Coating device comprising flowing coating material for smooth or structured surfaces
View Patent ↗The invention relates to a device for coating plates ( 6 ) in circulation. Said device comprises a transport system for transporting plates ( 6 ) and a feeding device ( 5 ) which can apply the coating material ( 8 ) to the surface of the plates. Means ( 7 ) for drying and/or hardening the coating material are provided next to the feeding device and above the plates. Contrary to state of the art devices, said inventive device comprises means which enable a material web ( 3 ) to pass between the transport elements for the transport of plates and means ( 7 ) for drying and/or hardening.
1. Apparatus having transport means for transporting boards,
a supply arrangement for supplying coating material onto the surface of the board,
means for drying and/or curing the coating material supplied to the surface of the board,
means with which a web can be passed between the transport means for transporting boards and the means for the drying and or curing, and
a collecting arrangement for coating material and rollers for transporting the web arranged thereon, such that the web and the collecting arrangement form the supply arrangement for supplying the coating material between the surface of the board and the web, which has a funnel-shape in cross-section.
2. Apparatus according to claim 1 , in which the supply arrangement comprises the collecting arrangement for the coating material, by means of which the coating material may be passed between the surface of the board and the web.
3. Apparatus according to claim 1 , wherein the web has a structured surface.
4. Apparatus according to claim 1 , having one or more additional rollers for the de-reeling of the web as well as one or more additional rollers for the rolling-up of the web.
5. Apparatus according to claim 1 , wherein one or more of the rollers may be raised and/or lowered, to adjust the thickness of the coating.
6. Use of an apparatus according to claim 1 , for the coating of a surface, wherein sufficient coating material is supplied between the web and the surface of the board, such that no air is enclosed and such that the coating may subsequently be cured by means of UV light or electron beams.
7. Use according to claim 1 , wherein the coating material comprises a paint which is curable by means of UV light or electron beams.
