ABSTRACT OF THE DISCLOSURE A nozzle for applying an initial coating of resin to newly drawn optical fibres is made of aluminum, the surface of at least a duct portion of the nozzle being anodized to provide a hard abrasion resistant surface. This avoids the necessity of forming the duct portion itself from hard materials which are difficult to machine.
