Abstract

A lumber is cross cut into thin sheets to have cross grain patterns, and defective sheets are patched with pieces obtained from the extra part of the original sheet for the holes produced due to nodes or other flaws. The sheets then are piled in layers with adhesive in between in the original order of cutting the sheets and pressed for adhesion into the original lumber form to be cut again in perepndicular to the original lumber form to be cut again in perpendicular to the original cutting direction and produce flawles cross grain sheets. With applications to flawed lumbers, the method icnreses the productibility of cross grain wood sheets to the effect of low production cost.

본 발명은 주로 가구의 표면에 접착하여 원목의 자연스러운 미감을 얻도록 하는 박판(薄板)상의 판목(板目)무늬목에 관한 것으로, 무늬목의 모재가 되는 월라트(Walnut), 느릅나무(Elm), 로즈우드(Rosewood), 에보니(Evony), 만소니아등의 원목 내층에 갈라짐(crack)이나 옹이(knob) 또는 좀구멍(Moth hole)등의 결함이 있더라도 정척(正尺)의 무늬목을 얻을수 있도록 함과 동시에 완성된 무늬목에 파형굴곡이 발생되지 않도록 한것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to sheet wood veneers that adhere to the surface of furniture to obtain a natural aesthetic of solid wood, and include Walnut, Elm, Even if there are defects such as cracks, knots, or tooth holes in the inner wood of Rosewood, Ebony, Mansonia, etc. At the same time, the curved veneer does not occur in the finished veneer.

종래에는 원목을 가공하여 천연의 판목(板目)무늬목을 얻기 위하여 먼저 무늬목의 폭이 일정하도록 원목단면상의 상하좌우의 곡면을 절단하고 단면과 수직이 되는 방향으로 얇게 절단하여 무늬목을 얻도록 하였으나 원목의 내층에는 원목의 성장과정에서 형성된 갈라짐이나 옹이 좀구멍이 있기 마련이며 이러한 결함부분이 있는 무늬목은 사용할수 없으므로 절단하여 부정척(不正尺)으로 생산하거나 결함이 심한 경우에는 폐자재로 처리할수 밖에 없으므로 원목에서 얻어지는 무늬목의 수율은 고작 40%미만이었으며 따라서 원목을 전량 수입에 의존하는 우리의 실정으로 볼때 개인의 경제적 손실은 물론이고 외화를 불필요하게 낭비하게 되는 문제점이 있었고 또한 원목의 단면에서 볼때 부분적으로 재질자체의 경도차이가 필연적으로 발생하는 것이어서 절단해낸 무늬목에 파형굴곡이 생겨 품질을 저하시키는 원인이 되었던 문제점이 있었다.Conventionally, in order to obtain natural wood veneer by processing solid wood, first, the top, bottom, left and right curved surfaces of the wood section are cut so that the width of the veneer is constant, and thinly cut in the direction perpendicular to the cross section to obtain the veneer. In the inner layer of wood, cracks or knots formed during the growth of wood have some holes, and the patterned wood with these defects cannot be used, so they can be cut and produced in inaccurately or disposed of as waste if severe defects occur. Therefore, the yield of wood veneer is less than 40%. Therefore, in our situation of solid wood depending on imports, there is a problem of unnecessary waste of foreign currency as well as individual economic loss. As a result, the hardness difference of the material itself There was a problem that caused a wave form bend in the cut wood veneer caused the quality degradation.

본 발명은 이상에서 살펴본 바와같은 종래의 판목 제조방법이 안고 있는 문제점을 해결하기 위한 것으로 이를 첨부된 예시도면에 따라 상세히 설명하면 다음과 같다.The present invention is to solve the problems of the conventional wood block manufacturing method as described above described in detail according to the accompanying drawings as follows.

먼저 종래의 제조방법을 도면에 의하여 살펴보면 제 1(a)도에 보인 바와같이 원목(1) 단면상의 수직방향으로 곡면을 잘라내고 난후 제 1(b)도에 보인 바와같이 좁은 간격으로 절단하여 천연의 판목 무늬목을 얻게 되는 것인데 본 발명에서는 제 1(a)도, 제1(b)도와 같이하여 얻은 부판(2)인 무늬목에 갈라짐이나 옹이, 좀구멍등의 결함부분(6)을 펀칭머신(puching machine)으로 따낸후 원목 구입시로부터 존재하는 여유부분(4)에서 상기 결함부분(6)과 동일한 형상으로 따내어 결함부분(6)에 넣고 접착제(5)를 발라 접착하는 과정으로 결함부분(6)을 모두 보완한후에 부판(2)들을 제 1(b)도에서와 같은 순서로 접착제를 발라 재접착하여 제 3 도에 보인 바와같이 프레스(7)로 일정시간 가압하면, 가압공정이 끝난후에는 통풍성이 양호한 장소에 일정시간 방치하여 건조한다.First, as shown in the drawing, the conventional manufacturing method cuts the curved surface in the vertical direction on the cross section of the wood (1) as shown in Fig. 1 (a), and then cuts it at narrow intervals as shown in Fig. 1 (b). In the present invention, the wood chip veneer of the present invention is obtained by punching a defect part 6 such as cracks, knots, and pores in the veneer (2) obtained in the same manner as in the first (a) and the first (b). After pruning with a puching machine) from the purchase of the solid wood (4) to remove the same shape as the defective part (6) and put in the defective part (6) by applying an adhesive (5) to the defective part ( 6) After supplementing all the subplates 2 in the same order as in Fig. 1 (b) by re-adhesive and pressurized with a press (7) for a certain time, as shown in Fig. 3, after the pressing step is finished After drying for a certain period of time in a place with good ventilation.

건조가 끝난후에는 제 4 도에 보인 바와같이 부판(2)의 접착방향에 수직으로 절단도(8)로서 절단하면 제 5 도에 보인 바와같은 판목의 무늬목(9)을 얻을수 있게되는 것인데 이상과 같이하여 본 발명에서는 종래 방법에 의한 판목의 무늬목과 동일한 자연 그대로의 원목의 미감을 얻을 수 있으면서도 결함부분에 접착된 여유 부분은 그 부분 자체가 매우 얇은 것일 뿐만 아니라 접착후의 가압공정등에 의하여 외관상 여타부분과의 식별이 전혀 불가능할 정도로 결함부분이 제거되는 것이고 접착공정 및 가압공정등에 의하여 원목 단면상의 부분적인 재질의 경도 차이에 따른 파형굴곡을 제거할수 있게 되는 것이어서 이와같이 하여 본 발명은 종전의 방법에 의한 판목의 무늬목과 같은 원목의 미감을 살릴수 있음은 물론이고 옹이나 좀구멍, 갈라짐등의 치명적인 결함을 보수하여 부정척의 발생을 막을수 있으므로 종래의 판목무늬목 제조방법에 비하여 수율을 배가시킬수 있으며 따라서 생산자의 경제적 부담을 덜고 원목을 수입하는데 소요되는 외화를 대폭 절감할수 있는 것이고 무늬목에 파형굴곡이 형성됨을 방지할수 있어서 제품의 품질을 대폭 향상시키고 고급화할수 있게되는 것이다.After drying, as shown in FIG. 4, when cut as the cutting diagram 8 perpendicular to the bonding direction of the subplate 2, the wood veneer 9 can be obtained as shown in FIG. In addition, in the present invention, while obtaining the aesthetic of the same natural wood as the wood veneer according to the conventional method, the marginal part bonded to the defective part is not only very thin but also other parts in appearance by the pressing process after bonding. The defect is removed to such an extent that it is impossible to identify and it is possible to remove the corrugation bending caused by the difference in hardness of the partial material on the wood cross section by the bonding process and the pressing process. Thus, the present invention is a wood block by the conventional method. Not only can the wood's aesthetics, such as wood veneer, be saved, but also fatalities such as knots, burrs, and cracks As it can prevent the occurrence of inaccurate by repairing the defects, it can double the yield compared to the conventional method of manufacturing the wood veneer, thus reducing the economic burden on the producer and greatly reducing the foreign currency required to import the wood, and the wave bend on the veneer is formed. It is possible to greatly improve and enhance the quality of the product.
