AUS ZWEI GRUPPEN VON FILAMENTEN (M+N) BESTEHENDES STAHLSEIL |
摘要 |
A steel cord (30) consists of a first group and a second group. The first group comprises two or more plastically deformed outer steel filaments (10) twisted around each other with a first twist pitch and the second group comprises one or more plastically deformed inner steel filaments (20) twisted around each other with a second twist pitch. The second group is twisted around the first group with a cord twist pitch. One of the inner or the outer steel filaments having a part load elongation of x %, all the other inner and outer steel filaments having a part load elongation of y %, whereby x and y fulfil the equation: x-0.10</=y</=x+0.10, and where all the inner and outer steel filaments have a deforming pitch that is substantially equal to the cord twist pitch. |
