<p>The energy is supplied from a stationary point by a flexible cable connecting the supply point with the movable component. The cable forms a loop near the component path, consisting of two straight sections parallel to the path, and of a semicircular connecting section. A stationary horizontal gliding surface (26) is provided near the path (12) supporting the cable three sections (20, 22, 24). It is limited by two parallel vertical walls (28, 30) supporting the sides of the straight cable sections.</p> |
