<p>Automatic blank-mold sooting device in the glass making industry, adapted to deposit a lubricating/detaching layer on the internal walls of said mold, said deposit being substantially made of carbon black obtained from acetylene cracking process. Plugging means (6, 7, 8, 9) are provided to disengage the bottom (10) of said blank mold (1) during a blank mold sooting process, whereby said lubricating/detaching layer can be deposited substantially in a uniform way on all portions of said blank mold internal walls, allowing that a glass gob (3) can freely flow along said internal walls. <IMAGE></p> |
