Zusammenfassung:	A sequencing manifold for selectively drawing air from a plurality of vacuum channels (152), comprises, a fixed element (700) having an outer surface (720) and an internal cylinder (702), the fixed element further including a plurality of holes (722) passing from the outer surface to the internal cylinder, the plurality of holes communicating with the plurality of vacuum channels. A piston (750) is movably disposed within the internal cylinder and includes a hollow portion (760) in communication with a device for drawing air (120). 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.
