  • Patent number: 5609816
    Abstract: In a process for preparing a molding from fibers and/or flakes and thermoplastic binder, the material is introduced into a mold, compacted, and bonded by thermal effect. To make it possible to introduce the material rapidly and such that a consistently equal density or a density changing in a defined pattern will be obtained, a filling contour calculated for the given molding is formed by a first mold disk set. After filling the filling contour, a first finished contour mold is positioned against it. A second mold disk set, whose disks are displaceable between the disks of the first mold disk set and form the second finished contour of the molding, is subsequently displaced in the first mold disk set against the first finished contour mold, while the material present in the filling contour is compacted. The material is subsequently fixed by thermal effect.
