The method provides a higher gluing capacity upon reduced gluing agent consumption. The short-fibre component is glued in advance with a rosin glue and aluminium sulphate. Afterwards, the obtained aluminium resinate Al./C19H29COO/3 is fixated on the short fibres to a pH value of 4.3-4.5 and then is mixed with the long-fibre component.<IMAGE>
