PURPOSE: To eliminate difficulties of handling calendered inserts for radial tires or other rubber products during manufacture thereof. CONSTITUTION: In a manufacturing method of a steel strip, the steel strip 1 comprises 2 to 7 round steel filaments 2 lying adjacent to one another so as to form a single plane of core filaments and one or more filaments 4 which are wrapped around the core filaments in one single wrapping direction. One or more core filaments, individually or the plane of the core filaments as a whole, have residual elastic torsions to such an extent that the strip remains substantially flat over the whole length of the strip if the strip is not subjected to external forces. |
