Description
Verfahren zum Herstellen von Mittellagen für Sperrholz, die aus belegtem Wehfurnier bestehen Die Erfindung betiifft ein Verfahren zum Herstellen von Mittellagen für Sperrholz, die "aus belegtem Weltfurnier bestehen.Process for the production of middle layers for plywood from coated Worn veneers consist The invention relates to a method for producing central layers for plywood that "consists of covered world veneer.
Bekannt sind Mittellagen für Sperrholz aus Wellpappe und Wellfurnieren. Die. Wellfurniermittellagen sind mit einem hochglänzenden Metallbelag versehen, um eine gute Wärmeisolierung derartiger Sperrholzplatten zu erreichen. Es ist ferner bekannt, Furniere zu wellen und auf eineroder beiden Seiten durch Aufkleben von Metallfolien, Gewebebahnen u. dgl. zu versteifen. Es ist auch bekannt, flache Holztapeten dadurch herzustellen, daß dünne, frisch geschälte Furniere nach dem Aufbringen eines Klebemittels mit einer Bahn aus Papier, Pappe u. ä. vereinigt werden. Die Vorrichtungen zum Herstellen von Weltfurnier sind allgemein bekannt.Middle layers for plywood made of corrugated cardboard and corrugated veneers are known. The. Corrugated veneer middle layers are provided with a high-gloss metal coating, to achieve good thermal insulation of such plywood panels. It is further known to corrugate veneers and on one or both sides by gluing To stiffen metal foils, fabric sheets and the like. It is also known to be flat wooden wallpaper by producing thin, freshly peeled veneers after applying a Adhesive can be combined with a sheet of paper, cardboard and the like. The devices for making world veneer are well known.
Die Erfindung besteht dem Bekannten gegenüber darin, zum Herstellen von Mittellagen für Sperrholz frisch geschältes Furnier beidseitig mit Papierbahnen zu hinterlegen und dabei gleichzeitig zu wellen und zu trocknen. Durch das erfindungsgemäße Verfahren werden gegenüber den bekannten. Verfahren wesentliche Vorteile erreicht. Man hatte es zwar verstanden, Furniere zu wellen, es war aber nicht gelungen, die Wellung des Furniers auf einfache Weise in Fnem zu halten bzw. dies gleichzeitig bei der Herstellung so zu gestalten, daß die Furnierwellen in der ihm zugedachten Form bleiben. Es war auch nicht möglich, das gewellte Holz ohne Aussplitterung, Reißen u. dgl. zu sägen.The invention consists in relation to the known to manufacture from middle layers for plywood freshly peeled veneer on both sides with paper webs to deposit and at the same time to curl and dry. By the invention Procedures are opposite to the known. Process achieved significant advantages. They knew how to curl veneers, but they hadn't succeeded To keep the corrugation of the veneer in a simple manner or at the same time to design during production so that the veneer waves in the intended for him Stay in shape. It was also not possible to cut the corrugated wood without splintering, Sawing tears and the like.
Das Herstellen der Wellholzbahn erfolgt derart, daß frisch geschälte Furniere beidseitig kaschiert, d. h. mit Papier belegt werden. Diese Kaschierdecken werden am Furnier angeklebt. Man- kann dazu beispielsweise ein Silicat als Leim verwenden. Diese kaschierte Furnierbahn durchläuft dann eine .-an sich bekannte Riffelröhrenanlage, deren am Furnier arbeitende Teile in bekannter. Weise geheizt werden.The production of the corrugated wood sheet is done in such a way that freshly peeled Veneers laminated on both sides, d. H. be covered with paper. These laminated blankets are glued to the veneer. You can use a silicate as glue, for example use. This laminated veneer web then runs through a known one Corrugated tube system, the parts working on the veneer in well-known. Way heated will.
Zur Verarbeitung kommen frisch geschälte Furnierbahnen, die parallel zur Holzfaserrichtung der Vorrichtung zum Wellen zugeführt werden, wobei sie, wie schon beschrieben, gleichzeitig kaschiert und getrocknet werden.Freshly peeled veneer strips are used for processing fed to the direction of the wood grain of the device for corrugating will, as already described, they are laminated and dried at the same time.
Aus der beiliegenden Zeichnung sind erfindungsgemäße Mittellagen ersichtlich, und zwar zeigt Abb. i eine solche Mittellage mit Deckfurnieren, Abb. 2 eine Mittellgge in Wabenform.The central layers according to the invention can be seen in the accompanying drawing, namely Fig. i shows such a middle layer with face veneers, Fig. 2 a middle layer in honeycomb form.
In den Figuren bedeuten a Well.furnierbahn, b Papierbahnen und c Deckfurniere. Die frisch geschälte Furnierbahn a wird mit ihrer Holzfaserriehtung parallel Du den Achsen der Riffelwalzen in eine bekannte Vorrichtung zum Herstellen von Weltfurnier eingeführt. Die beiden Papierbahnen b werden gleichzeitig mit der Furnierbahn a in die Weltvorrichtung eingeführt, nachdem sie in bekannter Weise mit Leim bestrichen worden sind.In the figures, a denotes corrugated veneer sheet, b denotes paper sheets and c denotes face veneer. The freshly peeled veneer sheet a is parallel to you with its wood fiber alignment the axes of the corrugating rollers in a known device for the production of world veneer introduced. The two paper webs b are simultaneously with the veneer web a introduced into the world device after being coated with glue in a known manner have been.
Die so hergestellten Weltfurniere mit beiderseitigem Papierbelag können nun in an sich bekannter Weise. mit Deckfurnieren versehen wenden, oder sie werden zu einem Block verleimt und quer zu den entstandenen Hohlröhren in der gewünschten Mittellagendicke zersägt.The world veneers produced in this way with paper covering on both sides can now in a manner known per se. veneered, or they will Glued to a block and transversely to the resulting hollow tubes in the desired Sawn middle layer thickness.
Man erhält so Scheiben mit Wabenfbrm, die, wie Abb. 2 zeigt, ebenfalls als Mittellagen verwandt werden. Das fertiggestellte Weltfurnier ist gegenüber Feuchtigkeitseinflüssen fast unempfindlich, platzt und schwindet nicht und fäßt sich Aeichx bearbeiten. So besteht beim Sägen des ei-'findungsgemäß hergestellten Weltfurniers b'zw. des mit ihm als Mittellagen hergestellten Sperrholzes keine Gefahr des Splitterns.This gives panes with a honeycomb shape, which, as Fig. 2 shows, also can be used as middle layers. The finished world veneer is resistant to the effects of moisture almost insensitive, does not burst or shrink and can work on Aeichx. Thus, when sawing the world veneer produced according to the invention or. of plywood made with it as the middle layers no risk of splintering.
Das Wehfurnier und die hieraus herzustellenden Sperrholzpl?,tten mit Röhren- und Wabenform können sich nicht verziehen, und dadurch wild ein Werfen der Sperrholzplatten mit den erfindungsgemäßen Mittellagen vermieden. Von den vielseitigen Anwendungsmöglichkeiten solcher Sperrholzplatten seien nur die folgenden erwähnt: Bauteile auch für die Tropen, Verschalungen, Trennwände, Möbelbau, Türenbau, Verpackungszwecke und Fässer, Leichtbauten, Ausstellungsstände, Fxlmkulisgen und Bauten, Wochenendhäuser.The woof veneer and the plywood sheets to be made from it are also included Tubular and honeycomb shapes cannot warp, and thus wild throwing of the Avoid plywood sheets with the middle layers according to the invention. From the versatile Possible uses of such plywood panels are only mentioned as follows: Components also for the tropics, cladding, partition walls, furniture construction, door construction, packaging purposes and barrels, lightweight structures, exhibition stands, fxlmkulisgen and buildings, weekend houses.
