Gr?nzweig + Hartmann AG 6700 Ludwigshafen, DE Abstract 1. A process and an apparatus for the continuous production of mineral wool nonwovens. 2.1. 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. 2.2. 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. 2.3. Production of mineral wool. 3. Fig. 1
