Annular metal cord and endless metal belt |
摘要 |
An annular metal cord includes an annular core portion and an outer layer portion. The annular core portion is formed by connecting together both ends of a first strand material which is made up of six twisted first metal filaments. The outer layer portion is formed by winding spirally a second strand material which is made up of six twisted second metal filaments around the annular core portion. The second strand material is wound at a predetermined winding angle relative to a center axis of the annular core portion, and a winding initiating end portion and a winding terminating end portion are connected together. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.
