Method for regulating a weight related parameter in a mineral fibre felt, in mineral fibre production. The speed of the fibre felt is regulated by a feed-forward connected regulator (R1) based on the power consumption of the fiberizing unit (2). The regulator (R1) is corrected with a feed-back connected regulator (R2) wherein the measured signal is a weight related parameter measured at a location in the beginning of the felt forming line. The regulator (R2) in turn is corrected by a third feed-back connected regulator (R3) wherein the measured signal is a weight related parameter measured at a point at the end of the felt forming line. |
