Zusammenfassung:	A sequencing manifold for selectively drawing air from a plurality of vacuum channels, comprises, a fixed element having an outer surface and an internal cylinder, the fixed element further including a plurality of holes passing from the outer surface to the internal cylinder, the plurality of holes communicating with the plurality of vacuum channels. A piston is movably disposed within the internal cylinder and includes a hollow portion in communication with a device for drawing air. The piston is movable within the internal cylinder to align the hollow portion with a predetermined number of the plurality of holes for selectively drawing air from the predetermined number of the plurality of holes.
