  • Apparatus and method for drawing an optical fiber from a solid blank
    Patent number: 5160359
    Abstract: For the drawing of an optical fiber from a solid blank, the latter is conducted vertically through a furnace and, during this process, is heated to the drawing temperature at its lower end, from which the fiber is drawn out in the form of a drawing onion. The drawn fiber is then cooled down from the drawing temperature by means of a gas stream moving in the opposite direction to the drawing direction and, in this process, a rotational flow is impressed on the cooling gas stream in addition to the longitudinal flow.
