A gripper unit includes a gripper body and first and second arcuate fingers that are pivotally mounted on the gripper body for rotation about parallel first and second axes. The first and second fingers have inner surfaces that face each other, each of the inner surfaces including longitudinal grooves. A gripper assembly of this configuration may be particularly suited for gripping bottles of different sizes and configurations, particularly those that have a lip or ridge on the bottle neck.
