摘要:
In a lifting drive for a friction roller which can reciprocally move in an axial direction, an adjustment can be carried out using simple means during operation. To this end, the friction roller is connected in an articulated manner in the area of the rotational axis thereof to a first end of a connecting rod. The second end of the connecting rod is connected in an articulated manner to the peripheral area of a rotatable lever which can be driven. A rotational axis of the shaft of the lever is arranged such that it forms an angle with regard to the rotational axis of the friction roller.
