    Aufwickeltrommel für   eiserne Rolladen. 



   Die Erfindung betrifft eine Aufwickelvorrichtung für Rolladen aus Metallplatten, die mittels Ausbiegungen an ihren Rändern ineinanderhängen. Die Erfindung besteht darin, dass am Umfange der Aufwickeltrommel Aussparungen vorgesehen sind, in welche sich diese Ausbiegungen des aufgewickelten Rolladens einlegen. Durch diese Einrichtung wird der Umfang der Aufwickelwalze beim Aufwickeln der ersten Schicht fast nur um die Blechdicke der Metallplatten vergrössert. 



   Auf der Zeichnung ist die Aufwickeltrommel nach der Erfindung mit dem dazugehörigen Rolladen im Querschnitt dargestellt. 



   Der Rolladen besteht, abgesehen von dem Aufhängehaken a und dem Endstreifen b, aus gleich grossen Metallstreifen c mit je zwei kreisförmigen Randausbiegungen   d   und e, die beide an der gleichen Seite des Metallstreifens e liegen, also bei der Darstellung der Abbildung beide nach rechts hin abgebogen sind. Die Platten hängen mit diesen Ausbiegungen in bekannter Weise ineinander.

   Die im Aufnahme-   kasten fangeordnete Aufwickeltrommel g   ist mit Ausschnitten   h   versehen, derart, dass sich beim Aufwickeln von der zunächst aufgewickelten Schicht des   Rolladens sämtliche   kreisförmigen Ausbiegungen cl und e in diese Ausschnitte einlegen, so dass durch diese Schicht fast nur eine Durchmesser-Vergrösserung der Aufwieklung um die Stärke der Metallstreifen c entsteht.

    Winding drum for iron shutters.



   The invention relates to a winding device for roller shutters made of metal plates which hang into one another by means of bends at their edges. The invention consists in that recesses are provided on the circumference of the winding drum, into which these bends of the rolled up roller shutter are inserted. With this device, the circumference of the winding roller is increased almost only by the sheet thickness of the metal plates when the first layer is wound up.



   In the drawing, the winding drum according to the invention with the associated roller shutter is shown in cross section.



   Apart from the suspension hook a and the end strip b, the roller shutter consists of metal strips c of the same size with two circular edge bends d and e, which are both on the same side of the metal strip e, i.e. both bent to the right in the illustration in the illustration are. The plates are interlocked with these bends in a known manner.

   The winding drum g, which is arranged in the receiving box, is provided with cutouts h, in such a way that when the first rolled-up layer of the roller shutter is wound up, all of the circular bends cl and e are inserted into these cutouts, so that this layer almost only increases the diameter of the There is an increase in the strength of the metal strips c.
