Description

Der Lichtpausapparat A besteht aus der biegsamen Platte B, dem .Spanndraht C" und der Aufspannvorrichtung D. D ist an den beiden Kanten der Plattet verschiebbar ange-5 ordnet. Er besteht aus drei Teilen: der Feststellvorrichtung E mit Druckschraube, der federnden Verbindung F und der Klemmschiene G. Letztere greift über die ganze Platte hinweg und besteht aus zwei Teilen: derThe blueprint apparatus A consists of the flexible plate B, the "tensioning wire C" and the jig D. D is slidably arranged on both edges of the plate. It consists of three parts: the locking device E with pressure screw, the resilient connection F. and the clamping rail G. The latter extends over the entire plate and consists of two parts: the

ίο Platte mit umgebogener Kante und der U-förmigen Druckschiene K; letztere ist an einem Ende von G drehbar befestigt und am anderen Ende mittels des Überwurfes L feststellbar.ίο plate with bent edge and the U-shaped pressure rail K; the latter is rotatably attached to one end of G and lockable at the other end by means of the cap L.

Das Pauspapier und die durchscheinende Zeichnung werden, wie der Streifen M zeigt, auf die umgelegte Kante G gelegt und dann mittels Druckschiene A' festgeklemmt. Ein schmaler Rand genügt, um die Papiere genügend festzuhalten. Nachdem dies geschehen ist, wird die Klemmvorrichtung E festgestellt und dann die Platte A gebogen; wodurch die Papiere faltenlos aufgespannt werden. Die federnde \7erbindung F verhindert das Zerreißen des Papiers. AVünscht man eine Schutzplatte aus Zelluloid usw. zu verwenden, so wird diese genau wie das Papier eingespannt und die Zeichnung lose daruntergelegt.The tracing paper and the translucent drawing are, as the strip M shows, placed on the folded edge G and then clamped by means of the pressure rail A '. A narrow margin is enough to hold the paper firmly in place. After this has been done, the clamping device E is fixed and then the plate A is bent; whereby the papers are stretched without creases. The resilient \ 7 Getting Connected F prevents the tearing of the paper. If you wish to use a protective plate made of celluloid, etc., this is clamped in exactly like the paper and the drawing is loosely placed underneath.

Die elastische Verbindung der beiden Spannteile gleicht die dem Zelluloid eigene starke Ausdehnung bei Erwärmung aus. Bei Be- 30 nutzung dieser Platten genügt es, nur die eine Seite der Klemmvorrichtung lösbar zu machen.The elastic connection of the two tensioning parts resembles the strong one inherent in celluloid Expansion when heated. When using these plates, just one is sufficient To make side of the clamping device releasable.
