Abstract

In a film cassette comprising two flat shells facing each other with their hollow sides, an annular, planar film disc (1), connected to a plastic hub (2) is rotatably mounted. A method of connecting the film disc (1) to the hub (2) consists in that axially directed cams (2b) or ribs are provided on the hub (2) and are pressed by means of hot forming over edges of the film disc (1) present in the region of the hub. <IMAGE>

Description

Verfahren zum Befestigen einer Filmscheibe an einer in eine Kassette ein-Method of securing a film disc to a cassette a-

setzbaren Nabe Die Erfindung betrifft ein Verfahren zum Befestigen einer flachen, ringförmigen Filmscheibe an einer drehbar in eine flache Kassette einsetzbaren Nabe aus Kunststoff.settable hub The invention relates to a method of fastening a flat, annular film disc on a rotatable in a flat cassette insertable hub made of plastic.

Bei einer bekannten Anordnung dieser Art wird die Filmscheibe zwischen eine ebene Fläche der Nabe und einen gesonderten Klemmring eingespannt.In a known arrangement of this type, the film disc is between a flat surface of the hub and a separate clamping ring clamped.

Der Erfindung liegt die Aufgabe zugrunde, bei der Befestigung der Filmscheibe an der Nabe ein zusätzliches Klemmteil zu vermeiden und den Befestigungsvorgang einfach und unkompliziert ablaufen zu lassen.The invention is based on the object in the attachment of the Film disk on the hub to avoid an additional clamping part and the fastening process easy and uncomplicated to run.

Diese Aufgabe wird erfindungsgemäß gelöst durch das Verfahren nach dem Hauptanspruch. Mögliche Varianten dieses Verfahrens sind den Unteransprüchen entnehmbar.This object is achieved according to the invention by the method according to the main claim. Possible variants of this method are the dependent claims removable.

Die Erfindung wird anhand von Zeichnungen näher erläutert. Es zeigen Fig. 1 eine Draufsicht auf ein Ausführungsbeispiel einer erfindungsgemäß hergestellten Nabe mit Filmscheibe, Fig. 2 einen Schnitt durch die Anordnung nach Fig. 1 gemäß der Schnittlinie II - II.The invention is explained in more detail with reference to drawings. Show it Fig. 1 is a plan view of an embodiment of one produced according to the invention Hub with film disc, Fig. 2 shows a section through the arrangement according to Fig. 1 according to the section line II - II.

Die Erfindung geht aus von einer aus zwei flachen, mit ihren hohlen Seiten einander zugewandten Schalen bestehenden Filmkassette, in die eine mit einer ebenen, kreisringförmigen Filmscheibe verbundene Kunststoffnabe drehbar eingesetzt ist. Dabei geht es um eine besonders teilesparende und einfache Befestigung der Filmscheibe 1 an der Nabe 2. Die Nabe 2 weist eine ebene Kreisringfläche 2a auf, auf der der innere Randbereich der Filmscheibe 1 aufliegt. Auf dieser Kreisringfläche 2a sind in gleichmäßigen Winkelabständen kleine kreisringsektorenförmi ge Nocken 2b vorgesehen, nämlich aus Kunststoff angeformt. Die Filmscheibe 1 weist in ihrem inneren, auf der Ringfläche 2a zur Auflage kommenden Randbereich zu den Nokken 2b komplementäre Ausschnitte la auf. Zur Verbindung von Filmscheibe 1 und Nabe 2 werden die Ausschnitte la über die Nocken 2b gesteckt. Dann werden die Nocken 2b warmverformt bzw. gegen die Filmscheibe 1 warm verpreßt, so daß sie über die Kanten der Ausschnitte la überstehende nietkopfähnliche Köpfe bekommen. Damit ist die Filmscheibe 1 ohne zusätzliche Befestigungsteile und mit einem Preß- oder Stempelvorgang, wie er auch zum Andrücken eines zusätzlichen Befestigungsrings notwendig wäre, fest mit der Nabe 2 verbunden.The invention is based on one of two flat ones, with their hollow ones Sides facing shells existing film cassette, in one with a flat, circular film disk connected plastic hub inserted rotatably is. It is about a particularly simple and parts-saving attachment of the Film disk 1 on the hub 2. The hub 2 has a flat circular ring surface 2a, on which the inner edge area of the film disk 1 rests. On this circular ring area 2a are small circular ring sector-shaped cams at regular angular intervals 2b provided, namely molded from plastic. The film disc 1 has in its inner edge area coming to rest on the annular surface 2a for the cams 2b complementary cutouts la. To connect the film disc 1 and hub 2 are the cutouts la inserted over the cams 2b. Then the cams 2b are thermoformed or hot-pressed against the film disk 1 so that it over the edges of the cutouts la get protruding heads resembling rivet heads. The film disk 1 is thus without additional fasteners and with a pressing or stamping process, like him to press an additional fastening ring would be necessary, firmly with the Hub 2 connected.

An die Stelle der bogenförmigen Nocken 2b und Ausschnitte la könnten auch auf einem Kreis, vorzugsweise in gleichmäßigen Winkelabständen, angeordnete Kunststoffnietstifte an der Nabe 2 und korrespondierende Löcher in der Filmscheibe 1 vorgesehen sein, wobei bei der Warmverformung die Stifte zu Nietköpfen, die die Ränder der Löcher übergreifen, geformt werden.Instead of the arcuate cams 2b and cutouts la could also arranged on a circle, preferably at regular angular intervals Plastic rivet pins on the hub 2 and corresponding holes in the film disc 1 may be provided, with the hot forming the pins to rivet heads that the Reach over the edges of the holes to be shaped.

Die gleiche Wirkung kann aber auch erzielt werden, wenn an die Stelle der Nocken 2b eine ringförmige Rippe tritt, an deren Außenumfang die Innenkante der Filmscheibe nahezu anliegt, wobei dann die Innenkante der Filmscheibe bei der Warmverformung der Rippe umbördelt wird.The same effect can also be achieved when taking the place the cam 2b enters an annular rib, on the outer circumference of which the inner edge the film disk almost rests, in which case the inner edge of the film disk at the Hot deformation of the rib is crimped.
