    Abstract: Provided are a steel cord for reinforcing rubber whose fatigue resistance is increased more than ever to enable achieving high durability that was not conventionally realized, and a pneumatic radial tire including the steel cord as a reinforcement member.In a steel cord for reinforcing rubber having a double-twist structure that includes a plurality of strands twisted together in the same direction with the same pitch and including a central structure and at least one outer layer, the central structure is composed of at least two strands being twisted around each other and each being composed of at least seven filaments being twisted together. In a steel cord for reinforcing rubber including at least three core strands being twisted together and at least six sheath strands being twisted together around the core strands, the core strands and the sheath strands are twisted in the same direction.

    Abstract: A steel cord (10) comprises eight or more strands (12, 14) twisted together. Each of the strands has a substantially same cord twisting direction and a substantially same cord twisting pitch in the steel cord, and each of the strands consists of two to five individual filaments (16, 18) twisted together. Such a multi-strand steel cord can be manufactured without having to twist the individual strands separately and beforehand.

    Abstract: A bundle of logs (62) is unitized by means of one or more log bundling strands (10, 20, 42, 64, 70) and one or more sleeves (43, 66, 80). Each of the bundling strands has a leading end and a trailing end. Each of the bundling strands (10, 20, 42, 64, 70) is wound around the logs to form the bundle so that the leading end (44) and the trailing end (46) run adjacent to one another over an overlapping length L1 and form a pair. One or more sleeves (43, 66, 80) have a length L2 which is smaller than the overlapping length L1. Each of the one or more sleeves (43, 66, 80) are crimped on one pair of the leading ends (44) and the trailing ends (46) within the overlapping length L1. At least some of the bundling strands (10, 20, 42, 64, 70) are provided with indents (26, 36, 47) or protrusions (76) at the outer surface and/or at least some of the sleeves (80) are provided with non-cylindrical inner surfaces. The indents (26, 36, 47), protrusions (76) and/or non-cylindrical inner surfaces improve gripping between the strands (10, 20, 42, 64, 70) and the sleeves (43, 66, 80) and / or reduce the length L2 of the sleeves (43, 66, 80).
