Patent ID: 8869557

Claim:
A method for supplying lubricant to a plurality of lubricating points of an I.S. glassware forming machine, comprising: providing a lubrication system having multiple lubrication circuits, and further having a plurality of lubricant metering devices which output the lubricant to the lubricating points, each of said lubricant metering devices being allocated to one of said multiple lubrication circuits, and wherein the lubricant metering devices of a respective lubrication circuit simultaneously output a predetermined amount of lubricant cyclically whereby successive outputs of said predetermined amounts of lubricant are provided with a time interval between the successive outputs being specific to each respective lubrication circuit; allocating said lubricant metering devices to said lubrication circuits in dependence upon temperatures measured in direct proximity to at least a series of lubricating points, said allocation being carried out such that the temperatures of the lubricating points of a respective lubrication circuit are within a predetermined temperature range; and controlling the amount of lubricant provided at the lubricating points, said controlling step including determining the length of the time interval allocated to a respective lubrication circuit, whilst taking into account a set of evaporation characteristics of the lubricant, in dependence upon temperatures that have been measured in direct proximity to lubricating points of the respective lubrication circuit, by using a set of the evaporation characteristics of the lubricant.
