| description | The invention relates to a method in the manufacture of mineral fibres, in which mineral melt is led to a first rotating fiberising rotor in a fiberising arrangement comprising at least two fiberising rotors and thrown from the mantle surface of the first rotating rotor to the mantle surface of the second rotating rotor, and from that location on successively forward to the mantle surfaces of all possible following rotors. Mineral melt is then formed to mineral fibres at the active peripheries of rotating rotors, and the formed mineral fibres are blown off from the fiberising rotors of the fiberising apparatus with the aid of fibre blow- off means arranged at the active peripheries towards a collecting member. Binder is applied to the mineral fibres during their formation by means of a binder applying member arranged at the active peripheries of the rotors. The active periphery of the at least one of the fiberising rotors is divided into at least a first section and a second section, and a binder applying member and/or fibre blow- off means at the first section are controlled independently of the binder applying member and/or fibre blow-off means at the second section. The invention also relates to an apparatus for the manufacture of mineral fibres as well as arrangement with a fiberising rotor. |
