21 A method and an apparatus for the manufacture of mineral wool plates in plants, in which mineral wool is produced suspended in a gaseous medium which is supplied with a binder and whereby the mineral wool is transferred to gas pervious collection conveyors (9, 9') on which the mineral wool deposits in the form of continuous paths whereas the gaseous medium passes through the collection conveyor, and in which the said paths are moved on for being hardened (25), whereby several mineral wool paths (13, 13') are produced, at least one (13') of which is compressed in its longitudinal plane by reducing the moving speed (17, 18) of the conveyor (longitudinal compression), before said several paths are laid together to one single final path (21) which is is subjected to a heat treatment under compression in a hardening oven (22), whereby the binder of the mineral wool becomes hardened, whereas at least another one (13) of said several mineral wool paths is conveyed such that the distance between adjacent points in the longitudinal plane of the path is maintained substantially constant from the moment the mineral wool is deposited on the conveyor until it enters a hardening oven.
