Abstract
When manufacturing mineral fiber products with compressed surface areas made of mineral fiber webs, in which the fibers extend substantially parallel, perpendicular or obliquely to the large surfaces of the mineral fiber web, which contains an uncured binder, it is very important to achieve a high tearing resistance and a strong fiber connection between the compressed surface areas or layers and the remaining part of the mineral fiber web. It is therefore proposed to expose at least one surface area to needling down to a predetermined penetration depth, in order to felt the fibers and at the same time to compress the surface area.
