In this case, they are provided on the outer circumference with a radius R which corresponds approximately to half the rope diameter, in order, together with the wire strands 15, to form an approximately uniform outer diameter.
- R which corresponds approximately to half the rope diameter
- Such wire ropes 10 are used in particular as traction or conveyor ropes with high load requirements, for example in cable cars which are suspended from a stationary support rope and connected to a traction rope.
- Pulling or conveying ropes are usually guided around pulleys at the upper and lower stations and designed as endless ropes by splicing their ends or held together by an end attachment, which is not shown in detail.
- the stranded wire strands 15 rest over a certain circumferential area in the grooves 20 directly on the plastic core 11, while the inserts 12 are each arranged on the inside at a distance a from the plastic core 11.

Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung sowie auf ein Drahtseil nach dem Oberbegriff des Anspruchs 1 bzw. 6, sowie eine Einrichtung nach dem Oberbegriff des Anspruchs 12.The invention relates to a method for production and to a wire rope according to the preamble of claim 1 or 6, and a device according to the preamble of
Bei einem Drahtseil gemäss der Druckschrift
Bei diesem zylindrisch ausgebildeten Kern bildet sich im Betrieb des Drahtseils in der Regel nach einer gewissen Anfangsbetriebszeit ein Fliessen in radialer Richtung nach aussen, wodurch den Aussenkonturen der Drahtlitzen angepasste Nuten am Umfang des Kerns entstehen. Damit sind aber verschiedene Nachteile verbunden, insbesondere entsteht ein Kriechen und damit eine Verlängerung des gesamten Drahtseils im Betrieb, welche wieder kompensiert werden muss. Zudem ändert sich auch der Seildurchmesser im Betrieb, was bei der Installation derselben zu berücksichtigen ist.With this cylindrically designed core, when the wire rope is in operation, after a certain initial operating time, a flow in the radial direction outwards forms, as a result of which grooves adapted to the outer contours of the wire strands are created on the circumference of the core. However, this is associated with various disadvantages, in particular creeping and thus an extension of the entire wire rope occurs Operation, which must be compensated again. In addition, the rope diameter also changes during operation, which must be taken into account when installing the same.

Solche Drahtseile 10 werden insbesondere als Zug- bzw. Förderseile mit hohen Belastungsanforderungen verwendet, beispielsweise bei Seilbahnen, welche an einem stationären Tragseil hängend geführt und mit einem Zugseil verbunden sind. Zug- bzw. Förderseile werden üblicherweise bei der oberen und unteren Station um Rollen geführt und als Endlos-Seile durch eine sogenannte Verspleissung von deren Enden ausgeführt oder durch eine Endbefestigung zusammengehalten, was nicht näher gezeigt ist.
