Abstract

Claims (22)

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 in said heating step an entirety of the panel including the substance is placed in a heated environment;

wherein the liquid evaporates during the step of heating the powder;

wherein the predefined pattern substantially corresponds to a decorative pattern present on the panel prior to printing of the substance;

wherein a camera is arranged to recognize the decorative pattern printed on the panel before arriving at a printing station for printing the substance.

2 . The method according to claim 1 , wherein the powder is spread uniformly over the panel.

3 . 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.

4 . The method according to claim 3 , wherein the second portion of the powder is removed by suction.

5 . The method according to claim 1 , wherein the maximal thickness of the substance after curing lies between 5 and 1000 μm.

6 . 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.

7 . The method according to claim 1 , wherein the step of printing is digitally controlled.

8 . The method according to claim 1 , 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 after heating said panels are cooled before storing.

13 . The method according to claim 1 , wherein the powder comprises wear resistant particles.

14 . The method according to claim 1 , wherein the substance is printed beside a predetermined portion of the predefined pattern to form a depressed portion.

15 . The method according to claim 1 , wherein the decorative pattern is a wood or stone pattern.
