摘要：A process for the production of insulating material from mineral fibers,preferably rock wool fibers, comprises laying up of fibers treated with binding agents toform a primary felt having a large surface, which is formed into a secondary felt such thathe large surface of the primary felt is converted to form neighboring fiber layers that lienext to each other in the secondary felt. A process for the production of insulatingmaterial (I) form mineral fibers (II), preferably of rock wool fibers, comprises laying up offibers treated with binding agents to form a primary felt having a large surface, which isformed into a secondary such that the large surface of the primary felt is converted toform neighboring fiber layers that lie next to each other in the secondary felt. Themineral fibers in the region of the boundary surface are turned from their originalarrangement in the prima felt by mechanical processing of the secondary felt , over alarge surface, such that individual mineral fibers (II) are arrange neighboring fiber layersin at least some regions. Independent claims are included for: (i) a device for processingan insulating material (I), having a conveying device, that conveys (I) at a set speed, and a
needle block having a multitude of needles, that may be raised and lowered over a largesurface of (I). The needles (6) are inserted in the insulating felt (1) at an angle of 45-135degrees C relative to the boundary surface (4) of neighboring fiber layers (3) tha arealigned to an oscillating primary felt; and (ii) an insulating material (I) having two parallelsurfaces that are opposite to each other, whereby the mineral fibers in individual layersare arranged at an angle of 0-90 degrees to the large surface and the fibers
predominantly run in a main fiber direction parallel to the surface of the fiber layer. Themineral fibers, in the region of the boundary area (4), between neighboring layers (3),have a direction that deviates from the main fiber direction and are preferably at a rightangle to it.
