method and device for coating components

摘要

In a process to apply a wood veneer facing material to a wood-based substrate, one bears an adhesive. The veneer is presented to the substrate at an acute angle alpha. A laser beam is directed through the gap between veneer and substrate at the nip gap, activating the adhesive. The veneer (3) and substrate (1) advance together under a rolling press wheel (4). A sensor determines how much energy is taken up by the adhesive and the information is registered by a feedback control system to modify process parameters as necessary e.g. feed rate, laser power, laser beam geometry, press force. The acute angle is less than 20. The laser beam is directed via a lens system or a beam oscillator. The laser beam wavelength is between 800 and 2500 nm or 9 m and 11 m. The laser is a diode laser, a solid body laser, fiber laser or CO(2 laser. Also claimed is a commensurate assembly.
