Description
.; Es ist bekannt, zum Schneiden von Papierstreifen Kreismesser aus dünnem, nachgiebigem Material zu verwenden, die durch eine besondere Spannvorrichtung nach der einen oder anderen Seite gewölbt werden, so' daß ; sie eine flachkeglige Form erhalten. Diese Spannvorrichtungen besitzen jedoch den Nach-■; teil, daß sie nur zum Einspannen einzelner Messer dienen, so daß mit solchen Schneidvorrichtungen nur sehr breite Papierstreifen "geschnitten werden können. Für die Papierspinnerei sind derartige Anordnungen nicht zu verwenden, da die zum Spinnen feiner Papiergarne erforderlichen Streifen eine sehr geringe Breite besitzen müssen. ..; It is known to use circular knives made of thin, flexible material for cutting paper strips, which are curved to one side or the other by a special clamping device, so 'that; they get a flat cone shape. However, these clamping devices have the after- ■ ; part that they only serve to clamp individual knives, so that only very wide paper strips can be cut with such cutting devices. Such arrangements are not to be used for paper spinning, since the strips required for spinning fine paper yarns must have a very small width. .
Gegenstand der Erfindung ist eine Vorrich- ; tung, die das Schneiden von Papier zu Streifen von äußerst geringer Breite ermöglicht. Sie kennzeichnet sich dadurch, daß eine Anzahl der dünnen Kreismesser so auf einer Achse angeordnet ist, daß jedes der Messer zwischen zwei Scheiben von geringerem Durchmesser . . und fiachkegliger Gestalt gepreßt ist, wodurch :. jedes Kreismesser ebenfalls eine flachkeglige ■25 Gestalt, annimmt, Außer der Möglichkeit, Papierstreifen von sehr geringer Breite schneiden zu körinen, besitzt die neue Anordnung, noch den Vorteil, daß die Herstellung wesent-'■■ lieh vereinfacht und ihre Dauerhaftigkeit be-, /30 deutend vergrößert wird. ■'The invention is a device; tung, which involves cutting paper into strips of extremely narrow width allows. she is characterized by the fact that a number of thin circular knives are on one axis is arranged that each of the knives between two discs of smaller diameter . . and fiachkegliger shape is pressed, whereby :. every circular knife also assumes a flat conical shape, besides the possibility of Cutting strips of paper of very narrow width to coring, has the new arrangement, nor the advantage that the production is essential borrowed simplified and reduced their durability, / 30 is significantly enlarged. ■ '
Ein Ausführungsbeispiel der neuen Anordnung ist in der" Zeichnung dargestellt. Fig. 1 zeigt einen Querschnitt und Fig. 2 eine An^ ; 'sieht.1. '-.,' .'. . ■■ ■■ ■ ■ ■ ,,·'■.'. .■;·■■■ .;■ · \ ■■-'. ■■"' .·.'..' ■ Die dünnen Kreismesser a, die zwischen den ■ stärkeren Scheiben & von geringerem Durchmesser und flachkegliger Gestalt eingeklemmt .-. sind, besitzen ursprünglich eine flache Gestalt. : Sie werden in der "Weise . hergestellt und geschärft, daß die flachen Scheiben auf einem 40 Dorn zusammengepreßt und zylindrisch abgedreht oder geschliffen werden. Durch diese \ Maßnahmen erhalten alle Messerscheiben genau .■'■ den gleichen Durchmesser, und die beiden .: Kanten an der Schneide eines jeden Messers 45 bilden genügend schneidfähige, rechte Winkel. . Sind die auf die erwähnte Att eingespannten Messer α durch den Gebrauch einseitig , stumpf geworden, so werden sie derart zwischen ■ den stärkeren Scheiben b angeordnet, daß die 50 ', noch unbenutzte Kante zum Schneiden verwendet wird. Die Messer brauchen also nach •dem. Stumpf werden einer Kante nicht erst : ·.; geschliffen zu werden, . sondern können nach ; dem Umspannen sofort wieder in Gebrauch 55. treten. . ■ ,. . ■... An embodiment of the new arrangement is shown in the "drawing Figure 1 shows a cross section and Figure 2 a to ^; 'sees 1..' -, ,, ■■ ■■ ■ ■ ■ *. '.'.. '■.'.. ■; · ■■■.; ■ · \ ■■ - '. ■■ "'. ·. '..' ■ The thin circular knives a between the ■ thicker disks & of smaller diameter and pinched flat conical shape .-. are originally flat in shape. : They are manufactured and sharpened in such a way that the flat disks are pressed together on a mandrel and then turned or ground cylindrically. Through these measures, all knife disks get exactly the same diameter, and the two edges at the cutting edge of each knife 45 form sufficient cuttable, right angles.. If the clamped on the mentioned Att knife α through the use of one-sided, become dull, they are arranged between ■ the stronger discs b that the 50 ', nor unused edge is used for cutting. So after an edge becomes blunt, the knives do not need to: ·. be ground, but can be used again immediately after; after re-clamping
Ist eine weitere Schärfung der Messer α er- ■. . forderlich, so' werden sie wieder, wie oben . beschrieben, auf einem Dorn zusammengepreßt .;.. und abgedreht. Durch öfteres Schärfen wird 60 nur der Scheibendurchmesser allmählich ver- .. ringert. ; . . : ■ , :. ·'Is a further sharpening of the knife α necessary. . required, so they will be again, as above. described, pressed together on a mandrel.; .. and turned off. Repeated sharpening only gradually reduces the disc diameter. ; . . : ■,:. · '
Messer- und Gegenmesserwelle können gegen-.. einander verstellbar angeordnet.sein. Ebenso können die Kreismesser statt it größerer An- 65 ; zahl auch als Einzelmesser gebraucht werden, : wobei nur zwei flachkeglige Stützscheiben er- ■'■ forderlich sind.- . . ..Knife and counter knife shaft can be arranged so that they can be adjusted in relation to one another. Likewise, the circular knives can be used instead of a larger 65; numbers are used as a single knife: only two flachkeglige supporting discs ■ '■ ER conducive sind.-. . ..
Durch die neue Anordnung wird es ermög- ' licht, daß jeder; ungeübte Arbeiter die ein- 70 zelnen Messer selbst zusammensetzen und 'für. ..··. verschiedene Streifenbreiten einstellen kann. .The new arrangement makes it possible that everyone; untrained workers the 70 assemble individual knives yourself and 'for. .. ··. can set different strip widths. .
