Abstract
Abstract A metallic cable adapted to be used to advantage for reinforcing various types of elastomeric articles such as belts and motor vehicle tires has a core formed from two or more metallic filaments wound together into a helical shape without twisting one filament about the other whereby each core filament lies in line contact with at least one other core filament, the line of contact being parallel to the direction of the filament and a helically wound wrapping filament is disposed about the core filaments. The wrapping filament is helically wound at the same lay and hand as the core filaments and is positioned on the inside of the helix formed by the core filaments.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A reinforcing cable for elastomeric articles comprising helically formed filaments, one or more single metal wrapping filaments wound on two or more single metal core filaments that are not wound about one another, characterized in that the core filaments are of substantially identical helical shape and are positioned beside and against each other whereby each core filament is in line contact with at least one other core filament, the line of contact being parallel to the direction of the filament, and the wrapping filaments are in the form of a helix having the same hand and the same pitch as the core filaments and are positioned on the inside of the helix formed by the core filaments.
Claim 2
Dependent Claim
117 words
A reinforcing cable for elastomeric articles comprising helically formed filaments, one or more single metal wrapping filaments wound on two or more single metal core filaments that are not wound about one another, characterized in that the core filaments are of substantially identical helical shape and are positioned beside and against each other whereby each core filament is in line contact with at least one other core filament, the line of contact being parallel to the direction of the filament, and the wrapping filaments are in the form of a helix having the same hand and the same pitch as the core filaments and are positioned on the inside of the helix formed by the core filaments.
Claim 3
Dependent Claim
32 words
A reinforcing cable according to claim 1, provided with one wrapping filament, characterized in that the wrapping filament is shifted half a pitch length relative to the pitch of the core filaments.
