Description
Verfahren zum Überziehen gewundener Zugfedern mit einem elastischen organischen Bindemittel Die Erfindung betrifft ein Verfahren zum tÇberziehen gewundener Zugfedern mit einem elastischen organischen Bindemittel. Dieser Überzug soll die Feder vor schädlichen äußeren Einflüssen schützen.Method for covering coiled tension springs with an elastic organic binders The invention relates to a method for coating winding Extension springs with an elastic organic binder. This coating is said to be the Protect the spring from harmful external influences.
Bei den bisher bekannten mit einem Überzug versehenen Zugfedern ist die Feder nur an ihrer Außenseite bekleidet, so daß die einzelnen Windungen der Feder nicht allseitig umhüllt sind. Bei diesen Federn kann daher die hülsenförmige Bekleidung leicht beschädigt und von der Feder gelöst werden. Beim Dehnen der Feder zum Spannen derselben, wie es beim Verwenden der Feder als Träger für Gardinen erforderlich ist, wird auch der Überzug beispielsweise bis 10 % oder mehr zusammen mit der Feder gedehnt. Bei Verwendung von Kunststoffen als Überzüge tritt zufolge der Alterung eine größere Porosität ein, und zwar um so schneller je nachdem der Überzug mehr gedehnt ist, so daß das Metall der Feder doch angegriffen wird. In the case of the tension springs previously known with a coating the spring is covered only on its outside, so that the individual turns of the Feather are not covered on all sides. In these springs, therefore, the sleeve-shaped Clothing easily damaged and detached from the spring. When stretching the spring for tensioning the same, as required when using the spring as a support for curtains is, the coating will also, for example, up to 10% or more together with the spring stretched. When using plastics as coatings, aging occurs a greater porosity, and the faster the more the coating is stretched so that the metal of the spring is attacked.
Auch hat man vorgeschlagen, eine Feder aus mit einem Überzug versehenem Draht zu winden. It has also been proposed to use a spring made of coated Coiling wire.
Zweck der Erfindung ist, die genannten tJbelstände einer mit einem Überzug versehenen Zugfeder zu vermeiden. Zu diesem Zweck wird die Feder während des Auftragens des Bindemittels so weit gedehnt, daß die Windungen voneinander frei sind, worauf nach dem Festwerden des Überzugs die Dehnung der Feder aufgehoben wird, so daß dieselbe ihre ursprüngliche Länge wieder zu erreichen versucht. Beim Auftragen des Bindemittels auf die Feder wird das Material zwischen benachbarten Windungen hineindringen und auch die innere Seite der Feder erreichen, so daß die Windungen allseitig umhüllt werden. Dabei kann der von der Feder umschlossene hohlraum ganz mit dem Bindemittel ausgefüllt werden, so daß ein massiver Kern erzielt wird. Falls nun die Windungen nach dem Überziehen der Feder durch Aufheben der Dehnung ihre ursprüngliche gegenseitige Lage vor der Dehnung wieder zu erreichen versuchen, wird das Bindemittel zwischen den Windungen zusammengedrückt und wird das zwischen den Windungen befindliche Material nach außen gedrückt werden, da das an der inneren Seite der Feder vorhandene Bindemittel dem Einwärtsdringen des zwischen den Windungen befindlichen Materials entgegenwirkt, denn das an der inneren Seite der Feder vorhandene Bindemittel wird durch Aufheben der Dehnung auch zusammengedrückt. The purpose of the invention is to provide the abovementioned dust with a To avoid coated tension spring. To this end, the spring is used during the application of the binder stretched so far that the turns free from each other whereupon the stretching of the spring is released after the coating has set, so that it tries to regain its original length. When applying The binder on the spring becomes the material between adjacent turns penetrate in and also reach the inner side of the spring so that the coils be wrapped on all sides. The cavity enclosed by the spring can be completely be filled with the binder, so that a solid core is achieved. If now the coils after pulling the spring over by releasing the stretch will try to reach the original mutual position again before stretching the binder is compressed between the turns and becomes that between the Windings located material are pressed outwards, because that on the inner Side of the spring existing binder to the inward penetration of the between the coils located material counteracts, because the existing on the inner side of the spring Binder is also compressed by releasing the stretch.
Bei der Anwendung der Feder als Träger für Gardinen oder als Spanndraht wird die Feder wieder gedehnt und erhält eine gewisse Spannung, so daß der Druck auf den Überzug aufgehoben wird, da die Feder während des Auftragens des Bindemittels wenigstens ungefähr in gleichem Maße gedehnt war.When using the spring as a support for curtains or as a tension wire the spring is stretched again and receives a certain tension, so that the pressure on the coating is lifted as the spring during the application of the binder was stretched at least about the same amount.
In der Gebrauchslage kann der Überzug der Feder daher praktisch spannungslos sein.In the position of use, the coating of the spring can therefore be practically tension-free be.
Als Bindemittel kann jeder geeignete Kunststoff, z. B. Polyvinylchlorid, dem ein Weichmacher zugesetzt ist, jedoch auch Kautschuk benutzt werden. Any suitable plastic, e.g. B. polyvinyl chloride, to which a plasticizer is added, but rubber can also be used.
Die Erfindung beschränkt sich nicht auf Federn mit schraubenlinienförmigen Windungen, da sämtliche Windungen auch in einer gemeinsamen Ebene liegen können. Der Querschnitt des Drahtes, aus welchem die Feder gewunden ist, braucht nicht rund zu sein, sondern kann jede geeignete Form haben. The invention is not limited to springs with helical shapes Turns, since all turns can also lie in a common plane. The cross-section of the wire from which the spring is wound does not need to be round to be, but can be of any suitable shape.
