In a method for producing a three-dimensionally flexurally deformable surface element (3D surface element) from wood or wood composite material, a workpiece made of wood, layered wood or a composite of wood and one or more further surface materials is used, its thickness being greater, in particular at least 5% greater, than the thickness of the 3D surface element to be produced. Narrow grooves spaced apart from one another are introduced into the workpiece, wherein the groove depth is in each case greater than or equal to the thickness of the 3D surface element and less than the thickness of the workpiece. The portion of the workpiece which exceeds the thickness of the 3D surface element to be produced is then separated from the remaining 3D surface element or otherwise processed such that there is at least temporarily no solid cohesion of the areas separated by grooves and the areas of the workpiece separated by grooves are fixed to each other and/or to a support by a transverse bond prior to, during or after separation from the workpiece, wherein at least two adjacent grooves, in particular all of the grooves, are introduced into the workpiece in such a way that at least sections exhibit an irregular undulation and/or contiguous rectilinear sections extending in different directions in a plan view of the workpiece.
In a method for producing a three-dimensionally bendable surface element (3D surface element) from wood or wood composite material, a workpiece made of wood, plywood or a composite made of wood and one or more further surface materials is used, the thickness of which is greater than, in particular at least 5% greater than, the thickness of the 3D surface element to be produced. Narrow grooves spaced from one another are made in the workpiece, wherein the depth of the groove in each case is greater than or equal to the thickness of the 3D surface element and smaller than the thickness of the workpiece. Subsequently, that portion of the workpiece which exceeds the thickness of the 3D surface element to be produced is separated from the remaining 3D surface element or is treated in such a way that there is at least temporarily no firm cohesion between the areas separated by grooves, and that the areas of the workpiece that are divided from one another by grooves are fixed to one another and/or to a support by a transverse bond before, during or after the separation from the workpiece, wherein at least two of the grooves, which are adjacent, in particular all of the grooves, are made in the workpiece in such a way that, in a plan view of the workpiece, said grooves at least partially have an irregular undulation and/or contiguous rectilinear sections that extend in different directions.

The invention relates to a method for producing a decorative wood surface in the form of a planar veneer with a thickness of less than 1 mm, preferably 0.5 to 0.6 mm, having at least the steps (A) to (E): (A) mixing cut planar veneer pieces, each upper face or lower face of which has a surface area ranging from 200 mm2 to 2000 mm2, wherein each of the veneer pieces has a thickness of less than 1 mm, preferably ranging from 0.5 mm to 0.6 mm; (B) gluing the mixed veneer pieces; (C) arranging the glued veneer pieces in order to form a layer which has a thickness of up to 15 mm; (D) pressing the glued veneer pieces arranged in the layer in order to form a board with a board thickness of less than 6 mm; and (E) grinding the board until the planar veneer produced during the grinding process has a thickness of less than 1 mm, preferably ranging from 0.5 mm to 0.6 mm.
