The present invention relates to a device for the internal centrifugation of fine mineral fibres, a method for forming fine mineral fibres, and paper containing fine mineral fibres.

Device and method for the centrifuging of mineral fibers

A process and apparatus for controlling the manufacture of mineral fibers, in particular glass fibers, by use of a fiber-drawing process using internal centrifuging in a centrifuger. The peripheral strip is pierced by a large number of outlet orifices and the radiation emitted superficially by the peripheral strip is measured in order to determine the temperature of points of the peripheral strip and the vertical coordinate of each of the points measured.

Process for controlling the temperature of a fiber centrifuger

A fibrous mineral material serving as an absorbent, especially for hygienic products such as diapers, sanitary napkins, bandages and similar products, is comprised at least partially of these mineral fibers, which have a specific surface area greater than 0.25 m.sup.2 /g. The material has an appreciably greater absorption capacity than the regularly-used cellulose fluff-based products.
