The apparatus includes a driven rotary member having a pluality of tubular arms extending from circumferentially spaced portions of the member. The ends of these arms pass through a portion of a receptacle in which the articles are stored and suction is set up on these arms at their ends as moved through the receptacle to attract articles thereto. An extracting mechansim is positioned in close proximity to the arc created by the ends of the tubular arms and applies a vacuum, greater than the vacuum applied by said tubular arms, to extract the articles from the tubular arms and transfer the articles to a point of deposit.
