PLUCK-RESISTANCE MEASURING INSTRUMENT FOR SNAP MEMBERS

摘要

An instrument for measuring the pluck resistance of snap-members has a presser for pressing the fabric of a garment to which a snap member is attached, securely around the member and a plurality of jaws for constraining the sides of the snap member. A tensile force pulls the snap member away in the direction at right angles to the fabric surface to which the snap member is attached and a gauge measures the tensile force.
