gesetzt, dass der Streifen von oben abläuft, wie Fig. 1 der Zeichnung zeigt, 80 ist augenscheinlich der Winkel des Streifens beim Vorbeileiten an der Führung 19 viel spitzer, als wenn der Streifen von unten abläuft. Infolgedessen ist auch ein grösserer Reibungswiderstand bei der Bewegung des Streifens vorhanden, und es kann vorkommen, dass die
EMI2.1
böcken 16 ruhen, angebracht und kann auch unter Federpressung nachgiebig sein. Wenn die Fortschaltvorrichtung arbeitet, wird das Papier zwischen der Leitrolle 18 und der Fortschaltvorrichtung straff und hebt die Walze 20a an, die mit einer gewissen Schwere auf dem Streifen liegt.
Sobald die Type sich von der Anschlagschiene zurückbewegt und das Papier loslässt, wird das Papier durch das Gewicht der Walze herabgedrückt und etwas über die Leitrollen 17, 18 gezogen. Auf diese Weise wird der Reibungswiderstand des Papierstreifens, der vielleicht wegen des spitzen Winkels nach der Führungsleiste 19 hin entstanden ist, aufgehoben und eine genügende Bauschung des Papieres gesichert. Bei Benutzung der Walze 20a kann die obere Führung 17 fortgelassen und das Papier unmittelbar von der Leitrolle 18 unter die Walze 20a geführt werden (Fig. 4).

Assuming that the strip runs off from above, as shown in FIG. 1 of the drawing, 80 the angle of the strip is evidently much more acute when it passes the guide 19 than if the strip runs off from below. As a result, there is also greater frictional resistance in the movement of the strip, and it can happen that the
EMI2.1
blocks 16 rest, attached and can also be resilient under spring compression. When the indexing device works, the paper between the guide roller 18 and the indexing device becomes taut and lifts the roller 20a, which lies with a certain weight on the strip.
As soon as the type moves back from the stop rail and lets go of the paper, the paper is pressed down by the weight of the roller and pulled slightly over the guide rollers 17, 18. In this way, the frictional resistance of the paper strip, which may have arisen because of the acute angle towards the guide bar 19, is eliminated and sufficient bulk of the paper is ensured. When using the roller 20a, the upper guide 17 can be omitted and the paper can be guided directly from the guide roller 18 under the roller 20a (FIG. 4).
