ABSTRACT:
Glass gob shearing apparatus having opposed shear blades that reciprocate along generally parallel, opposed horizontal paths to periodically bring the shearing ends of the shear blades into partly overlapping contact with one another, to thereby shear a gob of molten glass from a stream of molten glass flowing downwardly between the shear blades. Contact loads between the shear blades are reduced by placing a shim between one of the shear blades, namely the shear blade that is the lower of the shear blades when they are in contact with each other, to thereby impart a slight downward inclination to such shear blade with respect to the other shear blade. Contact loads between the shear blades are further reduced by resiliently mounting the other shear blade to the blade holder to which it is attached, and this is done by positioning curved spring washers between the other shear blade and the blade holder to which it is attached.
