After the optical measurement, the jaw system comes into
play as the sample is positioned for clamping
The jaws, faced with a maintenance-free urethane lining, clamp on the fiber on a
1/8-inch gauge basis. The rear jaw retracts at a constant rate of extension under the control
of precision step motors and the sample is broken. A highly sensitive force transducer is
used to monitor the force required to break the sample and the microprocessor calculates
the strength of the fiber. Once the sample is broken, all components return to their original
positions, sample debris is removed by vacuum and the Fibrograph is ready to test the next
sample. At the end of the testing procedure, all results are compiled and a hard-copy,
comprehensive profile of each bale tested is produced by a printer, which is included as
standard equipment. As an option the information can also be sent to a host computer.
