Abstract
Multi-disc clutches are known which usually have a first clutch pack consisting of steel discs and a second clutch pack consisting of friction discs. A disc for a multi-disc clutch is proposed, which has a disc body. The disc body is in a form of an annular disc, and has a driver contour on its inner circumference and/or outer circumference for mounting the disc in a rotationally fixed manner. The disc body is formed by edgewise rolling on the inner circumference thereof.

A disk for a multiple disk clutch, comprising a disk body, the disk body being configured as an annular disk, and the disk body having, on an inner circumference, a driver contour for fixedly mounting the disk for conjoint rotation, wherein the disk body is formed from vertical edge-rolling on the inner circumference.
A method for producing a disk comprising:
- providing an elongate metal strip with a first and a second longitudinal edge;
- vertical edge-rolling the metal strip about a bending axis on one of the two longitudinal edges so as to form a disk body,
- forming an inner circumference of the disk body, which is defined by way of the longitudinal edge that is worked by way of vertical edge-rolling, and
- forming an outer circumference of the disk body, which is defined by way of the other longitudinal edge (12a, 12b).
