Abstract
Angular blocks of foam flocks can be produced by the composite process with angular edges and a homogeneous density distribution over the entire cross-section in a molding box by first extending the filling cross-section in the comers of adjoining mold walls before the flocks are introduced, and, after the flocks have been introduced, reducing it to the envisaged cross-section of the slab to be produced and thus filling hollow spaces, and compacting the flock filling to the desired density in the comers, so that the slab has a homogeneous density over the entire cross-section.
