cut to the desired length from a rapidly moving cigarette rod in a short time, which was not possible with the previous cutting devices. It should also be mentioned that the knife carriage can also be slidably mounted in prismatic guides. Furthermore, the thumbs m can also be arranged on the surface of the disk ρ , in which case only the roller / arm of the lever k needs to be directed towards the disk ρ , while the disk η is omitted. Finally, instead of the disk ρ acting against the knife carriage roller s, a rail which can be moved back and forth and provided with corresponding wedge surfaces or depressions can be used. Godfather nt-A ν Proverbs: ι. Device for cutting up a steadily moving cigarette rod, characterized in that, for the purpose of substantially reduced rotational movement of the drive devices moving the cutting knife, the revolving excavation disk (s) is provided with a number of excavation thumbs (m) , so that with a single revolution of the said disk a number of cuts corresponding to the number of thumbs is made, the cutting device being under spring pressure so that the latter comes into effect during the cutting action to move the cutting knife, which displacement is limited by indentations (q) in the rotating disc (p) , while the Elevations in the said disc bring about the return of the cutting knife to the starting position. 2. Device according to claim ι with means for longitudinal and transverse movement of the cutting knife to the cigarette rod by a single drive part, characterized in that the excavation thumb .to complete the cut and the depressions to limit the knife displacement are attached to one and the same disc, to which Purpose of the cutting movement mediating lever (k) is designed in a cranked form to rest against the excavation thumb. For this purpose ι sheet of drawings.
