To determine and analyze sliver, roving and spun yarn’s evenness and the

evenness of structure . Applicable to silver, roving and spun yarn made of

cotton, wool, synthetic fiber, linen and blended yarn, etc.

Drawing mechanism adopts dual-motor drive mode to achieve non-silp of

sliver. Large size of roller to lower rotate speed with unique aseismic design

and more stable transmission. Roller is available for auto open-close, auto

scaling, and can be used in revising direction, which reduces the abrasion

for roller from yarn, and extend service life of roller.

Wave spectrogram can display wavelength value, unevenness curve can be

scaled freely. With larger data retrieval function.

1. Can measure the unevenness of roving, sliver.

2. Automatic zero, and automatic adjust average, operation more convenient,

more efficient.

3. The unevenness curve can be saved, playback, and mark defect position on

the uneven curve.

4. Automatic alarm when sliver break off during testing.

5. Powerful statistical analysis, providing annual and monthly product quality

analysis and quality trend in graphic , provides the basis reference for

scientific management users.

6. Using a graphical interface, cooperate with control panel key board to

achieve complete testing by a key operation.
