THIN GAUGE, FINE DIAMETER STEEL CORD REINFORCED TIRE PLY FABRIC AND A METHOD OF LAP SPLICING THE FABRIC

A thin gauge, fine diameter steel cord reinforced tire ply fabric 2 is disclosed which can be effectively lap spliced without detrimental effect. The steel cord 1 has one or more filaments 9, each filament has a percent elongation of over 2.5% and tensile strength of at least (-2000D+4400 MPa) .time...

Beschreibung
Zusammenfassung:	A thin gauge, fine diameter steel cord reinforced tire ply fabric 2 is disclosed which can be effectively lap spliced without detrimental effect. The steel cord 1 has one or more filaments 9, each filament has a percent elongation of over 2.5% and tensile strength of at least (-2000D+4400 MPa) .times. 95%, where D is the diameter of the filament in millimeters. For passenger and lightly loaded trucks the fabric 2 is manufactured using a preferred cord 1 which is a 1+5.times..18 mm wire spaced 14 ends per inch, for heavier loaded vehicles such as light trucks load rated E or greater the number of cords 1 is increased to 28 ends per inch. The fabric 2 used as a single radial ply for a pneumatic tire 20 can be spliced using a lap splice technique due to the strength and fineness of the cord 1 in combination with the very thin gauge g between the adjoining surfaces 10.
