ABSTRACT:
There is disclosed apparatus for measuring forces applied to a pull tab during the formation of an opening in a can end having an upper and lower surface with the pull tab hingedly secured to the upper surface and a source line in the can end defining an opening. A sample set of such can ends is batched loaded, by different plant technicians monitoring different can end forming machines, into a feed chute of the testing apparatus. The individual sample sets are separated from each other with special coded can ends. As each can end is fed into the testing apparatus, it is interrogated by a sensing arrangement which determines the presence of a physical characteristic unique to the coded can end signifying the completion of testing of a particular sample set. In this manner, the host computer precisely correlates the test data of each individual can end with relevant production data.
