ABSTRACT:
An articulated vacuum arrangement. A plurality of vacuum fingers are pivotably coupled to a base member, each vacuum finger comprising an arm extending from the point of pivot to an orifice to the atmosphere, each arm defining an air passage channel. The base member includes, for each vacuum pad, an orifice. An airtight structure connects between each base member orifice and its associated vacuum pad arm. A structure is included for creating at selected ones of the vacuum fingers a reduced pressure relative to atmospheric pressure.
