Abstract
A reinforcement for rubber is disclosed, which comprises a cord made from an amorphous iron-base alloy filament previously subjected to a wire drawing at a reduction of area of not less than 10%.
Claims8
A reinforcement for rubber comprising a cord obtained by subjecting an amorphous iron-base alloy filament, which is produced by jet spinning molten metal into a refrigerant carrier, to a wire drawing at a reduction of area of not less than 10% and then twisting a plurality of resulting drawn filaments as a cord stock.
A method of manufacturing a reinforcement for an elastomeric cord comprising the steps of:
- producing an amorphous iron-base alloy filament by jet spinning molten metal into a refrigerant,
- drawing said filament into a wire at a reduction of area of at least 10% and,
- twisting a plurality of drawn wires into a cord stock.
