1. A winding device for winding a strand shaped winding material, the device comprising:
a winding disk onto which the strand shaped winding material is wound; and
a housing being arranged adjacent to the winding disk, wherein the winding disk is prevented from moving and rotating, by at least one magnetic holding device,
wherein the magnetic holding device comprises a first magnetic arrangement, which is torque proof connected with the housing and which has a north pole (N) and a south pole (S) and a second magnetic arrangement, which is torque proof connected with the winding disk and which is configured to have a north pole (N) and a south pole (S), wherein a gap is formed between the first magnetic arrangement and the second magnetic arrangement, wherein the first and second magnetic arrangements are magnetically coupled through the gap, wherein the strand shaped winding material is configured to pass through the gap, and wherein the first and second magnetic arrangements are arranged so that the south pole (S) of the first magnetic arrangement is arranged opposite to the north pole (N) of the second magnetic arrangement, wherein the north pole (N) of the first magnetic arrangement is arranged opposite to the south pole (S) of the second magnetic arrangement, and wherein the first or the second magnetic arrangement has at least two hard magnetic sections which are arranged in series.
