The invention relates to the blowing of fibrous materials of the glass wool type, which material has the form of nodules of small dimensions. According to the invention, the material is blown by means of a centrifugal fan, the speed of the air entraining the material being, at the inlet of the fan, greater than 15 m/s. In addition to convenience of implementation, this technique makes it possible to give the material very good insulating qualities. <IMAGE>
