Bei mit Kreismessern arbeitenden Maschinen zum Schneiden von Rollen-Pergament, -Papier oder -Stoff ist der Schnitt infolge der Anordnung der Messer und der den abgerollten Theil des Pergaments u. s. w. tragenden Unterlage ein scheerenartiger, ebenso wie bei den meifselartigen Messern, die man zum Schneiden schmaler Streifen verwendet. In beiden Fällen ist eine kneifende Wirkung der Messer auf das zu zertheilende Material unvermeidlich, und dies hat sehr üble Folgen, indem beim Durchlaufen gröfserer Längen das Material nach und nach derart sich verschiebt, dafs es bisher nicht möglich war, beispielsweise vegetabilisches Rollenpergament in gleichmäfsige, vorgeschriebene Breite zu zerschneiden.For machines that work with circular knives for cutting roll parchment and paper or fabric is the cut resulting from the arrangement of the knives and the unrolled part of the parchment and so on, a scissor-like base, as well as the chisel-like base Knives that are used to cut narrow strips. In both cases there is one pinching effect of the knife on the material to be cut inevitable, and this has very bad consequences, in that the material gradually passes through larger lengths shifts in such a way that it was previously not possible, for example vegetable To cut roll parchment into an even, prescribed width.

Um diesen Uebelständen zu begegnen, wende ich Kreismesser an, deren Schneiden nach Art der Rasirmesserschneiden sehr dünn und fein sind und vollständig frei in engen Einschnitten einer festen gewölbten Unterlage laufen. Ueber diese Unterlagen wird das zu zerschneidende Material mit geringer Geschwindigkeit in der Drehungsrichtung des Messers straff gespannt fortgezogen, so dafs durch die feine Messerschneide dasselbe lediglich aufgespalten wird, ohne jede kneifende, den richtigen Lauf störende Scheerwirkung.To counter these evils, I use circular knives, the cutting of which is according to Art The razor blades are very thin and fine and completely free in narrow incisions run on a solid arched surface. About these documents is what is to be cut The material is stretched taut at low speed in the direction of rotation of the knife pulled away so that the fine knife edge only splits it open, without any pinching, shearing effect that interferes with the correct run.

Beiliegende Zeichnung stellt in Fig. 1 einen Querschnitt durch eine nach den vorstehenden Grundsätzen construirte Maschine dar, während Fig. 2 noch eine besondere Ansicht der Schnittvorrichtung der Maschine in gröfserem Mafsstabe veranschaulicht.The accompanying drawing shows in Fig. 1 a cross section through one according to the preceding Principles constructed machine, while Fig. 2 is a special view of the cutting device the machine illustrated on a larger scale.

Der auf eine Walze aufgerollte Stoff B bewegt sich nach der durch einen Pfeil angegebenen Richtung in unzertheilter Breite C zwischen den festen Führungsstangen D weiter, über die feste, gewölbte Unterlage E straff und glatt gespannt hinweg und wird von dem in derselben Richtung rotirenden Kreismesser K hierbei in zwei oder, je nach Anzahl der Kreismesser, mehrere Breiten zerschnitten. Die so hergestellten einzelnen Breiten finden, nachdem sie zunächst wieder zwischen Führungsstangen DD fortgegangen, ihre Aufwickelung auf besonderen Walzen GG1, wie aus Fig. 1 deutlich zu erkennen ist. The fabric B , rolled up on a roller, moves in the direction indicated by an arrow in undivided width C between the fixed guide rods D , stretched tightly and smoothly over the solid, arched base E and is thereby pulled by the circular knife K rotating in the same direction Cut into two or, depending on the number of circular knives, several widths. The individual widths produced in this way, after they have initially moved away again between guide rods DD , are wound up on special rollers GG 1 , as can be clearly seen from FIG. 1.

Die zur Zertheilung des Materials in mehrere Breiten dienende Schnittvorrichtung bildet nun einzig und allein den Gegenstand der vorliegenden Erfindung.The cutting device used for dividing the material into several widths now forms solely the subject matter of the present invention.

Ganz willkürlich ist, wie man im übrigen die Maschine construiren mag, sofern nur dem Material eine genügende straffe und glatte Lage bei seiner Fortbewegung unter dem rotirenden Kreismesser K ertheilt wird. Zum Zweck einer Vermeidung jeder scheerenden und kneifenden Wirkung ist dieses Kreismesser K nach Art eines Rasirmessers aufsen an der Randstelle ganz dünn und sehr scharf geschliffen und rotirt mit grofser Schnelligkeit vollständig frei in einer in der Unterlage E gebildeten, etwa ι bis 2 mm breiten segmentförmigen Rinne a, so dafs das gegen den feinen scharfen Rand des Messers anlaufende, straff gespannte Papier ohne jeden Druck auf die Unterlage gewissermafsen glatt aufgespalten wird. Es wird somitThe way in which the machine is constructed is entirely arbitrary, provided that the material is given a sufficiently firm and smooth position as it moves under the rotating circular knife K. For the purpose of avoiding any shearing and pinching effect, this circular knife K is ground very thin and very sharp on the outside at the edge like a razor knife and rotates with great rapidity completely freely in a segment-shaped groove formed in the base E , about 1 to 2 mm wide a, so that the tightly stretched paper running up against the fine, sharp edge of the knife is, as it were, split open without any pressure on the base. So it becomes

das Material auf der Unterlage E nicht das geringste Bestreben haben, sich seitlich zu verschieben und ungleichmäfsige Breiten zu liefern, denn wegen der straffen Spannung des Materials und der sehr scharfen und feinen, frei laufenden Schneide des Kreismessers kann durch dieses irgend ein Druck auf die Unterlage gar nicht ausgeübt werden.the material on the base E have not the slightest effort to shift sideways and to deliver uneven widths, because because of the tight tension of the material and the very sharp and fine, free-running edge of the circular knife, this can put any pressure on the base not be exercised at all.

An der in der Pfeilrichtung sich drehenden Spindel o, welche durch Stelllager nach Bedarf gehoben oder gesenkt werden kann, können die Kreismesser je nach der zu schneidenden Breite des Stoffes verschoben und auf der Spindel festgestellt werden. On the spindle o rotating in the direction of the arrow, which can be raised or lowered as required by adjusting bearings, the circular knives can be moved depending on the width of the fabric to be cut and fixed on the spindle.
