Estimating the term…
A process for manufacturing products of mineral wool, in particular monolayer and multilayer products of rock wool, wherein the mineral wool material of a primary mat (2, 2′) is mechanically comminuted by a combined beating and cutting process into mineral wool flakes (9) of a predetermined size and subsequently recombined for forming a final mat (4). By means of such a treatment of the mineral wool material, practically any inhomogeneities and imperfections in the primary mat (2, 2′) are eliminated, i.e., they are not present any more in the final mat (4). The process of the invention thus results in the final mat (4) 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.
Process for manufacturing products of mineral wool, wherein initially at least one primary mat having a preferably laminar fiber structure is produced, which is then further processed into a final mat, characterized in that the mineral wool material of the primary mat (2, 2′) is mechanically comminuted or decomposed in such a way from its state integrated into the mat into mineral wool flakes (9), and subsequently the mineral wool flakes (9) are again collected for forming the final mat (4) in such a way that the mineral wool material exhibits isotropic properties after its renewed collection in the final mat (4).
