Description

Vorrichtung zur Befestigung von Filmen am Filmspulenkern Zusatz zum Patent 715 961 Die Erfindung betrifft eine weitere Ausgestaltung und Verbesserung der Vorrichtung, nach Patent 7 15 96 i zur Befestigung von Filmen am Filmspulenkern mit keilförmigem Spulenschlitz, bei der das Filmende im Spulenschlitz zwischen den stark rauhen Oberflächen eines gefalteten Blattes eingeklemmt ist.Device for attaching films to the film spool core Addendum to patent 715 961 The invention relates to a further embodiment and improvement of the device according to patent 7 1 5 96 i for attaching films to the film spool core with a wedge-shaped spool slot, in which the film end in the spool slot between the very rough Surfaces of a folded sheet is pinched.

Erfindungsgemäß ist das aus steifem Werk-Stoff, beispielsweise Metallblech, bestehende gefaltete Blatt an seiner Falzkante zu einer zylindrischen Erweiterung aufgebogen, die beim Eindrücken des gefalteten Blattes in den keilförmigen Schlitz, die Schenkel des 137attes zusammendrückt. An den freien Enden der Schenkel kann das Blatt nach außen umgelegte Lappen haben, die das völlige Herausziehen der Klemmvorrichtung aus dem S.pulenschlitz verhindern. Um die Klemmvorrichtung an beiden Mündungen des Spulenschlitzes erfassen zu können, bat die Spulenachse am Spulenschlitz zweckmäßigerweise kugelabschnittförmige Ausdrehungen.According to the invention, this is made of stiff material, for example sheet metal, existing folded sheet at its folded edge to a cylindrical extension when the folded sheet is pressed into the wedge-shaped slot, compresses the legs of the 137attes. At the free ends of the legs can the sheet have flaps folded outwards so that the clamping device can be pulled out completely from the S. reel slot. To the clamping device at both mouths of the To be able to capture the bobbin slot, the bobbin axis at the bobbin slot expediently asked spherical segment-shaped recesses.

Eine Ausführungsform der Erfindung ist beispielsweise in den Abbildungen dargestellt. Abb. i zeigt die Spule in Seitenansicht in Richtung des Spulenschlitzes.An embodiment of the invention is for example in the figures shown. Fig. I shows the coil in side view in the direction of the coil slot.

Abb.2 zeigt einen Längsschnitt durch die Spule, Abb.3 einen Querschnitt, Abb. q. in Schrägansicht das U-förmig gefaltete Klemmstück.Fig.2 shows a longitudinal section through the coil, Fig.3 shows a cross section, Fig.q. the U-shaped folded clamping piece in an oblique view.

Das U-förmig gefaltete Blatt B besteht aus einem auf der Innenseite aufgerauhten Metallblech, dessen Biegungskante B2 zylinderförmig aufgeweitet ist. An den Enden der U-Schenkelflächen hat das Blatt je einen kleinen überstehenden Ansatz B3, der nach dem Einsetzen des Blattes B in den keilförmigen Spulenschlitz S von der weiteren Seite aus rechtwinklig nach außen umgebogen wird (vgl. Abb. 3). Der Spulenscbaft hat in der Mitte jeder Schlitzöffnung eine kugelabschnittförmige bzw. zylindrische Ausdehnung S1, mittels deren man mit zwei Fingernägeln auf der einen Seite die Aufweitung B2 hintergreifen kann, um das U-förmig gefaltete Blatt B aus dem Schlitz herauszuziehen, bis die Ansätze Bg auf der anderen Seite an die Ausdrehizng des Spulenschaftes anschlagen, wodurch das vollständige Herausziehen des Blattes verhindert wird. In dieser in der Abb.3 dargestellten Stellung kann das Ende des Films F zwischen die Backen des Blattes B von der engeren Schlitzseite aus eingeführt werden. Wenn die Aufweitung B2 des Blattes B dann in die weitere Seite des Spaltes hineingedrückt wird, so wird das Filmende zwischen den Backen des Blattes B festgekl-,mmt.The U-shaped folded sheet B consists of one on the inside roughened sheet metal, the bending edge B2 of which is expanded in a cylindrical shape. At the ends of the U-leg surfaces, the sheet has a small protruding one Approach B3, after inserting sheet B into the wedge-shaped spool slot S is bent outwards at right angles from the other side (see Fig. 3). The coil shaft has a spherical segment-shaped shape in the center of each slot opening or cylindrical extension S1, by means of which one can with two fingernails on the one side can reach behind the widening B2 to the U-shaped folded sheet B out of the slot until the lugs Bg on the other side touch the Knock out the spool shaft, thereby pulling it out completely of the sheet is prevented. In this position shown in Fig the end of film F between the jaws of sheet B from the narrower side of the slot to be introduced from. If the widening B2 of the sheet B then into the further Side of the gap is pushed in, the end of the film will be between the jaws of sheet B clamped, mmt.
