Abstract:
A cord having a structure which facilitates visual detection of core filament mislocation, comprising of:a core structure consisting of 1 to 4 core filaments, said core filaments having a first diameter greater than 0.15 mm and less than 0.40 mm; one single layer consisting of n+m layer filaments, said layer filaments having a diameter of at least the first diameter of the core filaments minus 0.05 mm and no greater than the first diameter of the core filaments minus 0.015 mm, n being equal to the number of core filaments and m being equal to six if n is greater than one and being equal to five if n is equal to one; said layer filaments and said core filaments being twisted in a same direction and at a same pitch; and wherein a surface of said core filaments is visually different from a surface of said layer filaments so that said surfaces can be visually differentiated by the naked, unaided eye of a person with ordinary visual capacities and a determination made if core mislocation has occurred or not.
