上記ボード6の上面はベニヤ板を成すフィルムTによって覆われている。フライ ス盤によって、後にケーシング縁部を成す個所がボード6に形成される。この個 所には、フィルム7まで到達しながらもフィルム7を損承しない複数の溝8がフ ライス削シによって形成されている。その結果、溝8の間にはボード6の材料か ら成るウェブ9が残されておシ、これらウェブ9の高さはボード6の厚さよシも 小さいか、又はそれと同じでおる。次いで、溝8内へ接着剤10が充填される。The upper surface of the board 6 is covered with a film T forming a plywood board. fly By means of the platen, the points which will later form the casing edge are formed on the board 6. this piece There are a plurality of grooves 8 that reach the film 7 but do not damage the film 7. It is formed by cutting rice. As a result, between the grooves 8 there is material of the board 6. The height of these webs 9 is equal to the thickness of the board 6. It's smaller or the same. Next, the adhesive 10 is filled into the groove 8 .
この目的のためにボード6が以下のように形成された装置内へ配置される。即ち この装置によって、ボード6は接着剤10が菫付された後にすぐに湾曲され、接 着剤10が硬化するまでの間、適当な位置に固定保持される。この場合、接着剤 10の硬化は数秒で行われる。このようKして、溝8によってまず著しく弱めら れたボード6が、再び7ライス削シされていないボードとほぼ同程度に堅固にな る。さらに複数の接着剤の紹合わせKよる接着方法も考えられるが、この場合す ぐに硬化する接着剤によって予固着が行われ、ゆつくシと硬化する第2の接着剤 によって最終固着が行われる。異なる作用を行う2つの接着剤によるこのような 接着方法は、DE−PS第2927182号明細書に記載されている。For this purpose, a board 6 is placed into a device constructed as follows. That is, With this device, the board 6 is bent immediately after the adhesive 10 is applied, and the board 6 is bonded. The adhesive 10 is fixed and held at an appropriate position until it hardens. In this case, the adhesive Curing of 10 takes place in a few seconds. In this way, the groove 8 first significantly weakens the The board 6 that has been milled is now almost as solid as the unmilled board 7. Ru. Furthermore, a bonding method using multiple adhesives can be considered, but in this case, all Pre-fixing is done with an adhesive that hardens quickly, and a second adhesive that hardens slowly. Final fixation is performed by This type of adhesive has two adhesives that perform different actions. The bonding method is described in DE-PS 2927182.
溝8の特別な構成によって、ボード6の湾曲時に滑らかな丸味を有する縁部が自 動的に形成される。従って、DE−O8第2114364号明細書よシ公知の、 ボードから成るケーシングのこのような製法は、石膏ファイバボード及びセメン ト結合された木材チップボードの場合でも有利に適用される。伺加的に示された フィルム11は、ケーシング縁部の製造プロセスにおいてフィルム1を一時的に 固定するのに役立ってシシ、その後再び取外される。Due to the special configuration of the grooves 8, smooth rounded edges are created automatically when the board 6 is bent. Dynamically formed. Therefore, the method known from DE-O 8 2114364, This method of manufacturing casings made of board is suitable for gypsum fiberboard and cement It is also advantageously applied in the case of wood-bonded wood chip boards. shown in a concise manner Film 11 temporarily replaces film 1 during the manufacturing process of the casing edge. It helps to fix it and then it is removed again.
