Abstract (en)
The invention relates to the techniques of producing mineral-fibre mats. <??>It is proposed to store the flakes originating from the waste to be recycled. For storage, the flakes are graded according to their density. On the other hand, the quantities reintroduced are accurately metered, and the flakes are broken open. <??>Substantially larger quantities can thereby be reintroduced, without modifying either the appearance or the characteristics of the product obtained. <IMAGE>
