Zum Trennen von endlosen Warenbahnen, z. B. aus Papier, Watte, Faservliesen, Textilien, Kunststoffolien od. dgl, in einzelne Streifen, wurden bisher gehärtete, auf einer Gegenrolle oder Gegentrommel laufende Schneidrollen oder seitlich aneinanderliegende Messerrollen verwendet. Abgesehen vom schwierigen Schärfen solcher Schneideinrichtungen haben diese noch andere Nachteile. So bilden sich beim längeren Lauf auf der gleichen Stelle in der Gegenwalze oder Gegentrommel kleine Laufspuren, wodurch das Schneidvermögen stark herabgesetzt wird. Besonders bei Warenbahnen, die sehr feine, aber starke Fasern enthalten, wie z. B. Faservliese, Watte, Textilien oder kaschierte Kunststoffbahnen bleiben einzelne Fasern ungeschnitten, wodurch die geschnittenen Streifen in störender Weise zusammenhängen und beim Trennen die Warenränder ausgefranst werden. Besonders schwierig ist das Schneiden von Faservliesen und Watte mittels Messerrollen, da die rotierenden Messer sehr leicht einzelne Fasern — die, da sie nicht gezwirnt und sehr dünn sind — zwischen die Anlageflächen der Messer hineinziehen, so daß sie nicht geschnitten, höchstens gequetscht werden.For separating endless webs of material, e.g. B. made of paper, cotton wool, nonwovens, textiles, plastic films or the like, in individual strips, were previously hardened, running on a counter roller or counter drum Cutting rollers or side-by-side knife rollers are used. Apart from the difficult one Sharpening such cutters has other disadvantages as well. So form at longer Small running tracks run on the same place in the counter roller or counter drum, which means that the Cutting ability is greatly reduced. Especially with webs that have very fine but strong fibers included, such as B. nonwovens, wadding, textiles or laminated plastic sheets remain individual fibers uncut, as a result of which the cut strips are connected in a disruptive manner and when they are separated the edges of the goods are frayed. It is particularly difficult to cut fiber fleeces and Cotton wool by means of knife rollers, since the rotating knife very easily individual fibers - the ones because they are not twisted and very thin - pull them in between the contact surfaces of the knives so that they do not cut, at most squeezed.
Die Erfindung greift auf das Prinzip der Handschere zurück, wobei zwei Messer mit einer mittleren Frequenz gegeneinander schwingen. Derartige Scheren mit schwingenden, vor allem kurzen Messern sind von elektrischen Handscheren, z. B. aus der Blechbearbeitung, bekannt. Durch die Erfindung soll eine verhältnismäßig einfache und trotzdem betriebssichere Schneideinrichtung für endlose Warenbahnen geschaffen werden, die ermöglicht, daß die Warenbahn an einer Vielzahl von Trennstellen geschnitten werden kann.The invention is based on the principle of hand scissors, two knives with a middle Oscillating frequency against each other. Such scissors with swinging, especially short knives are of electric hand shears, e.g. B. from sheet metal working, known. The invention aims to a relatively simple and yet reliable cutting device for endless webs of material be created, which enables the web to be cut at a plurality of separation points can be.
Das Kennzeichen der Erfindung besteht nun darin, die Messer und Gegenmesser mehrerer Trennstellen auf zwei parallel um ihre Achse hin- und herschwingenden, nebeneinanderliegenden Wellen anzuordnen, deren Abstand und Drehwinkel derart bemessen sind, daß die Messer ständig im Eingriff bleiben. Gemäß weiterer Erfindung werden als Messer vieleckige, vorzugsweise quadratisch oder dreieckige, plan geschliffene Platten verwendet, die mit ihrem geometrischen Mittelpunkt auf den Wellen sitzen. Um eine einwandfreie Schneidwirkung zu erzielen, werden sämtliche Messer der einen Welle durch ein federndes Element gegen die anderen Messer gedrückt.The distinguishing feature of the invention is the knife and counter knife of several separation points to be arranged on two parallel shafts that swing back and forth around their axis, the distance and angle of rotation are dimensioned in such a way that the knives are constantly engaged. According to Another invention are as a knife polygonal, preferably square or triangular, flat ground Plates are used that sit with their geometric center on the waves. To a flawless To achieve a cutting effect, all knives of one shaft are supported by a resilient element pressed against the other knives.
Die Erfindung wird im folgenden an Hand der Zeichnung beschrieben. In der Zeichnung zeigtThe invention is described below with reference to the drawing. In the drawing shows

Zwei Wellen 1 und 2 liegen parallel nebeneinander und führen eine oszillierende Schwingung aus, wobei deren Antrieb durch an sich bekannte Exzentertriebwerke erfolgt. Auf der Welle 2 sitzen die quadratischen Schneidplatten 8, die mittels Senkschrauben 6 od. dgl. an festen Bunden 4 angeschraubt sind. Die Bunde 4 werden an den erforderlichen Schnittstellen auf der Welle festgeschraubt. Auf der anderen Welle 1 sitzen die Gegenmesser 7, die in gleicher Weise an Bunden 3 befestigt sind. Diese Bunde 3 sind jedoch axial beweglich und durch einen Keil 5 gegen Verdrehung gesichert. Durch eine Feder 9, die sich gegen einen feststellbaren Stellring 1© abstützt, werden die Messer 7 gegen die feststehenden Messer 8 der anderen Welle angepreßt und bewirken dadurch einen einwandfreien Schnitt.Two shafts 1 and 2 are parallel to each other and carry out an oscillating vibration, the drive being carried out by eccentric drives known per se. The square cutting inserts 8 sit on the shaft 2 and are screwed to fixed collars 4 by means of countersunk screws 6 or the like. The collars 4 are screwed to the required interfaces on the shaft. The counter knives 7, which are fastened to collars 3 in the same way, sit on the other shaft 1. However, these collars 3 are axially movable and secured against rotation by a wedge 5. By means of a spring 9, which is supported against a lockable adjusting ring 1 ©, the knives 7 are pressed against the fixed knives 8 of the other shaft and thereby cause a perfect cut.
Im dargestellten Beispiel sind quadratische Schnittplatten 7 und 8 verwendet. Diese Anordnung hat den Vorteil, daß, sobald die miteinander zusammenarbeitenden Schnittkanten stumpf geworden sind, die Schnittplaiten um 90° verdreht und neue, scharfe Schnittkanten miteinander in Einwirkung gebracht werden. Die zwischen den beiden Schnittkanten durchlaufende Warenbahn wird dadurch einwandfrei geschnitten. Die Frequenz der Schwingungen der beiden Wellen muß hierbei so gewählt werden, daß die in der Zeiteinheit entstehenden Schnittlängen etwas größer sind als die durchlaufende Länge der Warenbahn.In the example shown, square cutting plates 7 and 8 are used. This arrangement has the Advantage that as soon as the cooperating cut edges have become blunt, the Cut planes rotated by 90 ° and new, sharp cut edges brought into action with one another will. The web of material running through between the two cutting edges is therefore flawless cut. The frequency of the oscillations of the two waves must be chosen so that the cutting lengths resulting in the unit of time are slightly larger than the continuous length of the Web.
Die Erfindung ist nicht auf das dargestellte Beispiel beschränkt, es können auch andere Messerformen, z. B. dreieckige Messer oder ovale, exzentrisch befestigte Messer oder Messerklingen, angewendet werden. Auch kann die Anordnung so getroffen werden, daß nur eine Welle schwingt, während dieThe invention is not limited to the example shown, other knife shapes can also be used. z. B. triangular knives or oval, eccentrically attached knives or knife blades are used will. The arrangement can also be made so that only one wave vibrates while the

Instead of the bundles, other devices can also be used for fastening the cutting plates, z. B. those with a clamping effect can be used.
