A friction clutch for a driven element that is connected directly to a drive by means of a first friction-disk clutch and being capable of being matched to the speed of the drive. When the first friction-disk clutch is disengaged, the drive of the driven element is adjusted to a relatively low take-up speed by means of an eddy-current clutch which can be engaged by means of a second friction-disk clutch. The driven element is arranged on a shaft or axle, so that, when the first and second friction clutches are disengaged, the drive of the driven element can be adjusted to a further take-up speed by means of the friction of a roller bearing. The eddy-current clutch includes an eddy-current part and a permanent magnet part which can be moved relative to the eddy-current part.
