Spule für das Einspannen von Filmen
EMI1.1
der sie bei Betätigung des Trieblings 12 von der mit ihm gekuppelten Welle 15 durch Vermittlung der Friktionshülse 16 mitgenommen wird, die eine Bohrung des oberen Spulenflansches 2 durchsetzt und in die korrespondierende Bohrung des Spulenkernes eingepresst ist. Mit 17 ist die obere Lagerbüchse der Welle 15 bezeichnet. Beim Einsetzen einer Filmspule wird der Spulenkern entgegen der Pfeilrichtung unter Spannung der Feder 9 verschoben.
Dabei gleitet das untere Ende der Hakenfeder entlang der Konusfläche 13, so dass der Haken 5 aus der Ausnehmung 6 austritt (Pfeil p). Nun wird der Film zwischen Spulenkern und Hakenfeder eingeschoben und die Spule freigegeben, so dass die Feder 9 die Spule wieder in die obere Endlage gegen die Lagerbüchse 17 zurückführt, während die Blattfeder 4 zum Anliegen gegen den Spulenmantel kommt und dabei mit ihrem Haken 5 den Film in der Ausnehmung 6 des Spulenkernes festklemmt.
PATENTANSPRÜCHE :
1. Spule für das Einspannen von Filmen zwischen dem Spulenkern und einer aussen gegen diesen anliegenden Blattfeder, dadurch gekennzeichnet, dass der Spule unter Spannung einer Rückführfeder (9) eine Axialverschiebung erteilt werden kann und dass eine Steuerfläche (13) am Spulenlager (14) vorgesehen ist, welche bei dieser Axialverschiebung die Blattfeder (4) lüftet und zum Festklemmen des eingeführten Filmes wieder gegen den Spulenkern zurückfedern lässt, wenn die Spule in ihre Ausgangsstellung zurückfedert.

Spool for clamping films
EMI1.1
which it is taken along when the pinion 12 is actuated by the shaft 15 coupled to it through the intermediary of the friction sleeve 16, which passes through a bore in the upper coil flange 2 and is pressed into the corresponding bore in the coil core. The upper bearing bush of the shaft 15 is designated by 17. When inserting a film spool, the spool core is moved against the direction of the arrow under tension of the spring 9.
The lower end of the hook spring slides along the conical surface 13 so that the hook 5 emerges from the recess 6 (arrow p). Now the film is inserted between the coil core and the hook spring and the coil is released so that the spring 9 returns the coil to the upper end position against the bearing bush 17, while the leaf spring 4 comes to rest against the coil jacket and the film with its hook 5 stuck in the recess 6 of the coil core.
PATENT CLAIMS:
1. Spool for clamping films between the spool core and a leaf spring lying against it on the outside, characterized in that the spool can be axially displaced under tension by a return spring (9) and that a control surface (13) is provided on the spool bearing (14) which releases the leaf spring (4) during this axial displacement and allows it to spring back against the spool core to clamp the inserted film when the spool springs back into its starting position.
