ABSTRACT:
An improved apparatus for on-line inspection of an intermediate-stage, headed, non-threaded blank for a threaded fastener is disclosed. If the blank fails to meet specifications, the production of blanks is terminated. Improvement features include a roll-sorter for testing all blanks to see if certain dimensional parameters of the blank's head are satisfied. Then, random chosen acceptable blanks are fed to a rotatable table which is constructed to receive a sample blank for movement of the blank to a test station where the blank is tested for other failures to meet dimensional specifications. The rotatable table is constructed to provide interchangeable elements thereof that will accept blanks of different head and stem sizes. Multiple adjustability is provided in the means for transferring blanks, that are first acceptable to the roll-sorter test, on to the rotatable table for further testing.
