Reinforced tire fabric of helically formed,laterally spaced,single filament wires
Abstract
Abstract A reinforced tire fabric comprising an elastomeric body portion in which a plurality of helically formed. single filament wires constitute the reinforcing. The helix delineated by each reinforcing wire has a relatively long lay and the diameter thereof is preferably no greater than three times the diameter of the wire itself. The wire filaments may be cold formed into their respective helices by being drawn though relatively being opposite hand-and encapsulated into a continuously extruded ribbon that is manipulated and appropriately severed to form the fabric. The ribbon may be wound into an annulus that is subsequently slit into a ply strip, or successive lengths of the ribbon may be joined into a ply strip. By either approach the bias of the reinforcing filaments in the finished tire may be preselected.
