A shear mechanism is disclosed including reciprocating pairs of upper and lower shears. A gob guide is associated with each upper shear blade and can be selectively adjusted in the direction of shear movement and in a direction transverse to that movement.
Claims4
A shear mechanism for shearing discrete gobs from a runner of molten glass comprising
- a shear assembly,
- a frame including opposed ends,
- a pair of parallel guide rails extending horizontally between said ends,
- means for mounting said shear assembly on said guide rails for reciprocating longitudinal displacement,
- said shear assembly including at least one shear,
- a corresponding number of gob drop guide assemblies, each including a base portion and a top portion having a drop guide,
- said base portion including means for supporting said top portion for horizontal linear displacement transverse to the longitudinal direction of displacement of said shear assembly,
- means for selectively longitudinally displacing said base portion relative to said associated shear and
- means for transversely displacing said top portion relative to said base portion at any longitudinal position of said base portion.
