FIELD: chemistry.
SUBSTANCE: invention relates to methods and apparatus for producing optical fibre. In the method of producing optical fibre, a bare optical fibre is stretched from a workpiece along a first route at a rate of at least 10 m/s; said bare optical fibre is brought into contact with a region of a fluid medium in a fluid bearing and said bare optical fibre is redirected along a second route, when said bare optical fibre is stretched along said region of a cushion of fluid medium. A coating is then applied onto the bare optical fibre and said fibre coating is exposed in at least one exposure zone until partial hardening of said coating, wherein the optical fibre is exposed to UV light.
EFFECT: high rate of stretching fibre without increasing the height of the device used.
