<p>The bearing (1) has a rotary disk (27) deflecting a turning rope that is overlapped over the rotary disk and immovably fastened on the rotary disk, where ends of the turning rope downwardly extend on two sides of the rotary disk, where the ends are directly or indirectly formed with lamellas (15). The rotary disk is provided with regions that exhibit different radii such that conveying speed of the turning rope is changed with respect to respective angle positions. Limb elements are articulatedly linked at ends of jacks (13).</p> |
