Abstract
A longitudinal element produced with a core made of high-strength fibers and at least one metal casing, preferably steel, surrounding this core. In this way, there is the significant advantage that these high-strength fibers, which are very lightweight in relation to their strength, are protected in a number of ways, namely against humidity, moisture, UV light and other environmental influences. In addition, the metal casing provides the fibers with protection against transverse loads. In this way, all the high-strength properties of the traction or suspension means are maintained over a sustained period.
Claims21
A method for making a longitudinal element, comprising:
- providing high-strength fibers alongside one another to form a single cylindrical core of high-strength fibers having an outer diameter of 1.5 mm to 8 mm;
- providing a protective or load-bypassing filling layer, bandage or mixture thereof;
- providing a metal plate;
- and
- bending the metal plate around the single cylindrical core of high-strength fibers while the filling layer, bandage or mixture thereof is interposed between the metal plate and the single cylindrical core of high-strength fibers and then connecting abutting longitudinal edges of the metal plate to one another to form a metal casing around the filling layer, bandage or mixture thereof which in turn is around the single cylindrical core of high-strength fibers.
A method for making a longitudinal element, comprising:
- providing high-strength fibers alongside one another to form a single cylindrical core of high-strength fibers, the high-strength fibers of the single cylindrical core comprising steel fibers each having a tensile strength of more than 2,500 N/mm2;
- providing a protective or load-bypassing filling layer, bandage or mixture thereof;
- providing a metal plate;
- and
- bending the metal plate around the single cylindrical core of high-strength fibers while the filling layer, bandage or mixture thereof is interposed between the metal plate and the single cylindrical core of high-strength fibers and then connecting abutting longitudinal edges of the metal plate to one another to form a metal casing around the filling layer, bandage or mixture thereof which in turn is around the single cylindrical core of high-strength fibers.
