Abstract (en)

[origin: WO9950485A1] A method and a device for dissolving isolating material e.g. packaged in bales or similar, so that separate fibres are obtained, providing an isolation, in which the fibres are injected in e.g. building elements, to become as faultless as possible. The package of fibrous material such as the bale is brought to engage a worm device (16) tearing apart the fibrous material into minor parts. These parts are by means of the worm device (16) supplied to a cutter device (40) exposing the fibres contained in the parts. The worm device achieves also a feeding pressure towards the cutter device rendering the exposure of the separate fibres more effective.
