Zur Herstellung von Puppen, Tierfiguren, Atrappen usw. wird vielfach Pappe oder ein ähnlicher nachgiebiger Stoff benutzt, aus welchem je nach Bedarf einzelne Teile in einer entsprechenden, aus Ober- und Unterteil bestehenden Form durch Prägen oder Pressen gebildet und dann zu dem Hohlkörper zusammengesetzt und miteinander verbunden werden.For the production of dolls, animal figures, dummies, etc., cardboard or a similar flexible material is used, from which individual parts can be made into a corresponding shape consisting of upper and lower part by embossing or Presses formed and then assembled into the hollow body and connected to one another will.
ίο Das war aber bisher nur möglich, wenn keine von außen nach innen eindringenden Einbuchtungen oder Hohlräume an dem Körper angebracht werden mußten von einer solchen Tiefe, Gestalt oder Lage, daß die Projektion ihrer äußeren Begrenzungspunkte gegen die der inneren hervortrat, was man allgemein mit »unterschnitten« zu bezeichnen pflegt. ,ίο Up to now this was only possible if no penetration from the outside to the inside Indentations or cavities had to be made on the body by one such depth, shape or position that the projection of its outer limit points against that of the inner emerged, what is generally referred to as "undercut" maintains. ,
Wenn dieser Fall vorliegt, muß die Pressung in zwei getrennten Arbeitsgängen und mit doppelten, verschiedenen Werkzeugen vorgenommen werden, derart, daß man zunächst die Hohlkörper ohne Einbuchtungen herstellt oder mit Einbuchtungen von einer solchen Tiefe, daß sie noch nicht unterschnitten sind und an dem so vorbereiteten Arbeitsstück dann im zweiten Gang und außerhalb der zuerst verwendeten Form die Hohlräume mit besonderen Werkzeugen auf die gewünschte Tiefe brachte.If this is the case, the pressing must be carried out in two separate operations and with double, different tools are made, so that one first the hollow body produces without indentations or with indentations of such Depth so that they are not yet undercut and on the work piece that has been prepared in this way then in the second course and outside of the mold used first, the cavities with brought special tools to the desired depth.
Das ist eine umständliche und schwierige Arbeit, da der gepreßte und dadurch in Spannung versetzte Stoff der nachträglichen Erzeugung von Einbuchtungen einen erheblichen Widerstand entgegensetzt und bei der zur Überwindung desselben anzuwendenden Gewalt häufig zerreißt.This is a cumbersome and difficult job because the pressed and thereby in The subsequent creation of indentations put a considerable strain on fabric Opposes resistance and often tears apart when it comes to the force to be used to overcome it.
Nach dem neuen Verfahren wird die Pressung fertiger Hohlkörper mit beliebig tiefen, von außen nach innen eindringenden Hohlräumen in einem Arbeitsgang ausgeführt, derart, daß, während die Form sich schließt und das zwischen den Formteilen befindliche schmiegsame und dehnbare feuchte Blatt noch nicht festgepreßt und deshalb noch nachgiebig ist, besondere Preßstücke an die Form herantreten und das Arbeitsstück ziehend und dehnend in demselben Augenblick in die Einbuchtungen hineinpressen, in welchem der Hohlkörper selbst seine äußere Gestalt erhält.According to the new process, the pressing of finished hollow bodies with any deep cavities penetrating from the outside to the inside carried out in one operation, such that as the mold closes and that between the mold parts pliable and stretchable moist sheet is not yet firmly pressed and is therefore still pliable, special pressed pieces to the Approach the shape and pull and stretch the work piece in the same instant Press into the indentations in which the hollow body itself has its outer Takes shape.
In den Zeichnungen ist die dazu verwendete Vorrichtung in Fig. 1 in einem Längsschnitt, in Fig. 2 in einem Querschnitt nach der Linie A-B dargestellt.In the drawings, the device used for this is shown in Fig. 1 in a longitudinal section, in Fig. 2 in a cross section along the line AB .
In dem festen Unterteil α ist die beliebig gestaltete Form ausgearbeitet, während die auf- und abgehende Oberform b das Gegenstück dazu trägt. Zwischen beiden wird durch Druck das Arbeitsstück χ gebildet.In the fixed lower part α any shape is worked out, while the rising and falling upper shape b carries the counterpart. The work piece χ is formed between the two by pressure.
Um nun an einem solchen gleichzeitig nach innen dringende hohle Einbuchtungen etwa wie h einzupressen, was an sich und nach dem bisher üblichen Verfahren und mit den dazu verwendeten Werkzeugen nicht möglich wäre, ist in einer seitlichen Aus-In order to now press in hollow indentations, such as h , which at the same time penetrate inwards, which in itself and according to the previously usual method and with the tools used for this, would not be possible, a lateral design
