Description

Verfahren zur Herstellung geschweifter Wandungen für Möbel und andere Gegenstände aus dicken Sperrholzplatten. Es ist bekannt, geschweifte Wandungen für Möbel und andere Gegenstände aus verleimten Furnierplatten in der Weise herzustellen, daß solchen Sperrholzplatten durch feuchtes Aufspannen auf Lehren oder Kerne oder Einspannung zwischen gekrümmten Preßplatten und Trocknen in diesem Zustande die gewollte Krümmung aufgedrückt wird. Nun müssen aber die Flächen zur Vorbereitung des schließlichen Polierens (auf der Außenseite) bzw. zur Erzielung eines guten Aussehens (auf der Innenseite, sofern diese nicht auch poliert «-erden soll) grob- und feingeschliffen werden, was bei gekrümmten Flächen in technisch und zugleich wirtschaftlich befriedigender Weise (also auf niaschiiiellem Wege) nicht gut zu erreichen ist. Der Ausweg, die Sperrholzplatten in ebenem Zustande, also vor dem Krümmen, zu schleifen, versagt bei den Wandstärken, die der Bau solider Möbel, Ladeneinrichtungen, Ausstattungen von Schiffsräumen usw. in der Regel verlangt. Ebene Sperrholzplatten von hinreichender Stärke sind so steif, daß sie sich entweder überhaupt nicht oder doch nicht ohne Schaden für die geschliffenen Flächen krümmen lassen. Auch ein anderer Ausweg, nämlich der, die die Außenflächen ergebenden Furnierblätter vor dem Krümmen zu schleifen, ist ungangbar, weil sich die dünnen Blätter nicht gut maschinell schleifen lassen. Erfindungsgemäß werden deshalb geschweifte «'andungen von größerer Stärke in der Weise erzeugt, daß zunächst zwei je aus mehreren Dickten bestehende Sperrholzplatten, «-elche zusammen die gewollte Wandstärke ergeben, in ebenem Zustande hergestellt und einseitig geschliffen, sodann aber mit den nichtgeschliffenen Seiten verleinitund gleichzeitig in der bekannten Weise gekrümmt werden. Hierzu ist zu bemerken, daß die Herstellung dicker Sperrholzplatten aus zwei mehrschichtigen Teilplatten an sich bekannt ist. Am Wesen der Erfindung würde durch die Einfügung einer dritten oder Mittelschicht zwischen die genannten beiden Sperrholzschichten nichts geändert «-erden; eine solche Ausführung wird aber selten in Frage kommen.Process for the production of curved walls for furniture and others Objects made from thick sheets of plywood. It is known to have curly walls Manufacture furniture and other objects from glued veneer panels in such a way that that such plywood panels by damp clamping on gauges or cores or Clamping between curved press plates and drying in this state desired curvature is imposed. But now the areas have to be prepared the final polishing (on the outside) or to achieve a good one Appearance (on the inside, unless it should also be "polished") roughly- and finely honed, what with curved surfaces in technical and at the same time economically satisfactory (i.e. in a niaschiiial way) not well is to achieve. The way out, the plywood sheets in an even state, so before Bending, grinding, fails with the wall thicknesses that the construction of solid furniture, shop fittings, Equipment of ships' rooms etc. is usually required. Flat plywood panels of sufficient strength are so stiff that they either do not or but do not let it bend without damaging the sanded surfaces. Another too The way out, namely that of the veneer sheets forming the outer surfaces before bending sanding is impractical because the thin sheets do not sand well with the machine permit. According to the invention, therefore, curly patches are of greater strength produced in such a way that initially two plywood panels, each consisting of several thicknesses, «-Which together result in the desired wall thickness, manufactured in an even state and sanded on one side, but then finished with the non-sanded sides be curved simultaneously in the known manner. It should be noted that the production of thick plywood panels from two multi-layer sub-panels is known. The essence of the invention would be enhanced by the insertion of a third or middle layer between said two layers of plywood nothing changed "-earth; however, such a design is seldom an option.

Erfindungsgemäß werden also zunächst zwei ebene Sperrholzplatten gefertigt, die zweckmäßig aus je drei Dickten bestehen. Diese Teilplatten sind stark genug, um auf der Schleifmaschine einwandfrei geschliffen werden zu können, und biegsam genug, uni bei ihrer Vereinigung gleichzeitig die gewünschte Krümmung der Gesamtplatte zu gestatten,According to the invention, two flat plywood panels are first made, which suitably consist of three thicknesses each. These sub-panels are strong enough in order to be able to be perfectly sanded on the sanding machine, and flexible enough, uni at the same time the desired curvature of the entire plate when they are united to allow
