P= (L x 1.0936 x 60x effy) / (hank (NeC) x 36 x 840 x 2.2046)

P=Production / hr
L= Delivery speed in m/min
Effy= Efficiency
Ne= English count ( Number of 840 yards in one pound )
840= Constant
2.2046= to convert from lbs to kilograms

1. Production in kgs/ 8 hrs = (0.2836 x L x Efy) / (Ne)

L = Delivery Speed m/min
Effy= Efficiency
Ne = English Hank
(3) production / 8hrs = (Hank x Nd) / (Ne x 2.2046)
Hank= no of hank (840 yards) delivered by the machine
Nd = no. of deliveries
Ne= hank of the material

Draw_frame :

Break draft = surface speed of 2nd roller / surface speed of back roller
Main draft = surface speed of 1st roller / surface speed of 2nd (middle) roller
Total draft = surface speed of delivery roller / surface speed of feed roller

1. Production in kgs / 8 hrs = ( 0.2836 x L x effy x Nd ) / Ne

L = Delivery speed in m/min
Effy = Efficiency
Nd =No of delivery

1. Production in kgs/hrs = (FRD x FR rpm x 3.1416 x 60 x effy x Nd ) / (Ne x 840 x 36 x 2.2046)

FRD = Front Roller Diameter
FR rpm = front roller rpm
Effy = Efficiency
Nd =No of delivery
NeC = Sliver Hank

#Speed_Frame & #Ring_frame ? E.D.B= Sohel

Twist / inch( TPI) = Spindle Speed /FRS
FRS = Front roller surface speed in inches/min
FRS = FR rpm x 3.1416 x FRD
FRS = Front roller surface speed
FRD = Front Roller Diameter in inches
TPI = T.M. x √Count,or,Hank
T.M. = twist multiplier

1. production in kgs / 8 hrs = (7.2 x S.S. x effy ) / (T.P.I. x ne x 1000)

S.S. = Spindle Speed
5. Spindle Speed = m/min x T.P.I. x 39.37
6. Hank delivered = Spindle Speed / (T.P.I. x 62.89)

Ring traveller speed in m/Sec = ( Spindle speed x ring dia in mm x 3.1416) / ( 60 x 1000)

Builder Motion :

New Ratchet Wheel = Present ratchet wheel x √Present hank / new Hank

9. Twist Change Wheel :

New Change wheel = Present wheel x ( √present NeC/New NeC) x ( Present TM/New TM)

Winding/ Autocone ? E.D.B = Hïrå

Yarn Tension weight = 0.571 x Lea Strength in kgs + 1.8
Yarn diameter (mm) = 0.95 ÷ √Count NeC

Production in kgs /8 hrs= (0.2836 x L x effy x Nd ) / (Ne)
L = delivery speed
Effy = Efficiency
Ne = English Count
Nd = No. of Delivery
P= (L x 1.0936 x 60 x effy) / (hank (Ne) x 36 x 840 x 2.2046)
P= production in kg/hr
L= Delivery Speed in m/min

Rotor E.D.B = MàñîK

Twist per Meter = Delivery speed in mtrs per min ÷ rotor rpm
Production in kgs per hr/rotor = (Delivery speed in meters / min x Tex x 60 x Efficiency %)÷1000

(Rotor rpm x Tex x 60 x effy % ) ÷ 1000 x TPM
