Abstract
For producing mineral fiber mats, the flock emanating from the waste to be recycled is stored and classified according to density. Furthermore, the reintroduced quantities are precisely measured and the flock is caused to burst open. Thus it is possible to reintroduce substantially larger quantities without altering either the appearance or the characteristics of the product obtained.
