2. END BREAKAGE AT RING FRAME
CAUSES AND SOLUTION

3. INTRODUCTION
 IN RING SPINNING, THE END BREAKAGE OCCURS DUE TO
THE IMBALANCE IN THE TENSION IMPOSED ON THE YARN
AND THE YARN STRENGTH AT THE WEAKEST PORTION
THEREFORE, AN END WILL BREAK WHEN THE SPINNING
TENSION EXCEEDS THE STRENGTH OF THE WEAKEST
PORTION OF THE YARN IN THE SPINNING ZONE

4. RING FRAME MACHINE
RING SPINNING IS A METHOD OF SPINNING FIBRES, SUCH AS
COTTON, FLAX OR WOOL, TO MAKE A YARN. THE RING FRAME
DEVELOPED FROM THE THROSTLE FRAME, WHICH IN ITS TURN
WAS A DESCENDANT OF ARKWRIGHT'S WATER FRAME. RING
SPINNING IS A CONTINUOUS PROCESS, UNLIKE MULE SPINNING
WHICH USES AN INTERMITTENT ACTION.

5. YARN PASSAGE IN RING FRAME

6. OBJECT OF RING FRAME
 CREELING
 TO PRODUSE REQUIRED COUNT OF YARN
 TO INSERT SUFFICIENT AMOUNT OF TWIST
 TO WIND THE YARN ONTO THE BOBBIN
 TO BUILD THE YARN PACKAGE PROPERLY
 DOFFING OF BOBBINS

7. STARTUP BREAKAGE IN RING FRAME
 START UP BREAKAGE ARE ONE OF THE DISTURBING
ELEMENTS IN DECREASING THE EFFICIENCY OF RING
SPINNING MACHINE.
 IT HAPPENS AFTER STARTING THE MACHINE AND AFTER
EVERY DOFFING.
 IT CAN BE DEFINED AS NUMBER OF THREAD BROKEN UP BY
THE MACHINE AT STARTUP .

8. REASONS FOR START UP BREAKAGE
 DEALY DRAFT TIMING.
 FAN ON DEALY TIMING.
 BACK WINDING.
 UNDER WINDING.
 LAPPET WINDING.
 WORKERS DOFFING PRACTICE.
 START SPEED.

9. SOME OTHER REASONS OF BREAKAGE
IN RING FRAME
 SUCTION NOT PROPER.
 MESHING OF GEAR NOT PROPER.
 UNDRAFTED MATERIAL.
 TRAVELLER JAMMED WITH FLY etc.
 UNSUITABLE TRAVELLER TYPE.
 UNEVEN SPINNING TENSION.
 SPINDLE SPEED TOO HIGH,YARN STERENTH INSUFFICIENT.
 TOO LONG RUNNING TIME OF TRAVELLER.

10.  POOR CONDITION OF RING.
 BALLON STABILITY TOO SLOWLY BUILT UP.
 BECAUSE OF REASONS SUCH AS SLUBS, FOREIGN PARTICLE
etc.
 POOR MACHINERY AND IMPROPER CLEANING OF
MACHINERY.
 HIGH CURLING TENDENCY OF THE YARN.
 CLIMATE CONDITION NOT OPTIMUM.

11.  IMPROPER ABC RING SETTING.
 BUFFING COTS.
 SPINDLE EYE MISSING.
 IMPROPER DRAFTING LOAD.
 HIGH VARIATION IN ROVING.
 RELATIVE HUMIDITY AND TEMPERATURE VARIATION.
 HARDNESS OF COTS.
 BOTTOM AND TOP APRON QUALITY.
 HIGH NEPS.

12. HOW TO MEASURE START UP BREAKAGE
 WHEN A DOFF COMPLETS, THE LAPPET RAIL IS MOVED BACK
AND IT BECAMES EASY FOR THE WORKERS TO DOFF THE
COMPLETE BOBBINS AND REPLACE IT WITH THE EMPTY
ONES.
 NOW THE MACHINE IS PUSHED ON AND THE LAPPET RAIL
AGAIN COMES BACK TO ITS ORIGINAL [HORIZONTAL]
POSITION

13.  AND NOW THE MACHINE IS STOPPED MEANS NO WINDING
OF YARN IS ALLOWED TO BE MADE ON THE EMPTY BOBBINS
AND WE COUNT THE NUMBER OF ENDS DOWN FROM BOTH
SIDES OF THE MACHINES i.e. LEFT AND RIGHT
 NOW WE ALLOW THE MACHINE TO RUN FOR A MOMENT AND
THEN AGAIN WE COUNT THE ENDS DOWN BEING DONE BY
THE MACHINE AND WE GET START-UP BREAKAGE FOR EACH
AND EVERY MACHINE.

14. MATHEMATICAL EQUATION TO
CALCULATE STARTUP BREAKAGE.
 NO. OF ENDS DOWN BEFORE STARTING OF M/C AT DOFF= H
 NO. OF ENDS DOWN AFTER STARTING OF M/C = G
START UP BREAKAGE PERCENTAGE = [ H – G]*100/1200
WHERE,
(1200 IS TOTAL NO OF SPINDLE.)

15. SOLUTION AND SUGGESTIONS
 CHANGE THE TRAVELLER PERIODICALLY GENETALLY AFTER
2-3 DAYS.
 RING IS CHANGED AFTER 1 OR 2 YEARS, WHEN RING IS
CHANGED THERE SHOULD BE NO IDLE SPINDLE IN THE RING
FRAME MACHINE.
 TRY ANOTHER TRAVELLER FORM OF PROFILE.
 INCREASE YARN TWIST OR REDUSE SPINDLE SPEED.
 CHECK RAW MATERIAL COMPOSITION.
 POOR CONDITION OF RINGS.

16.  POOR CENTERING OF RINGS.
 INCREASE DRAFTING SYSTEMS START UP DELAY.
 MAINTAIN START SPEED, INITIAL SPEED.
 LONG SNARLING SETTING (UP AND DOWN) SHOULD BE
OPTIMUM.
 BREAK PRESSURE SHOULD BE OPTIMUM (1.5 – 2 Kg).
 CHECK RAW MATERIAL COMPOSITION.
 OPTIMIZE CLIMATE, ADJUST BLOWER NOZZLES.

17. EFFECTS OF END BREAKAGE IN RING
FRAME
 PROCUCTION DEALY AND EFFICIENCY LOSS.
 COST INCREASES DUE TO BREAKAGE.
 POWER CONSUMPTION.
 IDLE RUNNING SPINDLE.
 TIME CONSUMPTION.
 HARD, KNEUMAFILE WASTE INCREASES.
 YARN QUALITY GET AFFECTED.
 FLY , DUST , SWEEPING INCREASED.

18. BREAKAGE DUE TO SPINDLE.
 LACK OF LUBRICATION IN
THE BOLSTER CAGE OR
INSERT.
 BENT SPINDLE IS OUT OF
CENTRE OF THE SPINDLE.
 EXCESSIVE SPINDLE SPEED
THAN REQUIRES FOR THE
COUNT.

19. BREAKAGE DUE TO BOBBIN.
 TOO LARGE OR SMALL
DIAMETER OF BOBBIN
THAN THAT SUITABLE FOR
THE COUNT.
 JUMBLING BOBBIN.
 VIBRATING BOBBIN.
 BADLY WORN BOBBIN IN
WHICH YARN TENDS TO
CATCH AT THE STARTING
UP.

20. BREAKAGE DUE TO DRAFTING ZONE
 INSUFFICIENT BREAK
DRAFT.
 WORN APRON.
 WORN OR GROOVED
ROLLER.
 ROLLER LAPPING.
 INCORRECT WEIGHT
DISTRIBUTION ON TOP
ROLLER.

21. BREAKAGE DUE TO TAPES
 BAD JOINING OF TAPES
CAUSING VIBRATION.
 TAP ENDS FLYING OFF DUE
TO BADLY SEWING.
 SLIPPING TAPES.

22. BREAKAGE DUE TO LAPPET RAIL
 INCORRECT SETTING OF
THE LAPPET IS NOT AT THE
STRAIGHT LINE WITH THE
TOP OF THE SPINDLE.
 STARTING UP OF THE
MACHINE WHEN THE
LAPPET RAIL IS AT THE TOP
POSITION.

23. BREAKAGE DUE TO TRAVELLER
 HEAVY OR LIGHTER
TRAVELLER THAN THAT
REQUIRED FOR THE
COUNT.
 WORN TRAVELLER.
 TRAVELLER FLYING OFF.

24. BREAKAGE DUE TO RING
 WORN RING.
 GREASE OR GUM ON AND
UNDER SIDE OF THE RING
FLANGE.

25. BREAKAGE DUE TO ROVING
 BAD PIECING IN ROVING.
 STRETCHED ROVING.
 IRREGULAR ROVING.
 MORE WASTE IN ROVING

26. BREAKAGE DUE TO IMPROPER RELATIVE
HUMIDITY IN SPINNING DEPARTMENT
 THE RELATIVE HUMIDITY
MUST BE PROPER AS PER
THE REQUIREMENT WHILE
PROCESSING MAN MADE
AND NATURAL FIBER.

27. BREAKAGE DUE TO TEMPERATURE
 TEMPERATURE MUST BE
OPTIMUM WHILE
PROCESSING NATURAL
FIBER.

28. BREAKAGE POINTS
 C- SHAPED TRAVELLER.
 SPINDLE BELT.
 LAPPET GUIDE.
 RING RAIL.
 RING
 BOBBIN

29. CONCLUSION
 FIRST OF ALL WE SHOULD CHECK ROVING FRAME BEFORE
FEEDING IT AT RING FRAME.
 PROPER CREELING MUST BE DONE.
 DRAFING ARRANGEMENT MUST BE PROPER AND BREAKE
DRAFT MUST ALWAYS MINIMUM.
 APRON AND COTS SHOULD BE IN GOOD CONDITION.
 PRESSURE ON TOP ROLLERS SHOULD BE OPTIMUM.

30. CONCLUSION
 TEMPERATURE AND RELATIVE HUMIDITY MUST BE SET AS
PER REQUIREMENT.
 SPINNDLE SHOULD BE IN THE CENTRE ALONG WITH RING
AND COP.
 RING FRAME MACHINE SHOULD HAVE PROPER MAINTANECE
AND TIME TO TIME OILING AND GREECING SHOULD BE DONE
 OVERALL BREAKAGE POINTS MUST PROPERLY CHECHKED
BEFORE STARTING THE MACHINE.
