Abstract
The grippers are mounted on a doffer bar so as to disengage from both the top and bottom of the bar should a mis-alignment occur relative to a bottin tube. The removal or separation of a gripper from the bar causes a pneumatic or electrical signal to be generated which can be used to indicate the individual disturbance location. A light may also be provided at each gripper station in order to indicate a position of a disturbance.
