Device for guiding tubes or cables

Claim 1

An assembly for guiding cables between a stationary part and rotating part following movements of a bidirectionally rotatable body, comprising a plurality of cables arranged adjacent to each other in the direction of an axis of rotation and in a U-loop running concentrically around the axis of rotation, wherein strand ends belonging to different loop strands are connected with the stationary part and the rotating part, respectively, wherein the cables are distributed between two loops, running in opposite directions and located at opposite sides of the axis of rotation, wherein guiding rollers are arranged concentrically around the axis of rotation of the rotatable body in a ring arrangement, the axes of rotation of these guiding rollers being parallel to the axis of rotation of the rotatable body; the guiding rollers being arranged between the loop strands of the loops and being driven by rotatory movements of the rotating body in that the circumferential speed of the guiding rollers equals the speed at which the loop strands unwind on the rotatable body and the guiding rollers, and wherein the guiding rollers are kept displaceable and rotatable at each longitudinal axial end in a guiding groove of a guiding plate.
