Apparatus for and method of processing glass optical fiber, method of manufacturing and method of drawing optical fiber

A method of processing a glass optical fiber drawn from an optical fiber preform when drawing an optical fiber while fusing by heating and pulling by a pulling mechanism one end of the optical fiber preform, the method comprising:

• introducing the glass optical fiber that has passed the pulling mechanism to a shredding unit with an introducing unit that includes:
• a movable unit including a notch configured to fit with a capstan roller included in the pulling mechanism,
• a sliding mechanism that attaches the movable unit slidably with respect to a main body of the introducing unit, and
• a restoring mechanism configured to restore the movable unit to an initial position when the movable unit has slid;
• shredding the glass optical fiber introduced by the introducing unit into glass optical-fiber pieces with the shredding unit;
• suctioning the shredded glass optical-fiber pieces and carrying the glass optical-fiber pieces in a carrier pipe;
• and
• collecting the carried glass optical-fiber pieces.
