"A STEEL CORD FOR THE REINFORCEMENT OF TIMING BELTS OR TRANSMISSION BELTS"
Application 1066/DEL/1997 published 2008-07-25, filed 1997-04-25
A steel cord (10) for the reinforcement of timing belts or transmission belts comprises only two to five strands (12) tightly twisted with each other in a first direction at a cord twisting pitch. Each of said strands (12) comprises only two to seven steel filaments (14) tightly twisted with each other in this first direction at a strand twisting pitch. The steel filaments (14) have a diameter ranging from 0.03 to 0.40 mm. The ratio strand twisting pitch to filament diameter is greater than 30, the ratio cord twisting pitch to filament diameter is greater than 30, and the ratio cord twisting pitch to strand twisting pitch is greater than 1. Such a steel cord has an acceptable low torsion moment under axial loads. No. of Pages : 17 No. of Claims : 5
