Apparatus for testing the release torque of container caps

Apparatus for testing for a predetermined level of minimum release torque of container caps at a torque testing station in said apparatus, said apparatus comprising:

• A. Means for clamping capped containers at said station;
• B. Means for grasping the caps of said containers at said station;
• C. Means connected to said cap grasping means for applying a predetermined level of minimum release torque to said container caps;
• D. Means for sensing the levels of release torque applied to said caps and providing corresponding signals indicative of said levels;
• and,
• E. Means coupled to both said torque applying means and said sensing means and constructed and arranged to check and selectively adjust the level of said minimum release torque to insure that said minimum release torque is applied at said predetermined level.
