Gr?nzweig + Hartmann AG 6700 Ludwigshafen, DE Abstract 1. An apparatus and a process for the continuous production of mineral wool nonwovens. 2.1. The object of the invention is to facilitate an improvement, as compared with the previous apparatus and the previous process for the production of mineral wool nonwovens, in respect of the nonwoven formation process on the drums of the accumulating conveyors arranged at the lower end of a chute. 2.2. The apparatus for continuous production of mineral wool nonwovens features several fiberisation units (1, 2, 3, 4) which communicate with a chute (9) for the formation of a nonwoven (14). The fibres are deposited under the influence of suction pressure onto the curved surface of the accumulating conveyor (10, 11). According to the invention, at least one of the drum-shaped accumulating conveyors (10) is designed to swivel around a pivot (23) essentially arranged perpendicular to the flow direction (22) of the mineral wool such and to the extent that a discharge gap (21) can be adjusted to a width corresponding to the thickness of the nonwoven (14) to be formed. 2.3. Production of multi-layered felt webs. 3. Fig. 2.
