Die Erfindung betrifft eine Vorrichtung zum Schneiden von bahnförmigem Material in gesondert aufzuwickelnde Längsstreifen mit auf Wellen abwechselnd angeordneten, rotierenden Ober- und Untermessern und scheibenförmigen Führungsnutteln, die ohne Spiel in die Zwischenräume zwischen den Längsstreif enwickeln eintauchen.The invention relates to a device for cutting sheet material separately longitudinal strips to be wound up with rotating top and bottom strips alternately arranged on shafts Bedknives and disc-shaped guide nuts that fit into the spaces between develop the longitudinal stripe and immerse it.
Es ist bekannt, Folien aus z. B. Kunststoff in Bänder zu zerschneiden und diese Bänder auf einer Wickelwelle aufzuwickeln. Die hierzu verwendeten Maschinen bestehen in ihren grundsätzlichen Teilen aus zwei mit Kreismessern versehenen Wellen, mit denen die als Breitband angelieferte Folie in schmale Bänder zerschnitten wird.It is known to use foils made of, for. B. to cut plastic into tapes and these tapes on a Wind up the winding shaft. The machines used for this purpose consist in their basic parts of two shafts equipped with circular knives, with which the film delivered as broadband is cut into narrow strips Ribbons being cut.
Bei diesen Schneidverfahren läßt es sich aber nicht vermeiden, daß die auf der Wickelwelle nebeneinander aufgewickelten Bänder ineinanderlaufen, so daß jeweils an der Trennstelle ein Wulst entsteht. Durch diese Wülste werden die Bänder an der Kante verzogen. Die von der Wickelwelle als geschnittener Block abgenommenen Bänder hängen daher in vielen Fällen ineinander fest und müssen mit Gewalt voneinander getrennt werden.In this cutting process, however, it cannot be avoided that the one on the winding shaft next to one another wound tapes run into each other, so that a bead is formed at the separation point. The ribbons are warped at the edge by these bulges. The one from the winding shaft as a cut Block removed tapes are therefore in many cases stuck in one another and have to be forcibly separated from one another be separated.
Es ist weiterhin bekannt, zum Schneiden von Bändern Schneidrollen zu verwenden, die einseitig auf eine zylindrische Gegenwalze aufgepreßt werden und dabei die Folie gegen die genannte Walze drücken und zerschneiden. Durch das Aufpressen der Folie auf die-Gegenwalze werden aber an den beiden Bandkanten starke plastische Verformungen erzeugt. Diese Verformungen sind zusammen mit den sich ergebenden Breitentoleranzen der Einzelstreifen ein großer Nachteil für die Verwendung der Streifen in hochwertigen Geräten, zumal die geschnittenen Bänder nicht geführt werden.It is also known to use cutting rollers for cutting tapes that are on one side a cylindrical counter roller are pressed on and thereby press the film against said roller and cut up. When the film is pressed onto the counter roller, however, there are two edges of the belt strong plastic deformations generated. These deformations are along with the resulting Width tolerances of the individual strips a major disadvantage for the use of the strips in high quality Devices, especially since the cut tapes are not guided.
Die gleichen Störungen an den Bandrändern ergibt eine andere bekannte Schneidvorrichtung mit ebenen Schneidmessern ohne Bandführung.The same disturbances at the tape edges results in another known cutting device with planar ones Cutting knives without tape guide.
In einer bekannten Vorrichtung werden einseitig schneidende Rollmesser verwendet, wobei die Bänder auseinandergezogen und unter ungleichmäßige Spannungen gesetzt werden. Eine derartige Vorrichtung ist zur Herstellung hochwertiger Bänder nicht verwendbar, weil die Bandkanten verzogen werden und kein einwandfreies Aufwickeln der einzelnen Bänder mehr möglich ist. Wird wie in einer anderen bekannten Vorrichtung der Schnitt durch stumpfe Drähte oder Messer erzeugt, so können sich erst recht keine unveränderten Bandränder ergeben.In a known device, single-sided cutting circular knives are used, the tapes pulled apart and placed under uneven tension. Such a device cannot be used for the production of high-quality ribbons because the ribbon edges are warped and the individual tapes can no longer be properly wound up. Is known as in another Apparatus that cuts through blunt wires or knives, certainly none unchanged tape edges result.

mung des Werkstoffes an den Bandrändern vermieden wird und beide Bandkanten gleichartig geschnitten sind. Schneidet das Messer von oben, d. h. zuerst durch die harte aufgebrachte Schicht, so ergibt sich eine anders verformte Schnittfläche, als wenn das Messer von unten zuerst durch die relativ weiche unbeschichtete Folie und erst danach durch die stark verschleißend wirkende Beschichtung geführt wird. Diese Aufgabe wird mit einer Vorrichtung gelöst, bei der die Messer der Obermesserwelle als scheibenförmige Führungsmittel für die aufzuwickelnden Längsstreifen ausgebildet sind und die Obermesserwelle gegen die Längsstreifenwickel schwenkbar angeordnet ist. Die Dicke der Obermesser und der in die Untennesser eingreifenden Abfallabstreifkämme entspricht dem Abstand der Untermesser.tion of the material at the belt edges is avoided and both belt edges are cut in the same way are. Cuts the knife from above, i.e. H. first through the hard applied layer, so it results a differently deformed cut surface than when the knife from below first through the relatively soft uncoated Foil and only then passed through the highly abrasive coating. This object is achieved with a device in which the knives of the upper knife shaft are disc-shaped Guide means are formed for the longitudinal strips to be wound and the upper cutter shaft is arranged pivotably against the longitudinal strip winding. The thickness of the upper knife and the one in the Waste scraper combs engaging the lower cutter corresponds to the spacing of the lower cutter.
Das von der Rolle ablaufende Folienband wird durch gleichzeitiges Herausschneiden von gegenüber der Bandbreite schmalen Abfallstreifen in Bänder aufgeteilt, und die Bänder werden unter seitlicher Führung nebeneinander in den Abfallstreifen entsprechenden Abständen unabhängig von den gesondert aufgespulten Abfallstreifen und unabhängig voneinander gleichzeitig aufgewickelt.The film strip running off the roll is made by cutting it out from the opposite side at the same time The ribbon narrow strips of waste are divided into ribbons, and the ribbons are underneath sideways Guide side by side in the waste strips corresponding distances regardless of the separately wound up waste strips and independently of each other wound up at the same time.
Durch die Obermesser wird demnach aus der Folie jeweils ein schmaler Abfallstreifen herausgeschnitten, und die schmalen Obermesser werden gleichzeitig zur Führung des Bandes auf der Wickelwelle mit herangezogen. A narrow waste strip is cut out of the film by the upper knife, and the narrow top knives are also used to guide the tape on the winding shaft.
Die schmalen Obermesser tauchen auf der einen Seite in die Zwischenräume zwischen den Untermessern ein und schneiden dadurch die zwischen den Messern durchlaufende Folie in Bänder. Zwischen jeweils zwei nebeneinanderliegenden Untermessern bleibt dabei ein Abfallstreifen übrig. Diese Abfallstreifen werden durch eine aus einzelnen gekrümmtenThe narrow upper knives plunge into the spaces between the lower knives on one side and cut the film running between the knives into ribbons. Between a waste strip is left over for every two lower knives lying next to each other. These rubbish strips are curved by a single
