BEAD CORD AND VEHICLE TIRE

摘要

A bead cord (9) has an annular core (10) and a single line of side wire (11) spirally wound for multiple times in one layer around the annular core (10). The annular core (10) is formed by a twisted wire (13) formed by two core wires (12) twisted together. The core wires (12) have the same diameter. Both end surfaces of the core wire (12) forming the annular core (10) are joined by welding. The direction of winding of the side wire (11) relative to the annular core (10) is preferably opposite the direction of twisting of the core wires (12). ® KIPO & WIPO 2009
