Abstract
Abstract A method of providing a direct and very short venting path for the cord plies normally built into the carcass of a pneumatic vehicle tire, comprising applying a net of cord onto the inner surface of a camel-back strip while still in hot, plastic condition, projecting circumferentially spaced strands of said net through the thickness of the tread layer, and finally applying the composite tread and net onto the buffed worn surface of the tire in a manner so that certain strands of the net contact the ply layers of cord of the tire carcass.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
A tire construction comprising a carcass having ply layers of cord, a tread strip including on its inner surface a net of cord extending about the entire periphery of the tire and in contacting relationship with at least one of said ply layers, a plurality of strands of said net extending in circumferentially spaced relationship through the entire thickness of the said tread strip so as to provide a short and direct venting path from said ply layers and said net of cord to the outside surface of said tread layer so as to prevent separation of the tread layer from said carcass.
Claim 2
Dependent Claim
103 words
A tire construction comprising a carcass having ply layers of cord, a tread strip including on its inner surface a net of cord extending about the entire periphery of the tire and in contacting relationship with at least one of said ply layers, a plurality of strands of said net extending in circumferentially spaced relationship through the entire thickness of the said tread strip so as to provide a short and direct venting path from said ply layers and said net of cord to the outside surface of said tread layer so as to prevent separation of the tread layer from said carcass.
Claim 3
Dependent Claim
34 words
A tire construction as recited in claim 1 wherein said net includes a central, circumferentially extending strand which is stretchable sufficiently to enable projection of the strands through the entire thickness of the tread.
Claim 4
Dependent Claim
56 words
A tire construction as recited in claim 1, wherein said tread is made of up of thin strands of rubber spirally wound about the circumference of the tire in side-by-side relationship and wherein cord layers of said net are sandwiched between certain of said thin strands of rubber to provide multiple air-venting paths through said tread.
Claim 5
Dependent Claim
102 words
A tire construction comprising a carcass having ply layers of cord and a tread rubber layer, a net of cord between said tread rubber layer and carcass, said net being connected to certain of the cords of said ply layers of cord so as to provide an air ventilating path therebetween, and a plurality of air-venting cords extending throughout the entire thickness of said tread rubber layer and being transversely and circumferentially spaced from one another and connected to said net so as to provide a multiplicity of air-venting paths from said net to the outer surface of said tread rubber layer.
Claim 6
Dependent Claim
102 words
A tire construction comprising a carcass having ply layers of cord and a tread rubber layer, a net of cord between said tread rubber layer and carcass, said net being connected to certain of the cords of said ply layers of cord so as to provide an air ventilating path therebetween, and a plurality of air-venting cords extending throughout the entire thickness of said tread rubber layer and being transversely and circumferentially spaced from one another and connected to said net so as to provide a multiplicity of air-venting paths from said net to the outer surface of said tread rubber layer.
Claim 7
Dependent Claim
62 words
A tire construction as recited in claim 4 wherein said net of cord comprises a plurality of spaced, parallel multifilar strands surrounding the periphery of the tire, and a sinuously wound strand extending transversely thereof and passing through said multifilar strands and frictionally held thereby, portions of said sinuously wound strands extending alongside the outer portion of said peripherally spaced multifilar strands.
Claim 8
Dependent Claim
30 words
A tire construction as recited in claim 5 wherein said outer portions of said sinuously wound strands are cut and project outside the tire sidewalls to provide venting terminals thereat.
