Beschreibung
Zusammenfassung:	A method for constructing panels based on mineral fibres such as glass fibres, rock wool and the like, characterised by spraying onto the mineral fibres under free fall within a collection chamber (1,2) an inorganic size comprising an aqueous solution of a salt which is able to create, by drying, polymeric chains having different molecular weight which have agglomerating functions with respect to the mineral fibres, the felt formed from the thus impregnated mineral fibres then being subjected to heating and compaction at a temperature of 120-180 DEG C to obtain a panel of constant thickness and dimensional stability for subjection to the final cutting and finishing operations.
