The object of the invention to provide a mineral wool mat with a surface weight as constant as possible. The mineral wool is produced in a line, in which a mineral melt converted into fibres is collected so as to form a thin primary wool mat on a conveyor, which leads to a suspended swing tray conveyor (2) depositing the primary wool mat on a receiving conveyor so as to form a secondary wool mat comprising several layers. The object is achieved by providing the receiving conveyor (1) with means (4) for weighing a surface weight of the secondary wool mat (6) formed on the receiving conveyor (1) and by connecting the weighing means (4) through a regulator to a driving motor (5) of the receiving conveyor (1) for the control of the speed of the motor. |
