compressed to eliminate air porkets and the measurement is taken. The fineness test begins
with weighing a fiber sample of between 9.5 and 10.5 grams the balance. The operator
inserts the weighted sample into the mike chamber and closes the door. When the chamber
door opens and the sample is ejected, the test is complete. When all tests on the right
console are complete, the results and flags appear on the display and tests on the next
sample may be started.
       A second operator begins the length and strength tests on the left console when
READY appears in the error line of the display. The sample ID number and mike value are
automatically transmitted from the right to the left console. Length and strength tests are
performed on a sample within a single test cycle.
       Once length / strength tests on one sample are complete, average test results appear
on test display and the next test may be run as soon as READY appears in the error line.
The operator puts the bale sample into the Fibrosampler cylinder and prepares a test
sample that is clamped by a Fibrocomb.
       The prepared Fibrocomb is placed into the comb track. Here the sample beard is
automatically brushed. Brushing is for removing loose fibers and cleaning and aligning the
remaining fibers. When the brushing is complete, a mechanical finger slides the
Fibrocomb into the comb holder that faces the fixed lens and jaw system.
       The instrument optically scans the sample to determine length. Then the jaws clamp
on the fibers and the rear jaw retracts until the sample is broken. The microprocessor
calculates strength and elongation.

                                          Finish

      As tests are competed for each sample, a printer produces a hard copy of the results.
