ABSTRACT OF THE DISCLOSURE A method and an apparatus in a plant for fibrating mineral molten material which in the form of a stream of molten material is discharged to the peripheral surface of a primary spinner wheel and which is formed to mineral fibres by being thrown out from the spinner wheel or from several cooperating spinner wheels. The distribution of the stream of molten mat- erial over the width or length of the primary spinner wheel is improved in that the force is applied to the incoming stream of molten material, especially from the rear side thereof as seen in the rotation direction of the spinner wheel, which force is act- ing in a plane substantially perpendicular to a generatrics to the peripheral surface of the spinner wheel and in a blunt angle to the stream of molten material. The force acts on a stream of molten material a short distance in advance of the place where the material comes into contact with the spinner wheel, and the force provides a widening of the stream of molten material without breaking same up into small fragments. The force may be provided by a gas flow or by different mechanical deflector means.
