Description
Verfahren zum Herstel*#en,wdn Holzhohlkörpern Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Holzhohlkörpern unter Verwendung einer Form und eines durch Einführen von flüssigen oder gasförmigen Preßmitteln aufblähbaren elastischen Körpers. Bisher ist die Verleimung übereinandergewickelter mit Leim bestrichener Furniere bekanntgeworden, die durch Spreizung eines aus gegeneinanderverschiebbaren Sektoren bestehenden Kernes an die Wandung einer Hohlform gepreßt und unter diesem Druck verleimt werden. Nach diesem Verfahren sollen sich Hohlkörper von wenigen Zentimetern Durchmesser, z. B. Rohre, nicht herstellen lassen, weil der Platz für einen durch mechanische Mittel spreizbaren Kern fehlt. Biegsame und undurchlässige Membrane, die durch aufblähbaren Druck gegen die zu verleimenden Gegenstände angepreßt werden, sind an sich schon bekanntgeworden, aber nur zur Beleimung eines Gegenstandes mit Furnieren.Method for the production of wooden hollow bodies The invention relates refers to a method for producing wooden hollow bodies using a Form and one inflatable by introducing liquid or gaseous pressing agents elastic body. So far the glue has been wrapped with glue coated veneers become known, which can be displaced from one another by spreading a Sectors of the existing core pressed against the wall of a hollow mold and under this Pressure can be glued. According to this process, hollow bodies are said to be made up of a few Centimeters in diameter, e.g. B. Pipes, can not be produced because of the space for a core that can be expanded by mechanical means is missing. Flexible and impermeable Membrane that is pressed against the objects to be glued by inflatable pressure are already known per se, but only for gluing an object with veneers.
Das Wesen der Erfindung besteht darin, daß der zwischen der Form und dem elastischen Körper zu verleimende Werkstoff aus mehreren Lagen übereinandergewickelter dünner Sp.errholzplatten besteht.The essence of the invention is that between the form and The elastic body to be glued material consisting of several layers wound one on top of the other consists of thin wooden panels.
Das Verfahren wird in folgender Weise ausgeübt: Eine oder mehrere mit Leim versehene dünne Sperrholzplatten werden um einen elastischen Körper herumgewickelt und mit ihm in eine ein- oder mehrteilige Hülse, welche die Form des gewünschten Hohlkörpers hat, eingeführt. Durch Einführen von flüssigem oder gasförmigem Preßmittel in den vom Hohlkörper umschlossenen elastischen Körper werden die Sperrholzplatten an die Hülsenwand gepreßt und unter diesem Druck verleimt. Nach Beendigung des Verleimungsprozesses werden die Hülse sowie der elastische Körper entfernt.The procedure is carried out in the following ways: One or more Glued thin plywood sheets are wrapped around an elastic body and with it in a one-piece or multi-part sleeve, which has the shape of the desired Hollow body has introduced. By introducing liquid or gaseous pressing agent The plywood panels are placed in the elastic body enclosed by the hollow body pressed against the sleeve wall and glued under this pressure. After finishing the gluing process the sleeve and the elastic body are removed.
Auf diese Weise kann man Holzhohlkörper von sehr kleinem Durchmesser herstellen. Die beiliegende Zeichnung gibt eine Erläuterung, rechts im Längsschnitt, links .im Querschnitt. a ist die äußere Form, welche auseinandergenommen werden kann, b sind mehrere Sperrholzplattenlagen, c ist der aufblähbare Kern und d ist das Einführende für das Pre13.nfittel.In this way, hollow wooden bodies with a very small diameter can be produced produce. The accompanying drawing provides an explanation, on the right in longitudinal section, left. in cross section. a is the outer shape which will be taken apart can, b are multiple layers of plywood, c is the inflatable core, and d is the introductory part for the Pre13.nfittel.
