Patent number: 6858261Abstract: The invention relates to a method of drying coated and/or impregnated objects (5), in particular lacquered wood, wherein [drying of] a coating agent and/or impregnation agent applied to the surface of the object concerned is completed before a characteristic period of time has elapsed, by irradiating the coated or impregnated surface with infrared radiation. The characteristic period of time is determined by the time needed for components of the coating and/or impregnation agent (22) to migrate away, i.e. by penetrating into the object (5), so that the quality of the coating or impregnation is impaired. Alternatively or in addition, the characteristic period of time is determined by the fact that after it has elapsed, a solvent and/or dilution fluid that is contained in the coating and/or impregnation agent (22) and is to be driven out and/or bound during the heating process has caused fibers in the object (5) to be raised up, so that a secondary treatment of the surface is necessary or desirable.Type: GrantFiled: October 21, 1999Date of Patent: February 22, 2005Assignees: Advanced Photonics Technologies AG, Josef Schiele oHGInventors: Kai K.
