Tube having an armoring consisting of a plurality of wires

摘要

In the case of strand-shaped material, for instance corrugated tubes, electric cables or lines, there is provided on the surface of the material an armoring comprising a plurality of wires which are applied with a long length of lay and are held by a further armoring layer. The wires are applied to the material with changing direction of lay. The additional armoring layer is at least one wire applied with a short length of lay and which is applied with initial tension onto the first armoring layer.
