ABSTRACT:
An apparatus is provided for non-destructively testing for a predetermined minimum release torque of container caps on containers at a torque testing station. The apparatus includes a device for clamping the containers at the torque testing station; a device for grasping the caps of the containers at the torque testing station; a device connected to the cap grasping device for applying a release torque to the container caps; and, a device including a strain gage coupled to the release torque applying device for sensing the level of release torque applied to the caps and providing a signal indicative of such level. The apparatus also includes selectively operable controls for destructively testing selected capped containers, on a sampling basis, to determine the actual release torque of the container caps on such containers.
