    • An apparatus (20) for the continuous production of a mattress (14) of agglomerated mineral fibres is described, comprising a mineral fibre receiving or forming chamber (2), an accumulator conveyer (3) arranged below the receiving or forming chamber (2) and comprising adjacent drums (4) provided with perforated or gas-permeable circumferential surfaces (5) for receiving and accumulating the fibres to form a mattress (14) comprising mineral fibres between the drums (4), a gas extraction device (6) in fluid communication with the perforated or gas-permeable circumferential surfaces (5) of the drums (4) and a lower space between the drums (4) for unloading the mattress (14) of mineral fibres formed between the drums (4), the apparatus (20) being characterized in that said drums (4) comprise each a first half-drum (4a) and a second half- drum (4b) telescopically connected with each other and which are movable along the axis of rotation (X) between a first stroke-end position in which the first half-drum (4a) and the second half-drum (4b) are juxtaposed or in contact with each other, and a second stroke-end position in which the first half-drum (4a) and the second half-drum (4b) are spaced apart from each other at a predetermined maximum distance along the direction of the axis (X) of rotation of the drums (4), a gas-permeable or perforated circumferential band (22) being furthermore provided, which overlaps at least one of said first half-drum (4a) and said second half-drum (4b) at opposite end portions of said half-drums (4a,4b).

    • The invention relates to an apparatus for manufacturing mineral wool. The apparatus includes means (1) for producing molten mineral material, at least one fiberizing device (3) for forming fibres, into which fiberizing device the molten mineral material is fed (2) and by which fibres (12) are formed. The fiberizing device (3) comprises, rotationally arranged around a vertical axis (15), at least one fiberizing plate (13) having a vertical peripheral edge, into which are formed numerous small-sized holes (14), through which the molten material is led by centrifugal force to form fibres (12). Into the fiberizing device (3) are arranged elements to produce a vertical flow of blowing medium (16) to be led around the fiberizing plate (13), the flow causing the fibres (12) to turn downwards and, at the same time, to thin. Downstream the fiberizing device (3) is arranged a collection device (6), into which the formed fibres (12) are led and collected into a mat-like material. In connection with said at least one fiberizing plate (13) is arranged a substantially horizontal, relatively narrow channel (5), through which the fibres (12) are brought into the chamber space (7) of the collection device (6). The invention further relates to a method for manufacturing mineral wool and a mineral wool product manufactured by the method

    • Collecting chamber comprising at least one adjustable wall and process for collecting of mineral wool solves technical problem of reducing shot in fiber production and/or reducing clumping of fiber by manipulating cross section and shape of entry zone (comprised of shot separation section (I) and/or adjustable section (II)). Such manipulation may serve two purposes: to reduce vortices and/or recirculation cells within collecting chamber, and to separate shot from fiber. There are many ways to achieve such manipulation. There can be apertures, moving walls, objects, membranes and other means for achieving said goal. Above referenced technical problem is also solved by a process comprised of following steps: - pouring mineral melt onto at least one spinner to discharge said mineral melt in form of droplets - blowing said droplets to elongate into fiber separating said fiber from shot formed by premature freezing of said drops by means of an adjustable wall (15, 12) in accordance with description above.
