Abstract
Method and apparatus for removing fibres and other particles from the surfaces of compressible mineral wool products, for instance, mineral wool plates (2), by means of one or more suction slot nozzles (5) which suck air from adjacent the surfaces of the mineral wool products. The mineral wool products, while being exposed to the suction of slot or slots (5), are subjected to a quick compression so that a part of the air enclosed in the mineral wool is forced out towards the suction slot or slots (5) thereby bringing loose fibres and other particles at and adjacent the surfaces into the suction slot or slots (5).
