Claims37
A metal load bearing cord comprising at least two metal strands adapted to bear a tensile load, said metal strands comprising twisted metal filaments, wherein at least one of said strands comprises a weld part wherein the at least one of said strands is interrupted and welded together, wherein the weld part includes a welded part length, wherein said welded part length is at least 2.5 times a lay length of said metal load bearing cord.
A metal cord comprising at least two metal strands, said metal strands comprising twisted metal filaments, wherein at least one of said strands comprises a weld part wherein the at least one of said strands is interrupted and welded together, wherein an elongation at rupture of the at least one of said strands at said weld part is at least 30% of the elongation at rupture of the at least one of said strands away from said weld part, wherein the weld part includes a welded part length, wherein said welded part length is at least 2.5 times a lay length of said metal cord.
A metal cord comprising at least two metal strands, said metal strands comprising twisted metal filaments, wherein at least one of said strands comprises a weld part, wherein the at least one of said strands is interrupted and welded together, wherein an elongation at rupture of the at least one of said strands at said weld part is at least 30% of the elongation at rupture of the at least one of said strands away from said weld part, wherein a lay length of the at least one of said strands in said weld part is less than a lay length of the at least one of said strands away from said weld part.
