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 CLASSI...

CONTROL UKG IN RINGFRAME :- 1)Working with Lower Ring frame TM 2) Working with Lesser Ring dia 3) Lift conversation 4) Correct usage of combination of RF empty Tube vs Spindle height (20 mm ) 5) Maintain correct speed curve, high speed reach before 25% of final length of the yarn to be produced 6) Usage of Higher efficiency of Main motor(94.5%) 7) Avoid Light doffs and check doff has to fall at set doff length meter 8) Usage of Energy efficient Fan motor( Less weight Fans ) 9) Instead of continuous running of OHTC from one to another end of the Ringframe, every reversal attend of the machine, We can stop OHTC for 1-5 minutes 10) Usage of light weight cops in ringframe 11) Maintain proper schedule of Spindles replacing 12) Maintain proper Jockey pulley servicing and greasing 13) Working with short strech conversation 14) Working with energy saving spindle tapes 15) Maintain perfect schedules of motor greasing and other elements bearings The following precautions to be taken while cond...

TYPES OF SPILCERS:- MURATAC AUTOCONER (By JAPAN)      They are manufacturing with own technology patent splicers   1) Mach splicer ( Air splicer ) 2) Water splicer -1 3) Water splicer -2 “Mach splicer”: It is working with Air and it will use for all kind of cotton and synthetic yarns  “Water splicer - 1” It is working with Water with Air and it will use for Plie yarns and wet spun linen  “Water splicer - 2” It is working with Water and with Air and it will use for Core yarn SCHALAFORST AUTOCONER (by Germany)      They are manufacturing with their own patent splicer 1) “Standard splicer“ It is using for all types of  cotton yarns (Air principle) 2) “Injection splicer” It is useful for High Twist yarn (Water with Air Principe) 3) “Thermos splicer” It is useful for Synthetic and Siro type yarns (Heated with Hot Air) 4) “Elasto Splicer” It is useful for soft core yarn (It can also be combined with  injection splicing facilit...

REASON FOR COP REJECTION :- DIFFERTENT COP CONTENT RING TRAVELLER SHEDULE NOT MAINTAIN NOT MAINTAIN R/F CLG RING TOUCH COPS HIGH CLEARER CUTS SPACER MISMATCH  SPACER NIL SPINDLES PREMATURE DOFF RINGRAIL SETTING HAIRNESS COPS MACHINE RELATED:- GRIPPERARM FAILURES POOR SPLICE QUALITY TENSION BREAKS IMPROPER PEG SETTING IMPROPER LENGTH SET WORK PRACTICE:- IMPROPER METHOD OF COP FEEDING ​

FACTORS AFFECTING CARDNG U :- •  Material transfer between cylinder & doffer should be proper •  Optimum tension draft •  RH% within recommendation •  Avoid lap licking and uneven lap •  No waste deposition on the redirecting roller grid •  Replace the wornout gears & wheels & loose keys. •  Ensure no loading on cylinder and doffer. •  Cylinder cover plate settings should be uniform •  Uniform chute feed roller settings  •  Proper feed roller movement & chain tension   •  Feed roller spring tension should be maximum and uniform. •  Proper tension on the sliver between scanning roller and coiler. CONTROL OF 5 MTR  CV% •  Sample size: 6 yards, 20 samples •  Scanning roller settings at front & back as per recommendation •  Ensure delivery & feed sensor calibration  •  Scanning roller should be free from waste & fluff •  Chute feed roller settings should be un...

MAJOR POINTS TO CONSIDER FOR REDUCE THIN -30% 1) In Blowroom fibre Damage to be avoided. 2) Carding Feed plate to lickerin to be take trial. 3) More Singles running in Comber. 4) Stop motion functioning to be effectively in Drawframes & Comber. 5) Optimse Drawing roller setting as per Afis 5% length. 6) Rsb Top roller pressure and cots dia 7) Optimise drawframe creel drafts and other drafts also 8) Drawing can spring condition 9) Drawing initial slow speed hank  10) Drawing 1 yard cv% 11) Ensuring proper functioning of auto leveller in draw frame. 12) Simplex creel draft if excess. 13) Simplex Top roller dia, pressure and saddle springs condition 14) Optimize Spx break draft 15) Spx bare bobbin size and Cone drum setting belt size 16) Spx bobbin pins condition 17) Sliver splitting at simplex 18) increasing roving TM will give results in higher sensitivity IPI parameters 19) Damaged speed frame bobbins inside & outside which creates long thin faults in classimat 20)Bottom ap...

LOW RKM REASONS BLENDING OF MIXING TO BE ENSURED AND IF NECESSARY TUMBLING TO  BE DONE. TO START WITH SLIGHTLY RICHER MIXING AND BACK TO USUAL MIXING% GRADUALLY. AVOID BYPASSING OF THE BEATERS. CHANGING OF THE CARD LINES TO BE AVOIDED . TO START WITH HIGHER NOIL% AND REDUCE GRADUALLY TO USUAL    IF REQUIRED. SOFT WASTE ADDING TO BE AVOIDED FOR FIRST 3 OR 4 MIXINGS. IN SIMPLEX M/C CHECK THE FOLLOWING     a)FALSE TWISTER CONDITION     b)FLOATING CONDENSER CONDITION.     C)DAMAGE COT/APRON.     d)DEFECTIVE SADDLES.     f)TOP ARM LOAD.     g)PRESSER EYE CONDITION.     h)FLUFF ACCUMULATION ON FLYER HOLE.     i)BOBBIN CLEARANCE VARIATION.     j)CONE DRUM NOISE     k)FEED CAN CONDITION         l)SLIVER SPITING. IN SPINNING M/C CHECK THE FOLLOWING:     a)CRISIS-CROSS ROVING.     b)BOBBIN HOLDER ROTATION.     C)DAMAGE COT/APRON. ...
