A method and an apparatus in the in the manufacture of mineral wool products from a path of mineral wool (1) by split cutting the mineral wool path (1) into two or several layers (6, 7) by split cuts which are parallel to the plane of the mineral wool path (1), which method and apparatus are useful in reducing the spreading of dust from the mineral wool products thereby provided, by vacuum exhausting loose fibres and other particles by means of vacuum means (9) introduced in between the layers (6, 7) formed by the split cutting, whereby the split surfaces (27, 28) just formed are vacuum cleaned, whereupon the layers (6, 7) are moved together again. |
