Air manifold

The present invention is generally related to two piece can making equipment, and more specifically related to an air manifold for can making equipment, and a necking machine incorporating the air manifold. The invention includes an air manifold comprising at least one port adapted for receiving high pressure air from a compressor, at least one port adapted for receiving low pressure air from a compressor, at least one port adapted for bleeding high pressure air from a container, at least one port adapted for reusing high pressure bleed air. The port for reusing high pressure air receiving high pressure air from the port adapted for bleeding high pressure air. The air manifold also includes at least one port adapted for bleeding low pressure air from a container and at least one port adapted for reusing low pressure bleed air. The port for reusing low pressure air receiving low pressure air from the port adapted for bleeding low pressure air. The present invention also includes an air distribution system and a necking machine which include the manifold as well as a method of necking a can.
