ABSTRACT:
A process for manufacturing mineral wool products according to which the mineral wool is collected to form a mattress on a conveyor belt, carried to a conforming and binder polymerizing chamber consisting of two complementary calibrating and transport conveyors consisting of a plurality of articulated perforated elements of pallet type. The speeds of the two conveyors are different, the difference in speed corresponding along the entire length of the chamber to a staggering of a length equivalent to at least the width of one pallet so that one of the faces of the mattress is smoothed during conformation of the mineral wool product.
