Abstract

PURPOSE:To obtain fancy veneer having a special grain pattern different from a usual grain pattern by using raw wood or rectangular timber whose grain is forcibly distorted in an arbitrary direction by pressure molding as a material and cutting this material to form veneer. CONSTITUTION:Raw wood 1 or rectangular timber is subjected to heat treatment to be softened and subsequently subjected to pressure molding using a mold 2 having a special molding surface 2a to form raw wood 1'a or rectangular timber whose grain is forcibly distorted in an arbitrary direction as a material. This material is cut by a slicer or a veneer race to form fancy veneer 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veneer used as a surface decorative material for wood products and the like and a method for producing the same.

[0002]

2. Description of the Related Art A conventional veneer is usually formed by slicing lumber into thin pieces using natural wood as it is. Such a veneer is often used as a surface decorative material for building interior materials, furniture cabinets, and other furnishings because a natural and beautiful wood grain pattern can be obtained.

[0003]

However, the wood grain pattern of the veneer can be obtained only for the tree of the material,
Normally, one tree is limited to two types, a grain pattern and a grain pattern. Therefore, a special tree must be used as a material to obtain an unusual wood grain pattern, but such a special tree is a rare value, and it is difficult to obtain it in large quantities at low cost. Products that require an almost uniform wood grain pattern finish due to overall uniformity and balance,
Especially in the case of system furniture, system kitchen, etc., a large amount of valuable raw wood is required to obtain a veneer with an approximate wood grain pattern, and there is a large amount of waste, resulting in high manufacturing costs and other unfavorable manufacturing problems. ..

The present invention has been made in view of such a conventional situation, and provides a veneer using a common tree as a material so as to obtain an unusual wood grain pattern, and a method for manufacturing the veneer. Is the subject.

[0005]

As a means for technically solving the above-mentioned problems, the present invention uses a raw wood or a square wood in which a wood grain is forcibly distorted in an arbitrary direction by pressure molding with a mold as a raw material. The gist is a veneer formed by cutting this material. Furthermore, the present invention is characterized in that raw wood or timber is softened by heat treatment, pressure-molded with a mold having a special molding surface, and then cut with a slicer or veneer lace to form a veneer. is there.

[0006]

[Operation] Since the wood grain of the raw wood is forcibly distorted by pressure molding with a mold, forming a veneer using this as a material gives a wood grain pattern with an appearance different from the usual grain pattern or grain pattern.

[0007]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a raw wood cut into an appropriate length, which is heat-treated by boiling in a boiling tank (not shown) to be softened. The heat treatment by boiling can be carried out in the same manner as the boiling treatment of the conventional rotary veneer log or sliced veneer flitch.

Next, the boiled raw wood 1 is simultaneously pressure-molded from four directions, up, down, left and right, by a mold 2 having a fold-corrugated molding surface 2a as shown in FIG. This molding condition is
It depends on the tree species of log 1, especially hardwood or softwood.
As shown in (c), a corrugated molding surface 1'b is formed on the surface of the raw wood 1 by the molding surface 2a of the mold 2, and the concentric circular grain (annual ring) 1a is bent and distorted into a substantially rectangular shape. Make the grain 1'a.

When the treated raw wood 1'pressurized in this manner is used as a material and applied to a veneer lace (not shown), the corrugated wood grain 1'a causes several pieces of wood to be produced as shown in FIG. A veneer 3 having a special wood grain pattern in which curves are gathered intermittently can be obtained. The normal veneer P formed from the untreated raw wood 1 has an ordinary wood grain pattern as shown in FIG. 6 (e), so that the wood grain pattern of the veneer 3 is remarkably different in appearance, and it seems to be the same kind of tree. Absent.

FIG. 2 shows an embodiment in which a square bar 4 is used instead of a log. After heat treatment by boiling as in the above, the mold 2 is used to press only from above and below. The corrugated surface 4'b is formed and the wood grain (annual ring)
4a is distorted to form a wavy grain 4'a.

When the processed square bar 4'compressed as described above is used as a raw material and applied to a slicer (not shown), the corrugated wood grain 4'a bends and bends as shown in FIG. The veneer 5 having a curved grain pattern is obtained. Ordinary veneer Q sliced from untreated timber 4
Has a grain pattern as shown in FIG. 4 (d), and thus has a significantly different appearance from the projecting plate 5.

FIG. 3 is an embodiment in which a square-shaped veneer is formed by using a square member 6. After heat treatment by boiling is performed as in the embodiment of FIG. 2, the mold 2 is used to apply heat from above and below. Press to form the corrugated surface 6'b, and also the wood grain (annual ring)
6a is distorted to form a corrugated wood grain 6'a, and a sliced plate 7 is formed by using this treated square timber 6'as a raw material and applying a slicer. In this case as well, it looks remarkably different from the normal grained veneer R.

FIG. 4 shows an embodiment in which the corrugated molding surface 8'b is pressure-formed along the lengthwise direction of the square bar 8 by a die after the square bar 8 is heat-treated. When the above is formed, a projecting plate 9 having a special grain pattern as shown in FIG. 6C or a projecting plate 10 having a special grain pattern as shown in FIG. The wood grain pattern of these special forms is also called Geji heather. Ordinarily obtained from the timber 8 is a veneer S having a grain pattern as shown in FIG. 5E or a veneer T having a grain pattern as shown in FIG. The appearance is so different that it is unlikely that they are the same type of tree.

When pressure molding is performed by the mold 2, the intervals and the variations in the arrangement of the annual rings are corrected almost uniformly, so that the grain pattern expressed by the lines of the annual rings when the sheet is formed into a veneer becomes approximately similar, and therefore It is possible to obtain a large number of similar wood-patterned veneer plates from the same material. Further, the pressure molding increases the density of the material, improves the strength, and makes it difficult to deform, so that the quality of the veneer can be improved.

[0015]

As described above, according to the present invention,
The raw wood or the timber that is pressure-molded by a mold to force the wood grain to distort in any direction is used as the material, and the veneer is formed by cutting this material, so a special wood grain pattern different from the normal wood grain pattern is used. A veneer can be obtained, and a large number of veneers with an approximate wood pattern can be obtained without waste. Therefore, a veneer with high added value can be obtained from ordinary tree species, and it is most suitable for products that require a nearly uniform wood grain pattern finish in terms of overall uniformity and balance, especially system furniture and system kitchens. Excellent effects such as simple manufacturing and low cost can be obtained.
