Abstract
Reinforcement cord for elastomeric products, in particular reinforcement cords, for use in vehicle tires comprising inner filaments (1) and at least one outer filament (2) wound helically around the inner filaments (1), characterised in that at least the outer filament (2) has a flattened cross-section and is so dimensioned and positioned that it substantially co-determines the mechanical characteristics of the reinforcement cord via line-like and/or area contact locations with the inner filaments (1).
Claims23
A reinforcement cord for elastomeric products comprising a plurality of inner filaments and at least one outer filament wound helically around the inner filaments wherein at least the outer filament has a flattened cross-section and is so dimensioned and positioned that it substantially co-determines the mechanical characteristics of the reinforcement cord via line-like and/or area contact locations with the inner filaments, wherein
- the cross-sectional area of the at least one outer filament is in a range substantially from 50 to 100% of the total cross-sectional area of the inner filaments, and
- the lay of length of the at least one outer filament is between 20 to 40 times as large as the largest cross-sectional dimension of the at least one outer filament.
A reinforcement cord for elastomeric products comprising a plurality of inner filaments and only one outer filament wound helically around the inner filaments wherein the one outer filament has a flattened cross-section and is so dimensioned and positioned to substantially co-determine the mechanical characteristics of the reinforcement cord via line-like and/or area contact locations with the inner filaments, wherein
- the cross-sectional area of the one outer filament is in the range substantially from 50 to 100% of the total cross-sectional area of the inner filaments, and
- the lay of length of the one outer filament is between 20 to 40 times as large as the largest cross-sectional dimension of the one outer filament.
