When forming fibres of heat-softenable vitreous material by projecting streams of the material by centrifugal force outwardly from a rotating annular body of the material, heat is supplied to the environment of the body and the streams so that the streams continue to lose heat, but at a slower rate than in the absence of the heat supply, the heat being supplied and controlled independently of the traction forces.
