1. Process for the manufacture of webs of mineral fibres, in which - fibres are produced and then carried by gas currents to a receiving device (3) where they are collected and separated from the carrier gas, - a finely dispersed liquid binder composition is projected into the gas current carrying the fibres, upstream of the receiving device (3), - the web of fibres (6) is optionally treated, in particular heat treated, to fix the binder, and subjected to transformations leading to its final form, - water is sprayed into the path of the gas which has carried the fibres, downstream of the receiving device, and/or that of the gas emanating from the treatment operations for fixing the binder and/or the transformation of the mat of fibres (6), characterised in that the water is dispersed by the collision of jets directed towards one another so that a sheet of dispersed water forms transversely to the path of the gas. |
