Description

Die Erfindung betrifft ein Speisermodeil mit eiaem Kern und einpjn Mantel nach Patent 28 03 247, wobei der Kern entfeiTtbar ist, um so den eigentlichen Speiser zu bilden.The invention relates to a feeder model with a core and a jacket according to patent 28 03 247, wherein the core can be separated in order to form the actual feeder.

Während noch das Speisermodell nach der Hauptanmeldung auf eine Kugelform oder im wesentlichen eine Kugelform abhebt, haben Versuche ergeben, daß merkliehe Abweichungen von einer idealen Kugelform, die zwar auch bereits einen etwa xegelstumpfförmigen Fußabschnitt und in diesem eine Einschnürung aufweist, möglich sind und unter Umständen von Vorteil sind.While still the riser model after the main registration on a spherical shape or essentially a spherical shape, experiments have shown that Merkliehe Deviations from an ideal spherical shape, which is already roughly a truncated cone Foot portion and in this has a constriction, are possible and may be advantageous.

Es wird daher in erfindungsgemäßer Weiterausgestaltung eines Speisennodelles mit einem Kern und einem Mantel nach Patent 28 03 247 gemäß Oberbegriff des Patentanspruchs vorgeschiagen, d-Jß das Speisermodell einen vergasbaren Schaumuoffabschnitt mit U-förmigem Längsschnitt in einem auße . zylinderförmigen Mantel aus wärmeisolierender oder exothermer Masse aufweist. Auch innerhalb dieser Gestaltung besitzt das Speisermodell, mindestens jedoch sein Kern mit Vorteil eine durch großen Rauminhalt bei kleiner Oberfläche bestimmte Form. Durch diese Maßnahmen werden denkbar die Herstellungs- wie die Einsatzmöglichkeiten eines solchen Speisermodells erweitert.It is therefore proposed in a further development according to the invention of a food model with a core and a jacket according to patent 28 03 247 according to the preamble of the patent claim, that is, the food model has a gasifiable foam section with a U-shaped longitudinal section in an exterior. having a cylindrical jacket made of heat-insulating or exothermic mass. Even within this design, the feeder model, but at least its core advantageously, has a shape determined by the large volume with a small surface area. By means of these measures, the manufacturing and application possibilities of such a feeder model are conceivably expanded.

in der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt, und zwar ein Speisermodell mit einem etwa tulpenförmigen Kern 1 und darüber einem außen etwa zylindrischen Mantel 2, in den bei einstückiger Ausbildung ein Luftdruckkern 21 eingeformt ist, dies bei gegenüber einer Modellplatte m hinterschnittener Ausbildung. In the drawing, an exemplary embodiment is shown schematically, namely a feeder model with an approximately tulip-shaped core 1 and above it an externally approximately cylindrical jacket 2, in which an air pressure core 21 is molded in the case of a one-piece design, this with an undercut design compared to a model plate m.
