Abstract
In a glassmaking process, a pair of reciprocating blades are used to cut a stream of molten glass into discrete charges known as 'gobs'. The cutting surfaces of the shear blades are maintained in a spaced-apart relationship by pairs of raised portions or rails formed in or on the facing blade surfaces. The raised portions or rails of the blades keep the blades separated a specified distance and thereby extend the wear life of the blades by eliminating friction between the cutting surfaces of the blades. A solid film lubricant is applied to the blades and serves to lubricate both cutting surfaces of the blades, thus the blade surfaces that contact the molten glass stream are lubricated to avoid the possibility of the glass sticking to the shear blades.
