Description

Die Erfindung betrifft eine Form gemäß dem Oberbegriff des Patent­ anspruches 1, insbesondere Formen zur Herstellung von Gegenständen im Tauchverfahren, wie insbesondere von Handschuhen aus Elastomer. Diese Formen werden in ein Bad aus einem Elastomer getaucht und sobald der die Form bedeckende Überzug, der entsprechend des herzustellen­ den Gegenstands (insbesondere Handschuhs) mehr oder weniger dick ist, getrocknet ist, wird der geformte Gegenstand entformt.The invention relates to a form according to the preamble of the patent Claim 1, in particular molds for the production of objects in the immersion process, such as in particular gloves made of elastomer. These shapes are dipped in an elastomer bath and as soon as the covering covering the mold, which is to be made according to the the object (especially gloves) is more or less thick, is dried, the molded article is removed from the mold.

Zur manuellen oder mechanischen Entformung muß man den freien Rand des Gegenstands in ausreichender Weise greifen können, um auf diesen zum Zwecke der Entformung einen Zug ausüben zu können.For manual or mechanical demolding you have to use the free edge of the object can grasp it sufficiently to be able to pull for the purpose of demolding.

Es handels sich hierbei um einen heiklen Vorgang, der das Greifen eines elastomeren Filmes erfordert, der durch ein Gewebe unterstützt ist oder nicht, um ihn von der Form, sei es durch Einführen von Luft oder von Wasser, derart abzuheben, daß unter Ausübung von Druck der Gegenstand von der Form abgeworfen oder der Film manuell oder mecha­ nisch gegriffen wird, um den Gegenstand von der Form durch Wenden abzuziehen, was der Fall für einen Handschuh ist (eine rechte Form erzeugt einen linken Handschuh). Diese Vorgänge sind schwierig und erfordern im allgemeinen eine manuelle Hilfe.It is a delicate process involving gripping an elastomeric film supported by a fabric is or not to get it out of shape, be it by introducing air or from water, so that under pressure, the Object dropped from the mold or the film manually or mecha nich is gripped to turn the object from the shape subtract what is the case for a glove (a right shape creates a left glove). These operations are difficult and generally require manual help.

Aufgabe der Erfindung ist es, die Entformung, insbesondere die Ent­ formung durch Wenden von Gegenständen von den betrachteten Formen zu vereinfachen und wirksamer zu machen.The object of the invention is the demolding, in particular the Ent shaping by turning objects from the shapes under consideration to simplify and make it more effective.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 enthaltenen Merkmale gelöst. This object is achieved by the in the characterizing part of claim 1 contained features solved.  

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Darin zeigen:An embodiment of the invention is described below with reference to FIG Drawing described. In it show:

Fig. 1 eine Ansicht einer Form nach der Erfindung, Fig. 1 is a view of a mold according to the invention,

Fig. 2 eine Ansicht dieser Form, jedoch um 90° gedreht, wobei ein Teil längs der Linie II-II in Fig. geschnitten ist, sowie Fig. 2 is a view of this shape, but rotated by 90 °, a part being cut along the line II-II in Fig. , And

Fig. 3 eine Schnittansicht längs der Linie III-III von Fig. 1. Fig. 3 is a sectional view taken along the line III-III of Fig. 1,.

Im dargestellten Ausführungsbeispiel ist die Form 1 zur Herstellung von Handschuhen aus einem Elastomer bestimmt. Die Form ist aus Por­ zellan und rund, insbesondere kreisrund im Querschnitt.In the illustrated embodiment, shape 1 is intended for the production of gloves made of an elastomer. The shape is porcelain and round, especially circular in cross-section.

Zweckmäßigerweise weist die Form in der Zone, wo der geformte Hand­ schuh bei der Entformung durch durch Umdrehen bzw. Abziehen durch Um­ wenden gefaßt wird, zwei Vertiefungen a, a 1 auf, die diametral gegen­ überliegend angeordnet und damit praktisch auf jeder Seite der Form angeordnet sind.Advantageously, the shape in the zone where the molded shoe is taken during the demolding by turning around or pulling around to turn, two depressions a, a 1 , which are arranged diametrically opposite and thus arranged practically on each side of the mold are.

Bei der dargestellten Ausführungsform sind diese Vertiefungen langge­ streckt.In the illustrated embodiment, these depressions are langge stretches.

Die nach der Erfindung vorgenommenen Ausbildungen haben zur Folge, daß der Elastomer B, wovon der Handschuh gebildet ist, nach seinem Schwinden bzw. Schrumpfen auf den Vertiefungen a, a 1 entsprechend Fig. 2 gespannt ist, von denen die Abmessungen, insbesondere die Brei­ te und Tiefe, derart gewählt sind, daß unmittelbar und ohne irgend­ eine Schwierigkeit zwischen Form und Handschuh eine Einrichtung einge­ führt werden kann, wie etwa die schematisch mit c bezeichnete Ein­ richtung, die zum Greifen bzw. Fassen und zum Abziehen des Hand­ schuhs zum Zwecke seiner Entformung verwendet wird. Es ist somit nicht mehr erforderlich, auf Mittel zurückzugreifen, die dazu be­ stimmt sind, den Handschuh zum Zwecke des Greifens herzurichten, wo­ raus eine beträchtliche Wirtschaftlichkeit mit Hinsicht auf Material und Zeit resultiert, da selbst manuell das Greifen des Handschuhs einfach und schnell vorgenommen werden kann. The training carried out according to the invention have the consequence that the elastomer B, of which the glove is formed, after its shrinking or shrinking on the recesses a, a 1 is stretched according to FIG. 2, of which the dimensions, in particular the slurry te and depth, are chosen such that a device can be introduced immediately and without any difficulty between the shape and the glove, such as the device schematically designated c , for gripping or gripping and removing the glove for the purpose of it Demolding is used. It is therefore no longer necessary to resort to means which are intended to prepare the glove for the purpose of gripping, which results in considerable economy in terms of material and time, since even manual gripping of the glove can be carried out easily and quickly can.

Zweckmäßigerweise sind die Ränder d der Vertiefungen nicht in einem scharfen Winkel, sondern abgerundet, so daß auf dem hergestellten Handschuh keine Spur oder Abdruck verbleibt. Die Abmessungen der Vertiefungen sind abhängig von dem herzustellenden Gegenstand und den für seine Entfernung verwendeten Mittel gewählt.The edges d of the depressions are expediently not rounded off at a sharp angle, but so that no trace or imprint remains on the glove produced. The dimensions of the depressions are selected depending on the object to be manufactured and the means used for its removal.

Die wie oben beschriebene Erfindung ist nicht auf Formen zur Herstel­ lung von Handschuhen beschränkt und die Formen können auch aus ande­ ren Materialien, wie Metall, Kunststoff u. dgl. hergestellt sein.The invention as described above is not on molds for manufacture limited of gloves and the shapes can also from other ren materials such as metal, plastic and. Like. Be manufactured.
