<p>A parison is blown into a bottle in a mold at the blow station of an I.S. Machine. Pressurized air is supplied to the mold from a source (110) through a cooling tube (20) which will be displaced downwardly from an up position, where the parison will be blown into a bottle, to a down position following the formation of the bottle. The pressure of the air is decreased as the cooling tube is displaced from the up position to the down position by means of a pressure regulator (112) controlled by a control (114).</p> |
