Abstract
A method for producing a hollow glass product by an I.S. machine, said method being a press-blow or blow-blow method and implementing at least one parison mould and one blow mould, said method comprising the lubrication of said parison mould, the lubrication comprising spraying via a nozzle, said nozzle being carried by the arm of a mobile robot movable along the parison mould side of the I.S. machine, characterised in that said mobile robot is configured to bring said nozzle into the lubricating position after the glass gob has left the parison mould for the blow mould; spray the lubricant into said parison mould; withdraw said nozzle from the lubricating position before the transfer arm returns between the two half-moulds of the parison mould.
