[0001] The invention relates to the lumber master longitudinal axis at different angles to the (1) is cut. The angle for master longitudinal axis (1) 15 (4) can be between 75 degrees and (3).

[0002] Normally Processing logs (6) as precisely as possible along the master longitudinal axis (1) to such as planks sawing products, planks, posts, prisms or veneers.

[0003] It is also known that wood transversely to the log axis that is, at an angle of 90 degrees to the log axis (2), for example, as cut and is used as end grain is brain timber flooring.

[0004] Furthermore, is also known that in actual fact the form of a tree trunk or the notch angle with respect to its longitudinal axis during its longitudinal incision. Forcibly annual ring situation it is achieved a certain angle. This angle is 10 degrees but usually exceed (5) not substantially. This concerns [...] logs, particularly in the area of so-called root approaches. This is an unintended effect of the usually by milling off exactly this problem areas is eliminated.

[0005] wood parts, prepared according to this invention at an angle of between 15 and 75 degrees by default are cut to the longitudinal axis, in accordance with the claim 1 and 2.

[0006] in the following text are referred to as cross section woods These new wood parts.

[0007] a surprising new and characteristic claim 2 this cutting direction is produced in accordance with the sectional view, in other words a certain sequence of the annual rings, [...]half rift sample than that is is reminiscent of a, but a more or less bent annual ring sample, with annual rings in the width drawn, the appears at Rift-or half rift sample is uncommon, or only when [...].

[0008] Surprisingly is also that as beech structural-poor wood, maple or birch not only a new sectional view, but have a significantly differentiated wood design, the they lack in conventional longitudinal cuts entirely.

[0009] The according to the invention can be produced with all conventional surface treating agent for wood acted on wood parts. These are especially Paints, mordant, colorant, natural resins, synthetic resins, bleach, wood modification substances, substances for the pH change, waxes, oils or tanning agents.

[0010] according to the invention differs substantially from conventionally cut surface treatment of the wood parts but Thesawing products. The wood surface treatment means is any substantially increased absorption capacity. These seems to that most substances Indent [...] deeply into the wood, and together with the a deep, intimate connection therewith. So it is surprisingly possible to color or to load wood parts over the entire cross-section for example with tanning agents, what is conventionally produced at lumber parts hardly possible.

[0011] A effect is this excessive substance admission, with larger layer thicknesses that these wooden parts also can be made translucent.

[0012] But it is also more difficult to achieve a certain layer thickness of a substance on the wood, which is painted wood surfaces usually is desired. Here one can manage with a multilayer A coating structure and the corresponding viscosity.

[0013] Contrary to the experience in the modification of wood such as spruce it is now possible also [...] these types of wood with the most different substances to load, therefore to improve their performance properties significantly and therefore to modify.

[0014] A desired side effect of this julienne it is also that the hardness, unlike from longitudinal cuts prepared wooden parts is increased substantially.

[0015] 3 the preparation may take place either the wood parts thereby claim In accordance with the principle of the invention, a band saw is clamped so that a log in that the cutting angle of 15 to 75 degrees to the longitudinal axis of the tree is achieved in one operation.

[0016] 4 would be an alternative type of manufacture claim According to, first engages the Gang saw posts, planks or prisms produce, which is subsequently applied to a circular or band saw in a certain angle to the longitudinal axis, of between 15 and 75 degrees may be selected, are cut.

[0017] The thickness of the thus produced can vary strongly cross section woods, it will be but usually between 1 and 30 millimeters.

[0018] But it is quite possible that by knives in the earlier specified angle to the log axis is generated with the corresponding a veneer woodcut picture.

[0019] 5 be adopted in accordance with this invention produced in accordance with the claim to the wood parts above all used to be adhered to other conventional wood parts or wooden materials. These especially therefore, because a portion of the mechanical characteristic values are reduced as compared to conventionally produced wooden parts. bending break characteristics This occurs particularly. Therefore the insert but limits for constructive purposes is possible.

[0020] For for example, multi-layer structural wood but this seems parquets produced in accordance with the invention are particularly suitable.
