<p>An automatic blank-mold sooting device for the glass-making industry and a sooting process using the device. The device is adapted to deposit a lubricating/detaching layer, which is made of carbon black obtained from an acetylene cracking process, on substantially all portions of the internal walls of the blank mold, enabling a glass gob to flow freely along the internal walls. The device has plugging means that is adapted to disengage the bottom of the blank mold during the blank mold sooting process. The plugging means has a collar, a ring and a plunger. Counter-blow air forms a parison when the plunger moves down. The plugging means is controlled by an invert that transfers the collar, ring and pre-formed parison from the blank mold to a blow mold, whereby the lubricating/detaching layer is deposited.</p> |
