Embodiment Construction

[0036] Referring first to Figures 1, 1A and 2, a machine assembly 10 for building a tire on a core assembly 11 is shown. The core assembly 11 is generally annular and the tire is formed thereon by sequentially laminating the tire components on the annular core. A platform 12 may be provided as a support for the assembly 10 . A drive motor 14 is connected by conventional shafts to rotate the core assembly 11 as the layers of tire components are sequentially applied to the annular core.

[0037] The above figures show four arm assemblies 16A-D arranged around the core assembly in a preferred arrangement. Although four components are included in this device embodiment 10, the invention is not intended to be so limited. A single arm assembly could also be used if desired. Alternatively, more or less than four components can also make up the device if desired. The four arm assemblies 16A-D are arranged at preferred intervals around the core assembly 10, which allows the arm ass...

Abstract

A cord ply construction for a tire is provided formed by a series of spaced single line cord paths, each extending along a path from an originating side of the tire across the crown region to an opposite terminal tire side, the cord paths each creating a loop at the terminal tire side and returning to the originating side and wherein the series of spaced single line cord paths combine to form a completed cord ply layer. Each cord path forms a cord angle that changes in magnitude from the originating side to the terminal tire side, the cord angle being at a highest magnitude at a tire tread centerline and decreasing toward the originating tire side.

Description

technical field [0001] [001] The present invention relates generally to tire ply cord construction and, more particularly, to a tire having at least one ply formed from split end cords applied in a gauge cord construction. Background technique [0002] [002] Pneumatic tires have traditionally been manufactured as a generally annular layered structure having a bead, tread, belt reinforcement, and carcass. Tires consist of rubber, fiber and steel cords. Most applied manufacturing processes involve assembling various tire components from flat strips or layers of material. Each part is placed on the forming drum and cut to length as required so that the ends of the parts meet or overlap to form a joint. [0003] [003] The first stage of assembling a prior art carcass typically involves assembling one or more plies and a pair of sidewalls, a pair of apexes, an inner liner (for a tubeless tire), a pair of chafers and possibly There is also a pair of rubber tire shoulder straps....
