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.
