Description

Verfahren zur Herstellung gekrümmter, dünnwandiger Hohlkörper aus Sperrholzplatten. Es ist bereits bekannt, zur Herstellung dünnwandiger Holzkörper aufgeweichte Sperrholzplatten um zylindrische Walzen zu wikkeln und gegen diese unter Verwendung eines Biegegürtels als Zwischenlage durch geheizte Walzen von außen anzudrücken. Nach diesem Verfahren lassen sich nur Rotationsformen mit einfachen Krümmungen herstellen.Process for the production of curved, thin-walled hollow bodies from Plywood panels. It is already known for the production of thin-walled wooden bodies Softened sheets of plywood wrap around and against cylindrical rollers using a bending belt as an intermediate layer through heated rollers from the outside to press. This method can only be used to produce rotational molds with simple Making curvatures.

Durch das den Gegenstand der Erfindung bildende Verfahren soll es ermöglicht werden, aus Sperrholzplatten Körper beliebiger Form, insbesondere solche mit starken doppelten Krümmungen, z. B. Teile von Hüten, auf einfache Weise so herzustellen, daß sie die ihnen durch die Modellkerne gegebene Form genau beibehalten.By the method forming the subject of the invention it is intended be made possible from plywood bodies of any shape, especially those with strong double curvatures, e.g. B. Parts of hats, easy to manufacture, that they exactly retain the shape given to them by the model cores.

Zu diesem Zweck werden die Sperrholzplatten in aufgeweichtem zustand auf den Modellkern gelegt und durch ein heißes, frei von Hand geführtes Bügeleisen durch Bügeln Streifen neben Streifen um den Modellkern herumgebügelt. Hierbei nimmt das Werkstück genau die Form des Modellkernes an und behält diese dauernd bei, weil die gebügelten Teile des Werkstückes durch die Hitze des Bügeleisens an der betreffenden Stelle sofort austrocknen.For this purpose, the plywood panels are in a softened state placed on the model core and through a hot, free hand-operated iron ironed strips next to strips around the model core by ironing. Here takes the workpiece adapts exactly to the shape of the model core and maintains this permanently because the ironed parts of the workpiece by the heat of the iron on the relevant Dry out the area immediately.
