Abstract:
A pluck-resistance measuring instrument for fastener members which comprises holder means for holding a fabric of a garment to which a fastener member is attached, securely around the fastener member, a plurality of clamp members capable of claiming the fastener member and moving in the direction normal to the surface of the fabric where the fastener member is attached to the fabric, and tension detecting means for measuring the tensile force that is applied to the clamp members, wherein said holder means is supported by lift means, said tension detecting means comprises a member providing a fulcrum, a mass lever pivotally supported at the fulcrum and a tension detector, said mass lever being coupled at one end to said clamp members and adapted to act on the tension detector at the other end, wherein the tension detector is a load cell and the other end of the lever rests on the load cell, the fulcrum and the mass distribution of the mass lever being set so that when the reference value has been attained the other end of the lever comes away from the load cell to no load.
