- an intermediate wheel can be used, which is interposed between the toothed wheel fixed to the drive shaft and the web wheel in order, for example, to transmit a required direction of rotation to the web wheel.
- the drive shaft may have a further drive wheel, which is in drive connection with a drive element of the main drive, which is also in drive connection with the gear stage with non-circular gears.
- the drive element of the main drive consists of a rotatably mounted in the machine frame gear, which is driven by other means of a central drive motor (main drive), wherein the axis of rotation of the gear is coaxial with the input shaft of the gear stage with the non-circular gears and the further drive wheel of the drive shaft is designed as a gear which is in drive connection with the gear of the main drive.
- main drive central drive motor
- the gear of the main drive is mounted directly on the input shaft of the gear stage with the non-circular gears.
- the input shaft of the gear stage is connected via releasable fasteners rotatably connected to the gear of the main drive.
- the fastening means can be provided with guides which allow an adjustment of the angle of rotation between the input shaft and the gear of the main drive with dissolved fasteners.
- the drive of the pliers is also coupled to the main drive.
- a displacement of the movement cycle of the Abreisswalzen can alternatively be achieved by the fact that the gear on the drive shaft via
- Fastener is releasably secured and the angular position between the
- Angular position via adjusting means (12, 14) to provide adjustable.

- the bearing 6 is supported on a central shaft 5, which is rotatably mounted in the present case on the bearings 10, 11 in the machine frame MS.
- On the other side of the web 2 is rotatably mounted on a bearing 7.
- the bearing 7 is supported on a hollow shaft 9, which is supported on the schematically indicated bearings 8 on the already cited shaft 5.
- the circumferential web 2 is provided with a web wheel 3, which is fixedly connected to the web. Another alternative is shown in an enlarged view in Fig. 3, wherein the web wheel 3 is provided with a superior base body 12.
- longitudinal slots 14 are provided on both sides whose longitudinal extent in the circumferential direction of the web 2 extends.
- these slots 14 in each case one or more screws 13, which are fastened in threaded bores 15 of the web 2.
- the web wheel 3 is fixed relative to the web 2.
- the web wheel can be rotated relative to the web by an amount in the circumferential direction, whereby its angular position relative to the web changed.
- the intermediate wheel 37 is mounted rotatably in the machine frame via its axis 36 in bearings L.
- the gear Z is rotatably mounted on a, mounted on bearings L in the machine frame drive shaft 20.
- a further gear 16 is mounted on the drive shaft 20, which is in drive connection with a gear 18 of a main drive HA.
- gear 19 which is connected via a shaft 38 to a central gear unit G in drive connection.
- the drive of the transmission unit G is carried out by a motor M via the drive connection 40 shown schematically.
- the flange is secured by a screw 27 indicated schematically. Via the screw connection 24 shown schematically, both flanges 23, 25 are fixed against each other. Thus, the gear Z is fixed in rotation on the shaft 20. As can be seen in FIG. 5 (view Y according to FIG. 1), a slot 30 is provided in the region of the screw connection 24, via which a change in the angular position between the toothed wheel Z and the shaft 20 can be carried out after the threaded connection 24 has been released. Even with this device, a shift of the Abreisszeitifiess the Abreisswalzen to the position of the nipper unit is possible.
- the sun gear S2 of the second gear stage G2 of the differential gear 1 is fixedly connected to a rotatably mounted hollow shaft 9, which, as already described, is supported on the rotatably mounted shaft 5 via the bearings 8. With the sun gear S2 are distributed on its circumference and stored in the web 2 planet gears U4 to U6 in drive connection.
- the planetary gears U4 to U6 are connected via the shafts 33,34,35 with the planetary gears U1 to U3.
- a gear Z1 is fixed, which in turn is in drive connection with the gears Z2 and Z3.
- the gears Z2, Z3 are connected via the shafts W1, W2 with the Abwalwalzen A1, A2.
- the Abreisswalzen A1, A2, and the waves W1, W2 are mounted on the schematically indicated bearings L in the machine frame MS.
- the shaft 5, on which the sun gear S1 is mounted, is at the same time the output shaft of a gear stage G3, which is connected upstream of the differential gear 1, with non-circular gears 43, 44 which mesh with one another within a housing 4.
- the non-circular gear 43 is rotatably mounted on the shaft 5.
- the non-circular gear 42 is rotatably mounted on a shaft 44, on softer at its other end a flange 50 is fixed, via which it is fixedly connected via screws 51 to the gear 18 of the main drive HA.
- the shaft 44 is, as indicated schematically, rotatably supported by the bearing 45 in the machine frame MS. Of course, even more bearings can be provided.
- bearing points for the shafts 5 and 44 are present within the housing 4, which was indicated schematically in Figure 1.
- the screws 51 protrude through slots 53 of the flange 50 (see FIG. 4 of view A of FIG. 1) and are received in threaded bores 55 provided in the gear 18.
- the gear 18 is rotatably supported via the bearing Lx in the machine frame via the axis 48.
- the axes of rotation of the shaft 44 and the axis 48 are parallel to each other axially.
- the uniform drive of the Gear 18 takes place, as already described, via the gear 19, via the shaft
- an adjusting device can be provided for adjusting the movement curve of FIG. 3 and FIG. 5
- Flange 50 are rotated over the slots 53 by a certain angle of rotation to be fixed in this new position again by tightening the screws 51.
- Between the flange and the gear 18 markings may be provided (not shown) via which a corresponding adjustment can be determined. With this adjustment, the movement curve of the Abreiszylinder against the movement curve of the nipper unit, which also from the
- Main drive HA is driven to be moved.
- Such a movement curve of the Abreisswalzen is z. B. shown in Fig. 6, which represents the course of a comb play KS. In the first area lead the
- A2 be varied.
- Gear 43 implemented in the gear stage G3 in a non-uniform rotational movement, which is transmitted via the shaft 5 to the sun gear S1.
- the gear Z transmits this uniform rotational movement about the intermediate
- Planet wheels U1 to U3 are moved around the sun gear S1. This creates a resulting non-uniform rotational movement of the planet gears 111 to U3, which transmit them to the planetary gears U4 connected to them U6.
- the planet gears U4 to U6 transmit the thus generated non-uniform movement (pilgrim step movement) on the sun gear S2, which transmits them via the shaft 9 and the gear Z1 to the gears Z2 and Z3 of the Abreisswalzen.
- FIG. 7 shows the course of the movement curve (FIG. 6) of the tear-off rollers such that the drive load or the torques to be applied can be considerably reduced, as shown schematically in FIG Diagram of Fig. 7 is shown.
- the course of the torques M (Nm) is shown by a comb play, which is divided into 40 index.
- the drawn with a solid line curve shows the course of the existing torques of previous drive solutions.
- the dashed curve shows the torque curve, which was achieved under the claim claimed in the invention using the drive unit with non-circular gears.
- the torque loads on the positive, as well as on the negative side can be significantly reduced. This results in a lower load on the drive elements and also allows an increase in Kammspieliereiere without overloading of the mechanical elements.
