ABSTRACT:
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 preformed 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 extruded liner.
