Abstract

A method of inserting a slide into a frame of elastic plastic, including expanding the frame at two opposite edges. Inserting of the slide and/or the fixing of the slide in position relative to the picture gate is facilitated in that the frame is expanded at both of two opposed edges as the slide is inserted. The slide which has been inserted to its position for projection is fixed with utilization of the elasticity of the plastic in that the expanding of the frame is terminated.

Description

Die Erfindung bezieht sich auf ein Verfahren nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of patent claim 1.

Aus der DE-PS 1 214 898 (vgl. Fig. 8) ist ein Diapositiv-Rähmchen bekannt, dessen Einführschlitz ohne Übergang in eine schlauchartige Aufnahmetasche für das Diapositiv einmündet. Die schlauchartige Ausbildung der Aufnahmetasche vermittelt nicht nur einen Einführschlitz, sondern darüberhinaus auch am entgegengesetzten Ende einen Einführschlitz. Um das Diapositiv trotz der schlauchartigen Ausbildung der Aufnahmetasche festhalten zu können, sind oben und unten Begrenzungsnocken und Nuten vorgesehen. Zur seitlichen Führung des Diapositivs sind Begrenzungsnocken sowie Nuten vorgesehen. Als weitere Führungsmittel für das Diapositiv beim Einführen sind Bohrungen vorgesehen, durch welche auf einer Konfektionierungsmaschine Stifte hindurchgeführt werden, welche dann als Führungsanschläge für das Diapositiv dienen.A slide frame is known from DE-PS 1 214 898 (cf. FIG. 8), the insertion slot of which opens into a tubular receiving pocket for the slide without a transition. The hose-like design of the receiving pocket not only provides an insertion slot, but also an insertion slot at the opposite end. In order to be able to hold the slide in spite of the tubular design of the receiving pocket, limiting cams and grooves are provided at the top and bottom. Limiting cams and grooves are provided for lateral guidance of the slide. As further guide means for the slide during insertion, holes are provided through which pins are passed on a packaging machine, which then serve as guide stops for the slide.

Sind die Diapositiv-Rähmchen jedoch, wie sich aus den übrigen Ausführungsformen der genannten Druckschrift ergibt, mit einer einseitig geschlossenen Tasche ausgebildet, sind Hilfsmaßnahmen erforderlich, um das Diapositiv trotz seiner unvermeidlichen Wölbung bis in Projektionslage, d.h. bis an das Ende der Aufnahmetasche einführen zu können. Die Hilfsmaßnahme besteht darin, daß die in Richtung des Einführens des Diapositivs hintere Bildfensterkante von innen nach außen abgeschrägt ausgebildet ist. Bei Kunststoff-Rähmchen, die extrudiert, gestanzt und verklebt sind, besteht die Hilfsmaßnahme darin, daß die in Einführrichtung des Diapositivs betrachtet hintere Bildfensterkante in der Ebene einer Kunststoff-Folie V-förmig ausgebildet ist.If, however, the slide frames are designed with a pocket closed on one side, as can be seen from the other embodiments of the cited document, auxiliary measures are necessary in order to be able to insert the slide despite its inevitable curvature up to the projection position, ie to the end of the receiving pocket . The auxiliary measure consists in that the rear edge of the picture window in the direction of insertion of the slide is bevelled from the inside to the outside. With plastic frames, which are extruded, punched and glued, the auxiliary measure consists in the fact that the rear window edge viewed in the direction of insertion of the slide is V-shaped in the plane of a plastic film.

Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren derart zu verbessern, daß die genannten Hilfsmaßnahmen entfallen können. Die Lösung der gestellten Aufgabe erfolgt durch das Kennzeichen des Patentanspruchs 1. Der Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß das Diapositiv trotz seiner unvermeidbaren Wölbung ohne zusätzliche Hilfsmaßnahmen bis in seine Projektionslage eingeführt werden kann, und zwar auf an sich bekannten Rahmungsmaschinen sowie unabhängig davon, ob das Diapositiv-Rähmchen im spritzgießverfahren oder in einem Extrudier-und Stanzverfahren hergestellt ist.The object of the invention is to improve the known method in such a way that the auxiliary measures mentioned can be dispensed with. The object is achieved by the characterizing part of patent claim 1. The advantage of the method according to the invention is that, despite its unavoidable curvature, the slide can be inserted into its projection position without additional auxiliary measures, specifically on framing machines known per se and independently of it, whether the slide frame is made by injection molding or in an extrusion and stamping process.

Die Erfindung ist in der nachstehenden Beschreibung anhand verschiedener Ausführungsformen beispielhaft erläutert.The invention is explained in the following description by way of example using various embodiments.

Es zeigen:

  • Fig. 1 und
  • Fig. 2 je einen Diapositiv-Rahmen vor bzw. nach dem Einführen des Diapositivs;
  • Fig. 3 einen weiteren Rahmen während des Einführens des Diapositivs gemäß einer abweichenden Ausführungsform des erfindungsgemäßen Verfahrens sowie
  • Fig. 4 einen Schnitt durch einen Rahmen, der zur Durchführung des erfindungsgemäßen Verfahrens geeignet ist.
Show it:
  • Fig. 1 and
  • 2 each a slide frame before or after insertion of the slide;
  • Fig. 3 shows another frame during the insertion of the slide according to a different embodiment of the method according to the invention and
  • Fig. 4 shows a section through a frame which is suitable for performing the method according to the invention.

Das Diapositiv-Rähmchen 1 aus elastischem Kunststoff ist, wie sich aus Fig. 2 ergibt, an zwei gegenüberliegenden Seiten aufweitbar. Die Einführschlitze-2, 3 sind, wie sich aus Fig. 1 und Fig. 2 ergibt, seitlich bis in die Seitenleisten z.B. 4 zur Bildung eines über die Breite des Rähmchens durchgehenden Spaltes ausgebildet. In der Ausführungsform gemäß den Fig. 1 und 2 werden Keile 5,6 von den Seitenleisten 4, 4a des Rähmchens 1 her in den durchgehenden Spalt der Einführschlitze 2,3 eingesetzt. Der Keil 5 ist mit einer Durchtrittsöffnung 7 für das Diapositiv 8 ausgebildet. Die Einführrichtung für das Diapositiv ist in Fig. 2 durch zwei Pfeile gekennzeichnet.The slide frame 1 made of elastic plastic, as can be seen in FIG. 2, can be expanded on two opposite sides. The insertion slots-2, 3 are as is from Fig. 1 and Fig. 2 results, laterally up to the side strips, for example, 4 to form a gap across the width of the frame. In the embodiment according to FIGS. 1 and 2, wedges 5, 6 are inserted from the side strips 4, 4a of the frame 1 into the continuous gap of the insertion slots 2, 3. The wedge 5 is formed with a passage opening 7 for the slide 8. The direction of insertion for the slide is indicated in FIG. 2 by two arrows.

Die Ausführungsform nach Fig. 3 unterscheidet sich von der bereits beschriebenen dadurch, daß Keile 9 bis 12 in Richtung der eingezeichneten Pfeile, also in Einführrichtung des Diapositivs bzw. umgekehrt dazu in die Einführschlitze eingesetzt werden.The embodiment according to FIG. 3 differs from that already described in that wedges 9 to 12 are inserted into the insertion slots in the direction of the arrows shown, that is to say in the insertion direction of the slide or vice versa.

In beiden Ausführungsformen erfolgt das Einsetzen der Keile in die Einführungsschlitze automatisch.In both embodiments, the wedges are inserted into the insertion slots automatically.

In den Fig. 1, 2, 3 und 4 sind Antipopping-Rippen 13, 14 jeweils verstärkt dargestellt.1, 2, 3 and 4, anti-popping ribs 13, 14 are each shown more intensely.

Zusammenfassend ist festzustellen, daß durch die Erfindung eine Filmklemmung herbeigeführt ist. Zur Funktion der Filmklemmung ist erläuternd auszuführen, daß dabei zwei Aufgaben erfüllt werden:

  • 1. Der Film wird in seiner Lage im Rahmen fixiert. Dies wird durch Verengung des Filmbettes und Klemmung auf zwei der Bildfensterbegrenzungen erreicht.
  • 2. Durch die Klemmung wird eine Vorwölbung des Films erreicht. Dadurch ist ein "Antipopp-Effekt" erzielt.
In summary, it can be stated that the invention brings about a film clamping. For the function of film clamping, it should be explained that two tasks are performed:
  • 1. The film is fixed in its position in the frame. This is achieved by narrowing the film bed and clamping it on two of the picture window boundaries.
  • 2. A protrusion of the film is achieved by the clamping. This creates an "anti-pop effect".
