INSPECTION METHOD AND APPARATUS FOR INSPECTING FASTENER SLIDERS WITH AUTOMATIC LOCK MEANS Abstract of the Disclosure An inspection method for fastener sliders with automatic lock means in which at the final step in the assembly operation of said slider, the pull tab of said slider is applied a down- ward biasing force thereto by a predetermined constant stroke of a dial gauge and the quality of the slider is determined by electrical detection signals which detect whether or not the balance between the resilient pressure provided by the dial gauge and the repulsion force of the pull tab falls within a predetermined range. An inspection apparatus for fastener sliders with automatic lock means comprising an intermittent transfer member holding and transferring said slider, a dial gauge supported on a reciprocal mechanism for moving upwardly and donwardly by a predetermined constant stroke, a resilient biasing rod disposed on said reciprocal mechanism adjacent to said dial gauge and a detecitng mechanism for electrically detecting whether or not the rotation of the pointer of the dial gauge falls within a predetermined range.
