Description

Verfahren zur Herstellung nahtloser Hohlkörper o. dgl. durch Pressung. Es ist bereits bekannt, Hohlkörper durch Pressung zu erzeugen. Hierbei werden je- doch -die Wandungen der Hohlkörper durch diese überlappende, gekrümmte Kantenstücke verbunden.Process for the production of seamless hollow bodies or the like by pressing. It is already known to produce hollow bodies by pressing. Here, however, the walls of the hollow bodies are connected by curved edge pieces which overlap them.

Gemäß der Erfindung werden Hohlkörper ohne Zuhilfenahme solcher Zwischenstücke, also tatsächlich aus einem Stück erzeugt, wobei als Ausgangsmaterial Flechtwerk aus irgendwelchen Faserstoffen, z. B. Schilfrohr, Weidenruten., Gräser, Stroh, dient. Wird auf ein derartiges Flechtwerk .beim Anliegen auf eine entsprechende Form mit einem Stempel o. dgl. ein Druck ausgeübt, so gibt das Flechtwerk allmählich nach und schiebt sich ganz von selbst in,die richtige und günstigste Lage zur Herbeiführung der gewünschten Endform.According to the invention, hollow bodies are made without the aid of such intermediate pieces, So actually made from one piece, with wickerwork as the starting material from any fiber, e.g. B. reeds, willow branches., Grasses, straw, is used. Is on such a wattle .beim on a corresponding shape with If a pressure is exerted on a stamp or the like, the wattle will gradually give way and pushes itself into the right and most favorable position for bringing about it all by itself the desired final shape.

Von besonderem Wert ist das Verfahren gemäß der Erfindung für Gebrauchszwecke, bei welchen mehrere übereinanderliegende Schichten Flechtwerk, @die an den Berührungsflächen mit Bindemitteln versehen sind, der Pressung unterzogen werden, da in diesem Falle in der Regel die nach außen. gelegenen Schichten einer stärkeren Beanspruchung unterworfen sind als die nach innen gelegenen, dem dadurch Rechnung getragen werden kann, daß man Idas Material für die nach innen bzw. nach außen liegenden Flechtwerkschichten entsprechend wählt.The method according to the invention is of particular value for purposes of use, in which several superimposed layers of wickerwork, @ those at the contact surfaces are provided with binders, are subjected to the pressing, as in this case usually the outward. layers are subjected to greater stress are as inwardly situated, which can be taken into account by the fact that one Idas material for the inner and outer layers of wickerwork chooses accordingly.
