A article-handling device includes a means of rotation, a vacuum conduit, and a first vacuum manifold, each rotatably mounted onto a stationary support shaft. The device further includes a second vacuum manifold affixed to the first vacuum manifold and a non-rotatable control valve which is operational synchronized with the rotation means to provide both vacuum pressure and atmospheric pressure independently to each of the first and second vacuum manifolds. Each of the vacuum manifolds comprises one or more tubular suction shafts each having a suction cup affixed thereto. The suction shafts of each vacuum manifold are spatially arranged such that at least a first suction shaft of the first vacuum manifold is substantially parallel to a first suction shaft of the second vacuum manifold thereby enabling the suction shafts to function as a paired unit. In this way, at least the first suction shaft of said first vacuum manifold and the first suction shaft of said second vacuum manifold are each independently adapted to attract and hold said article when the first and second vacuum manifolds are operationally connected with said vacuum pressure and release said article when the first and second vacuum manifolds are operationally connected with said atmosphere pressure.
