<p>A breaker reinforcing tape for belted pneumatic tires, a method of making such tape, and a method or constructing such tires therewith, are disclosed. The tape includes a generally sinusoidally crimped strip of uncured rubber and a plurality of similarly crimped parallel cords having their undulations following and nesting in the undulations of the crimped strip, the cords at successive apexes being secured to successive apexes of the strip. A second uncured rubber strip in a flat condition is secured to alternate ones of the apexes of the undulations of the array of cords and the crimped strip at one race of the latter. At least one frangible element is interposed in a fixed and substantially flat condition between the crimped and flat strips fro releasably reinforcing and stabilizing the flat strip against inadvertent expansion that would prematurely reduce the amplitude and frequency of the undulations of the crimped strip and its associated cords. The tape, when used in making a tire, is wound helically about the crown region of the carcass, outwardly of the breaker plies, at an angle of substantially zero degrees to the mid circumferential plane or the carcass. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.</p> |
