ABSTRACT:
Apparatus and method for locating the bung opening of a container such as a drum. The container is rotated about its axis to move the bung opening along a generally circular path, and a locator pin with a pivotally mounted follower arm is positioned in the path of the opening so that the follower arm will travel along the wall of the container, then pivot and enter the opening when the pin is aligned with the opening. The pivoting of the follower arm is detected by an interruption of air flow through a discharge opening which is obstructed when the arm is in position to enter the opening.
