  Einrichtung an Rollenschneidmaschinen zur Trennung der Schnittränder der einzelnen Bahnen. 



   Die vorliegende Erfindung bezieht sich auf Rollenschneidmaschinen, bei welchen das Schneiden des Papiers in einzelne Bahnen vor dem Aufwickeln auf eine gemeinsame Rollstange erfolgt. 



   Um ein Übereinanderlaufen der geschnittenen Bahnen zwischen Längsschneider und Rollstande zu verhindern, soll nach der vorliegenden Erfindung die Trennung der Schnittränder durch einen auf die Papierbahnen nach dem Schneiden geblasenen Luftstrom erfolgen. 



   Zu diesem Zwecke ist nach F'ig. 1 zwischen dem   Längsschneider a   und der Be- 
 EMI1.1 
   möglichst   so ein   vollkommen   staubfreies Aufwickeln der Rollen. 



   Die getrennte AbfÜhrung der an den beiden Enden der Bahn abfallenden Bänder kann ebenfalls durch Druckluft erfolgen, ferner lässt sich bei Verwendung feuchter Druckluft ein Feuchten des Papiers vor dem Aufrollen mit dem obengenannten Zwecke verbinden, wenn man den Luftstrom auf der ganzen Breite der Papierbahn austreten lässt. 



   Der Austritt der Druckluft kann, unbeschadet der guten Wirkung, über die   gamme   Länge des Rohrs erfolgen oder es kann nach Fig. 2 die Druckluft aus Düsen g austreten, die am Rohr c über den Trennungsstellen der Bahnen d sitzen bezw. nach denselben einstellbar sind. 



   Nach Fig. 3 ist das Rohr c mit einer Längsreihe von Löchern versehen, die durch 
 EMI1.2 
 art, dass die aus den freigelassenen Löchern zwischen den Schiebern ausströmende Druckluft nur die   Tronnungsstellen   der einzelnen Bahnen d trifft. 



   Nach Fig. 4 ist das Rohr c mit einem Längsschlitz ausgeführt und von verstellbaren   Schiebern/über seine tnze Länge bedeckt. Diese Schieber   sind mit   Löchern   versehen, welche sich mit dem Längsschlitz im Rohr c decken ; durch geeignete Einstellung der 
 EMI1.3 
 



   Eine weitere Möglichkeit besteht schliesslich in der Anbringung von Einzelleitungen mit Düsen-Endstücken oder   dergl.,   aus welchen Luft auf die   Trennungsstelh'l1   der   Bahnen   strömt.

  Device on winder to separate the cut edges of the individual webs.



   The present invention relates to slitter-winder machines in which the paper is cut into individual webs prior to being wound onto a common roll bar.



   In order to prevent the cut webs from running over one another between the slitter and the rolling stand, according to the present invention the cutting edges are to be separated by an air stream blown onto the paper webs after cutting.



   For this purpose, according to Fig. 1 between the longitudinal cutter a and the loading
 EMI1.1
   If possible, a completely dust-free winding of the rolls.



   The separate removal of the bands falling at the two ends of the web can also be done by compressed air, and when using moist compressed air, moisturizing the paper before rolling can be combined with the above-mentioned purpose if the air flow is allowed to exit over the entire width of the paper web .



   The exit of the compressed air can, without prejudice to the good effect, take place over the gamme length of the tube or, according to FIG. are adjustable according to the same.



   According to Fig. 3, the tube c is provided with a longitudinal row of holes through
 EMI1.2
 way that the compressed air flowing out of the holes between the slides only hits the separation points of the individual lanes d.



   According to Fig. 4, the tube c is designed with a longitudinal slot and covered by adjustable slides / over its length. These slides are provided with holes which coincide with the longitudinal slot in the tube c; by setting the
 EMI1.3
 



   Finally, a further possibility consists in the attachment of individual lines with nozzle end pieces or the like, from which air flows onto the separation points of the webs.
