The invention relates to a method for producing particularly large-sized roof insulation plates made from fibre materials, whereby mineral fibres are produced from a silicate melt and deposited with a binding and/or impregnating agent as a mineral fibre strip on a continuous conveyor. Said mineral fibre strip is mechanically machined and fed into a hardening furnace and finally divided into plates along the cutting surfaces. The invention also relates to a device for producing roof insulation plates and implementing said method, with a conveying route along which the roof insulation plates are conveyed to the packing station. In order to create a method and a device for implementing said method which enable the simple and cost-effective production of roof insulation plates with greater dimensional accuracy, the plates are accurately arranged on the continuous conveyor both lengthways and widthways, the two dimensions forming a right angle. The narrow edge of the roof insulation plates is finally trimmed so that said plates have a maximum deviation widthways measuring +/- 0.5 to 1 mm and/or a maximum oblique angle of the cutting surfaces relative to the longitudinal surfaces of 0,5 to 1 mm, in relation to a length of 1 m. A stop, which can be brought into the conveying route, is arranged in the conveying route at a right angle relative to the direction of conveyance. A device for cutting or machining the side-surfaces of the roof insulation plates which extend substantially parallel to the direction of conveyance is placed after the stop.
