Description

Schab oder Messerkopf zum Kalibrieren und Glätten der Verschlußöffnungen von Papierflaschen Die Erfindung bezieht-sich auf Papierstoffflaschen und -behälte@, die durch zylindrisches Wickeln von Papierbahnen unter gleichzeitiger Einführung eines Binde- bzw. Imprägniermittels hergestellt werden und unter Anwendung von Druck und Wärme 'ihre endgültige Form erhalten. Die zu verschließende Öffnung solcher Papierstoffbehälter oder =Haschen muß zur Aufnahme von dichten, -insbesondere öldichten Verschlußkap'seln glatt und genau kali.briert sein. Es hat sich nun gezeigt, daß bei der Formung der Flaschen unter Druck und Wärme an der öffnung steinharte Bärte sich bilden, die das Glätten und Kalibrieren außerordentlich erschweren. Zur Beseitigung dieser steinharten Bärte haben sich der Verschlußöffnung angepaßte Schab- oder Messerköpfe aus Stahl oder Carborundum als völlig ungeeignet erwiesen. Es hat sich nun überraschenderweise herausgestellt, daß Schab- oder Messerköpfe aus Stahl sich nur wenig abnutzen, wenn man sie bis zur Rotglut erhitzt und mit verhältnismäßig hohen Umdrehungszahlen auf den Flaschen- oder Behälterhals einwirken läßt. Die von einem solchen Werkzeug ausgeübte Wirkung besteht in der Hauptsache- in einem Absengen der vorstehenden Grate oder Bärte. Die hohe Umdrehungszahl verhindert dabei ein eigentliches Brennen. Die Wirkung ist als eine kombinierte anzusehen, indem die hohe Wärme (Rotglut) des Werkzeugs zunächst die Gratteile, mit denen das Werkzeug beim Vorschub zuerst in Berührung kommt, sengt (verkohlt), worauf dann die angekohlten oder angesengten Teile unter Einwirkung der hohen Umdrehungsgeschwindigkeit abgeschert werden. Dabei hat es sich .als'vorteilhaft herausgestellt, die versengten und albgescherten Teile sofort abzusaugen, um jede Brennmöglichkeit zu unterbinden.Scraper or knife head for calibrating and smoothing the closure openings of paper bottles Maintain shape. The opening to be closed of such paper stock containers or hashes must be smooth and precisely calibrated to accommodate tight, especially oil-tight caps. It has now been shown that when the bottles are formed under pressure and heat, stone-hard beards form on the opening, which make smoothing and calibration extremely difficult. Scraper or cutter heads made of steel or carborundum which are adapted to the opening of the closure have proven to be completely unsuitable for removing these rock hard beards. It has now been found, surprisingly, that scraper or cutter heads made of steel wear only little if they are heated to red heat and allowed to act on the neck of the bottle or container at relatively high speeds. The main effect of such a tool is to singe the protruding burrs or beards. The high number of revolutions prevents actual burning. The effect is to be seen as a combined one, in that the high heat (red heat) of the tool first sings (carbonizes) the burr parts with which the tool first comes into contact during feed, whereupon the charred or seared parts shear off under the action of the high speed of rotation will. It has turned out to be advantageous to vacuum the scorched and sheared parts immediately in order to prevent any possibility of burning.

Ein Schab- oder Messerkopf nach der Erfindung besteht zweckmäßig aus einem äußeren Ringkörper, einer inneren Nabe und zwi= scheu beiden sich erstreckenden Schab- oder Messerstegen. Die dabei gebildeten Zwischenräume zwischen den Messern werden zweckmäßig unter Saugeinwirkung gehalten.A scraper or cutter head according to the invention is expediently made of an outer ring body, an inner hub and between two shyly extending ones Scraper or knife bars. The gaps formed between the knives are expediently kept under suction.

Ein Ausführungsbeispiel eines solchen Werkzeugs ist schematisch in Abb. i im Grundriß und in Abb. a in einer Stirnansicht auf die mit der zu glättenden und zu kalibrierenden Behälterwandung in Berührung kommende Fläche dargestellt.An embodiment of such a tool is shown schematically in FIG Fig. I in plan and in Fig. A in a front view of the one to be smoothed and the surface coming into contact with the container wall to be calibrated is shown.

In Abb. i ist der Schab- oder Messerkopf a und der Flaschenhals f im waagerechten Querschnitt dargestellt. Der Kopf a sitzt am Ende einer Welle c, die in nicht dargestellten Lagern ruht und mit hoher Geschwindigkeit umläuft. Von beiden Seiten wirken auf den Werkzeugkopf a Stichflammen von Gasbrennern b ein, die ihn während der Drehung in Rotglut erhalten.In Fig. I, the scraper or knife head a and the bottle neck f are shown in horizontal cross-section. The head a sits at the end of a shaft c, which rests in bearings (not shown) and rotates at high speed. Flashing flames from gas burners b act on the tool head a from both sides and keep it glowing red while it is rotating.

Der Schab- oder Messerkopf besteht zweckmäßig aus einzelnen Schabern oder Messern o. dgl. m, die gleichmäßig verteilt in einem Ringkanal h angeordnet sind -und sich radial zwischen dem äußeren Ring d und der inneren Nabe e erstrecken. Die Rückseite , des Werkzeugkopfes a ist von einer Kappe h umgeben, deren Innenraum! unter ständiger Einwirkung einer Saugpumpe steht.The scraper or cutter head expediently consists of individual scrapers or knives or the like, which are arranged evenly distributed in an annular channel h and extend radially between the outer ring d and the inner hub e. The back of the tool head a is surrounded by a cap h , the interior of which! is under the constant influence of a suction pump.

Die Schaber oder Messer nz können auch zur sicheren Wärmeübertragung aus breiten Stegen bestehen, insbesondere wenn die zu glättende und zu kalibrierende Öffnung des Papierstoffbehälters groß ist. Es ist aber wesentlich, daß das Abseng- und Abscherwerkzeug d ständig mit hoher Geschwindigkeit umläuft.The scraper or knife nz can also be used for safe heat transfer consist of wide webs, especially if the one to be smoothed and calibrated The opening of the paper stock container is large. However, it is essential that the and shearing tool d continuously rotates at high speed.

Der mit hoher Geschwindigkeit umlaufende Schab- oder Messerkopf wird durch Gasbrenner oder durch andere Heizmittel in Rotglut versetzt, ehe er mit dein zu kalibrierenden und zu -glättenden Flaschen- oder Behälterrand für einen kurzen Augenblick in Berührung kommt. Zu dem Zweck empfiehlt es sich, dem zu bearbeitenden Behälter/ eine schnelle Hinundherbewegung gegenüber dem Werkzeug a zu erteilen. -Es hat sich herausgestellt, daß keine merkbare Abnutzung des Schab- oder Messerkopfes a eintritt und der damit bearbeitete Behälter- oder Flaschenhals nicht nur genau kalibriert wird, sondern auch eine für Dichtungszwecke geeignete glatte Oberfläche erhält.The scraper or cutter head rotating at high speed is red heat caused by a gas burner or other heating means before he starts with your Bottle or container rim to be calibrated and smoothed for a short Moment comes into contact. For this purpose, it is advisable to use the Container / to give a quick reciprocation towards the tool a. -It has been found that there is no noticeable wear on the scraper or cutter head a occurs and the container or bottle neck processed with it not only precisely is calibrated, but also a smooth surface suitable for sealing purposes receives.
