YARN STRUCTURE

 Off Count

These settings make possible the detection of false bobbins 
or yarn with a larger off-count deviation.

 + DiaDiff /– DiaDiff 

Depending on the quality or irregularity of the yarn, a dia-
meter deviation between ±3% and ±44% (difference to ba-
sic value) can be selected. It can be set independently for the 
positive as well as negative diameter deviation. 

 Coarse / Fine

According to the diameter deviation set, the yarn count devia-
tion is displayed for 

Coarse

 and 

Fine

.

CntLen

The reference length in which the average diameter differ-
ence is determined can be set between

 

10 and 50 m

This 

allows for optimizing the detection of bobbin misplacements 
and count variations.

+  Cuts /– Cuts 

The number of cuts due to a positive or negative deviation of 
the yarn diameter are listed separately.

This display makes possible the optimizing of the settings.

 Short Off Count

CntLen

As opposed to the yarn count channel, the shorts count chan-
nel allows separate acquisition of yarn with a 

count devia­

tion over a length of less than 10 m.

 The reference length 

determining the average yarn count deviation can be set be-
tween 1 and 32 m.
