Abstract
Products of mineral wool, in particular monolayer and multilayer products of rock wool, are manufactured wherein the mineral wool material of a primary mat is mechanically comminuted by a combined beating and cutting process into mineral wool flakes of a predetermined size and subsequently recombined for forming a final mat. By such a treatment of the mineral wool material, practically any inhomogeneities and imperfections in the primary mat are eliminated, i.e., they are not present any more in the final mat. The process of the invention thus results in the final mat in products having a three-dimensional, isotropic fiber structure, which brings about a noticeable economy in the bulk density, at an at least equivalent quality in comparison with conventional crimped products.
