Abstract
A device for winding up and unwinding an elongated flexible element having a free end and a spatially fixed end. The elongated flexible element is divided over its length at least into a use portion and a compensation portion, wherein the use portion has the free end and the compensation portion has the spatially fixed end. The device includes a rotatable drum configured on its circumference to wind up and unwind at least the use portion in a first winding plane, wherein the end of the compensation portion is spatially fixed relative to the drum. The elongated flexible element in the transition from the use portion to the compensation portion is fixed at a fastening point to the drum, and when the drum is rotated the compensation portion is coiled up and uncoiled in the form of at least one looped portion in a second winding plane.
