HOW TO DECIDED BOTTOM ROLLER SETTING

BOTTOM ROLLER SETTING:-

     WE NEED AFIS REPORT 5%SPAN LENGTH FOR BOTTOM ROLLER SETTING

 FIRST FOR WE ENSURE IN WHICH PROCESS WE HAVE. LIKE COMMONLY 2 PROCESS RUN COTTON MILL

ONE WAS CARDED PROCESS ANOTHER ONE WAS COMBED PROCESS

 CARDED PROCESS:-

 BREAKER DRAWFRAME

 5% SPAN LENGTH = 38

 BOTTOM ROLLER SETTING = 38/42

 FINISHER DRWFRAME

 5% SPAN LENGTH = 39

 BOTTOM ROLLER SETTING = 39/43

 

COMBED PROCESS:-

 BREAKER DRAWFRAME

 5% SPAN LENGTH = 38 +1 OR 2 MM

 BOTTOM ROLLER SETTING = 39/43 OR 40/44

 FINISHER DRWFRAME

 5% SPAN LENGTH = 39

 BOTTOM ROLLER SETTING = 39/43

 

NOTE:-

     IN COMBED PROCESS WE GIVE 1OR2MM OPEN SETTING IN BREAKER DRAWING. DUE TO BETTER NOILS REMOVAL IN COMBER

 IN AFIS REPORT 5%SPAN LENGTH DECIDED BOTTOM ROLLER SETTING. WE CHOOSE WRONG SETTING LIKE CLOSE WE FACE HIGH BREAKS IN RINGFRAME, ABNORMAL CUTS IN AUTOCONER,HIGH CLASSIMATE FAULT. BUT WE GET BETTER IMPERFECTION.

 IN CASE OPEN SETTING WE FACE LOW BREAKS IN RINGFRAME, LOW CLASSIMATE FAULT. BUT WE GET WORST IMPERFECTION.
