BONDING STRENGTH TESTER
To consists of a spring dynamometer to indicate the load applied at the junction of the sole and the upper, a lever arrangement to transmit the load exerted on the toe piece to the spring dynamometer, a straight edge fulcrum for resting the shoe on during the test, and a set of interchangeable toe-pieces having different curvatures.
The spring dynamometer indicates the load applied on the joint directly in kilograms, taking into account the mechanical advantage of the lever transmitting the force from the toe-piece to it. The load is indicated on a circular dial. The dynamometer has two pointers, a black pointer to indicate the instantaneous load acting on the toe-piece, and a red dummy pointer to indicate the maximum load applied before the failure of adhesion.Technical Data
