METHOD AND APPARATUS FOR BUILDING A CORD WOUND CLOSED TORUS CARCASS Abstract of the Disclosure Method and apparatus for wrapping a cord or wire in a toroidal helix about a liner to form a closed torus carcass. An extruder, die, and diehead provide means for extruding a liner having a horseshoe-shaped profile. Circumferential edges of the liner are joined with a pre- formed assembly of bead rings and a spacer ring. Cord or wire is wound snugly about an array of control fingers and then slipped off the fingers as successive tensionless turns about the liner and rings as the latter rotate through a winding plane in which a spool supplying cord or wire orbits. No rigid core is required. An endless inflatable tube can be used in lieu of the extruder liner. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
