PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich aufThe present invention relates to
Rollenschneidmaschinen, bei welchen das Schneiden des Papiers in einzelne Bahnen vor dem Aufwickeln auf eine gemeinsame RoIlstange erfolgt.Roll cutting machines, in which the cutting of the paper into individual webs before the winding takes place on a common roll bar.
Um ein Übereinanderlaufen der geschnittenen Bahnen zwischen Längsschneider und Rollstange zu verhindern, soll nach der vorliegenden Erfindung die Trennung der SchnittränderTo ensure that the cut webs run over one another between the slitter and roller bar To prevent, according to the present invention, the separation of the cut edges
ίο durch einen auf die Papierbahnen nach dem Schneiden geblasenen Luftstrom erfolgen.ίο by one on the paper webs after Cutting blown airflow done.
Zu diesem Zwecke ist in Fig. ι zwischen dem Längsschneider α und der Belastungswalze b des Rollapparats ein Rohr c mit Löchern oder Düsen angeordnet, aus welchen Druckluft auf die Papierbahnen d strömt, wodurch das Übereinanderlaufen der Schnittränder vor dem Aufrollen auf die gemeinsame Rollstange e verhindert wird. Die ausströmende Luft entfernt gleichzeitig den beim Schneiden entstehenden Staub und ermöglicht so ein vollkommen staubfreies Aufwickeln der Rollen. For this purpose, a tube c with holes or nozzles is arranged in Fig. Ι between the longitudinal cutter α and the loading roller b of the roller apparatus, from which compressed air flows onto the paper webs d , which prevents the cut edges from running over one another before rolling onto the common roller rod e will. At the same time, the air flowing out removes the dust generated during the cutting process, thus enabling the rolls to be wound up completely dust-free.
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.The separate removal of the tapes falling at the two ends of the web can also done by compressed air; can also be used when using moist compressed air Combine wetting the paper before rolling it up with the above purpose if the air flow is allowed to emerge over the entire width of the paper web.
Der Austritt der Druckluft kann, unbeschadet der guten Wirkung, über die ganze Länge des Rohres erfolgen, oder es kann nach Fig. 2 die Druckluft aus Düsen g austreten, die am Rohr c über den Trennungsstellen der Bahnen d sitzen bzw. nach denselben einstellbar sind.The discharge of the compressed air can, notwithstanding the good effect, take place over the entire length of the tube, or it may as shown in FIG. 2 g leak the compressed air from nozzles c on the pipe sitting d over the separation points of the tracks or are using the same set .
Nach Fig. 3 ist das Rohr c mit einer Längsreihe von Löchern versehen, die durch verstellbare Schieber f teilweise abgedeckt sind. Die Einstellung der Schieber erfolgt derart, daß die aus den freigelassenen Löchern zwischen den Schiebern ausströmende Druckluft nur die Trennungsstellen der einzelnen Bahnen d trifft.According to Fig. 3, the tube c is provided with a longitudinal row of holes which are partially covered by adjustable slide f. The setting of the slides is carried out in such a way that the compressed air flowing out of the holes left between the slides only hits the points of separation of the individual tracks d.
In Fig. 4 ist das Rohr c mit einem Längsschlitz ausgeführt und von verstellbaren Schiebern f über seine ganze Länge bedeckt. Diese Schieber sind mit Löchern versehen, welche sich mit dem Längsschlitz im Rohr c decken; durch Einstellung der Schieber kann auch mit dieser Anordnung der Luftstrom bei beliebiger Breite der Einzelbahnen jeweils nach den Trennungsstellen der letzteren geleitet werden.In Fig. 4, the tube c is designed with a longitudinal slot and covered by adjustable slides f over its entire length. These slides are provided with holes which coincide with the longitudinal slot in the tube c; By adjusting the slide, the air flow can also be directed to the separation points of the latter for any width of the individual webs with this arrangement.
Eine weitere Möglichkeit besteht schließlich in der Anbringung von Einzelleitungen mit Düsenendstücken, aus welchen Luft auf die Trennungsstellen der Bahnen strömt.Another possibility is to attach individual lines Nozzle end pieces from which air flows onto the separation points of the webs.
