Abstract

Bei einem Mundstück (1) zur Herstellung von mit Hoh­ lräumen versehenen Formlingen, das aus einer an der Strangpresse zu befestigenden Vorsetzplatte (2), einem Mundstückrahmen (3) und einer Vielzahl auf Kernhaltern (4) angeordneten Kernen (5) besteht, ist die Vorsetzplatte (2) mit diese durchgreifende Stege (12, 13), vorzugsweise mit parallel zu deren Randteilen verlaufenden Längsstegen (12) und Querstegen (13), versehen, an denen die die Kerne (5) tragenden Kernhalter (4) unmittelbar befestigt sind. In a mouthpiece (1) for the production of Hoh lined moldings, which from a on the Extrusion plate to be attached (2), one Mouthpiece frame (3) and a variety on core holders (4) arranged cores (5), the front plate (2) with this through webs (12, 13), preferably with longitudinal webs (12) running parallel to their edge parts and transverse webs (13), on which the cores (5) supporting core holder (4) are directly attached.

Durch diese Ausgestaltung des Mundstückes (1) wird der Fluß des Tonstranges vergleichmäßigt, ohne daß Stauungen auftreten, auch ist das Mundstück (1) weitgehend maschinell herzustellen. Ferner wird eine Unterteilung des Tonstranges, bevor dieser in das Mundstück (1) eintritt, vermieden, so daß dadurch bedingte Riße beim Brennen weitgehend ausge­ schlossen und homogene Formlinge zu pressen sind. With this design of the mouthpiece (1) Flow of the clay strand is evened out without congestion occur, the mouthpiece (1) is largely mechanical to manufacture. Furthermore, a subdivision of the clay string, before this enters the mouthpiece (1) avoided so that this largely caused cracks when burning closed and homogeneous moldings are to be pressed.
