Abstract
The inventions relates to a method for producing a decorative workpiece with a structured surface comprising the following steps: (B) applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm; (E) applying a second liquid, at least partially transparent lacquer for producing a fine structuring in some regions. Furthermore, an apparatus for performing the method and a workpiece produced by the method are claimed.

An apparatus for performing a method for producing a decorative workpiece with a structured surface comprising the following steps:
- applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm;
- and
- applying a second liquid, at least partially transparent, lacquer for producing a fine structuring in some regions,
- the apparatus comprising:
- a coating station for applying the first liquid lacquer with the coarse structuring to the workpiece over the entire surface, in which a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm;
- and
- a station for applying the second liquid, at least partially transparent, lacquer for producing the fine structuring in some regions wherein
- the coating station comprises at least one printing roller, and
- the at least one printing roller is configured to unroll the first lacquer on a surface of the workpiece, and/or in that
- the apparatus comprises a device for feeding the workpiece to the coating station, and
- the device for feeding the workpiece to the coating station is configured to feed the workpiece to the coating station, and/or in that
- the apparatus comprises a station for at least partially curing the first lacquer, and the station for at least partially curing the first lacquer is configured to at least partial cure the applied first lacquer, and/or in that
- the apparatus comprises a station for curing the second lacquer, and
- the station for curing the second lacquer is configured to cure the second lacquer, wherein
- the difference in thickness in the region of fine structuring on the second lacquer layer is less than 50 μm, in particular less than 30 μm.
An apparatus for performing a method for producing a decorative workpiece with a structured surface comprising the following steps:
- applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm;
- and
- applying a second liquid, at least partially transparent, lacquer for producing a fine structuring in some regions,
- the apparatus comprising:
- a coating station for applying the first liquid lacquer with the coarse structuring to the workpiece over the entire surface, in which a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm;
- and
- a station for applying the second liquid, at least partially transparent, lacquer for producing the fine structuring in some regions wherein
- the station for applying the second lacquer is configured to first apply a liquid lacquer to produce the second lacquer layer and then to spray lacquer droplets of the second lacquer layer into the still liquid material to produce a fine structuring.
An apparatus for performing a method for producing a decorative workpiece with a structured surface comprising the following steps:
- applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm;
- and
- applying a second liquid, at least partially transparent, lacquer for producing a fine structuring in some regions,
- the apparatus comprising:
- a coating station for applying the first liquid lacquer with the coarse structuring to the workpiece over the entire surface, in which a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm;
- and
- a station for applying the second liquid, at least partially transparent, lacquer for producing the fine structuring in some regions, the apparatus further comprising:
- an application device configured to apply a decorative image to the workpiece and/or one of the applied lacquer layers, wherein
- the application device comprises in particular a multicolour digital printer, and/or
- a coating station and/or a device for feeding the workpiece to the coating station, and/or
- a station for at least partial curing of the first lacquer, and/or
- a station for curing the second lacquer, wherein the difference in thickness in the region of the fine structuring of the second lacquer layer is less than 50 μm, in particular less than 30 μm.
