The hybrid cords are composed of a first twisted textile yarn made of a first material and a second twisted textile yarn made of a second material. The ends of the two yarns are twisted with each other. The first twisted textile yarn is a polyketone yarn and the second twisted textile yarn is a polyester yarn. ## Claims ### Claim 1 A strength element ply for elastomeric articles of manufacture, comprising: strength elements formed of hybrid cords disposed in a substantially parallel arrangement within the ply; and said hybrid cords being formed of polyketone yarn forming a first twisted textile yarn and of polyester yarn forming a second twisted textile yarn; wherein said first twisted textile yarn of polyketone and said second twisted textile yarn of polyester are end-twisted together. ### Claim 2 (depends on 1) The strength element ply according to claim 1, wherein said second twisted textile yarn is a polyester yarn selected from at least one member of the group consisting of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), and polycarbonate (PC). ### Claim 3 (depends on 1) The strength element ply according to claim 1, wherein said second twisted textile yarn has a linear density in a range from 400 to 2200 dtex. ### Claim 4 (depends on 1) The strength element ply according to claim 1, wherein said first twisted textile yarn has a linear density in a range from 400 to 2200 dtex. ### Claim 5 (depends on 1) The strength element ply according to claim 1, wherein at least one of said first twisted textile yarn and said second twisted textile yarn is end-twisted at 150 to 600 t/m to form a respective said hybrid cord. ### Claim 6 (depends on 1) The strength element ply according to claim 1, wherein at least one of said first twisted textile yarn and said second twisted textile yarn is end-twisted at 380 to 480 t/m to form a hybrid cord. ### Claim 7 (depends on 1) The strength element ply according to claim 1, wherein at least one of said first twisted textile yarn and said second twisted textile yarn comprise an adhesive impregnation enabling an adherence of said strength elements to rubber. ### Claim 8 (depends on 1) A method of manufacturing a pneumatic vehicle tire, comprising: providing a strength element ply according to claim 1 and integrating the strength element into the vehicle tire during a manufacture thereof. ### Claim 9 (depends on 1) A pneumatic vehicle tire, comprising a strength element ply according to claim 1 integrated into the vehicle tire. ### Claim 10 (depends on 9) The pneumatic vehicle tire according to claim 9, wherein said strength element ply is disposed as a belt bandage and/or as a bead reinforcer in the tire. ### Claim 11 (depends on 1) A conveyor belt comprising a strength element ply according to claim 1 integrated into the conveyor belt. ### Claim 12 (depends on 1) A flat belt comprising a strength element ply according to claim 1 integrated into the flat belt. ### Claim 13 (depends on 1) A flexible woven-fabric tube comprising a strength element ply according to claim 1 integrated into the flexible woven-fabric tube. ### Claim 14 (depends on 1) An air bellows comprising a strength element ply according to claim 1 integrated into the air bellows.
