How does ABS work ?

BarcoProfile-ABS is installed on the yarn

withdrawal tube.

Based on a patented operating principle, the

ABS detector measures the quantity of light

absorbed by the yarn.

For that purpose, light emitting diodes and

photoreceivers are put on the outside of the

yarn withdrawal tube, part of which has been

made diffusely transparent. The part of the

withdrawal tube where textile technological

functions, such as yarn twist formation, are

accomplished, is not touched.

The receivers sense the total amount of light

present in the tube. Foreign fibers in the yarn

cause an increased light absorption. This

increase is measured by the detector.

Measurements are unaffected by external

conditions such as temperature, ambient light,

humidity, dust and fiber type.

Functionalities

- Correct detection of foreign fiber length. The

ABS detector looks at the yarn from all

angles. This concentric detection allows to

see the full length of the foreign fiber

resulting in accurate length determination

of the contamination. This, in turn, allows

very selective clearing, avoiding un-

necessary stops.

- On-line defect classification per rotor and per

machine.

- Easy setting of clearer limits based on length

and intensity of contamination.

- Detection of contaminated sliver cans,

preventing chains of contamination in the

yarn (swarms).

- Foreign fiber rotor lock in case too many

stops within a certain yarn length are

generated.

- Auto-diagnostics prevent production to

continue on a rotor with a defective sensor.
