Abstract:
1. A method of pressing particle mats for making engineered wood panels in a continuous press, the continuous press comprising upper and lower heated plates, upper and lower intake plates projecting on the intake side and designed to form an intake mouth with an intake gap, and respective steel press belts continuously circulating in the upper press part and lower press part, respective arrays of roller rods supporting the press belts on the respective intake plates and heated plates, the height of the intake gap being set, the method comprising the steps of: feeding a particle mat produced in a deposition station upstream of the press and into the continuous press and pressing the particle mat in the press, verifying, setting, or controlling the intake gap height as a function of the weight per unit of surface area of the particle mat such that a particle mat having an actual density or weight per unit of surface area is produced based on a target density or weight per unit of surface area by verifying, setting or controlling the intake gap height as a function of the actual weight per unit of surface area and continuously or quasi continuously measuring the actual weight per unit of surface area upstream of the intake mouth and setting or controlling the intake gap height as a function of the measured weight.
