Line guiding system for at least one supply line which can be coiled and uncoiled and rotary guide therefor

A rotary guide for a line guiding system, comprising:

• at least one line, which is guided in the rotary guide from a first point to a second point which is relatively rotatable about an axis of rotation relative to the first point, wherein the at least one line has a helical guiding course in the rotary guide with one or more first helical layers, in which the at least one line is wound about the axis of rotation in a first direction, one or more second helical layers, in which the at least one line is wound about the axis of rotation in a second direction opposite the first direction, and a return curve which connects the first and second helical layers and in which the at least one line is turned;
• wherein the rotary guide has an outer tubular support sleeve for supporting the first and second helical layers radially outwards and an inner tubular support sleeve for supporting the first and second helical layers radially inwards, and
• wherein the outer tubular support sleeve and the inner tubular support sleeve are rotatable such that the outer tubular support sleeve and the inner tubular support sleeve are decoupled from the rotation of the second point.
