Description

Im Patent 862 32i ist eine Vorrichtung beschrieben, mit der man aus einem Metallband einen Mast od..dgl. wickeln kann, der sich nach Bedarf wieder auf eine Rolle zurückwickelh läßt. Um die Bewegungen des Metallbandes durchzuführen, kann man sich der für derartige Vorgänge bekannten Einrichtungen bedienen, indem man das Metallband beispielsweise mit Perforationen versieht oder über Zug- bzw. Schubwalzen laufen läßt, die gegebenenfalls mit einem Reibbelag versehen sind. In der Praxis befriedigen diese Anordnungen für die hier in Betracht kommenden Zwecke nicht. Bei Bändern mit Perforationen ergeben sich leicht Beschädigungen des Bandes durch Aufreißen der Durchlochungen,während die Zug- walzen od. dgl. durch Einwirkung von Feuchtigkeit, Staub, Sand, Eisbildung usw. unliebsame Störungen erfahren.In the patent 862 32i a device is described with which a mast od .. the like from a metal strip. which can be wound back onto a roll as required. In order to carry out the movements of the metal strip, one can use the devices known for such processes, for example by providing the metal strip with perforations or by running it over pulling or pushing rollers, which are optionally provided with a friction lining. In practice, these arrangements are unsatisfactory for the purposes under consideration here. In the case of tapes with perforations, the tape is easily damaged by tearing open the perforations, while the pulling rollers or the like experience undesirable disturbances due to the action of moisture, dust, sand, ice formation, etc.

Durch die Erfindung werden diese Schwierigkeiten beseitigt, und zwar derart, daß zusammen mit dem Vorratsband, aus dem der Mast od, dgl. gewickelt werden soll, ein Zugband aufgewickelt ist, das über .die unterste Windung des Mastes laufend mit einer zweiten Trommel verbunden ist. Indem man bei einer solchen Anordnung das Zugband, das in einer Schlinge um den Anfang des zu: wickelnden Mastes läuft, von der Vorratsrolle auf eine Abnahmerolle spult, wird das Metallband zwangläufig mitgenommen und zu einem Rohr gedreht.The invention overcomes these difficulties, namely such that together with the supply tape from which the mast od, the like. Are wound should, a drawstring is wound up, which runs over the lowest turn of the mast is connected to a second drum. By using the Drawstring that runs in a loop around the beginning of the mast to be wound from the supply roll spools onto a take-off roll, the metal strip is inevitably taken along and turned into a pipe.

Das Zugband kann ebenfalls aus Metall oder auch aus Gummi oder einem anderen Werkstoff bestehen. Man wird es im allgemeinen mit einem flachen Querschnitt versehen, wenngleich auch andere Formen denkbar wären. In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel schaubildlich dargestellt. Mit i ist die Vorratsrolle bezeichnet, auf welche das für die Bildung des Mastes erforderliche Metallband 2 zusammen mit dem Zugband 3 aufgespult ist. Das Zugband läuft in einer Schlinge um die erste Windung des zu bildenden Mastes herum zu einer Spule q., auf die es mit Hilfe eines Kegelradgetriebes od. dgl. aufgeliickelt werden kann. Indem man mittels dieses Getriebes das Band 3 von der Rollei abzieht, wird gleichzeitig das Metallband 2 mit bewegt und zu einem Rohr gewickelt, das sich durch entgegengesetzte Rückspulung .der Bänder 2 und 3 wieder einfahren läßt.The drawstring can also be made of metal or rubber or a other material exist. It will generally be made with a flat cross-section provided, although other shapes would also be conceivable. In the drawing is the Invention shown diagrammatically using an exemplary embodiment. With i is the Supply roll denotes on which the necessary for the formation of the mast Metal band 2 is wound up together with the tension band 3. The drawstring runs in one Loop around the first turn of the mast to be formed into a coil q which it od with the help of a bevel gear. Like. Can be wound up. By doing if you pull the tape 3 from the Rollei by means of this gear, it will be simultaneously the metal band 2 moved with and wound into a tube that passes through opposite Rewinding .the tapes 2 and 3 retract again.

Obgleich die Erfindung in erster Linie für die Herstellung von Schraubbandmasten bestimmt ist, wäre es doch auch möglich, sie auch bei anderen Gelegenheiten zu verwenden, bei denen es sich darum handelt, durch die Bewegung des Zugbandes Dreh- oder Wickelbewegungen hervorzurufen. Im übrigen könnten an Stelle des in der Zeichnung dargestellten einzigen Zugbandes auch mehrere solcher Bänder gleichzeitig Verwendung finden.Although the invention is primarily for the manufacture of screw tape masts is determined, it would also be possible to use it on other occasions as well, which are rotating or winding movements due to the movement of the drawstring to evoke. In addition, instead of the only one shown in the drawing Several such straps can also be used at the same time as the drawstring.
