Abstract
Method and apparatus for the manufacture of one-dimensional or multi-dimensional curved or angularly formed, preferably moldings of mineral wool, which is impregnated with a binder, in that a matching or chosen piece of binder impregnated mineral wool felt (9) or mineral wool is compressed between mold parts comprising a matrix (4) and a counter die (1), whereafter the matrix (4) and/or the counter die (1) cures the binder of the mineral wool body formed by the matrix and the counter die, whereby the mineral wool felt (9) is compressed in two or several steps, namely in at least a first step between the counter die (1) and a portion (5) of the matrix (4), whereafter the remaining part (6) of the matrix (4) in one or several successive steps is fold or pressed to the mineral wool felt (9), so that all remaining parts thereof are pressed to the counter die (1), whereby all parts of the mineral wool felt (9) is given a predetermined thickness.
