This gripper completes the range of 3-fingers screwing grippers.
It permits to screw square or prismatic caps, but also to reduce the cycle time by releasing the bottle by opening the gripper without vertical movement (if the system permits to index the rotation of the gripper). The gripper is waiting the next bottle without up-down movement.
With a tightening torque of 27 Nm, this generally permits to screw a cap up to 5 Nm by adhesion or up to 8 Nm if the cap is not cylindrical.
