Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den bisher bekannten Längsschneidern wird als Uebelstand empfunden, dafs die Schneidewinkel der Messer während des Gebrauches einer steten Veränderung durch Verschleifs unterworfen sind. Um einen glatten Schnitt zu liefern, müssen die Messer nach einiger Zeit geschärft werden.With the previously known longitudinal cutters it is felt as a disadvantage that the The cutting angle of the knives is constantly changing due to wear and tear are subject. In order to provide a smooth cut, the knives will need to be sharpened after a while.

Die vorliegende Erfindung ermöglicht, den Schneidewinkel und die Schärfe bei Kreismessern unverändert zu erhalten, bis dieselben völlig abgenutzt sind. Zu diesem Zweck werden drei Kreismesser vereinigt, und zwar sind diese in Fig ι (Grundrifs) so angeordnet, dafs die Messer CL1 und a2 sich in Gylindermantelflächen abrollen, ihre Achsen liegen in einer senkrecht zur Stoffbahn laufenden Ebene, während die Achse des Messers b1 horizontal und parallel zur Stoffbahn liegt.The present invention enables the cutting angle and sharpness of circular knives to be kept unchanged until they are completely worn out. For this purpose, three circular knives are combined, and these are arranged in Fig. 1 (Grundrifs) in such a way that the knives CL 1 and a 2 roll in cylinder jacket surfaces, their axes lie in a plane perpendicular to the web of material, while the axis of the knife b 1 is horizontal and parallel to the length of fabric.

In Fig. 4 (Grundrifs) rollen die Messer as und at im Kegelmantel ab, ihre Achsen liegen in einer senkrecht zur Stoffbahn laufenden Ebene und bilden mit einander einen Winkel, während die Achse des Messers b2 wiederum horizontal und parallel der Stoffbahn liegt. Die Einwirkung der Messer auf einander ist bei beiden Anordnungen dieselbe und soll an den Fig. 1 bis 3 erläutert werden.In Fig. 4 (Grundrifs) the knives a s and a t roll in the cone shell, their axes lie in a plane running perpendicular to the material web and form an angle with each other, while the axis of the knife b 2 is again horizontal and parallel to the material web . The effect of the knives on one another is the same in both arrangements and will be explained with reference to FIGS. 1 to 3.

Messer b1 ist das treibende, es findet Berührung desselben mit den Messern O1 und a2 in den Linien I1 und I2 statt, es wirken die Messer ax und a2 in diesen Strecken als die Schneiden von Fräsern auf die Schneide des Messers b, ein und schärfen es dauernd unter Wahrung des ursprünglichen Schneidewinkels sowohl von Messer b1 als auch des eigenen. Obwohl die Messer αλ a2 sich mit Messer b1 nur in den Linien I1 und Z2 berühren, wird doch durch die Berührung derselben unter sich, welche bei c in einer, in beiden Mantelflächen liegenden Linie stattfindet, ihr eigener Schneidewinkel erhalten.Knife b 1 is the driving force, it comes into contact with knives O 1 and a 2 in lines I 1 and I 2 , knives a x and a 2 act as the cutting edges of cutters on the cutting edge of the Knife b, and continuously sharpen it while maintaining the original cutting angle of both knife b 1 and your own. Although the knives α λ a 2 touch with knife b 1 only in lines I 1 and Z 2 , their own cutting angle is obtained through the contact between them, which takes place at c in a line lying in both lateral surfaces.

Eines der Messer ax a2, sowie asat kann auch durch eine Schmirgelscheibe ersetzt werden.One of the knives a x a 2 and a s a t can also be replaced by an emery disk.

Die Berührung der Messer CL1 und a2, sowie ag und ai wird, ohne dafs ein Nachstellen erfolgt, durch. Schraubenfedern selbstthätig gesichert. The knives CL 1 and a 2 , as well as a g and a i , are touched without any readjustment being carried out. Helical springs secured automatically.

Patent-Ansprüche:Patent Claims: ι . Ein Längsschneider für Papier- und Stoffbahnen , gekennzeichnet durch die Anordnung dreier Kreismesser derart, dafs die Achse des einen Messers (bx) horizontal und der Stoffbahn parallel liegt, während die Achsen der beiden anderen Messer ((X1 und a2) in einer zur Stoffbahn senkrechten Ebene liegen und entweder parallel zu einander laufen oder einen Winkel mit einander bilden, zum Zweck, ein selbstthätiges Nachschärfen der Messer zu erzielen.ι.
