Abstract

Abstract An endless reinforcement strip for a pneumatic tire which comprises continuous cord forming a generally zigzag pattern and being positioned across the width of the strip from one side to the other at an angle to the edges of the strip with reversals at the edges. Lengths of the cord between reversals are interleaved with lengths disposed at an opposite angle along at least one line substantially parallel to and intermediate the edges of the strip.

Claim 5
Dependent Claim 16 words
An endless reinforcement strip according to claim 1 wherein said strip includes more than one cord.
Claim 6
Dependent Claim 26 words
An endless reinforcement strip according to claim 1 wherein said strip has a distorted edge with cord reversals staggered with respect to other reversal points. Pg,15
Claim 7
Dependent Claim 23 words
An endless reinforcement strip according to claim 1 wherein the angle of the cord across the width of the strip changes between reversals.
Claim 8
Dependent Claim 27 words
An endless reinforcement strip according to claim 1 wherein continuous cord is disposed circumferentially of said strip and interleaved with the continuous cord forming the zigzag pattern.
Claim 9
Dependent Claim 18 words
An endless reinforcement strip according to claim 1 wherein the cord is associated with a green rubber belt.
Claim 10
Dependent Claim 26 words
An endless reinforcement strip according to claim 1 wherein rubber shoulder portions are disposed intermediate the edges of said strip and adjacent the edge portions thereof.
Claim 11
Independent Claim 142 words
A method of producing an endless reinforcement strip for a pneumatic tire which comprises covering continuous cord with rubber, winding said continuous cord in a generally zigzag pattern on a substantially cylindrical surface, positioning said cord across the entire width of said strip from one side to the other at an angle to the edges of said strip, reversing the cord adjacent each edge of said strip and interleaving lengths of said cord between reversals with lengths disposed at an opposite angle along at least one line substantially parallel to and intermediate the edges of said strip whereby each length of cord between reversals has portions disposed on both the inside and outside of said reinforcement strip, and said adjacent lengths of cord forming a plurality of triangular portions between said interleaving lines and lengths of cord disposed at said opposite angle.
Claim 12
Independent Claim 142 words
A method of producing an endless reinforcement strip for a pneumatic tire which comprises covering continuous cord with rubber, winding said continuous cord in a generally zigzag pattern on a substantially cylindrical surface, positioning said cord across the entire width of said strip from one side to the other at an angle to the edges of said strip, reversing the cord adjacent each edge of said strip and interleaving lengths of said cord between reversals with lengths disposed at an opposite angle along at least one line substantially parallel to and intermediate the edges of said strip whereby each length of cord between reversals has portions disposed on both the inside and outside of said reinforcement strip, and said adjacent lengths of cord forming a plurality of triangular portions between said interleaving lines and lengths of cord disposed at said opposite angle.
Claim 13
Dependent Claim 36 words
A method according to claim 10 wherein said lengths of cord are interleaved between reversals to provide alternate portions disposed on the outside and inside of said strip with at least two portions on each side.
Claim 14
Dependent Claim 30 words
A method according to claim 10 wherein between about 2 and 250 portions of said lengths of cord are disposed on each of the outside and inside of said strip.
Claim 15
Dependent Claim 17 words
A method according to claim 10 wherein more than one cord is employed to form said strip.
Claim 16
Dependent Claim 28 words
A method according to claim 10 wherein the cord is reversed at points staggered with respect to other reversal points to provide a distorted edge on the strip.
Claim 17
Dependent Claim 22 words
A method according to claim 10 wherein the angle of the cord across the width of the strip is changed between reversals.
Claim 18
Dependent Claim 28 words
A method according to claim 10 wherein continuous cord is disposed circumferentially of said strip and such cord is interleaved with the continuous cord forming the zigzag pattern.
Claim 19
Dependent Claim 16 words
A method according to claim 10 wherein the cord is associated with a green rubber belt.
Claim 20
Dependent Claim 24 words
A method according to claim 10 wherein rubber shoulder portions are disposed intermediate edges of said breaker strip and adjacent the edge portions thereof.
Claim 21
Independent Claim 148 words
A method of making a pneumatic tire including the steps of applying an endless reinforcement strip to a tire carcass, applying tread-forming rubber over said strip and carcass, and vulcanizing said tire; said strip comprising continuous cord forming a generally zigzag pattern and being positioned across the entire width of said strip from one side to the other at an angle to the edges of said strip with reversals at the edges, and lengths of said cord between reversals being interleaved with lengths disposed at an opposite angle along at least one line substantially parallel to and intermediate the edges of said strip whereby each length of cord between reversals has portions disposed on both the inside and outside of said reinforcement strip, and said adjacent lengths of cord forming a plurality of triangular portions between said interleaving lines and lengths of cord disposed at said opposite angle.
Claim 22
Independent Claim 148 words
A method of making a pneumatic tire including the steps of applying an endless reinforcement strip to a tire carcass, applying tread-forming rubber over said strip and carcass, and vulcanizing said tire; said strip comprising continuous cord forming a generally zigzag pattern and being positioned across the entire width of said strip from one side to the other at an angle to the edges of said strip with reversals at the edges, and lengths of said cord between reversals being interleaved with lengths disposed at an opposite angle along at least one line substantially parallel to and intermediate the edges of said strip whereby each length of cord between reversals has portions disposed on both the inside and outside of said reinforcement strip, and said adjacent lengths of cord forming a plurality of triangular portions between said interleaving lines and lengths of cord disposed at said opposite angle.
Claim 23
Dependent Claim 61 words

Claim 24
Dependent Claim 26 words
A method according to claim 20 wherein said tire cord changes position within said strip as the circumference thereof is substantially increased during the shaping step.
Claim 25
Dependent Claim 11 words
