    Fig. 12 zeigt eine Ausführungsform der vorderen Zange 41. 



  Die Backen der Zange sind hiebci stärker gebogen und reichen vor dem Anziehen über die.

Die Wirkungsweise der Vorrichtung ist folgende :
Nachdem ein Leisten 21 mit einem Schaft 20 und einer Brandsohle 19 in bekannter Weise versehen wurde, wird er in der aus Fig. 1 ersichtlichen Weise im Rahmen 2 der Vorrichtung auf' dem Lagerstück 17 durch die Spindel   14     festgeklemmt.   Darauf wird die hintere Schaftpartie

    12 shows an embodiment of the front forceps 41.



  The jaws of the pliers are bent more strongly and reach over the before being tightened.

   This embodiment of the front pliers has the advantage that even shafts that have something

The device works as follows:
After a last 21 has been provided with a shaft 20 and an insole 19 in a known manner, it is clamped in the frame 2 of the device on the bearing piece 17 by the spindle 14 in the manner shown in FIG. The rear part of the shaft is then placed on it

This pressing of the parts 32 is now done by the land wheels 25 and the spindles and 24, and that is best first tightened the front and then the side screw spindles. After the locking of the hand lever 56 and the foot step lever 58 for the rear pliers has been released, whereby the pliers under
