Abstract

Prior art devices for producing mineral fibres from a melt exist which have one or more rotating bodies which turn about a horizontal axis and on to whose outer surfaces the melt is fed and drawn out by the centrifugal force to form fibres. In order to provide a device which enables the scatter in fibre diameters to be kept within as narrow a range as possible about the required mean diameter, while at the same time significantly decreasing the proportion of material lost as waste during the formation of fibers, the invention proposes that the rotating body has three zones lying adjacent to each other along the axis of the rotating body: a melt-feed zone, a distribution zone and a fibre-formation zone with peripheral apertures, and that the diameter of the rotating body increases from the melt-feed zone through the distribution zone to the fibre-formation zone.
