des Vorschubes von 8 bis o, wo er seine Ausgangsstellung wieder erreicht.
In Fig. 5 sind die bisher gebräuchlichen Bewegungen des Rahmenführers dargestellt.
Angenommen, dass die Stichrcihe, ähnlich wie in Fig. 3, durch die Linie pt-ql dargestellt ist und der Rahmenführer von o1 ausgeht, so bewegt er sich von Beginn der Nadelbewcgung bis pu während die @ Nadel die Fadenschlinge aufnimmt, wird der Rahmenführer nach ql bewegt und gleitet während dieser Bewegung auf dem Werkstück. Das Ergebnis ist, dass das Oberleder vor dem sich bewegenden Rahmenführer gebogen oder gerunzelt wird, wodurch eine Beschädigung des Schuhes und Beeinträchtigung seines guten Aussehens herbeigeführt wird. Von ql wird der Rahmen nach rl bewegt und gelangt während des Vorschubes zur Ausgangsstellung 01 zurück.
PATENT-ANSPRÜCHE :

of the feed from 8 to o, where it reaches its starting position again.
In Fig. 5, the previously common movements of the frame guide are shown.
Assuming that the stitch line, similar to FIG. 3, is represented by the line pt-ql and the frame guide starts from o1, then he moves from the beginning of the needle movement to pu while the needle picks up the thread loop, the frame guide follows ql moves and slides on the workpiece during this movement. The result is that the upper leather is bent or wrinkled in front of the moving frame guide, causing damage to the shoe and impairing its good looks. The frame is moved from ql to rl and returns to the starting position 01 during the advance.
PATENT CLAIMS:
1. Schuhwerknähmascbine with frame guide, characterized in that the frame guide (10) is temporarily moved along the frame in a direction inclined to the feed line.
