Description

Strangpressenmundstück zur Herstellung feingeaderter Stränge aus plastischen Massen. Die Erfindung betrifft ein in seiner' technischen Gestaltung einfaches, dabei zweckmäßig und zuverlässig wirksames Strangpressemundstück, das zur Herstellung sehr feingeaderter Stränge aus plastischen Massen dient. Die Erfindung besteht darin, daß im Innern eines kegelförmigen,, mit einem zylindrischen Ansatz versehenen Mundstückes ein kegeliger Hohldorn angeordnet ist. Dieser Hohldorn ist in beliebiger Zahl mit radial gerichteten Düsen versehen, die das der Aderung dienende Material unmittelbar in den an ihnen vorbeistreichenden Grundstrang hineinpressen.Extrusion die for the production of finely veined strands from plastic Crowds. The invention relates to a simple in its' technical design, at the same time expediently and reliably effective extrusion nozzle, which is used for production very finely veined strands of plastic masses. The invention consists in that inside a conical, with a cylindrical neck provided mouthpiece a conical hollow mandrel is arranged. This hollow mandrel is available in any number provided radially directed nozzles, which serve the veining material directly press into the base strand that passes them.

Zur näheren Erläuterung des Erfindungsgedankens ist ein Ausführungsbeispiel auf der Zeicl.nung dargestellt, und zwar zeigt Abb. i einen achsialen Längsschnitt und Abb. a einen Schnitt nach A-A der Abli. i. Das Mundstück ist doppelwandig, die äußere Kegelwandung ist mit a bezeichnet, sie mündet in einen zylindrischen Ansatz b aus. Die Innenwandung stellt- einen kegeligen Hohldorn c dar,- der- mit radialen Düsen; d versehen ist, die zweckmäßig spiralförmig in der Innenwandung- C zusammengestellt sind. Das Grundmaterial wird dem von. den beiden Wandungen c und a gebildeten Hohlraum in Richtung des Pfeiles x zugeführt, gleichzeitig wird das der Aderung dienende Material in. den Hohldorn -c und von hier aus durch die Düsen d in das von ihnen vor..-beistreichende Grundmaterial eingepreßt. Der die Austrittsöffnung verlassende Materialstrang zeigt dann eine Aderung, deren Feinheit abhängig ist von der Zahl der Austrittsöffnungen d. Bei sehr feinen Maserungen wird mit dem neuen Mundstück so gearbeitet, daß einmal dunkleres Material mit hellen Streifen, das zweite Mal helleres Material mit dunklen Streifen aus dem Mundstück herausgepreßt und die Stränge dann in dünne Felle geformt und in Streifen abwechselnd nebeneinander in Blockpressen gestellt werden. Beim Schneiden ergibt sich dann eine feine unterbrochene Aderung, welche der Aderung des natürlichen Elfenbeins täuschend ähnlich sieht.For a more detailed explanation of the concept of the invention, an embodiment is shown on the drawing, namely Fig. I shows an axial longitudinal section and Fig. A shows a section according to AA of the Abli. i. The mouthpiece is double-walled, the outer cone wall is denoted by a, it opens into a cylindrical extension b. The inner wall represents - a conical hollow mandrel c - the - with radial nozzles; d is provided, which are expediently put together in the form of a spiral in the inner wall C. The basic material is that of. the two walls c and a cavity formed in the direction of arrow x, at the same time the material used for veining is pressed into the hollow mandrel -c and from here through the nozzle d into the base material brushed by them. The strand of material leaving the outlet opening then shows a vein, the fineness of which depends on the number of outlet openings d. In the case of very fine grains, the new mouthpiece is used in such a way that once darker material with light stripes, the second time lighter material with dark stripes, is pressed out of the mouthpiece and the strands are then formed into thin skins and placed in strips alternately next to each other in block presses. When cutting, the result is a fine, interrupted vein, which looks deceptively similar to the veining of natural ivory.
