Description

Umhüllungen aus Zelluloid wurden bisher unter Erwärmen des Zelluloids mit Hilfe von Formen unter Druck angefertigt. Dabei wurde Wert darauf gelegt, den Zelluloidüberzug möglichst glatt ohne Blasen- oder' Faltenbildung herzustellen: ...Celluloid wrappings were previously made by heating the celluloid with the aid of Molds made under pressure. Great importance was attached to the celluloid coating to be produced as smoothly as possible without the formation of bubbles or wrinkles: ...

Das Verfahren nach der Erfindung ist im Gegensatz dazu zur Herstellung von mannigfachen, gemusterten Gegenständen aus Zelluloid, Nitrozellulose und ähnlichen Stoffen bestimmt, bei denen durch künstliche Bildung λ on Falten, Überlappungen sowie kleinen Bläschen eine rauhe Oberfläche geschaffen, die Festigkeit des betreffenden Gegenstandes erhöht und ein künstlerisches Aussehen erreicht wird.The method according to the invention is in contrast to the production of manifold, patterned objects made of celluloid, Nitrocellulose and similar substances determined in those by artificial formation λ created a rough surface on folds, overlaps and small bubbles, increases the strength of the object in question and achieves an artistic appearance will.

Nach der Erfindung werden diese Gegenstände dadurch hergestellt, daß man Tafeln oder Streifen aus Zelluloid oder dergleichen so in einem Lösungsbade kurze Zeit erweicht, unter Bildung von Überlappungen und Falten in kaltem Zustande mit oder ohne Kern teilweise aufeinander- und aneinanderlegt und das Ganze erhärten läßt.According to the invention, these objects are made by making panels or strips of celluloid or the like so softened in a solution bath for a short time, partially with the formation of overlaps and folds in the cold state with or without a core one on top of the other and next to each other and let the whole harden.

Die Erfindung ist in der Zeichnung veranschaulicht, und zwar zeigt:The invention is illustrated in the drawing, namely shows:

Anivlacetat erwiesen. Die Zelluloidtafel darf nur kurze Zeit in diesem Bade verweilen und ist sodann derart erweicht, daß sie von Hand um einen beliebigen Körper, z. JB. eine Vase 1, umgelegt werden kann. Dieses Umlegen geschieht dabei ι in der Weise, daß in dem Material der Tafel eine größere Anzahl von Faltungen 2 entstehen und ferner möglichst zahlreiche Überlappun-„ £^ei13 erzeugt werden. Die Zelluloidtafeln 5· eier -streifen werden zu diesem Zweck auf dem den Grundkörper- bildenden Gegenstand mit der Hand ausgestrichen, bis ein Körper ungefähr mit einer Faltenbildung, ähnlich der - in Abb. 1 dargestellten Vase, entsteht." Diese Faltenbildung hat den ganz besonderen Zweck, die Festigkeit des Grundkörpers zu erhöhen, indem sie erstens eine Verstärkung der Gesamtumhüllung bilden, zweitens aber auch infolge ihres Vorstehens über die allgemeine Außenfläche der Umhüllung eine gewisse Elastizität der Umhüllung hervorrufen. Dadurch wird der Grundkörper gegen Beschädigung, durch Stoß, Fall o. dgl. gesichert, was besonders bei einem Grundkörper aus einer leicht zerbrechlichen Masse, z. B. Gips, Ton. Porzellan, Steingut, Glas u. dgl., von größter Wichtigkeit ist.Anivlacetate proved. The celluloid board may only stay in this bath for a short time and is then softened so that it can be wrapped by hand around any body, e.g. JB. a vase 1, can be turned over. This folding is done while ι in such a manner that in the material of the panel comprises a greater number of folds 2 arise and numerous further possible Überlappun- "£ generated ^ei1. 3 For this purpose, the celluloid panels 5 egg strips are spread out by hand on the object forming the base body until a body with roughly a fold formation, similar to the vase shown in Fig. 1. "This fold formation has a very special one The purpose is to increase the strength of the base body by firstly forming a reinforcement of the overall envelope, but secondly by creating a certain elasticity of the envelope as a result of their protrusion over the general outer surface of the envelope. This is particularly important in the case of a base body made of an easily fragile mass, e.g. plaster of paris, clay, porcelain, earthenware, glass and the like.

Das Verfahren ermöglicht infolgedessen, z. B. verhältnismäßig leicht zerbrechliche und dünnwandige Hohlkörper durch diese L^Tmhüllung bruchsicher und dauerhaft zu machen, λ\ό1ηη gleichzeitig der Grundkörper aus beliebigen Stoffen hergestellt oder Ausschußmaterial dazu verwendet werden kann, weil 7 die Umhüllung gerade durch die Faltenbildung ein künstlerisches Aussehen erhält, welches durch die Anwendung beliebiger Farben, welche sich leicht in bekannter Weise, auf und in die Zelluloidmasse einbringen'8 lassen, noch erhöht wird.As a result, the method enables e.g. B. to make relatively easily fragile and thin-walled hollow bodies ^{break-proof and durable by this L T} mhüllung, λ \ ό1ηη at the same time the base body made of any materials or scrap material can be used, because 7 the wrinkle is given an artistic appearance, which through the use of any color, which can easily be incorporated into and onto the celluloid mass in a known manner, is further increased.

Durch die Faltenbildung wird ferner dieThe formation of wrinkles is also the

Claims

The outer surface of the body is artificially rough made, which makes it easier to hold the object. This property is. particularly with some everyday objects, such as S the ski ring handle shown in Fig. 2. advantageous, especially but also important z. B. in the steering wheel of motor vehicles, handles on cords and the like.

With the umbrella handle shown in Fig. 2

ίο the base body can consist of any particularly cheap material. While / .. B. otherwise only good, knot-free wood can be used for umbrella handles, it is possible here to use wood with cracks, knots and the like, because it is given such strength by the envelope that the The nature of the material only plays a minor role.

Tn Fig. 2 can be seen. that here a relatively narrow strip 4 of celluloid is wrapped around the base body in a manner known per se by being folded over several times, in such a way that both overlaps 5 and folds 6 arise.

As Figure 3 shows, these overlaps and folds can be used artistically, by the edges 7 of the overlaps according to any motif,. z. B. after the one Rosebud, to be laid.

The sheath allows insertion even if the base body is bad or brittle other parts in a base body, such as. B. in the subject of Fig. 2 one Screw 8, which is used to connect to the

Umbrella pole - serves. It can also be a proportionate one powerful umbrella pole even under disproportionate weakening of the Base body can be used in this because it is the base body through the envelope which is given special strength. .

With a further training of the \ ^; be experienced in the. Coating also creates special warps and bubbles, which improve the artistic impression of the surface, at the same time create further elevations of the envelope surface and thereby increase the protection of the base body against damage by impact. For this purpose, the celluloid board or the celluloid strip is immediately after leaving the solution bath on a smooth surface, e.g. B. a zinc plate, placed and left on this short time.

Under the influence of the still that Strips of adhering droplets of the solution bath captures the entire mass of the strip to work on: there are peculiarly patterned raised warps 9. which are surrounded by a large number of small bubbles 10. This creates a pattern the area achieved, which is particularly characteristic when the Celluloid massc colors are mixed in. By holding the Celluloid strips on the plate as well as by choosing a stronger or weaker one Solution bath you have it in your hand, this one Change pattern.

The process is suitable for the manufacture of a myriad of celluloid articles Covering any basic body, such as cardboard, fiber, as well as for production transparent objects by coating glass according to the method, being straight through the folds, warps and bubbles special lighting effects are achieved.

The celluloid strip can also in a manner known per se around a merely as a shape «■ Haying body turned down or directly shaped by hand without one are, in turn, the overlaps, folds and bubbles as well as warps eggs now only consisting of celluloid objects after being pulled from the " Give shape the necessary strength, even if a relatively thin celluloid strip is used for this.

Follow the procedure described z. B. any kind of hat decorations, artificial flowers and the like great resistance to damage offer the advantage that they are against Xasse and Are not sensitive to moisture.
