Lubrication of the parison moulds of a hollow glassware moulding machine is carried out utilizing a spray device in which the discharge of pressurized air from a narrow opening is arranged to entrain surrounding atmospheric air. Liquid lubricant is discharged through a respective opening into this entrained air. Such spray devices have been found to be effective in spraying lubricant down into relatively deep moulds.
