Die Neuerung bezieht sich auf Vorrichtungen zum Herstellen von ProfilstrSngen aus elastomeren Werkstoffen mit teilstreckenweise an ihre gekrümmten Außenkonturen angesetzten DichtHppen, mit einer Strangpresse und einem vor dem Pressen-Mundstöck quer zur Längsrichtung der Profil stränge bis an deren Außenkontur heran bewegbaren Schneidmesser. The innovation relates to devices for producing profile strings made of elastomeric materials with partial stretches of their SealingHppen attached to curved outer contours, with an extrusion press and one in front of the press mouthpiece transversely to the longitudinal direction of the Profile strands up to their outer contour movable cutting knife.
Es ist allgemein QbIich, die beispielsweise zum Einfassen von Fenster· scheiben an Fahrzeugen und Gebäuden verwendeten Profilstränge in praktisch unbegrenzten Längen nach dem Strangpreß-Verfahren durch Auspressen der im vorwiegend plastischen Zustand befindlichen eiastcmeren Werkstoffmischung aus einem zweckentsprechend gestalteten Mundstück herzustellen. Eine besondere Problematik erwächst dabei aus der verschiedentlich erhobenen Forderung, die einheitlich mit angeformten Dichtlippen teilstreckenweise auszusparen. Das nachträgliche mechanische Beschneiden der fertig hergestellten Profilstränge ist zeitaufwendig und unwirtschaftlich und hat zudem den Nachteil, daß nichtverwendbarer vernetzter Elastomer-Werkstoff anfällt. Es ist bekannt (deutsche Patentschrift 1 179 358), stranggepreßte Profilleisten unmittelbar nach ihrem Austreten aus dem Pressen-Mundstück durch ein kraftbetätigtes Schneidwerkzeug nach einem vorgegebenen Muster abschnittsweise auszuschneiden. Die bekannte Vorrichtung 1st aber ohne Rücksicht auf die Querschnittsform derIt is generally used, for example, for framing windows. disks profile strands used on vehicles and buildings in practically unlimited lengths according to the extrusion process Squeezing out the eggs, which are predominantly in a plastic state Mixture of materials from an appropriately designed Manufacture mouthpiece. A special problem arises from the various demands made, which are uniform with partially cut out molded sealing lips. The subsequent mechanical trimming of the finished profile strands is time-consuming and uneconomical and also has the Disadvantage that unusable crosslinked elastomer material is obtained. It is known (German Patent 1,179,358), extruded Profile strips immediately after they emerge from the press mouthpiece cut out in sections using a power-operated cutting tool according to a predetermined pattern. The well-known Device is regardless of the cross-sectional shape of the

Der Neuerung liegt als Aufgabe eine neuartige Gestaltung von Vorrichtungen zugrunde mit dem Ziel, die Herstellung von für Einfaß- und Dichtungszwecke verwendbaren Profil strängen mit wechselweise einheitlich angeformten bzw. ausgesparten Dichtlippen unter Verwendung von Strangpressen zu ermöglichen und dabei die übergänge zwischen den verschiedenen Abschnitten in genauer Entsprechung zu den bogenförmig gekrümmten Außenkonturen der Stränge zu gestalten. Diese Aufgabe wird, ausgehend von Vorrichtungen der eingangs geschilderten Art, erfindungsgemäß dadurch gelöst, daß das über den Quer-The task of the innovation is a novel design of devices with the aim of the production of usable for edging and sealing purposes profile strands with alternately To enable uniformly molded or recessed sealing lips using extrusion presses and thereby the transitions between to shape the various sections in exact correspondence to the arcuate outer contours of the strands. These The object is, based on devices of the type described above, achieved according to the invention in that the transverse

In a further embodiment of the invention, the cutting blade may be formed by a corresponding i & itself in r outer contour of the profile strands bent high-strength sheet metal strip.
