Abstract (en)
[origin: WO9416164A1] A method of producing a mineral fiber-insulating web comprises the steps of firstly producing a first non-woven mineral fiber web defining a longitudinal direction parallel with the mineral fiber web transversal direction parallel with the mineral fiber web. Secondly, the web is moved in the longitudinal direction and cut parallel with the longitudinal direction and perpendicular to the transversal direction so as to produce a plurality of parallel strips. Thirdly, the strips are tilted so as to turn the mineral fibers of each of the strips from the arrangement in the transversal direction to an arrangement perpendicular to the longitudinal direction and the transversal direction. The tilted strips are thereupon adjoined so as to produce a second non-woven web containing mineral fibers arranged perpendicular to the longitudinal and transversal directions. A third non-woven mineral fiber web is produced and adjoined to the second mineral fiber web.
