Method for manufacturing a floor board
A method of manufacturing a floor board comprises the steps of supplying a panel, printing a curable substance or surface removing substance onto the panel in a predefined pattern for creating an elevation on the panel at the pattern or removing a portion of the surface of the panel at the pattern, respectively, and curing the curable substance or removing any reaction products of the surface removing substance and the panel.
1. A method of manufacturing a floor board, comprising the steps of:
supplying a panel,
printing a substance onto the panel in a predefined pattern for creating an elevation on the panel at the predefined pattern, wherein said substance comprises a liquid and a powder, the substance is printed onto the panel by printing the liquid onto an initial upper surface of the panel in said predefined pattern, and then providing the powder to the liquid,
heating the powder so that the powder is melted together into a single mass which is elevated above the initial upper surface of the panel, hence forming the floor board;
wherein the liquid evaporates during the step of heating the powder.
2. A method according to claim 1 , wherein the step of printing is digitally controlled.
3. The method according to claim 1 , wherein a maximal thickness of the substance lies between 20 and 250 μm above the initial upper surface of the panel.
4. The method according to claim 1 , wherein the maximal thickness of the substance lies between 5 and 1000 μm above the initial upper surface of the panel.
5. The method according to claim 1 , wherein a first portion of the powder sticks to the liquid whereas a second portion of the powder not sticking to the liquid is removed.
6. The method according to claim 5 , wherein the abundant powder is removed by suction.
7. The method according to claim 1 , wherein the panel comprises a decorative pattern prior to the printing of the substance to the panel.
8. The method according to claim 7 , wherein the decorative pattern is directly printed on the panel.
9. The method according to claim 1 , wherein the panel comprises an embossment prior to the printing of the substance to the panel.
10. The method according to claim 1 , wherein the panel comprises a flat surface.
11. The method according to claim 1 , wherein the liquid is transparent or colored.
12. The method according to claim 1 , wherein in said heating step an entirety of the panel including the substance is placed in a heated environment.
13. The method according to claim 12 , wherein after heating said panels are cooled before storing.
14. The method according to claim 1 , wherein the powder comprises wear resistant particles.
15. The method according to claim 1 , wherein the predefined pattern substantially corresponds to a decorative pattern present on the panel prior to printing of the substance.
16. The method according to claim 1 , wherein the substance is printed beside a predetermined portion of the predefined pattern to form a depressed portion.
17. A method of manufacturing a floor board, comprising the steps of:
supplying a panel,
printing a substance onto the panel in a predefined pattern for creating an elevation on the panel at the predefined pattern, wherein said substance comprises a liquid and a powder, the substance is printed onto the panel by printing the liquid onto an initial upper surface of the panel in said predefined pattern, and then providing the powder to the liquid,
heating the powder so that the powder is melted together into a single mass which is elevated above the initial upper surface of the panel, hence forming the floor board;
wherein the predefined pattern substantially corresponds to a decorative pattern present on the panel prior to printing of the substance;
wherein a camera recognizes the decorative pattern printed on the panel before arriving at a printing station for printing the substance.
