Mittellage für SperrholzMiddle layer for plywood

Sie Erfindung "bezieht sich auf Sperrholz, vorzugsweise Sperrplatten, und bezweckt eine "billige und einfache Herstellung der dazu erforderlichen Mittellage, "bei der der Holzverbrauch gering ist, die ein entsprechend geringes Gewicht aufweist und trotzdem gute Pestigkeitseigenschaften "besitzt.The invention "relates to plywood, preferably plywood, and aims at a "cheap and simple production of the necessary middle layer," in which wood is used is low, which has a correspondingly low weight and still has good pestibility properties ".

Es sind Mittellagen bekannt, die nur aus entsprechend angeordneten Pappstreifen bestehen. Diese Mittellagen besitzen jedoch wegen der Labilität der Pappe keine Festigkeit und ergeben infolge ihrer ungünstigen Fläche leicht Perverbindungen beim Aufleimen der Decklagen. Es sind auch Mittellagen bekannt, bei denen abwechselnd gestreckte mit gewellten Furnierbahnen aneinandergeleimt sind. Solche Mittellagen erfordern jedoch einen grossen Arbeitsaufwand und teuere Spezialeinrichtungen.There are middle layers known that only from appropriately arranged Consist of cardboard strips. However, because of the instability of the cardboard, these middle layers have no strength and result in them Due to their unfavorable surface, they can easily be joined when the top layers are glued on. There are also middle layers known in which Alternating stretched and corrugated veneer strips glued together are. However, such middle layers require a great deal of work and expensive special equipment.

Di^Mittellage nach der Erfindung schaltet diese Hachteile aus. Sie benötigt wenig Holz und besitzt durch ihren Aufbau eine hohe Festigkeit, gute Verleimfähigkeit mit den Decklagen und kann mit einfachen Mitteln hergestellt werden. Erreicht v?ird dies erfindungsgemäss dadurch, dass die Mittellage aus flachen hochkantstehenden mit Abstand nebeneinanderliegenden Holzleisten besteht und die gebildeten Hohlräume mit geeigneten leichten und billigen Füllstoffen ausgefüllt sind, die die Holzleisten gleich zeitig stützen.Di ^ middle position according to the invention switches off these Hachteile. It requires little wood and, thanks to its structure, has high strength, good gluing properties with the top layers and can with simple means. This is achieved according to the invention in that the middle layer consists of flat standing on edge with spaced adjacent wooden strips and the cavities formed with suitable light and cheap fillers are filled that support the wooden strips at the same time.

Nach einem weiteren Merkmal der Erfindung kann an den Enden der Mittellage der Füllstoff durch Holzeinlagen ersetzt werden, so dass die fertige Platte an den Stirnenden eine natürliche Hirnholzkante aufweist und sich ein nachträgliches Anlegen einer festen Eante erübrigt. Dadurch können beliebige Konstruktionselemente wie Dübel, ledern usw. angebracht werden. Diese besitzen dann eine organische Verbindung mit der ganzen Platte was mit besonderen Einfassleisten, die bei Füllplatten beim Verleimen mit den Decklagen angelegt werden, nie erreicht wird.According to a further feature of the invention, at the ends of the The middle layer of the filler can be replaced by wooden inlays, so that the finished panel has a natural end-grain edge at the front ends and a subsequent creation of a fixed Eante is unnecessary. This allows any construction elements such as dowels, leather, etc. are attached. These then have an organic connection with the entire plate which is never achieved with special edging strips that are applied to the top layers of filler panels when they are glued.

Ausführungsbeispiele der Erfindung sind in der Zeichnung d argestellt. Hier zeigen:Embodiments of the invention are shown in the drawing. Show here:

Pig. 2 in schaubildlicher Darstellung eine abgewandelte Mittellage mit aufgelegten Decklagen.Pig. 2 a modified representation in a diagrammatic representation Middle layer with applied top layers.

Die Mittellage nach Fig. 1 besteht aus flachen Holzleisten oder -streifen a, die hochkant stehen und mit einem gewissen Abstand nebeneinanderliegen. Die Holzleisten besitzen eine Höhe, die sich nach der Stärke der zu fertigenden Platte richtet. Zweckmassig sind die leisten bereits in Länge der herzustellenden Sperrholzplatte zugeschnitten oder werden als kurze Einzelstücke so gegeneinander geschoben, dass sich die Pertiglänge ergibt. Die von den Holzleisten eingeschlossenen Bäume sind mit einem Füllstoff, beispielsweise mit einem geeigneten Schaumstoff b, so ausgefüllt, dass dieser die leisten stützt. Als Füllstoff kann auch jedes andere Material, z.B. Wellpappe od.dgl-, gewählt werden. Der Füllstoff und die Holzleisten können lose nebeneinanderliegen oder miteinander verklebt, verleimt oder verheftet sein. Die so hergestellte Mittellage wird durch Verbindung mit Decklagen zu einer Sperrholzplatte vereinigt. Ein Teil einer solchen Sperrholzplatte ist in lig. 2 dargestellt. BeiThe middle layer according to Fig. 1 consists of flat strips of wood or -strips a, which stand upright and lie next to each other with a certain distance. The wooden strips have a height that depends on the thickness of the panel to be manufactured. Appropriate are the strips already cut to the length of the plywood sheet to be produced or are made as short individual pieces pushed against each other so that the finished length results. The trees enclosed by the wooden strips are with one Filler, for example with a suitable foam b, filled in so that it supports the strips. As a filler Any other material, e.g. corrugated cardboard or the like, can also be selected. The filler and the wooden strips can lie loosely next to each other or glued, glued or stapled together. The middle layer produced in this way becomes through connection combined with top layers to form a plywood panel. Part of such a sheet of plywood is in lig. 2 shown. at

dieser Ausführung sind die Zwischenräume zwischen den Holzleisten a mit senkrecht stehender Wellpappe To, die die Höhe der Holzleisten aufweist, ausgefüllt. Der von der Wellpappe gebildete !Füllstoff erstreckt sich hierbei nicht "bis zu den Enden der Leisten, sondern lässt jeweils einen Raum frei, in den ein passendes Holzstück c eingesetzt ist, so dass nach dem Aufbringen der Decklagen d die fertige Platte an den Stirnflächen eine geschlossene Holzkante aufweist.this version are the spaces between the wooden strips a with vertical corrugated cardboard To, which is the height of the wooden strips, filled.
