CONVENTIONAL SLIVER QUALITY MONITORING WITHOUT
USTER® SLIVERGUARD AND SILVER MONITORING

The conventional OFFLINE quality monitoring of the sliver by check the count and the unevenness values and by visual check of the spectrogram only 2 to 3 times per shift creates following problems and insecurities:

  • Only a very short sliver production is supervised (less than 0.02%).
  • The moment of a wrong sliver quality produced by a default on the machine is not known.
  • Thick places in the sliver can not be captured.
  • In case of autolevelling drawframes, the performances are not perpetually supervised.
 
100% QUALITY MONITORING OF THE SLIVER PRODUCTION HELPS YOU
  • to optimize the spinning process
  • to increase the yarn quality
  • to increase the productivity
  • therefore, to reduce the costs
 

STANDALONE SLIVER QUALITY MONITORING BY USTER® SLIVERGUARD

The full automatic ONLINE quality monitoring of the sliver by the 100% supervision of the count deviation and the evenness values with a high powerful thick places detection assure a high sliver quality respectively yarn quality.

 





USTER® SLIVERGUARD CAN BE INTRODUCED ON DRAWFRAME, CARD AND COMBER MACHINE AS A RETROFIT SOLUTION
 
SLIVER COUNT/WEIGHT DEVIATION A%
  • Indication of the actual and the 100 m sliver count deviation.
  • Supervision of the sliver count deviation according to a pre-set sliver length.
  • Immediately machine Stop with Alarm indication in case of a sliver count/weight exceeding a pre-set deviation limit.

The supervision of the sliver count deviation assures that the machine is producing 100% the right sliver count.

 

SLIVER EVENNESS CV%

  • Indication of the 100 m sliver evenness.
  • Supervision of the sliver evenness according to a pre-set sliver length.
  • Immediately machine Stop with Alarm indication in case of a sliver evenness exceeding a pre-set evenness limit.


The supervision of the sliver evenness assures that the machine is producing 100% the right sliver evenness.

 

 


THICK PLACES TP

  • Indication of the number of thick places during production according to a preset amplitude limit.
  • Immediately machine Stop with Alarm indication in case of a thick place in the sliver exceeding a preset amplitude limit.
  • The supervision of the thick places prevents unnecessary stops in winding and OE spinning and eliminates problems with short count variation in yarns.

CENTRALIZED CONTROL OF THE SPINNING PREPARATION
  • Key quality and production information is provided at the manager’s desk.
  • All data from each single machine is available for central management in one PC.
 

ULTRA-LONG MACHINE HISTORY

  • Managers can optimize the key performance parameters of the entire spinning preparation department.
  • The system supports total comparison of all machines over long periods of time.
  • Compares directly to USTER® STATISTICS.

 

 

PERIODIC FAULTS IDENTIFIED BY SPECTROGRAM
  • 100% online monitoring with high frequency analysis of spectrogram identifies all periodic faults in the sliver.
 

 

 

 


POWERFUL ANALYSIS TOOL, EASY TO USE

  • The Knowledge Based System supports the managers to immediately find out the source of quality deviations in the gear plans.




IDEAL TO OPTIMIZE THE SPINNING PERFORMANCE

  • High quality sliver allows to run highest speed in spinning and improves overall yarn evenness.
