An apparatus for use in connection with a processing system on a surface having a contour, the apparatus comprising: an elongated flexible component having a first portion and a second portion; an actuatable component movable between a first position and a second position and having a first generally rigid portion and a second generally rigid portion; a first bracket having a first portion and a second portion spaced from the first portion of the first bracket, wherein the first portion of the actuatable component is connected to the first portion of the first bracket, and the first portion of the elongated flexible component is generally fixedly connected to the second portion of the first bracket for movement with and flexure with respect to the first bracket; a second bracket having a first portion and a second portion spaced from the first portion of the second bracket, wherein: the second portion of the actuatable component is connected to the first portion of the second bracket; the second portion of the elongated flexible component is generally fixedly connected to the second portion of the second bracket for movement with and flexure with respect to the second bracket; the actuatable component is configured to induce relative movement between the first bracket and the second bracket upon the actuatable component moving between the first position and the second position; and the elongated flexible component is configured to flex into a contour upon the relative movement between the first bracket and the second bracket; an actuator (260, 262c) that selectively moves the actuatable component between the first position and the second position; and a pressurized air bearing that is connected to the elongated flexible component and that facilitates movement of the elongated flexible component over the surface having the contour, wherein: the actuator (260, 262c) comprises a turnbuckle (260, 262c) threadingly connected to both the first portion and the second portion of the actuatable component; and the turnbuckle (260, 262c) is configured, upon selective rotation thereof, to simultaneously move the first portion of the actuatable component and the second portion of the actuatable component outwardly relative to the turnbuckle (260, 262c) or inwardly relative to the turnbuckle (260, 262c). an elongated flexible component having a first portion and a second portion;
