Description

Kamm aus Acetylcellulose in Havanna-Maserung Die aus Celluloid bestehenden Kämme wurden durchweg in einer bereits im Ausgangsmaterial vorhandenen Havanna- oder Cubana-Maserung auf den Markt gebracht, so daß sich die Verbraucherkreise an diese Maserung gewöhnt haben und diese Artikel in dieser Maserung stark bevorzugen.Acetyl cellulose comb with Havana grain Those made of celluloid Combs were consistently made in a Havana version that was already present in the starting material. or Cubana grain brought to market, so that the consumer circles to have got used to this grain and strongly prefer these items in this grain.

Seit mehr als 20 Jahren werden auch Kämme aus Acetylcellulose im Spritzgußverfahren hergestellt, jedoch war es bisher nicht möglich, diesen Gegenständen die bevorzugte Havanna-Maserung zu geben, obwohl man viele Versuche zu diesem Ziel unternommen hat, die jedoch alle nicht geglückt sind. So hat man sich bisher damit beholfen, daß man entsprechend gefärbte Ausgangsprodukte mischte und diese zu den Gegenständen spritzte. Da jedoch bei der hohen Temperatur(I500 und mehr), die beim Spritzgußverfahren vorkommen, die Farben ineinanderfließen, kommt immer nur ein Produkt heraus, das man in der Fachwelt als Schildpatt zu bezeichnen pflegt, nicht aber die gewünschte Havanna- oder Cuhana-Maserung der Celluloidkämme. An diesem Zustand krankte bisher die Einführung der Kämme aus Acetylcellulose, obwohl diese sonst gegenüber den Celluloidkämmen wesentliche Vorteile haben, wie insbesondere die größere Billigkeit, größere Haltbarkeit, Nichtfeuergefährlichkeit und volkswirtschaftliche Bedeutsamkeit, da diese Kunststoffspritzgußmassen ganz aus heimischen Rohstoffen bestehen. For more than 20 years, combs made from acetyl cellulose have also been used in the Injection molding produced, however, it was previously not possible to produce these items to give the preferred Havana grain, although many attempts have been made towards this goal has undertaken, but none of them have succeeded. That’s how it’s been done so far make sure that you mix appropriately colored starting materials and add them to the Objects splashed. However, since at the high temperature (I500 and more) that at Injection molding processes occur, the colors flow into each other, only comes one Product that experts call tortoiseshell, not but the desired Havana or Cuhana grain of the celluloid combs. At this State so far sick the introduction of the combs made of acetyl cellulose, although this otherwise have significant advantages over celluloid combs, such as in particular greater cheapness, greater durability, non-flammability and economic Significance because these plastic injection molding compounds are made entirely from local raw materials exist.

Dieses Problem hat in der vorliegenden Erfindung eine Lösung gefunden. Die Erfindung besteht in einem Kamm aus Acetylcellulose, der dadurch gekennzeichnet ist, daß auf den in Blond gespritzten Kamm mittels Schablone und Farblack in an sich bekannter Weise die Havanna-Maserung aufgespritzt ist. Bei der Musterung der Kämme ist darauf zu achten, daß die Schablone auf beiden Seiten immer dieselben Stellen bedeckt, damit sich die Aufspritzungen mit den hellen Stellen nicht überschneiden. This problem has been solved in the present invention. The invention consists in a comb made of acetyl cellulose, which is characterized is that on the comb sprayed in blonde using a stencil and colored varnish in on themselves As is known, the Havana grain is sprayed on. at When patterning the combs, make sure that the stencil is on both sides always covers the same areas so that the injections can be combined with the light areas do not overlap.

Die aus Acetylcellulose bestehenden und im Spritzguß verfahren hergestellten Kämme sind also auf einfache und billige Weise mit einer naturgetreuen Havanna- oder Cubana-Maserung versehen, so daß sie nunmehr in der billigen Kunststoffspritzgußausführung weitesten Bevölkerungskreisen zugänglich gemacht werden können. Hinzu kommt noch ein wesientlicher volkswirtschafilicher Vorteil, der darin besteht, daß gewisse Bestandteile des Celluloids, die bisher von auswärts eingeführt werden müssen, bei der Kunsts toffspritzgußmasse nicht erforderlich sind, die ausschließlich aus heimischen Rohstoffen besteht. The existing acetyl cellulose and manufactured by injection molding Combs can therefore be easily and cheaply made with a lifelike Havana or Cubana grain, so that they are now in the cheap plastic injection molding can be made accessible to the broadest sections of the population. Additionally an essential economic advantage, which consists in the fact that certain Components of the celluloid that previously had to be introduced from outside The plastic injection molding compound is not required, which is exclusively from domestic Raw materials.
