ABSTRACT OF THE DISCLOSURE In the continuous production of mineral wool fleeces, fibre-/ gas-/ air- mixtures (3,4), which are produced by several defibration units (14 to 17), are directed onto collector conveyor units (19, 21) with curved suction surfaces, which are under suction pressure (c, d), for the formation of a wool fleece (25). Here the arrangement is done in such a way, that each fibre-/ gas-/ air- mixture, which is formed by the individual defibration units (14 to 17), is assigned to an imaginary suction surface, which increases in size in the direction of the movement of the conveyor, namely d > c. It is thereby possible, under constant suction pressure to produce mineral wool fleeces of good production quality from rock wools with gross densities of even less than 25 kg/m3 per collector conveyor unit in a space saving construction method. Furthermore, composite webs of felt can be formed by several units connected in series or by way of a pendular deposit of a single fleece.
