Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der Erfindung ist ein gedrehtes oder geflochtenes Seil zur Herstellung von Schrämen in Bergwerken, das sich dadurch von dem in der Patentschrift 181985 gekennzeichneten Seil unterscheidet, daß nicht das aus mehreren unter sich verseilten Schneiddrähten bestehende Schneidseil um das Kernseil gewunden ist, sondern daß die einzelnen Seilstränge des Kernseiles von solchen verseilten Schneiddrähten umgeben sind, ähnlich wie dies durch die Patentschrift 179779 bei Verwendung einzelner Drähte bekannt geworden ist.The invention relates to a twisted or braided rope for the production of Schrämen in mines, which is characterized by that in the patent 181985 The difference between rope is that it does not consist of several cutting wires twisted together existing cutting rope is wound around the core rope, but that the individual strands of the core rope stranded by such Cutting wires are surrounded, similar to that shown in patent 179779 Use of single wires has become known.

Die Vorteile des so gebildeten Schrämseiles bestehen darin, daß die verseilten Schneiddrähte gegenüber der im Hauptpatente getroffenen Anordnung dünner gewählt werden können; auch kann die Anzahl der Drähte geringer sein, da sie im Grunde, wo sich die Seilstränge gegen die Schneiddrähte legen, gestützt und in ihrer Lage gehalten werden. Hierdurch wird eine Verschiebung der Schneiddrähte auf dem Kernseil verhindert und die· Seile können über Seilscheiben von verhältnismäßig geringem Durchmesser laufen, da die so verseilten und gehaltenen schwächeren und aus einer geringeren Anzahl bestehenden Schneiddrähte genügend nachgiebig sind.'The advantages of the cutting cable formed in this way are that the stranded cutting wires can be chosen thinner compared to the arrangement made in the main patent; also can be the number of wires be lower because they are basically where the rope strands lie against the cutting wires, supported and held in place. This causes a shift in the cutting wires prevented on the core rope and the ropes can over pulleys of relatively small diameter, because the stranded and held in this way are weaker and consist of a smaller number Cutting wires are sufficiently flexible. '

Das Schrämseil ist auf der Zeichnung veranschaulicht. The cutting rope is illustrated in the drawing.
