<p>The invention relates to a method and an arrangement for cross-cutting a moving mineral wool web. The mineral wool web is cut in the cross direction of the web with the aid of a cutting device arranged on a first bridge extending across the moving web. During cutting the first bridge with its cutting device is moved in the motion direction of the web and with a speed, which is adapted to the speed of the web, so that a substantially perpendicular cutting line is obtained in the cross direction of the web. In addition the mineral wool web is cut in the cross direction of the web with at least a cutting device arranged on a second bridge extending across the web, adjacent the first bridge. The distance between the bridges is kept substantially constant during the cutting. <IMAGE></p> |
