Definitions

• the present invention is based on the insight that the effect of penetration of resin into the substrate is essential when determining the resin application (the resin dosage) due to the fact that the amount of resin penetrating into the substrate is not taking part in the glue joint in the gluing process of the product (depending on the penetration depth).
• the penetration of resin into a substrate such as a particleboard, might be related to parameters such as moisture content, hydrophobic properties of the substrate surface, etc.
• the invention is also based on the insight that these properties can be quantified by spectroscopy using measurement probes located at, at least two specific process stages along a production line for producing layered substrates.
• Fig. 3 is a schematic view of a system for monitoring resin-application during production of a layered substrate at the production line shown in Fig. 1 according to another embodiment of the present invention.
• the control means 28 is also adapted to control the resin spreader 18 in order to determine an amount of resin to be applied on a substrate during the process for producing a layered substrate.
• This control of the resin spreader 18 is performed by using collected measurement data, which may be stored in the storage means 29, from the first and/or second measurement means 24 and 26, respectively, and a calculated calibration model, which may be stored in the storage means 29.
• the calibration model is based on collected measurement data of substrates at the first and/or the second process stage.
