Abstract

A tensile testing apparatus comprises a magazine or holder for test specimens. The specimens are disposed horizontally with their end portions constrained by U-shaped channels. Slots at the lower ends of the channels are provided for pulling the lowermost test specimen therethrough under the action of robot fingers, the fingers pulling the specimen to a 90 degree slide whereupon the fingers are lowered and the test specimen slides down the slide and is rotated 90 degrees before coming to rest on seats at the ends of the slides. The now retracted robot fingers are turned 90 degrees and spread apart for movement toward the test specimen which is then gripped and lifted upwardly from the seats and then transferred to a testing machine, tested and then removed from the testing machine.
