Abstract

PURPOSE:To accurately reduce the rodlike or tubular glass material in the diameter by grasping both ends of the material with a pair of chuck mechanisms and heat drawing the material at a controlled temp. while turning it on the axial line as a center and moving it along the line. CONSTITUTION:Both ends of a rodlike or tubular glass material 17 are grasped with chuck mechanisms 9, 10. The material 17 turned by the rotation of a motor 4, the outside of one end of the material 17 is heated with burners 20, 20 to soften the end, and by turning carrying shafts 5, 6 with variable motors 7, 8, the mechanisms 9, 10 are moved in the direction of an arrow X. The heated part of the material 17 is also moved, yet since the motors 7, 8 have been made different from each other in rotational frequency so that the mechanism 10 side is moved faster than the mechanism 9 side, the material 18 is drawn and reduced in the diameter in succession. At this time, by setting a temp. regulating mechanism 19A, the temp. is regulated to enable reduction of high accuracy.
