Conversion. Beverage containers to aviation oxygen cylinders. The first step in the manufacture of high-altitude-flying shatterproof oxygen cylinders in the metal department of a large rubber factory is the forming or stamping of the shell. Stainless steel sheets are blanked or cut into discs(left foreground). Before stamping, these discs are drawn through rolls where a drawing compound is added to both sides to facilitate the forming of the shell. The 750-ton toggle press, shown above, forms a half cylinder in one powerful stroke. Once the half cylinder is formed, it is trimmed and the value-fitting hole is punched into the spherical dome. A cleaning operation later removes the drawing compound. The cylinder halves are now ready for the various welding operations. Firestone, Akron, Ohio
