A gripper thread bobbin (26) is movably arranged on the pin in a direction of the axis, and includes flanges (28, 29) that are spaced apart from each other, where the flanges are connected to a hollow boss (27). A brake spring and an exhaust spring i.e. cylindrical helical spring, enclose the pin, and the case is reinforced at a region of the base, and the bobbin is reinforced in an opening (31) of the boss.
