Method of making a wavy wood element (B) from a wood element •(A), wherein the method comprises at least steps (H1) to (H4): •(H1) providing a wood element (A), which comprises fibers and lignin on or between said fibers; •(H2) heating the wood element (A) to a temperature which is sufficient to soften or melt at least a part of the lignin; •(H3) deforming the wood element heated in step (H2) such that a wavy wood element (B) is formed; •(H4) cooling the wood element deformed in step (H3); characterized in that the deforming in step (H3) is performed such that the ratio of the wave height to the thickness of the wavy wood element (B) equals or is more than 2:1; wherein the term “thickness” signifies the shortest distance between an upper side and the respective lower side of the wavy wood element (B), and the term “wave height” signifies the shortest distance between two imaginary planes which run in parallel to one another between which the wavy wood element (B) may be arranged such that the waves are positioned between said planes; and wherein the wood element (A) consists of unglued wood or unglued wood fibers.
Method of making a wavy wood element (B) from a planar or non-planar wood element (A), wherein the method comprises at least steps (H1) to (H4):
Method according to any one of the preceding claims, wherein the deforming in step (H3) is performed by means of a profile tool such that the wave of the wavy wood element (B) comprises one positive, respectively one negative half-wave, only.
Method according to any one of the preceding claims, wherein in step (H1) a wood element (A) is utilized, the fibers of which have a preferred direction, and the deforming in step (H3) is performed such that
Method according to any one of the preceding claims, wherein the ratio of wave height to thickness is in the range of equal or more than 2.0:1 to 30:1, or equal or more than 2.0:1 to 15:1, or 3:1 to 10:1, or 4:1 to 8:1, or 5:1 to 6:1.
Method according to any one of the preceding claims, wherein the thickness of the wavy wood element (B) is in the range of from 0.1 mm to 5 mm, and the wave height is in the range of from 1 mm to 20 mm;
Method according to any one of the preceding claims, further comprising at least one of the following steps (H3.1), (H3.2), (H3.3), (H5) and/or (H6):
Method according to any one of the preceding claims, wherein wood element (A) is a veneer.
Method according to any one of the preceding claims, wherein wood element (A) is an OSB chip having a length of more than 50 mm and a thickness of less than 2 mm.
Wavy wood element, the surface of which is at least partially coated with lignin, characterized in that the ratio of the wave height to thickness of the wavy wood element is 2:1 or is more than 2:1;
