Abstract: An apparatus for coating an optical fibre with a selected one of a plurality of different resins includes respective reservoirs for the resins, an applicator for applying a resin coating to the optical fibre and a distributor between the reservoirs and the applicator including a valve device which is operable for putting any selected one of the reservoirs in flow communication with the applicator. The valve device includes a first body defining a plurality of inlet passages each of which is interconnected to a respective reservoir by a respective inlet conduit and a second body defining an outlet passage which is interconnected to the applicator via an outlet conduit. A flow control device is disposed between the bodies and the bodies are relatively moveable for putting any selected one of the inlet passages in alignment with the outlet passage.
