Abstract

In the continuous production of non-woven mineral wool, fibre/gas/air mixtures (3, 4) generated by a plurality of unravelling units (14 to 17) are directed, to form a wool lap (25), onto collecting conveyor units (19, 21) having curved suction surfaces (c, d) which are under suction pressure. The arrangement is such that each fibre/gas/air mixture formed by the individual unravelling units (14 to 17) is assigned an imaginary suction surface increasing in size in the conveying direction, specifically d c. It is thereby possible, in a space-saving design, with a constant suction pressure to produce on each collecting conveyor unit mineral-wool laps of rock wool with bulk densities even below 25 kg/m<3> of good product quality. Furthermore, multi-layered felt webs can be formed by connecting a plurality of units in series or by an oscillating deposition of an individual lap. <IMAGE>
