Abstract
The production of a mat of wood chips and/or fibers, hereafter called wood particles, by a spreading station and a weighing device, is controlled in a closed loop circuit for uniformity, directly during the spreading of the wood particles. Several spreading devices form a spreading station. Electrical signals emanating from a tared weighing device which is arranged downstream of a first spreading device as viewed in the direction of travel of a conveyor belt, are used to control the output of the first spreading device. If desired, the output of one or more spreading devices located downstream of a weighing device may also be controlled in a closed loop circuit, whereby the weight of the partially formed mat moving over the weighing device produces the electrical control signal which is compared to a predetermined reference signal for controlling the production of the finished mat having one or several layers.
