摘要

The transport device has bodies (12,14) with a passage which is supplied by an air supply area (46). A retaining surface (40) is formed at an end of the body facing a workpiece and a circular swirl chamber (68) is provided inward by the retaining surface. A discharge opening (64) is connected with the chamfer surface (60) of the swirl chamber and swirl chamber is connected with passage in order to guide air outward into swirl chamber. A projection (54) is provided in the center of the swirl chamber and the diameter of the projection is reduced gradually towards work piece.
