Abstract
Abstract A device for an intermittent application of a lubrication or a separation liquid to a component part of a glass-forming machine engageable with molten glass, includes an intermittently driven high-pressure pump and a spraying nozzle connected to the pump by a pressure conduit to apply momentarily a cone of atomized lubrication or separation liquid on the machine part at a pressure of at least 100 bars.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
100 words
A method of an intermittent application of a lubrication or separation liquid without admixture of a carrier gas on at least one part of a glass-forming machine prior to its contact with the processed molten glass, such as shearing blades for shearing gobs off a glass strand, a gravity tube or a chute for guiding glass gobs, a mold, a mold part or a press plunger, comprising the steps of momentarily compressing the lubrication or separation liquid to a pressure exceeding 100 bar; then atomizing the compressed liquid; and applying a cone of the atomized liquid onto said machine part.
Claim 2
Independent Claim
