Abstract

Disclosed is a toothed edging for textile machines such as combing machines, drafting and opening cylinders for open-end devices and similar, comprising a plurality of bars formed by sawtooth stampings which are disposed next to each other in a parallel manner, are slid in a form-fitting manner onto a holding part by means of a recess that is located in the base area thereof, and are fixed in the longitudinal direction of the holding part by means of cheeks of the supporting segment or the cylinder when placed in the operating position. At least some sections of the recesses (7) of the inventive sawtooth stampings (1) and the cross sections of the holding part (6) are embodied in a T-shaped manner and have two peripheries (8, 10) which run approximately parallel to each other at least in some sections thereof.

Description

Die Erfindung richtet sich auf einen Zahnbesatz für Textilmaschinen, wie Kämm-Maschinen, Verzugs- und Auflösewalzen für Offenend-Vorrichtungen und dergleichen, bestehend aus einer Mehrzahl von Riegeln aus parallel nebeneinander angeordneten Sägezahnstanzteilen, welche mittels einer Ausnehmung in ihrem Fußbereich auf ein Halteteil formschlüssig aufgeschoben sind und in ihrer Gebrauchslage in Längsrichtung des Halteteils durch Wangen des Tragsegments oder der Walze festgehalten sind,The invention is directed to one Tooth trimming for Textile machines, such as combing machines, Distortion and opening rollers for open-end devices and the like, consisting of a plurality of bars from parallel saw tooth punch parts arranged side by side, which by means of a recess in its foot area on a holding part form-fitting are postponed and in their position of use in the longitudinal direction of the holding part by cheeks of the support segment or the roller are,

Ein derartiger Zahnbesatz ist aus der DE 30 07 245 C2 bekannt, wobei das Halteteil im Querschnitt entweder schwalbenschwanzförmig oder annähernd rechteckig mit kreisabschnittförmigen Seitenteilen ausgebildet ist.Such a tooth set is from the DE 30 07 245 C2 is known, wherein the holding part in cross section is either dovetail-shaped or approximately rectangular with circular section-shaped side parts.

Diese Art der Befestigung hat sich in der Praxis außerordentlich gut bewährt, wobei allerdings die seitlichen Teilflächen bzw. Kreissegmente zu Toleranzen bei der Positionierung der zu kämmenden Spitzen führen. Ähnliches gilt für eine Befestigung, wie sie aus der EP 0 839 934 A1 bekannt ist.This type of attachment has proven itself extremely well in practice, although the lateral partial surfaces or circular segments lead to tolerances in the positioning of the tips to be combed. The same applies to an attachment, such as that from the EP 0 839 934 A1 is known.

Da Versuche gezeigt haben, dass eine exakt einheitliche Position der Spitzen der Kämmsegmente für die Erzielung eines optimalen KämmErgebnisses von herausragender Bedeutung ist, liegt der Erfindung die Aufgabe zugrunde, die Geometrie der Befestigung so zu verbessern, dass die Toleranzen erheblich reduziert werden.Since experiments have shown that a exactly uniform position of the tips of the comb segments for achieving an optimal combing result of is of outstanding importance, the invention is based on the object to improve the geometry of the fixture so that the tolerances be significantly reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Ausnehmungen der Sägezahnstanzteile und der Querschnitt des Halteteils wenigs tens abschnittsweise T-förmig mit zwei wenigstens abschnittsweise etwa parallel zueinander verlaufenden Begrenzungsflächen. ausgebildet sind.This object is achieved according to the invention solved, that the recesses of the sawtooth stampings and the cross section of the holding part at least in sections with a T-shape two running at least in sections approximately parallel to each other Boundary surfaces. are trained.

Die erfindungsgemäß vorgesehene T-förmige Konfiguration, d.h. eine Konfiguration mit zwei zueinander parallelen Abschnitten, sorgt dafür, dass die Toleranzen in radialer Richtung, d.h. in derjenigen Richtung, die für die Höhenlage der Spitzen bzw. den radialen Abstand von der Drehachse verantwortlich ist, minimiert werden. Versuche haben gezeigt, dass eine Reduzierung der Toleranzen gegenüber Ausgestaltungen nach dem Stand der Technik auf die Hälfte möglich ist, wodurch das Kämm-Ergebnis verbessert wird.The T-shaped configuration provided according to the invention, i.e. a configuration with two mutually parallel sections, ensures that the tolerances in the radial direction, i.e. in that direction the for the altitude the tip or the radial distance from the axis of rotation is responsible, be minimized. Trials have shown a reduction of tolerances Embodiments according to the prior art are possible in half, whereby the combing result is improved.

Die erfindungsgemäße Ausgestaltung ermöglicht eine kostengünstige einteilige Realisierung der Sägezahnsegmente und eine exakte, ausschließlich formschlüssige Positionierung, ohne dass eine zusätzliche Federbeaufschlagung erforderlich wäre.The configuration according to the invention enables one inexpensive one-piece realization of the sawtooth segments and an exact, exclusive positive Positioning without additional spring loading would be required.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Diese zeigt eine schematische Darstellung eines erfindungsgemäßen Zahnbesatzes.The invention is explained below of a preferred embodiment explained in connection with the drawing. This shows a schematic Representation of a tooth trimming according to the invention.

In der Zeichnung ist ein vollständiges Sägezahnstanzteil 1 dargestellt, welches einen Fußbereich 2 und eine Mehrzahl von Zähnen 3 aufweist. Rechts in der Zeichnung sind weitere Zähne 3 von dahinterliegenden Sägezahnstanzteilen 1 angedeutet, welche über Ausnehmungen 4 und in der Zeichnung nicht dargestellte Verbindungsstäbe einen Riegel 5 ausbilden.In the drawing is a complete sawtooth stamped part 1 shown which is a foot area 2 and a plurality of teeth 3 having. There are more teeth on the right of the drawing 3 of sawtooth stampings behind 1 indicated which recesses 4 and connecting rods, not shown in the drawing, a bolt 5 form.

Die Befestigung dieser Sägezahnstanzteile 1 bzw. einer Mehrzahl von Riegeln 5 an der Kämmwalze einer Kämm-Maschine ist in DE 30 07 245 A1 im einzelnen beschrieben, insbesondere auch die Funktion eines Halteteils 6.The attachment of these sawtooth stampings 1 or a plurality of bars 5 on the combing roller of a combing machine is in DE 30 07 245 A1 described in detail, in particular the function of a holding part 6 ,

Jedes Sägezahnstanzteil 1 weist eine Ausnehmung 7 auf, um die Sägezahnstanzteile 1 bzw. die durch eine Mehrzahl solcher Sägezahnstanzteile 1 gebildeten Riegel 5 auf den Befestigungsabschnitt 8 des Halteteils 6 aufzuschieben.Every sawtooth stamped part 1 has a recess 7 on to the sawtooth stampings 1 or by a plurality of such sawtooth stampings 1 formed latch 5 on the mounting section 8th of the holding part 6 postpone.

Der Befestigungsabschnitt 8 des Halteteils 6 weist eine im Querschnitt T-förmige Konfiguration auf, d.h. zwei bezogen auf die Kämmwalze annähernd tangential und parallel zueinander verlaufende Flächen 9, 10 und zwei bezogen auf die Kämmwalze annähernd radial und parallel zueinander verlaufende Begrenzungsflächen 11.The fastening section 8th of the holding part 6 has a T-shaped configuration in cross section, ie two surfaces which are approximately tangential and parallel to one another with respect to the combing roller 9 . 10 and two boundary surfaces running approximately radially and parallel to one another with respect to the combing roller 11 ,

Im Vergleich zu einer herkömmlicherweise verwendeten schwalbenschwanzförmigen Konfiguration werden hierdurch wesentlich geringere Toleranzen in radialer Richtung (Radius R) erzielt, sodass die Zähne 3 der Sägezahnstanzteile 1 exakt und gleichmäßiger positioniert sind, wodurch ein verbessertes Kämmergebnis erzielt wird.In comparison to a conventionally used dovetail configuration, this results in much smaller tolerances in the radial direction (radius R), so that the teeth 3 the sawtooth stampings 1 are positioned precisely and evenly, which results in an improved combing result.
