Spule für Filme, Tonbänder u. dgl.
EMI1.1
<Desc/Clms Page number 2>
Als Material für den Formteil 9 haben sich Azetatharze wie sie z. B. unter der Markenbezeichnung "Delrin" im Handel sind, infolge ihrer guten elastischen Eigenschaften und ihrer hohen Zähigkeit be- währt.
Die Klemmbacke 9 kann insofern von dem dargestellten Beispiel abweichen, als sie relativ dünnwandig ausgebildet und durch eine oder mehrere Rippen versteift werden kann.
Zur Verbesserung des Reibungsverschlusses zwischen Film und Klemmvorrichtung kann die Klemmbacke sowie die Innenfläche des Spulenkernmantels mit einer geriffelten Oberfläche ausgeführt werden.
D die zwei Spulenhälften und der Formteil 9 aus Kunststoff bestehen und daher auf sehr einfache wirtschaftliche Weise hergestellt werden können und auch die Montage der Spule nur einen minimalen Aufwand erfordert, ist eine Fertigung der Spule mit relativ geringen Kosten möglich.
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt.
PATENT ANSPRÜCHE :
1. Spule für Filme, Tonbänder u. dgl. mit einer im Inneren des Spulenkernes angeordneten Klemmvorrichtung, durch welche das durch einen Spalt der Mantelfläche des Spulenkernes eingeführte Filmende fixierbar ist, wobei zwei Klemmbacken vorgesehen sind, von welchen mindestens eine beweglich ist und das Filmende unter der Wirkung von Federelementen gegen die zweite Klemmbacke presst, dadurch gekennzeichnet, dass die Klemmbacke (9a) und die Federelemente (9b, c) als Teile eines einzigen aus elastischem Material, insbesondere aus Kunststoff bestehenden Formteiles ausgebildet ist.

As the material for the molded part 9, acetate resins such. B. under the brand name "Delrin" in the trade, proven due to their good elastic properties and their high toughness.
The clamping jaw 9 can differ from the example shown in that it can be made relatively thin-walled and stiffened by one or more ribs.
To improve the frictional connection between the film and the clamping device, the clamping jaw and the inner surface of the coil core jacket can be designed with a corrugated surface.
D the two coil halves and the molded part 9 are made of plastic and can therefore be manufactured in a very simple, economical manner and the assembly of the coil also requires only minimal effort, the coil can be manufactured at relatively low costs.
The invention is not limited to the illustrated embodiment.
PATENT CLAIMS:
1. Reel for films, tapes, etc. Like. With a clamping device arranged inside the spool core, by means of which the film end inserted through a gap in the outer surface of the spool core can be fixed, two clamping jaws being provided, at least one of which is movable and the film end under the action of spring elements against the second clamping jaw pressed, characterized in that the clamping jaw (9a) and the spring elements (9b, c) are designed as parts of a single molded part made of elastic material, in particular made of plastic.
