发明名称 STEEL CORD WITH IMPROVED FATIGUE STRENGTH
摘要 A steel cord (1) for the reinforcement of elastomers, especially for the reinforcement of breaker layers in a tire, said steel cord comprising two strands of at least two filaments (11, 12) each, said strands being twisted around each other and forming helicoids of a same pitch, the filaments (11) of the first strand having a pitch differing from the pitch of said helicoids and having a value of more than 300 mm, the filaments (12) of the second strand having the same pitch as said helicoids and being twisted in the same sense as said helicoids, all the filaments of both of said strands having a diameter between 0.08 and 0.45 mm, wherein the diameter of the filaments of one of said strands is at least 0.02 mm greater than the diameter of the filaments of the other of said strands. Preferably the diameter of the filaments (12) of said second strand is at least 0.02 mm greater than the diameter of the filaments (11) of said first strand.
