Abstract
To provide for a tight seal upon selectively closing air exit openings from a compressed air-supplied tubular turning bar, a preferably endless tape or ribbon is moved within the bar, the ribbon having a slit of about half its length, for selectively positioning a solid portion or the slit opposite the air exit openings. The tape or ribbon can be positioned by a follower to which it is clamped, located on a rotatable spindle; or coupled to externally positionable deflection rollers. The excess air pressure within the interior of the tube seals the tape against the portions of the inner wall of the tube in the regions where the slit is absent.
