C03B2205/90 - CPC Classification

Classification description:

Fibre drawing or extruding details; Optical fibre draw furnaces Manipulating the gas flow through the furnace other than by use of upper or lower seals, e.g. by modification of the core tube shape or by using baffles

Sub-classes:

C03B2205/91 » by controlling the furnace gas flow rate into or out of the furnace 13
C03B2205/92 » using means for gradually reducing the cross-section towards the outlet or around the preform draw end, e.g. tapered 4
C03B2205/96 » using tangential feed approximately perpendicular to the draw axis 2
C03B2205/98 » using annular gas inlet distributors 4
