Abstract

Honeycomb expanded metal packing structures are produced from continuous perforated, drafted (expanded) metal strip. The three dimensional structure is generated by rolling together the perforated, expanded strip taken from two feed rolls on to a common core, after one of the feed rolls has been reversed by rewinding.

Description

Die Erfindung betrifft ein Verfahren entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of claim 1.

Bei der Herstellung von Streckmetall erhalten die Stege der wabenartigen Struktur eines Streckmetall-Bandmaterials stets eine bestimmte Neigung. Dabei bildet sich eine sog. neutrale Linie in Längsrichtung des Bandes aus, die etwa in der Mitte des Bandes liegt und auf deren beiden Seiten die Stege entgegengesetzt geneigt sind.In the production of expanded metal, the webs are given the honeycomb structure of an expanded metal strip material always has a certain inclination. This forms one so-called neutral line in the longitudinal direction of the tape, which is approximately in the middle of the tape lies and on both sides of the webs are inclined in opposite directions.

Stellt man nun aus solch einem Bandmaterial Füllkörper durch Wickeln her, dann kommen die wabenartigen Strukturen übereinanderliegender benachbarter Windun­ gen einer Rolle so zu liegen, daß sie ineinanderrutschen oder später beim Gebrauch durch Erschütterungen ineinanderrutschen können.If you now produce packing material from such a strip material by winding, then come the honeycomb structures of superimposed neighboring winds to lie against a roll so that they slide into each other or later in use can slip into one another due to vibrations.

Um eine Füllkörper mit einem bestimmten Solldurchmesser durch Wickeln herzu­ stellen, wird daher mehr Material benötigt, als aufgrund der Dicke der wabenartigen Struktur zu erwarten wäre.To create a packing with a certain nominal diameter by winding more material is needed than the thickness of the honeycomb Structure would be expected.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dem das Ineinanderrutschen der wabenartigen Strukturen von übereinanderliegenden be­ nachbarten Windungen beim Wickeln eines Füllkörpers verhindert wird.The object of the invention is therefore to create a method with which the slipping of the honeycomb-like structures of superimposed be neighboring turns when winding a packing is prevented.

Gelöst wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruchs angegebenen Merkmale.This problem is solved by the in the characterizing part of the patent claim specified characteristics.

Durch das Umspulen einer Vorratsrolle wird in einfacher Weise erreicht, daß die Längsränder des zu einer Vorratsrolle aufgewickelten Streckmetall-Bandmaterials bezüglich einer nicht umgespulten Rolle seitenverkehrt sind. Wickelt man nun zwei Rollen, nämlich eine umgespulte und eine nicht umgespulte, zusammen, dann haben die Stege der übereinanderliegenden, wabenartigen Strukturen benachbarter Win­ dungen eine entgegengesetzte Neigung und können nicht mehr ineinanderrutschen. Dadurch erreicht man bezüglich des Solldurchmessers von Füllkörpern eine Material­ ersparnis von etwa 15-20%.By rewinding a supply roll is achieved in a simple manner that Longitudinal edges of the expanded metal strip material wound into a supply roll  are reversed with regard to a role that has not been rewound. Now you wrap two Rolls, namely one rewound and one not rewound, then have the bridges of the superimposed, honeycomb structures of neighboring Win opposite slope and can no longer slide into each other. In this way, a material is achieved with respect to the nominal diameter of the packing savings of about 15-20%.

Das Verfahren ist selbstverständlich auch anwendbar, wenn es gelingt, das Quer­ strecken des Ausgangsmaterials zur Bildung des Streckmetalls ohne Bildung der neu­ tralen Linie durchzuführen, wenn also alle Stege dieselbe Neigung haben.The procedure can of course also be used if the cross succeeds stretch the starting material to form the expanded metal without forming the new tral line, so if all webs have the same inclination.

Die Erfindung wird nachstehend anhand der Fig. 1 und 2 beispielsweise erläutert, die schematisch die Durchführung des erfindungsgemäßen Verfahrens zeigen.The invention is explained below with reference to FIGS. 1 and 2, for example, which show schematically the implementation of the inventive method.

Fig. 1 zeigt eine Vorratsrolle 11, die aus aufgewickelten Streckmetall-Bandmaterial besteht, das von einer Schneid- und Streckmaschine geliefert wird. Dieses Band­ material 13 wird zu einer Vorratsrolle 12 umgespult. Fig. 1 shows a supply roll 11 , which consists of wound expanded metal strip material, which is supplied by a cutting and stretching machine. This tape material 13 is rewound into a supply roll 12 .

Wie Fig. 2 zeigt, verwendet man nun eine nichtumgespulte Vorratsrolle 11 und eine umgespulte Vorratsrolle 12 und wickelt sie über Umlenkrollen 15 zu einer Rolle 14, die unmittelbar einen Füllkörper bilden oder als Vorratsrolle zur Herstellung von Füll­ körpern dienen kann.As shown in Fig. 2, one now uses a non-rewound supply roll 11 and a rewound supply roll 12 and winds them over deflection rolls 15 to form a roll 14 which can directly form a filler or can serve as a supply roll for the production of fillers.
