   Der Trieb p sitzt auf einer Achse pl, welche sich quer über die ganze Einrichtung erstreckt und nahe an ihren Enden je einen Hebel q trägt. Sobald der Trieb p um einen entsprechenden Winkel verdreht wird, veranlasst er auch ein   Ausschwingen der Hebel q.

Die Haken   der Walze k erfassen nun bei geeigneter Drehrichtung der Walze die Enden der Tragstange des Blattes und wickeln letzteres um die Walze.

   The drive p sits on an axis pl, which extends across the entire device and carries a lever q near each end. As soon as the drive p is rotated by a corresponding angle, it also causes the lever q to swing out. If the levers q move upwards. so they lift the foremost sheet so far that the ends of its support rod can collapse into notches r on the upper edge of guide plates which are attached to the side walls of the device. With a suitable direction of rotation of the roller, the hooks of the roller k now grasp the ends of the support rod of the sheet and wrap the latter around the roller.

   During the
Winding the freely hanging sheet piece is pulled over the edge of a board s which extends across the entire device below the roller k and above the suspended sheet stack.
