发明名称 Method of manufacturing a reinforced tubular component of a motor vehicle tire carcass.
摘要 <p>A method of manufacturing a reinforced component of a motor vehicle tire carcass, in particular, a tubular toroidal body ply (12)(20)(24)(25) extending about and encapsulating two annular lateral beads (8), whereby the two annular beads (8) are arranged coaxially and separated by a first distance (A)(C)(D) greater than a final distance (B), so as to define, at least partially, a toroidal frame (11)(21)(26) about which an elongated reinforcing element (13) is wound to form a semifinished tubular body ply (12)(20)(24)(25) encapsulating the beads (8); the semifinished tubular body ply (12)(20)(24)(25) then being shaped radially by at least bringing the beads (8) together to within the final distance (B), so as to form the semifinished tubular body ply (12)(20)(24)(25) into a finished tubular body ply (1) having a substantially U-shaped cross section. &lt;IMAGE&gt; &lt;IMAGE&gt;</p>
