Abstract
The present invention relates to a method for the manufacture of a lumber element comprising at least one outer surface, at least one edge surface and at least one outer corner. The method comprises steps to round off the outer corner and to provide it with grooves comprising parallel ridges (13) and tracks (14) in the grain direction of the lumber to improve the paint-absorbing ability of the surface. The invention relates also to a lumber element comprising at least one outer corner which is provided with such grooves.
Claims14
A method for the manufacture of a lumber element comprising at least one outer surface, at least one edge surface and at least one outer corner wherein the outer corner is rounded off and provided with at least one groove comprising parallel ridges and tracks in the grain direction of the wood to improve the paint-absorbing ability of the surface.
A lumber element comprising at least one outer surface, at least one edge surface and at least one outer corner wherein the outer corner is rounded off and provided with at least one groove comprising parallel ridges and tracks in the grain direction of the lumber element to improve the paint-absorbing ability of the wood.
A method for the manufacture of a lumber element comprising the steps,
- sawing the lumber element in a raw condition;
- drying the lumber element, by which the same obtains deformation in such a way that a heart side of the same becomes convex-shaped while a sapwood side becomes concave-shape
- accentuating the concave form of the sapwood side through a removal of material by concave machining a central area of the sapwood side;
- rounding the outer corners of the heart side of the lumber element;
- and
- grooving the heat side and outer corners of the lumber element in the grain direction of the wood to improve the paint-absorbing ability of the surface.
