Abstract
A molten glass cutting apparatus comprises a pair of shear blades and a control unit that controls a pair of the shear blades to relatively move toward each other. The control unit controls a pair of the shear blades to relatively move so that tip parts of a pair of the shear blades overlap, and shearing force by cutting edges of a pair of the shear blade cuts molten glass extruded from an orifice formed at a bottom part of a spout. When a central part of molten glass is offset with respect to a central axis of the orifice, the control unit offsets a position of cutting by a pair of the cutting edges to a side of the central part with respect to the central axis.

A molten. glass cutting apparatus, comprising:
- a pair of shear blades arranged below a spout storing molten glass and above a funnel;
- and
- a control unit that controls a pair of the shear blades to relatively move toward each other,
- wherein:
- the control unit controls a pair of the shear blades to relatively move so that tip parts of a pair of the shear blades overlap, and shearing force by cutting edges of a pair of the shear blade cuts molten glass extruded from an orifice formed at a bottom part of the spout;
- and
- when a central part of molten glass at a predetermined position between being extruded from the orifice and reaching the funnel is offset with respect to a central axis of the orifice, the control unit offsets a position of cutting by a pair of the cutting edges to a side of the central part with respect to the central axis.
