Specimen grip for steel strip cord

• The symmetrical weight distribution allows the center of gravity of the grips in the tensile axis. No transverse forces are transmitted to the load cell via the specimen grips.
• A guide groove is integrated into the load reduction roller and basic unit for thread feeding, allowing fast and convenient specimen feeding and automatic and precise positioning in the tensile axis.
• Force reduction curve employing 270° deflection reduces the tensile force on the end-clamping position. Thus the required closing force can be reduced at end clamping for specimens that are sensitive to clamping. The closing force is progressively loaded at end clamping, thereby securely holding the specimen and preventing jaw breaks during the test.
• The load reduction radius is reduced seamlessly via the involute form of the load reduction roller.
• The ends are clamped pneumatically, ensuring that the gripping force remains constant even with diminishing specimen diameter.
• Easy and convenient opening and closing via pneumatic control unit allowing high specimen throughput.

The grips are especially suitable for steel tire cords to BISFA.
