A steel cord particularly adapted for reinforcement of a protection ply in a tire has under compression in rubber a deformation W at instability of at least 3% and is stress-relieved so that its total elongation at rupture in rubber exceeds 3.5%. The steel cord comprises pearlite filaments.

Steel cord for protection plies of pneumatic tires

A steel cord adapted for the reinforcement of an elastomer comprises steel filaments of a pearlitic structure. The steel cord has a plastic and elastic elongation at break of x % and a plastic and elastic elongation capability in the vulcanized elastomer of y %, the values x and y fulfilling following equation:

Cord with high non-structural elongation

A steel strip (1) comprises two to seven round steel filaments (2) lying in parallel adjacent to one another so as to form a single plane of core filaments and one or more filaments (4) which are wrapped around the core filaments in one single wrapping direction. One or more core filaments, individually, or the plane of the core filaments as a whole have residual elastic torsions to such an extent that the strip remains substantially flat over the whole length of the strip if the strip is not subjected to external forces.

Steel strip and method of making

A process for the manufacture of hose or tubing conditions plastic high pressure hose having at least one reinforcing layer of steel wires, cords or longitudinal segments thereof. The hose is internally pressurized for a predetermined period of time which provides a residual permanent elongation of at least 0.5% and increases the interior volume by at least 2% upon release of the pressure.

Process for the manufacture of hose or tubing with a high resistance to

In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheral zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending-unbending operations in considerably different planes and simultaneously tensioning the cable.

Method of manufacturing fatigue resistant cables

In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheric zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending--unbending operations in considerably different planes and simultaneously tensioning the cable.
