In der Fachveröffentlichung "Shibori-The Inventive Art of Japanese Shaped Resist Dying", Kodansha Int., 1983, Seiten 123 - 138, ist ein Verfahren zum Erzeugen von gefärbten Mustern auf einem Stoff offenbart. Bei diesem Verfahren wird der Stoff um einen Stab gewickelt, ein Faden um den Stoff gelegt, der Stoff auf der Stange zusammengeschoben und abschließend in diesem zusammengeschobenen Zustand gefärbt. Durch dieses Verfahren bildet sich auf dem Stoff, der nach dem Färben wieder auseinandergezogen wird, ein Muster, das von der Faltung des Stoffes vor dem Aufbringen auf die Stange, der Wicklungsdichte des Fadens und der Richtung der Windung abhängt.In the specialist publication "Shibori-The Inventive Art of Japanese Shaped Resist Dying ", Kodansha Int., 1983, pages 123-138, is a method of producing colored patterns revealed on a fabric. With this procedure the fabric wrapped around a stick, a thread around the fabric placed, the fabric pushed together on the pole and finally colored in this collapsed state. This process forms on the substance that is drawing apart again, a pattern that from the folding of the fabric before applying it to the bar, the winding density of the thread and the direction of the turn depends.
Zur Herstellung von Lampenschirmen aus Papier ist es notwendig, daß das Papier eine räumliche Struktur annimmt, so daß die daraus gebildeten Lampenschirme diese Struktur nach Abschluß des Verfahrens beibehalten. Dies bedeutet, daß sich die Form der Papierlampenschirme nach deren Herstellung nicht mehr ändert.To manufacture lampshades from paper, it is necessary that the paper takes on a spatial structure, so that the lampshades formed from this structure Maintain completion of the procedure. This means that the shape of the paper lampshades after their manufacture no longer changes.
Die oben beschriebenen Verfahren beschäftigen sich ausschließlich mit der Faltung bzw. Plissierung von Stoffen, wobei es offensichtlich ist, daß durch diese Verfahren keine räumliche Struktur der Stoffe geschaffen wird, wie sie beispielsweise bei Lampenschirmen, die nicht auf ein Tragegitter aufgespannt werden, sondern lediglich durch eine Stützkonstruktion getragen werden, unerläßlich ist.The procedures described above deal exclusively with the folding or pleating of fabrics, it is obvious that none of these methods spatial structure of the fabrics is created, such as for lampshades that are not on a carrycot be spanned, but only by a support structure be worn is essential.
Aus der US-A-1 958 459 ist ein Verfahren zum Herstellen von gefalteten Lampenschirmpapier bekannt, bei dem Pràgerollen verwendet werden.From US-A-1 958 459 is a method for producing folded Known lampshade paper using embossing rolls will.

Das erfindungsgemäße Verfahren zur Herstellung von Papierlampenschirmen wird nun anhand eines Beispiels beschrieben. Die verschiedenen Verfahrensschritte sind in Fig. 1 dargestellt.The method according to the invention for the production of paper lampshades will now be described using an example. The various process steps are shown in Fig. 1.
Figuren 1a und 1b zeigen den ersten Verfahrensschritt, bei
dem ein Papier 100, aus dem der Papierlampenschirm hergestellt
wird, um einen Teil oder um die gesamte Mantelfläche
102 eines Zylinders 104 gewickelt wird. Es ist offensichtlich,
daß das Papier 100 hierbei auch mehrmals um den Zylinder
102 gewickelt werden kann, sofern dies erwünscht ist,
wodurch eine Überlagerung des Papiers bewirkt wird.Figures 1a and 1b show the first process step, at
a
Nachdem das Papier 100 auf den Zylinder 104 aufgebracht ist,
wird im zweiten Verfahrensschritt, der in Fig. 1c gezeigt
ist, ein Faden 106 um das Papier 100 gewickelt. Das Umwickeln
des Papiers 100 mit dem Faden 106 kann zum Beispiel
durch eine Drehung des Zylinders 104 durchgeführt werden,
wie es in Fig. 1c durch den Pfeil angedeutet ist. Diese Drehung
kann entweder durch einen elektrischen Motor oder von
Hand erfolgen.After
Beim dritten Verfahrensschritt, der in Fig. 1d gezeigt ist,
wird das mit dem Faden 106 umwickelte Papier 100 in eine
Richtung entlang des Zylinders 104 zusammengeschoben, wie es
in Fig. 1d durch den Pfeil gezeigt ist. Wenn es erwünscht
ist, kann beim Zusammenschieben zusätzlich ein Verdrehen des
Papiers 100 erfolgen. Durch dieses Zusammenschieben des Papiers
wird dieses gefaltet, so daß es eine räumliche Struktur
annimmt.In the third method step, which is shown in FIG. 1d,
the
Abhängig von der erwünschten räumlichen Struktur, wird der dritte Verfahrensschritt einmal oder mehrmals wiederholt.Depending on the desired spatial structure, the third step repeated one or more times.
Beim letzten Verfahrensschritt, der in Fig. 1 nicht gezeigt
ist, wird das zusammengeschobene Papier 100 von dem Zylinder
104 entfernt.In the last process step, which is not shown in FIG. 1
the
Weist der im letzten Schritt von dem Zylinder 104 abgenommene
Papierlampenschirm noch nicht die endgültige Form auf, so
wird ein weiterer Verfahrensschritt hinzugefügt (nicht gezeigt),
bei dem das zusammengeschobene, gefaltete Papier
nach der Entfernung von dem Zylinder 104 auseinandergezogen
bzw. geglättet wird, so daß der erwünschte Papierlampenschirm
entsteht.Has the one removed from the
Zusätzlich zu den in Fig. 1 dargestellten Verfahrensschritten kann das erfindungsgemäße Verfahren gemäß einem weiteren Ausführungsbeispiel weitere Schritte umfassen.In addition to the process steps shown in FIG. 1 can the inventive method according to a further embodiment include further steps.
Vor dem ersten Verfahrensschritt wird das Papier 100 gewalkt. Before the first process step, the
Abhängig von der erwünschten Form des herzustellenden Lampenschirms kann das Papier nach dem Walken zusätzlich noch gefaltet werden.Depending on the desired shape of the lampshade to be made the paper can also be added after walking be folded.
Nach dem dritten Verfahrenschritt werden die folgenden Schritte durchgeführt:After the third step, the following are Steps taken:
Das gefaltete Papier 100 wird auf dem Zylinder 104 getrocknet.
Dies kann abhängig von der erwünschten Steifigkeit
des sich ergebenden Lampenschirms durch Zuführung von Wärme
erfolgen.The folded
Um die Steifigkeit des Lampenschirms weiter zu verbessern, kann vor dem Trocknen des Papiers dieses gewässert und mit Fixativen behandelt werden. Bekannte Fixative schließen z.B. Wasserdampf oder Wasserglas ein.To further improve the rigidity of the lampshade, can be dried and dried before drying the paper Fixatives are treated. Known fixatives include e.g. Steam or water glass.
Nach dem Trocknen wird der Faden 106 entfernt, so daß sich
das gefaltete Papier 100 von dem Zylinder 104 entfernen
läßt.After drying, the
Abhängig von der erwünschten Form des Lampenschirms kann vor dem Beginn der Herstellung des Lampenschirms eine Vorbehandlung der verwendeten Papiere erfolgen. Diese Vorbehandlung schießt beispielsweise das Verleimen mehrerer Bögen Papier, das Aufleimen von Papiertaschen und das Einschneiden und/oder Stanzen der Papiere ein.Depending on the desired shape of the lampshade you can choose a pretreatment at the beginning of the manufacture of the lampshade of the papers used. This pretreatment For example, if several sheets of paper are glued together, the gluing of paper bags and the cutting and / or punching the papers.
Ebenso kann während der Herstellung des Lampenschirms eine Behandlung erfolgen, während der der Lampenschirm zum Beispiel eingefärbt oder vergoldet wird.Similarly, during the manufacture of the lampshade Treatment is done during the lampshade for example is colored or gilded.
Es ist offensichtlich, daß alle oben beschriebenen Verfahrensschritte zur Herstellung eines Lampenschirms oder einzelne Verfahrensschritte, insbesondere der zweite und dritte Verfahrensschritt, auch mehrmals durchgeführt werden können, um so eine erwünschte Form und Struktur des Lampenschirms herbeizuführen. It is evident that all of the process steps described above to manufacture a lampshade or individual Process steps, especially the second and third Process step that can also be carried out several times the desired shape and structure of the lampshade bring about.
Insbesondere kann bei der Wiederholung der ersten bis vierten Verfahrensschritte die erneute Umwicklung des Papiers um den Zylinder derart erfolgen, daß die neue Ausrichtung des Papiers gegenüber der ursprünglichen Ausrichtung verdreht ist.In particular, when repeating the first to fourth process steps the rewrapping of the paper be done around the cylinder so that the new alignment of the paper versus the original orientation is twisted.
Im Folgenden wird der in Fig. 2 dargestellte besondere Verlauf
des Faltmusters beschrieben. Wie in Fig. 2 dargestellt
ist, weist das Faltmuster, das durch das erfindungsgemäße
Verfahren erzeugt wird, verschiedene Abschnitte auf. Im Gegensatz
zu bekannten Faltverfahren, bei denen sich jeweils
gleiche Faltabschnitte aneinanderreihen, die lediglich in
entgegengesetzte Richtungen ausgerichtet sind, erzeugt das
erfindungsgemäße Verfahren ein Faltmuster, bei dem sich ein
spitzer Abschnitt 200 und ein bogenförmiger Abschnitt 202
abwechselnd aneinanderreihen. Diese Abschnitte 200 und 202
können unterschiedliche Höhen und Radien aufweisen.The special curve shown in FIG. 2 is shown below
of the folded pattern. As shown in Fig. 2
is, the folding pattern, which by the inventive
Process is generated on different sections. In contrast
to known folding processes, each of which
Line up the same folded sections that are only in
are oriented in opposite directions
The inventive method a folding pattern, in which a

Der jeweilige Verlauf des Faltmusters, genauer gesagt die
Abstände der Spitzenabschnitte 200 voneinander, hängt von
der Wickeldichte des Fadens 106 ab. Diese Wickeldichte ist
variabel, so daß auf einem einzelnen Papier unterschiedliche
Abstände zwischen den Spitzenabschnitten 202 des Faltmusters
entstehen können.The respective course of the folding pattern, more precisely that
Spacing of the
Abhängig von der Größe des herzustellenden Lampenschirms
werden verschiedene Zylinder 104 mit unterschiedlichen
Durchmessern verwendet, wobei die verwendeten Zylinder 104
beispielsweise aus Kunststoff oder Metall hergestellt sind.Depending on the size of the lampshade to be made
Zur Anwendung des erfindungsgemäßen Verfahrens ist es nicht
erforderlich, daß das Papier 100 in einer bestimmten Form
oder Dicke vorliegt. Dies bedeutet, daß das verwendete Papier
100 vor dem Aufbringen auf den Zylinder 104 auf eine
vorbestimmte Form zugeschnitten sein kann und/oder in einer
vorbestimmten Form gefaltet sein kann. Die Form des Zuschnitts
und /oder der Faltung hängt von der erwünschten
Form des Lampenschirms ab. Es ist offensichtlich, daß diese
Maßnahmen die Herstellung von Papierlampenschirmen mit komplexeren
Formen ermöglichen.It is not for the application of the method according to the invention
required that the

des erfindungsgemäßen Herstellungsverfahrens ist durch eine
Faltung des Papiers entlang zweier sich gegenüberliegender
Außenkanten des späteren Schirmes bewirkt.The spherical shape of the
Für den Fachmann ist es jedoch offensichtlich, daß sowohl die Gestalt des noch ungefalteten Papiers wie auch die Dichte der erzeugten Falten, die durch den Wicklungsverlauf definiert ist, vom Designer des Lampenschirmes in weiten Grenzen modifizierbar sind.However, it is obvious to the person skilled in the art that both the shape of the still unfolded paper as well as the Density of wrinkles generated by the winding course is broadly defined by the designer of the lampshade Limits can be modified.
