The invention relates to a star wheel used for transporting articles in an arcuate path. The star wheel is provided with a vacuum apparatus to retain the articles within pockets of the star wheel as the wheel is rotated between a point where the articles are loaded onto the wheel and a point where they are removed. The hub of the star wheel functions as a plenum for low pressure, high flow vacuum, and short openings are provided between the plenum and the pockets. One of the walls of the hub is stationary and, at its periphery, it is positioned closed to but slightly spaced from the rim of the star wheel. A blocking surface is provided within the plenum spaced with a small gap from the inner end of some, but not all, of the short openings, so that vacuum is blocked from some positions of the pockets as they rotate. The apparatus avoids wear and friction, is able to transport irregular shaped articles, and is less costly to manufacture and use.
