Abstract
A glass tube extrusion apparatus (50) is comprised of a chamber (52) having a crucible (72) therein mounted within and spaced from an inductive heating coil (77). As a glass tube (170) is extruded from an annular opening (74) in the bottom of the crucible (72) the tube is monitored for bending. When a bend starts to occur an X-Y motion apparatus (54) is activated to move the crucible (72) laterally within the coil (77) in a direction opposite to the bend to straighten the tube (170).
