KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Streckwalzen, wie solche in den Streckwerken der Nadelstabstrecken, Nadelwalzenstrecken, Kämm-Maschinen und in ähnlichen Maschinen zur Verwendung kommen, insbesondere solche, die mit Lederüberzügen versehen sind, werden häufig ausbesserungsbedürftig, so daß sie ausgewechselt werden müssen, wobei das Herausheben und Wiedereinlegen der Streckwalzen aus ihren Lagern einen großen Zeitaufwand erfordert, so daß die Betriebsstörung eine recht beträchtliche ist.Draw rollers, such as those in the drawing units of the needle bar draw frames, needle roller draw frames, Combing machines and similar machines are used, in particular those that are provided with leather covers are often in need of repair, so that they must be replaced, with the lifting and reinsertion of the Stretching rolls out of their bearings requires a lot of time, so that the malfunction a sizable one.

Um diesen Übelstand auf ein möglichst geringes Maß zu beschränken, wird der Streckzylinder nach vorliegender Erfindung dreiteilig gemacht, derart, daß der mittlere, die Arbeitsfläche aufnehmende Teil von den beiden in den Lagern ruhenden Teilen gelöst werden kann, so daß es nur nötig ist, jeweilig den mittleren Teil auszuwechseln.In order to limit this inconvenience to the lowest possible level, the stretching cylinder made according to the present invention in three parts, so that the middle, the work surface receiving part can be released from the two parts resting in the bearings, so that it is only necessary to the respective replace the middle part.

Auf beiliegender Zeichnung zeigt Fig. 1 einen Streckzylinder bisher bekannter Ausführungsform. Fig. 2 zeigt den neuen geteilten Zylinder und Fig. 3 den Zylinder einer Kämm-Maschine, an welcher die Erfindung angewendet worden ist. Fig. 4 zeigt eine Verbindungsstelle des mittleren Teiles mit dem äußeren und Fig. 5 und 6 zeigen Abarten der Verbindungsweise.In the accompanying drawing, FIG. 1 shows a stretching cylinder of a previously known embodiment. Fig. 2 shows the new split cylinder and Fig. 3 the cylinder of a combing machine, to which the invention has been applied. Fig. 4 shows a junction of the middle part with the outer and Figs. 5 and 6 show variants of the connection.

Die Verbindung des lösbaren mittleren Teiles α mit den Endteilen b des Zylinders kann beliebig ausgeführt werden; sie geschieht zweckmäßig durch einen an einem Teil sitzenden Zapfen c, welcher in eine entsprechende Aussparung d des anderen Teiles eingreift und durch einen quer durchgehenden Bolzen gehalten werden kann. Die Verbindung kann jedoch auch in mancherlei anderer Art bewirkt werden, wie Fig. 5 und 6 zeigen.The connection of the detachable middle part α with the end parts b of the cylinder can be carried out in any way; it is expediently done by a pin c seated on one part, which engages in a corresponding recess d of the other part and can be held by a transverse bolt. However, the connection can also be effected in a number of other ways, as shown in FIGS. 5 and 6.

Der Mittelteil α kann bei einer etwaigen Beschädigung zur Ausbesserung oder Erneuerung oder auch zur Reinigung bequem nach Lösen der Verbindung mit den Endteilen abgenommen werden, ohne daß es einer Störung der Getriebe, Schutzvorrichtungen oder der Lager oder einer Lösung der Schrauben derselben bedarf. Die Einrichtung hat den Vorteil, daß man bei der Reinigung, beim Ausbessern, Abdrehen oder sonstigen Bearbeiten des fehlerhaft gewordenen Zylinders es mit einem kleineren und leichteren Gegenstand zu tun hat.The middle part α can easily be removed for repair or renewal or for cleaning after loosening the connection with the end parts in the event of any damage, without disturbing the gears, protective devices or bearings or loosening the screws of the same. The device has the advantage that you have to do with a smaller and lighter object when cleaning, mending, turning or otherwise processing the defective cylinder.

Besteht eine der Verbindungen aus einem Universalgelenk (Fig. 6), so hat die Einrichtung noch den Vorteil, daß die Lager des Zylinders nicht genau gerichtet zu sein brauchen, da das Universalgelenk eine ununterbrochene Drehung zuläßt, auch wenn die Mittellinien der Lager nicht genau gleichgerichtet sind, so daß nicht zu befürchten steht, daß ein Wellenbruch eintritt. If one of the connections consists of a universal joint (Fig. 6), the device has nor the advantage that the bearings of the cylinder do not have to be precisely aligned, since that Universal joint allows uninterrupted rotation even when the center lines of the bearings are not exactly in the same direction, so that there is no fear that a shaft break will occur.
