Description

Verfahren zur Herstellung von engen Röhren aus Holz. Enge Röhren aus Holz für musikalische Holzblasinstrumente, für hohle Spazierstöcke und Schirmstäbe herzustellen, ist an sich bekannt, und zwar :derart, daß :dünne Furniere in einer Rolle aufeinanidergewickelt werden. Sehr enge, widerstandsfähige Röhren lassen sich aber auf diese Weise nicht erzielen, da solche Furniere schon sehr dünn, z. B. o,i mm, sein müßten, um sich auf enge Durchmesser wickeln zu lassen. Die Erfindung bezieht sich nun auf ein Verfahren zur Herstellung von engen Holzröhren und besteht ,darin, @daß man Idas Gefüge einer Platte aus kreuzweise verleimten Furnieren zunächst in an sich für Holz bekannter Weise auflockert und solche @dadurch biegsam ausgestaltet, worauf alsdann erst :die Röhre aus ,der Platte z. B. in feuchtem Zustande .durch Biegung hergestellt wind.Method of making narrow tubes from wood. Tight tubes out Wood for musical woodwind instruments, for hollow walking sticks and umbrella sticks produce is known per se, namely: in such a way that: thin veneers in one Roll are wound onto each other. Very narrow, resistant tubes can be but not achieve in this way, since such veneers are already very thin, z. B. o, i mm, would have to be in order to be able to be wound to narrow diameters. The invention relates now focuses on a process for the production of narrow wooden tubes and consists in @ that Ida's structure of a plate made of cross-glued veneers is first in loosens up in a manner known for wood and thus makes it flexible, whereupon only then: the tube off, the plate z. B. in a damp state .by Bend made wind.

Es war bisher in ider Technik nicht möglich, Röhren aus Sperrholz mit einem verhältnismäßig engen Durchmesser, z. B. 2 cm und darunter, haltbar herzustellen, weil das Sperrholz, spätestens sobald es trocknete, platzte. Die Herstellung von Röhren .mit größerem Durchmesser aus verleimtem Furnier erforderte verhältnismäßig großen Kraftaufwand, da. .die Röhren in feuchtem Zustand über eine ,Form gebogen und alsdann unter Druck über ;dieser Form verleimt werden mußten.So far it was not possible with the same technique, tubes made of plywood with a relatively narrow diameter, e.g. B. 2 cm and below, durable to produce, because the plywood burst, at the latest as soon as it dried. The manufacture of Tubes with a larger diameter made of glued veneer required proportionally great effort, there. .the tubes are bent over a shape when they are wet and then under pressure over; this form had to be glued.

Röhren gemäß oder vorliegenden Erfindung sind insbesondere für Möbel und Dur Isolierung von Rohrleitungen auch für Druckleitungen als .Ersatz für Metallröhren geeignet. Das verleimte Furnier wird so biegsam ausgestaltet, @d'aß es sich auf enge Durchmesser, -z. B. i Abis 2 om, bequem von Hand biegen läßt, -indem idie Platte aus verleimten Furnieren zunächst in der in der Patentschrift 3o6417 .beschriebenen Weise mit chemischen Mitteln behandelt wird. @Gegebenenfalls kann man die Platte dann noch reit Chlorkalziumlösung tränken und zum Schluß noch eine C51- oder Fettimprägnierung ausführen. So hergestellte Röhren aus Sperrholz mit geringem Durchmesser und vieleckige Röhren mit geringer Qu erschnitisfläche sind besonders vorteilhaft zur Herstellung von Möbeln geeignet. Auch ,zur elektrischen oder termischen Isolation eignen sich derartige Sperrholzröhren wegen ihrer hohen Isolationsfähigkeit gut. Wenn man sie wasser- oder luftdicht oder feuersicher imprägniert, so sind sie in .der Lage, hohen Druck au's'zuhalten, und sind daher auch für Druckleitungen aller Art zu verwenden.Tubes according to or the present invention are in particular for furniture and Dur insulation of pipelines also for pressure lines as a replacement for metal pipes suitable. The glued veneer is designed to be so flexible that it rises narrow diameter, -z. B. i Abis 2 om, can be easily bent by hand, by i the plate made of glued veneers initially in the one described in patent 3o6417 Way is treated with chemical agents. @If necessary, you can use the plate then soak in calcium chloride solution and finally a C51 or grease impregnation carry out. So made tubes of plywood of small diameter and polygonal Tubes with a small cross-sectional area are particularly advantageous for production suitable of furniture. They are also suitable for electrical or thermal insulation such plywood tubes work well because of their high insulation properties. If you can If they are waterproof, airtight or fire-proof, they are able to achieve high Pressure must be maintained and are therefore also to be used for all types of pressure lines.

Die Zeichnung zeigt eine Aüsführungsform, und zwar Abb. leine Röhre aus Sperrholz in Ansicht, Ahb. 2 die keilförmige Verbindung der Stoßfuge ider Röhre im Schnitt, Abb. 3 zeigt eine Röhre für elektrische oder thermische Leitung, welche zeit Sperrholzisolationsmaterial verkleidet ist.The drawing shows an embodiment, namely Fig. Leine tube made of plywood in view, map. 2 the wedge-shaped connection of the butt joint in the tube in section, Fig. 3 shows a tube for electrical or thermal conduction, which time plywood insulation material is clad.

Die Röhre i der Abb. i besitzt .an ihrer Stoßfuge 2 an beiden Enden keilförmige Ab-Ischrägungen 3. Die Herstellung derartiger langer Keilflächen findet im trockenen Zustande, .in welchem j a idie Sperrnolzplatten zur Verfügung stehen, am besten durch Schleifen statt.The tube i in Fig. I has .an its butt joint 2 at both ends wedge-shaped bevels 3. The production of such long wedge surfaces takes place in the dry state, in which the plywood panels are available, best done by grinding.

In Abb. 3 ist das Leitungsrohr 14 für Abdampf aus Metall, eine elektrische Leitung o. dgl. idurch Sperrholzröhren 15 und 16 verkleidet, welche an ihrer Stoßfuge mit der Muffe 17, die :ebenfalls aus röhrenförmig gestaltetem Sperrholz besteht, überdeckt sind.In Fig. 3 the conduit 14 for exhaust steam is made of metal, an electrical one Line o. The like. I clad by plywood tubes 15 and 16, which at their butt joints with the sleeve 17, which: also consists of tubular plywood, are covered.

Zwischen !den Isolierröhren 15 und 16 der Abb. 3 und dem eigentlichen Leitungsrohr 14 kann natürlich auch durch zwischengeschobene Muffen (z. B. solche ider gleichen Ausführung, wie die außen angeordnete Muffe 17) noch eine Luftisolation gebildet werden.Between! The insulating tubes 15 and 16 of Fig. 3 and the actual Line pipe 14 can, of course, also be made by inserting sleeves (e.g. such in the same design as the sleeve 17 arranged on the outside, there is also air insulation are formed.
