ZENIT 47
YARN STRUCTURE
VCV (Option)
Variable CV Channel
The clearer calculates continuously the VCV values from the
yarn pieces with the set check length and compares these
with its floating mean value.
Note :
These values cannot be compared with the optical CV
values of the statistics or the data collected in the laboratory
because the check lengths as well as the cutting lengths for
calculation are different.
+ Limit /– Limit (%) )
When the set limit values are exceeded (± 5% to ± 100%),
i. e. as soon as the VCV value deviates accordingly from the
mean value, a cut or a spindle blockage takes place with the
respective extraction length (1 to 50 m).
Length
The check length can be set between 1 m and 50 m.
+ Cuts /– Cuts
The number of cuts due to a positive or negative deviation of
the yarn diameter are listed separately.
Difference (%)
The deviation of the VCV value transmitted last in the current
group, relative to the mean value, is displayed. This allows for
optimizing the limit values.
Note : A first-time display of the deviation is performed after
4 km of wound yarn as from an adjustment.
