Abstract
Abstract Pneumatic tires and like mold-cured cord reinforced elastomeric articles are rendered less susceptible to blow or blister defects by combining with the continuous filament strength cord auxiliary gas receiving voids provided by a small yarn of staple fiber thereby increasing the total voids volume and enabling contained air or gas to be safely retained within the tire or article. 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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
A pneumatic tire having a plurality of reinforcing cords comprising yarns of continuous filaments and stable fibers plied together, the yarn of staple fibers being not more than 35 percent by weight of the total weight of said cords, each of said cords having voids for receiving compressible gases within thE tire, the volume of the voids being at least 10 percent of the gross volume occupied by the continuous filaments and staple fibers of the cords.
Claim 2
Dependent Claim
77 words
A pneumatic tire having a plurality of reinforcing cords comprising yarns of continuous filaments and stable fibers plied together, the yarn of staple fibers being not more than 35 percent by weight of the total weight of said cords, each of said cords having voids for receiving compressible gases within thE tire, the volume of the voids being at least 10 percent of the gross volume occupied by the continuous filaments and staple fibers of the cords.
Claim 3
Dependent Claim
12 words
The pneumatic tire of claim 1, wherein the staple fibers are cellulosic.
Claim 4
Dependent Claim
12 words
The pneumatic tire of claim 1, wherein the continuous filaments are thermoplastic.
Claim 5
Dependent Claim
12 words
The pneumatic tire of claim 3, wherein the continuous filaments are polyester.
Claim 6
Dependent Claim
30 words
The pneumatic tire of claim 1, wherein the staple fibers are cotton fibers comprising from about 9 to about 15 percent by weight of the total weight of said cords.
Claim 7
Dependent Claim
12 words
The pneumatic tire of claim 5, wherein the continuous filaments are polyester.
Claim 8
Dependent Claim
88 words
A cord used with a plurality of other similar cords for reinforcing a pneumatic tire to reduce the incidence of blow or blister defects therein, comprising a multiplicity of continuous filaments and at least one yarn of staple fiber which is not more than 35 percent by weight of the total weight of said cord, said cord having voids for receiving compressible gases within a tire, the volume of the voids being at least 10 percent of the gross volume occupied by the continuous filaments and staple fibers.
Claim 9
Dependent Claim
88 words
A cord used with a plurality of other similar cords for reinforcing a pneumatic tire to reduce the incidence of blow or blister defects therein, comprising a multiplicity of continuous filaments and at least one yarn of staple fiber which is not more than 35 percent by weight of the total weight of said cord, said cord having voids for receiving compressible gases within a tire, the volume of the voids being at least 10 percent of the gross volume occupied by the continuous filaments and staple fibers.
Claim 10
Dependent Claim
12 words
The cord of claim 7, wherein the staple fiber is cellulosic material.
Claim 11
Dependent Claim
11 words
The cord of claim 7, wherein the continuous filaments are thermoplastic.
Claim 12
Dependent Claim
11 words
The cord of claim 9, wherein the continuous filaments are polyester.
Claim 13
Dependent Claim
28 words
The cord of claim 7, wherein the staple fiber is cotton comprising from about 9 to about 15 percent by weight of the total weight of said cord.
Claim 14
Dependent Claim
11 words
The cord of claim 11, wherein the continuous filaments are polyester.
Claim 15
Independent Claim
109 words
The method of reducing the incidence of blow or blister defects in pneumatic tires having reinforcement plies including cords comprising a plurality of yarns of continuous thermoplastic filaments, said method comprising: twisting together individually with cords of at least one of said reinforcement plies of yarn of staple cellulosic fiber, said yarn being not more than 35 percent by weight of said cord including said yarn; placing said ply within the body of a tire while building said tire; applying pressure onto the surfaces of said tire to compel gas contained within said tire to move into interfilamentary and interfiber spaces within said cord; and then curing said tire.
Claim 16
Independent Claim
109 words
The method of reducing the incidence of blow or blister defects in pneumatic tires having reinforcement plies including cords comprising a plurality of yarns of continuous thermoplastic filaments, said method comprising: twisting together individually with cords of at least one of said reinforcement plies of yarn of staple cellulosic fiber, said yarn being not more than 35 percent by weight of said cord including said yarn; placing said ply within the body of a tire while building said tire; applying pressure onto the surfaces of said tire to compel gas contained within said tire to move into interfilamentary and interfiber spaces within said cord; and then curing said tire.
