Abstract: Disclosed for use in a line for manufacturing an article is a manufacturing work station which operates at subatmospheric conditions. The work station comprises a housing which includes a base plate having a recess at least as large as the article to be manufactured. The recess has a plurality of grooves formed in it. A spacer plate overlies the recess and has an aperture over each of the grooves in the base. A track insert plate generally of the same configuration as the spacer plate overlies said spacer plate and has a plurality of grooves therein which overlie each of said spacer apertures. A plurality of slanted holes are formed through the track insert plate and connect to the grooves in the track insert plate whereby when gas is applied through selected base plate grooves, the gas is transmitted through the slanted holes to move the article in the work station.
