Verfahren zur Herstellung von vulkanisierten Gegenständen Process for the manufacture of vulcanized articles

Die Erfindung betrifft ein Verfahren zum Verarbeiten von unvulkanisierten Folienwerkstoffen. Sie betrifft ferner nach diesem Verfahren hergestellte Gegenstände, insbesondere Bademützen oder -kappen aus Gummi.The invention relates to a method for processing unvulcanized film materials. It also concerns after Objects manufactured using this process, in particular bathing caps or caps made of rubber.

Eine der wichtigsten Aufgaben einer Badekappe ist es, das Haar des Benutzers gegen Wasser zu schützen. Zu diesem Zweck werden solche Kappen gewöhnlich auf ihrer Innenseite etwas verdickt, so daß ein wasserdichter Abschluß zwischen der Kappe und dem Kopf des Trägers entsteht. Bei einer in einer Form hergestellten Kappe können solche Verdickungen die Form von durchgehenden, ringsherumlaufenden Wülsten im Bereich des Randes der Mütze haben. Wird eine solche Badekappe aber aus folienförmigem Gummi hergestellt, so muß im Bereich ihres Randes ein getrennter Dichtstreifen an ihrer Innenseite befestigt werden, was normaler? weise mittels eines Klebstoffs erfolgt, wobei sich aber u.a. der Nachteil ergibt, daß dieser Klebstoff häufig durch das Eintauchen und die Benutzung beeinträchtigt wird und sich der Dichtstreifen mit der Zeit löst.One of the most important roles of a swim cap is to maintain your hair protect the user against water. For this purpose, such caps are usually slightly thickened on their inside, so that a watertight seal is created between the cap and the head of the wearer. With one made in a mold Cap, such thickenings can take the form of continuous, circumferential beads in the area of the edge of the cap to have. However, if such a bathing cap is made of film-shaped rubber, a separate one must be used in the area of its edge Sealing strips are attached to their inside, what more normal? wise done by means of an adhesive, but including the The disadvantage is that this adhesive is often impaired by immersion and use and the sealing strip resolves over time.

Eine endere Art der Befestigung ist es, Verarbeitungsschritte bei solchen Kappen vor dem Vulkanisieren vorzunehmen, wenn der Gummi noch klebrig ist. Man kann einen unvulkanisierten Gummistreifen zum Haften an einer unvulkanisierten Kappe bringen, indem man diese Teile zusammenpreßt. Nach einem darauffolgenden Vulkanisieren ist die so gebildete Verbindung im Gebrauch viel widerstandsfähiger als eine Klebeverbindung. Jedoch führen beide Verfahren dazu, daß am Rand der Kappe ein Streifen aus geschichtetem Gummi vorhanden ist; dieser Streifen ist weniger elastisch als die übrige Kappe und ist daher unbequem für den Benutzer, da dieser Streifen wie ein enges Band um seinen Kopf herum liegt.Another type of attachment is processing steps to be carried out on such caps before vulcanizing when the rubber is still sticky. You can use an unvulcanized rubber strip adhere to an unvulcanized cap by pressing these parts together. After a subsequent one Vulcanizing, the connection thus formed is much more resistant in use than an adhesive connection. However lead both methods of having a strip of layered rubber at the edge of the cap; this strip is less elastic than the rest of the cap and is therefore uncomfortable for the user, since this strip is like a tight band around his head lying around.

Es ist daher eine Aufgabe der Erfindung, Nachteile der genannten Verfahren zu vermeiden und insbesondere, ein Verfahren zum Verbinden von Gummifolien aufzuzeigen, mit dem es möglich ist, einen Dichtstreifen fest mit einer Badekappe oder dgl. zu verbinden, ohne einen voluminösen Schichtaufbau zu erhalten.It is therefore an object of the invention to avoid disadvantages of the methods mentioned and, in particular, to provide a method for connecting of rubber sheets, with which it is possible to connect a sealing strip firmly to a swimming cap or the like. without obtaining a voluminous layer structure.

Erfindungsgemäß wird dies bei einem eingangs genannten Verfahren dadurch erreicht, daß der unvulkanisierte Folienwerkstoff so angeordnet wird, daß gegenüberliegende Seiten mit geringem Druck aufeinanderliegen, daß übereinanderliegende Schichten durchschnitten werden, und daß der Werkstoff dann vulkanisiert wird.According to the invention, this is achieved in a method mentioned at the outset in that the unvulcanized film material is so is arranged that opposite sides lie on top of one another with low pressure, that superimposed layers cut through and that the material is then vulcanized.

Nach der Erfindung können nämlich die übereinanderliegenden, unvulkanisierten Gummifolien in überraschender Weise dadurch sicher miteinander verbunden werden, daß man sie lediglich durchschneidet. Die Anwendung dieser Erfindung auf die Herstellung von Bademützen ermöglicht es, einen Wasserabdichtstreifen sicher am Rand der Kappe zu befestigen, und nicht an der Innenseite der Kappe wie bei den bekannten Verfahren. Das erfindungsgemäße Verfahren ermöglicht ferner eine gleichzeitige Verbindung mehrerer solcher Folien miteinander und dadurch das Anbringen von Zierwülsten oder -kanten am Rand einer Bademütze und gleichzeitig mit dem Wasserabdichtstreifen, wie das im folgenden noch im einzelnen beschrieben wird. According to the invention, namely, the superimposed, unvulcanized rubber sheets can be securely connected to one another in a surprising manner in that they are merely cut through. The application of this invention to the manufacture of bathing caps enables a waterproofing strip to be securely attached to the edge of the cap, rather than the inside of the cap as in the known methods. The method according to the invention also enables a simultaneous connection of several such films with one another and thereby the attachment of decorative beads or edges on the edge of a bathing cap and at the same time with the waterproofing strip, as will be described in detail below.

In bevorzugter Weiterbildung des erfindungsgemäßen Verfahrens geht man dabei so vor, daß die übereinanderliegenden Schichten mittels eines erwärmten Schneidwerkzeugs durchschnitten werden. Man erhält hierdurch eine besonders zuverlässige Verbindung der geschnittenen Kanten, und der Schneidvorgang läßt sich sehr leicht durchführen.In a preferred development of the method according to the invention, the procedure is such that the layers lying one on top of the other cut through with a heated cutting tool. This gives a particularly reliable connection of the cut edges, and the cutting process can be carried out very easily.

Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus dem im folgenden beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiel, sowie aus den Unteransprüchen.Further details and advantageous developments of the invention emerge from what is described below and in FIG Embodiment shown in the drawing, as well as from the Subclaims.

Die Fig. 1 und 2 zeigen eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens, und zwar bei der Arbeit. Diese Vorrichtung weist eine Heizspule 1 auf, die zur Erwärmung eines von einem kreisförmigen Amboß 3 angetriebenen Schneidwerkzeugs in Form eines Messers 2 dient. Eine Badekappe 5 ist auf einem Stützglied 4 angeordnet. Ein Dichtstreifen 6, sowie ein von einer Faltvorrichtung 8 in Längsrichtung gefalteter Wulst 7 werden an der Oberseite der Kappe 5 und in der Nähe ihres Randes 10 zugeführt. Durch alle diese zugeführten Schichten wird dabei in der in Fig. 1 angedeuteten Weise das Messer 2 geführt; in Fig. 2 sind der Übersichtlichkeit halber die Heizspule 1 und das Messer 2 nicht dargestellt.1 and 2 show an apparatus for performing the method according to the invention, specifically at work. These The device has a heating coil 1 which is used to heat a cutting tool driven by a circular anvil 3 in the form of a knife 2 is used. A swimming cap 5 is on one Support member 4 arranged. A sealing strip 6 and a bead 7 folded in the longitudinal direction by a folding device 8 are fed at the top of the cap 5 and near its edge 10. Through all of these added layers, guided in the manner indicated in Figure 1, the knife 2; In Fig. 2, the heating coil 1 and are for the sake of clarity the knife 2 is not shown.

Beim erfindungsgemäßen Verfahren wird also der Dichtstreifen in Form eines unvulkanisierten Streifens aus gummiartigem Werkstoff, vorzugsweise aus Gummi, gegen den Außenrand der unvulkanisierten Kappe 5 und parallel zu ihrem Rand 10 gelegt. Dann werden in der in Fig. 1 dargestellten Weise die beiden Schichten in Richtung von der Außenseite zur Innenseite der Kappe 5 längs des Umfangs der Kappe durchschnitten, vorzugsweise wie dargestellt mit dem kreisförmigen Messer 2, das außerhalb der Kappe gehaltert ist und von dem innerhalb der Kappe sich drehenden rotierenden Amboß 3 angetrieben wird, der durch die Gummischichten hindurch gegen das Messer 2 drückt. Die Kappe 5 mit der an ihr befestigten Wasserabdichtung 6 wird dann vulkanisiert und für den Gebrauch umgestülpt.In the method according to the invention, the sealing strip is therefore in the form of an unvulcanized strip of rubber-like material, preferably made of rubber, placed against the outer edge of the unvulcanized cap 5 and parallel to its edge 10. then the two layers are longitudinally in the direction from the outside to the inside of the cap 5 in the manner shown in FIG cut through the circumference of the cap, preferably as shown with the circular knife 2, the outside of the cap is supported and driven by the rotating anvil 3 rotating within the cap, which is driven by the rubber layers pushes through against the knife 2. The cap 5 with the waterproof seal 6 attached to it is then vulcanized and turned inside out for use.
