摘要： The objective is to provide a process and an apparatus for the continuous production of mineral wool nonwovens, by means of which a stable flow pattern is created in the chute, thus facilitating a clearly defined, homogeneous layer of deposited mineral wool.According to the invention, at least one backflow region (24, 25) is generated in the chute (9) outside the fibre flow (23), which backflow region (24, 25) is sufficient for such a large-volume backflow with such a low mean velocity that appreciable upward fibre transport is avoided. In this connection, a portion (32) of the process air entrained with the fibre flow is deflected upward in the backflow, and another portion (34) of the process air is extracted.

摘要： In the continuous production of mineral wool nonwoven fabrics, fiber/gas/air mixtures (3, 4) produced by several shredding units (14 to 17) are directed onto collecting conveyor units (19, 21) with suction surfaces (c, d) running in a curve and being under suction pressure for the formation of a wool nonwoven fabric (25). In this case the arrangement is such that an imaginary suction surface, increasing in its size in the conveying direction, is assigned to each fiber/gas/air mixture formed by the individual shredding units (14 to 17), actually d is larger than c. As a result it is possible, in a space-saving method of construction and per collecting conveyor unit to produce mineral wool nonwoven fabrics from rock wool with constant suction pressure with bulk densities even under 25 kg/m.sup.3 in good product quality. By series connection of several units or an oscillating deposit of an individual nonwoven fabric multilayer felt webs can further be formed.
