A bottle gripper for handling a bottle when depositing powder paint on the bottle in an electrostatic powder coating process and the like, the gripper comprises a cylindrical arm in which a shaft is inserted coaxially for relative movement in an axial direction. Several swingable pieces are attached to and are linked between the arm's lower end and the lower portion of each of the pieces, which forms a short thin cylindrical shell when gripping a bottle and is wrapped in a hat-shaped cover made of resilient material such as rubber with the outer rim of the resilient cover being fixed to the lower end of the arm in order to protect against entry of powder particles into the swing mechanism. The resilient cover is closed or opened by the relative movement between the arm and the shaft when gripping or releasing the head of a bottle. |
