Abstract
A cooling air system for a glassware forming machine which has a plurality of individual forming units, with each unit having a plurality of different mechanisms to be cooled and each unit having the same mechanisms. The system includes a manifold associated with each mechanism, an inlet line connecting each manifold to a source of cooling air, and a pilot operated regulator in each inlet line. The manifold is connected to its associated members in all forming units. Manually operated means are associated with each of the pressure regulators for individually controlling the flow of pilot air to each pressure regulator.
