The formula for calculation of reeling character is given below :
9.3. Example for calculaiion of reeling characters
1. Reelabilitypercentage : numberof reelingcocoons X 100
number of feeding end
a. Number of reeling cocoons : testing cocoons - number of unreeled cocoons
- number of carry over conversion cocoons
b. Number of feeding end : measurement of feeding end + number of
carry over cocbons - number of carry over
conversion cocoons.
e.g. Testing cocoons : 300 ; measurement feeding end = 337
Unreeled cocoons : (fully 1, middle 3)
Carry over cocoott5 : (outside26,middle 27, innerside 7) (auto)
Carry over cocootl5 : (outside 10, middle L5, innerside 7) (multi)

number of reeling cocoons
a. 1. Auto-number of : testing cocoons - number of unreeled converreeli--g
cocoons
sion cocoons-(number of carry over conversion
cocoons + increase or decrease number of
cocoons).
2. Multi-number of : testing cocoons - number of unreeled
reeling cocoons
e.g. Testing cocoons : 300 ;
Total length of raw silk = 36,580
Average reeling cocoon number :
conversion cocoons - number of carry
over conversion cocoons.
