Um die um die Seele des Stahlcordes geschlagene Außenlitze herzustellen, müssen mehrere Drähte oder verdrillte Litzen fc mittels einer Drillmaschine um eine Seele der Außenlitze ge· schlagen werden. Die auf diese Weise gebildeten Außenlitzen müssen dann von einer anderen Drillmaschine um die Seele des Stahlcordes geschlagen werden. Palis die Außenlitzen des Stahlcordes aus mehreren verdrillten Litzen bestehen, 1st eine weitere Drillmaschine erforderlich, um aus den "verdrillten Litzen die Außenlitze zu bilden.In order to produce the outer strand wrapped around the core of the steel cord, several wires or twisted strands are required fc around a core of the outer strand by means of a seed drill will beat. The outer strands formed in this way then have to be wrapped around the core of the Steel cords are beaten. Palis the outer strands of the If steel cords are made up of several twisted strands, an additional seed drill is required to remove the "twisted" strands Strands to form the outer strand.
Zur Herstellung eines solchen Stahlcordes ist somit eine größere Anzahl von Yerfahrensschritten erforderlich, was hohe Herstellungskosten und einen erheblichen Zeitaufwand zur Folge hat. Der den Stahlcord enthaltende Gummiteil (Fahrzeugreifen und ReifengUrtel) wird entsprechend teuer.To produce such a steel cord, a larger number of process steps is required, which high manufacturing costs and a considerable amount of time result. The rubber part containing the steel cord (Vehicle tires and tire belts) is correspondingly expensive.
Durch die Erfindung sollen diese Nachteile vermieden werden. Insbesondere liegt der Erfindung die Aufgabe zugrunde, einen Stahlcord zu schaffen, der sich wirtschaftlicher herstellen läßt und dennoch bessere mechanische Eigenschaften (aum Ballspiel Bruchfestigkeit und "jlastisitätsmodul) als derThe invention is intended to avoid these disadvantages. In particular, the invention is based on the object of creating a steel cord which can be produced more economically and still has better mechanical properties (aum ball game Breaking strength and "elasticity modulus") than the
209812/0627209812/0627
bekannte Stahlcord hat. Dies wird bei einem Stahlcord mit einer mehrere Adern aufweisenden Seele und mehreren um die Seele geschlagenen Außenlitzen erfindungsgemäß dadurch erreicht, daß die Adern der Seele derart parallel zueinander angeordnet sind, daß sie eine unverdrillte Litze bilden. Die Adern der Seele können entweder jeweils aus einem einzelnen Draht oder einer verdrillten Litze bestehen.well-known steel cord has. This is done with a steel cord a core having several cores and several outer strands wrapped around the core according to the invention achieved in that the cores of the core are so parallel to one another are arranged so that they form an untwisted strand. The cores of the core can either consist of a single wire or a twisted strand.
Da die Seele des Stahlcordes die Form einer parallel verlaufenden, unverdrillten Litze hat, ist zur Herstellung der Seele keine Drillmaschine erforderlich, wodurch die Herstellungskosten der Seele wesentlich verringert werden. Ferner hat die Seele des erfindungsgemäßen Stahlcordes einen geringeren Verlust an Bruchfestigkeit sowie einen größeren Elastizitätsmodul, wodurch die Bruchfestigkeit und die · Dauerfestigkeit erhöht werden.Since the core of the steel cord has the shape of a parallel, untwisted strand, the Soul no seed drill required, which significantly reduces the manufacturing costs of the soul. Furthermore, the core of the steel cord according to the invention has a lower loss of breaking strength and a greater loss Modulus of elasticity, which increases the breaking strength and fatigue strength.
Jede der Außenlitzen kann aus einem Draht oder einer verdrillten Litze bestehen. Die verdrillte Litze, die die entsprechende Außenlitze bildet, kann ferner aus mehreren Drähten oder wiederum aus mehreren verdrillten Litzen bestehen.Each of the outer strands can consist of a wire or a twisted strand. The twisted strand that forms the corresponding outer strand can also consist of several wires or, in turn, of several twisted strands.
den fertigen Stahlcord kann eine Bindeleine geschlungen werden, die das Lösen des Stahlcordes verhindern soll·The finished steel cord can be looped into a binding line to prevent the steel cord from loosening
