Abstract: An air assisted sliding device has a pallet supported on a base. The pallet has a recess provided on the periphery of its bottom surface in which a flexible tubular sealing member is mounted. The sealing member has a memory normally contracting it so as to be flat. An air passage communicates with the interior of the flexible sealing member so that compressed air can be fed to it. A groove is evenly provided on the bottom surface of the pallet within the bounds of the recess and a separate air passage for feeding compressed air or vacuum air is communicated with the groove so that the pallet may be provided with an air film of compressed air or may be stopped and a vacuum applied to attract the pallet to the base at a predetermined position on the base. A timing belt drive or an electromagnetic motor is used.

Abstract: A fixed ceiling is provided from which depends a carrier block which is movable forward, rearward, rightward and leftward. An exhaust port is provided on the upper surface of the carrier block and a seal member is provided on the surface of the carrier block about its periphery so that a vacuum can be created on the upper surface of the carrier block and the carrier block may be freely sucked to the fixed ceiling. Vertically movable fitting parts for a plurality of tools are provided below the carrier block.
