Abstract (en)
[origin: WO2009068738A1] The invention relates to a method and device for making a roll (12) from a mineral wool band or mat (11), wherein the mineral wool band or mat is rolled in a rolling space (R) defined by three rolling elements (1, 2, 3) between themselves. In the method and device, the cross-section of said rolling space (R) in a direction perpendicular to the rolling axis of a rolling motion is substantially in the shape of a triangle, and the density of the mineral wool roll (12) is adjusted according to a change in the size of the rolling space (R) brought about by a change in the size of the roll in such a way that the density of mineral wool remains substantially constant across the entire roll (12).
