Abstract (en)
[origin: EP0162118A1] 1. A method for obtaining a predetermined distribution of weight per unit area in the transverse direction of a pre-mat (4) to be formed on a flat metering conveyor band (5) by means of stripper devices (10), the pre-mat comprising particles (3) containing lignocellulose and/or cellulose, such as chips, fibers or the like, and at least one binding agent dispersed therein for the manufacture of chipboards, fibreboards and like boards, characterized in that measured values representative of the weight per unit area are formed from strip-like regions which adjoin one another in the transverse direction of the pre-mat (4) ; and in that the height of each of these strip-likek mat regions related to the flat metering conveyor band (5) is regulated in dependence on the representively associated measured value by influencing a stripper device (10) associated with the relevant mat region.
