    摘要： A mould (200) for manufacturing a tire (100). The mould (200) comprises a plurality of segments (211, 212, 213, 214, 215, 216, 217, 218) including a first segment (211). The first segment (211) comprises a first end (221), an opposite second end (222), primary lamella blades (511) that are arranged close to the first end (221), and secondary lamella blades (512) that are arranged far from both the ends (221, 222). An average of the heights of the primary lamella blades (511) is at least 75 % of an average of the heights of the secondary lamella blades (512). A bending strength of the primary lamella blades (511) against bending in a circumferential direction (C) of the mould (200) is greater than a bending strength of the secondary lamella blades (512) against bending in the circumferential direction (C) of the mould (200). A tire manufactured by the mould.

    摘要： A device (100) for driving antiskid studs (800, 911, 912) into holes (920) of a tread (930) of a pneumatic tire (900). The device (100) comprises a tire holder (210) for holding a pneumatic tire (900) and a studding tool (300). The studding tool comprises a primary and a secondary studding heads (400, 500) both studding heads comprising a mouth (410, 510) for injecting a stud (911, 912) out of the studding head (400, 500) into one of the holes (920) in a direction (D410, D510), a bore (420, 520) for guiding the stud (911, 912), the bore (420, 520) ending at the mouth (410, 420), and a pusher (430, 530) movable in said bore (420, 520) for pushing the stud (911, 912) out from the bore (420, 520). The studding tool (300) and/or the tire holder (210) moves relative to each other at least in a direction that has a non-zero component in an axial direction (AX).
