ABSTRACT:
A method and an apparatus for manufacture of moulded mineral wool objects which are bound by a binder and which have a substantially constant cross-section along their entire lengths, whereby mineral wool in the form of flocks and/or granules which are impregnated or mixed with a binder and which are collected in a feeding chamber to which a mould channel is connected. The mineral wool is continuously or stepwise pressed by a compressing device into and through the mould channel and during the movement therein it is subjected to a heat treatment to cure the binder of the mineral wool, whereupon the continuous body of bound mineral wool is expelled from the channel. If desired it is subjected to a surface treatment or any subsequent treatment and is cut into intended lengths. The channel may include one or more cores providing one or more axial bores through the mineral wool body. A suction fan may be provided adjacent the inlet end of the channel, the suction side of which is connected to the interior of the channel to suck flocks and/or granules of mineral wool into the channel, whereas the pressure side thereof is connected to the feeding chamber to keep the flocks and/or granules of mineral wool fluidized.
