Abstract: A spinner for fiberizing mineral fibers, in particular glass fibers, by centrifugation from a molten material, includes a peripheral barrel pierced with orifices for the passage of the molten material and for obtaining fibers by drawing during the centrifugation, a wheel center connecting the peripheral barrel to an upper flange for securing the spinner in a fiberizing device, a turnup extending the peripheral barrel in the bottom part of the spinner and making an angle β herewith, wherein the angle β is strictly less than 90°.
