PATENT-ANSPRÜCHE : 1. Kern zum Formen hohler Gegenstände aus Materialien, die nach der Formgebung einem Härtungs- oder Vulkanisiertmgsprozess unter innerem und äusserem Drucko unterworfen werden, dadurch gekennzeichnet, dass die bekannte schmiegsame Umhüllung (6) mit einer Füllung von feinkörnigem Material (Sand u. dgl.) versehen ist, auf welches ein Druck ausgeübt werden kann, zum Zwecke, selbst bei geringem Druck einen bedeutenden Widerstand zu erzielen. PATENT CLAIMS: 1. Core for shaping hollow objects made of materials which, after shaping, are subjected to a hardening or vulcanization process under internal and external pressure, characterized in that the well-known pliable covering (6) with a filling of fine-grain material (sand and the like. ) is provided on which a pressure can be applied, for the purpose of obtaining significant resistance even at low pressure. 2. Ausführungsform des Kernes nach Anspruch 1, gekennzeichnet durch einen in das Füllmaterial eindrückbaren Verdränger (h,), der den erforderlichen Innendruck erzeugt und hiedurch den Kern in die richtige Gestalt bringt. 2. Embodiment of the core according to claim 1, characterized by a displacer (h,) which can be pressed into the filler material and which generates the required internal pressure and thereby brings the core into the correct shape. 3. Ausführungsform des Kernes nach den Ansprüchen 1 und 2, mit einem innerhalb der Umhüllung befindlichen Gerippe, dadurch gekennzeichnet, dass das Gerippe (a) die Lagerung für den Verdränger (h) enthält. 3. Embodiment of the core according to claims 1 and 2, with a framework located within the sheath, characterized in that the framework (a) contains the bearing for the displacer (h). 4. Ausführungsform des Kernes nach Anspruch 3 für Gummischuhformen, dadurch gekennzeichnet. dass das Gerippe (a) aus einem allenfalls durchbrochenen Steg besteht, der oben und unten je eine Platte (c bzw. d) zur Befestigung des schmiegsamen Umhüllungsmaterials trägt 4. embodiment of the core according to claim 3 for rubber shoe molds, characterized. that the framework (a) consists of an openwork web, which carries a plate (c or d) at the top and bottom for fastening the pliable covering material
