Embodiment Construction

[0035] Referring first to Figure 1, a production line for producing layered substrates in which the system and method according to the present invention may be used will be described.

[0036] The production line 10 comprises: means for applying a hardener 16 adapted to apply the hardener to the substrate 12, such as a coater; means for applying the resin 18 to the substrate, such as a resin coater; and extrusion means 20, For example a hot rolling mill adapted to apply at least one layer to the substrate to form a layered substrate. However, a person skilled in the art will recognize that the layer can be applied to the substrate by means of, for example, planking, veneering or foiling. For example, the layer may be paper, veneer or fabric. In addition, it should be noted that there are many other suitable extrusion devices besides hot rolling mills, which may include plane pressing machines or cold presses, however plane pressing machines are not suitable in the case of foi...

Abstract

The present invention relates to a method, a system, computer readable mediums and computer program products for controlling a process for producing a layered substrate. The method comprises the steps of: collecting (32) at least one first set of measurement data related to parameters of a substrate at a first process stage located upstream a pressing step in the translation direction (A) of the conveying means (14); collecting (34) at least one second set of measurement data related to parameters of the substrate at a second process stage located upstream a pressing step in the translation direction (A) of the conveying means (14); and controlling (36) resin dosage by using collected measurement data from the first and second process stage and a calculated calibration model, which model is based on collected measurement data of substrates at the first and / or second process stage.

Description

technical field [0001] The present invention relates to the production of layered substrates, and more particularly to a method and system for monitoring or controlling the application of resin in the production of layered substrates, including layered wood-based products. Background technique [0002] Layered substrates, such as layered wood-based products, are generally manufactured by applying layers to a substrate, such as a board. For example, suitable boards include: particle board, medium density fibreboard, laminated board, dry glue board, oriented strand board (OSB), hardboard. For example, for the production of paper laminated particleboard, laminate flooring, parquet, medium density composite (MDO) laminates, formwork, plywood, etc., the layers are applied by veneering, planking or foiling onto the board. When applying the layers, many different resin applicators can be used, including glue rolls, curtain coaters, extruders, sprayers, and more. [0003] However...
