Description
Verfahren zum Überziehen von Körpern aus Metallgewebe mit Kautschuk Es ist bekannt, im Tauchverfahren Körper aus Metallgewebe mit einem Überzug aus Kautschuk o. dgl. Stoffen unter Verwendung einer wäßrigen Dispersion dieser Stoffe herzustellen. Dieses Verfahren bietet jedoch vor allem bei Körpern von verwickelter Form oder großen Abmessungen erhebliche Schwierigkeiten, da zur Durchführung des Tauchvorganges erhebliche Mengen der meist nur kurze Zeit haltbaren Tauchfiüssigkeit bereitgestellt und zur Erzielung einwandfreier Überzüge unbedingt frei von Luftbläschen und festen Teilen, wie Koagulat o. dgl. gehalten werden müssen. Die letztere Bedingung läßt sich im technischen Betrieb bei großen und verwickelten Formen, die ein wiederholtes Tauchen erfordern, nicht durchführen. AuSerdem lassen sich auf diese Weise nur Überzüge von allseitig gleicher Stärke herstellen.Process for covering bodies made of metal mesh with rubber It is known, in the immersion process, to consist of a metal mesh body with a coating Rubber or the like. Substances using an aqueous dispersion of these substances to manufacture. However, this procedure is especially useful for bodies of tangled bodies Shape or large dimensions considerable difficulties, since to carry out the The immersion process involves considerable amounts of the immersion liquid, which usually only lasts for a short time provided and absolutely free of air bubbles to achieve perfect coatings and solid parts, such as coagulum or the like. Must be kept. The latter condition can be used in technical operations with large and intricate shapes that require repeated Require diving, do not perform. In addition, only coatings can be used in this way of the same thickness on all sides.
Bei weitmaschigen Metallgeweben führt außerdem das zum Schließen der Zwischenräume erforderliche mehrfache Tauchen zu einer unenvünschten Stärke des Überzuges.In the case of wide-meshed metal fabrics, this also leads to the closing of the Gaps required multiple dips to an undesirable strength of the Coating.
Auch die Herstellung dieser Körper aus fertig überzogenem Metallgewebe, das durch Aufwalzen oder Aufvulkanisieren von Folien am Stück gefertigt ist, ist unwirtschaftlich, da beim Zuschnitt der Körper ein Teil als unverwendbarer Ab£all zurückbleibt.. Auch ergeben sich erhebliche Schwierigkeiten hilnsichtlich der Verbindung der Stoßstellen sowohl in bezug auf das Metallgewebe als auch auf die Überzugsschichten. Nach den bekannten Einwalzverfahren lassen sich aber nur ebene oder allenfalls gewölbte Platten, aber keine Formkörper herstellen. The manufacture of these bodies from pre-coated metal mesh, which is manufactured by rolling or vulcanizing foils in one piece uneconomical, since when cutting the body a part as unusable waste remains .. There are also considerable difficulties with regard to the connection of the joints with respect to both the metal mesh and the coating layers. According to the known rolling-in process, however, only planar or at most curved Produce plates, but not moldings.
Gemäß vorliegender Erfidnung erfolgt das Überziehen von räumlichen Körpern aus Metallgewebe mit Kautschuk o. dgl. Stoffen, indem zunächst auf eine SeiteZdes Metallgewebekörpers eine Folie aus unvulkanisiertem, plastisch verformbarem Material unter leichtem An drücken aufgelegt bzw. aufgewickelt, worauf durch Aufstreichen oder Aufspritzen einer Lösung oder wäßrigen Dispersion des Überzugsstoffes auf die andere Seite die allseitige Umhüllung in der gewünschten Stärke fertiggestellt wird. According to the present invention, the covering takes place from spatial Bodies made of metal mesh with rubber or the like. Substances by first on a Side of the metal mesh body is a film made of unvulcanized, plastically deformable material Material placed or rolled up with slight pressure, followed by brushing on or spraying a solution or aqueous dispersion of the coating material onto the the other side the all-round covering is completed in the desired thickness.
Durch das neue Verfahren werden auch bei weitmaschigem Gewebe durch eine verhältnismäßig dünne Bezugsschicht in einem Arbeitsgang alle Zwischenräume geschlossen, und man hat es in der Hand, durch einen zweiten Arbeitsgang die Stärke des Überzuges auf beiden Seiten des Gewebes unterschiedlich zu halten. Um eine einwandfreie Verbindung zwischen der Folie und dem nachträglich aufgetragenen Überzugsstoff zu erreichen, werden zweckmäßig dünne Felle aus unvulkanisiertem, noch plastischem Bezugsstoff benutzt, die sich ohne Spannung der Form des Metallgewebekörpers anpassen und beim Vulkanisieren mit dem in Form einer Lösung oder Dispersion aufgebrachten Bezugsstoff eine homogene Schicht bilden. The new process also allows for wide-meshed fabrics a comparatively thin cover layer covers all the gaps in one operation closed, and you have it in your hand, strength through a second step to keep the coating different on both sides of the fabric. To a flawless Connection between the film and the subsequently applied coating material reach, are useful thin skins made of unvulcanized, yet plastic cover fabric is used, which changes the shape of the metal fabric body without tension adapt and when vulcanizing with the applied in the form of a solution or dispersion Form a homogeneous layer of upholstery fabric.
Das neue Verfahren ergibt somit den Vorteil, daß der betreffende Formkörper ohne Mühe aus dem blanken Metallgeflecht hergestellt und dann ohne Vergeudung von Bezugsstoff beiderseits mit einer beliebig starken Schicht überzogen werden kann, wobei das einseitige Aufspritzen gleichzeitig zu einem Schließen der Stoß- oder Überlappungsfugen des Belages führt. The new method thus gives the advantage that the relevant Molded body produced from the bare metal mesh without any effort and then without waste of upholstery fabric covered on both sides with a layer of any thickness can, with the one-sided spraying at the same time to a closing of the butt or overlap joints of the covering.
