A device for driving antiskid studs into stud holes of a tread of a pneumatic tire , the device comprising - a tire holder for holding the pneumatic tire to be studded, the tire holder defining an axial direction (AX) that is parallel to an axis of rotation (AX) of the pneumatic tire configured to be held by the tire holder , - a primary studding head comprising • a primary mouth for injecting a primary stud out of the primary studding head into one of the stud holes of the pneumatic tire in a primary direction (D410), • a primary bore for guiding the primary stud , the primary bore ending at the primary mouth , and • a primary pusher movable in said primary bore for pushing the primary stud out from the primary bore in the primary direction (D410), and - a primary rotator configured to rotate the primary studding head about an axis (AX400) that is parallel to the primary direction (D410), characterized in that - the primary rotator is configured to rotate the primary studding head about the axis (AX400) at least 180 degrees both to a first direction of rotation (R1) and to a second direction of rotation (R2), wherein the second direction of rotation (R2) is reverse to the first direction of rotation (R1), and - the primary rotator is configured to • rotate the primary studding head about the axis (AX400) in a continuous manner and • stop the rotation of the primary studding head at a freely selectable position. - a tire holder for holding the pneumatic tire to be studded, the tire holder defining an axial direction (AX) that is parallel to an axis of rotation (AX) of the pneumatic tire configured to be held by the tire holder , - a primary studding head comprising • a primary mouth for injecting a primary stud out of the primary studding head into one of the stud holes of the pneumatic tire in a primary direction (D410), • a primary bore for guiding the primary stud , the primary bore ending at the primary mouth , and • a primary pusher movable in said primary bore for pushing the primary stud out from the primary bore in the primary direction (D410), and • a primary mouth for injecting a primary stud out of the primary studding head into one of the stud holes of the pneumatic tire in a primary direction (D410), • a primary bore for guiding the primary stud , the primary bore ending at the primary mouth , and • a primary pusher movable in said primary bore for pushing the primary stud out from the primary bore in the primary direction (D410), and - a primary rotator configured to rotate the primary studding head about an axis (AX400) that is parallel to the primary direction (D410), characterized in that - the primary rotator is configured to rotate the primary studding head about the axis (AX400) at least 180 degrees both to a first direction of rotation (R1) and to a second direction of rotation (R2), wherein the second direction of rotation (R2) is reverse to the first direction of rotation (R1), and - the primary rotator is configured to • rotate the primary studding head about the axis (AX400) in a continuous manner and • stop the rotation of the primary studding head at a freely selectable position. • rotate the primary studding head about the axis (AX400) in a continuous manner and • stop the rotation of the primary studding head at a freely selectable position. <EOS>
