Abstract

The method involves detecting the density of the moving material (3) transverse to its direction of motion and feeding the additive to the material depending on the detected density using control elements driven by density signals for associated areas of material. The density is detected (19a-19e) in individual material areas using light, gas, preferably air, electrical or electromagnetic fields passed through the material. Independent claims are also included for the following: an arrangement for feeding a preferably liquid additive to a moving filter material consisting of expanded fibers.
