Abstract:
     This invention relates to the production of mineral fibre mats. In considering of this technique, the molten material that is past through the holes drilled on the circumference of the centrifuge and sprayed out from the holes to become single fiber. A stream of air which come from the circumference of centrifuge blow up the single fiber and make it spread. This stream of air presents itself circulating, when it reached to the opening of the centrifuge it becomes nearly cone form. Depending on this invention, the granule of fibre is added by a stream of air which direction is perpendicular to the moving direction of that stream air which blowing up the fresh fibre and blow in from its contracted region.
