YARN CLEARING GENERAL
Short Fault and Long Fault Combined
Exact inspection of a yarn fault shows that it changes along
the longitudinal dimension. A thick place is made up of a com-
bination of different thickenings.
For classification, this fault is only characterized after it has
completely run through the measuring field of the sensing
head.
The different cross dimensions of the long fault are cal culated
as a mean value. The average thickening is then lower relative
to the largest cross-dimension of the yarn fault. Therefore the
yarn fault is assigned to the long fault class.
Depending on the yarn and the selected setting it is therefore
possible that, at simultaneous short and long faults, the sum
of the cut short and long faults in menu Monitoring Data and
the sum of the cut short and long faults in menu Class Data
show differences.
For simultaneous short and long faults it is recommended to
apply the class clearing in combination with the conventional
clearing. Better results can thus be achieved.
