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).
