Grips with 360° deflection

360° deflection

The pneumatic grip for yarn and tire cords is a single actuator grip used on filamentary tensile specimens.

Advantages & features

Function description

Force reduction curve employing 360° deflection carefully reduces the tensile force on the clamping position. The pneumatic clamping ensures a constant gripping force and can be easily and reproducible set. The specimen is held securely, jaw breaks are avoided.

Advantages

Secure holding of the specimen ensures reliable test results, even with specimens prone to shrinkage.

High specimen throughput thanks to quick specimen insertion and centering via guide groove.

The load-reduction curve ensures gentle gripping with no jaw breaks.

The jaws can be changed quickly and easily for different applications - no tools required. The jaws are centered automatically.

Pneumatic Control Unit for Specimen Grips

The closing force of the pneumatic grips can be steplessly set via a pneumatic control unit, which ensures safe gripping of a wide range of different materials. The opening and closing of the specimen grips can be controlled by foot switches or via the remote control of the materials testing machine for greater operating comfort.
