Abstract
216,319. Beyea F. H. May 10, 1923. Wire cores, covering by winding.-An endless bead wire for pneumatic tyres &c. is formed of a circular core wire 1 upon which is wound a crimped wire 3. The wire 3, previously formed into a helix, is unwound from a spool 4, and is laid on the core without longitudinal torsion by passing the spool therearound while maintaining its axis at a constant angle to the plane of the circular core Alternatively, the wire 1 may be omitted, the first convolution of the helically formed covering wire acting as a core for the other convolutions. At the termination of the covering operation the adjacent ends of the wire 3 are joined together and to the core by soldering, the ends of the core having been welded or soldered together. In lieu of, or in addition to the solder, a clip may be used. The bead is then stretched to the proper size to cause the wires to lie smoothly over the surface.
