Abstract
Method for the production of binder-bound mineral wool products, in which mineral fibers are deposited on a production surface (13) to form a mineral wool web (12) and are compacted, and their relative positions are reoriented by mechanical action, for which purpose the web is guided on its large faces and at the same time forces, in particular upsetting forces, are introduced into the web in parallel with the large faces, the forces being introduced in introduction regions which are located next to one another transversely to the running direction in zones and in each case at a distance from one another and one behind the other in the running direction in longitudinal zones, and the introduction regions of adjacent longitudinal zones being arranged so as to be offset relative to one another, after which the binder is cured. The introduction regions are designed to be elongated in the running direction (14) of the mineral wool web (12), and the introduction regions of longitudinal zones located next to one another form overlap regions (27; 127). As a result, such high longitudinal forces can be introduced into the web that the material of the mineral wool web is exposed to a fullin…
