SPIN PLAN OF SPINNING LINE

A. Auto Cone:

 Delivery speed (mtr/min) x 1.0936 x 60 x 24 x no.spindles x eff.%
Production = ----------------------------------------------
                                           840 x count x 100

               
                   1000 x 1.0936 x 60 x 24 x 60 x 0.72

 Production = ---------------------------------------------
                                840 x 40 x 100

Where,
Delivery speed = 1000,
No. of spindle = 60,

Production = 24.30 bags/day/auto cone
No of auto cones require = ring production/production of one auto cone

No of auto cones require = 265/24.30 = 10


B. Ring:
  Avg. Spindle speed x 60 x No.of Spindles x 24 x Eff.%
Production = -----------------------------------------------
                        T.P.I x 36 x 840 x Count x 100

                              19,000x 60 x 480 x 24 x0.92
Production = -------------------------------------------
                             19.60 x 36 x 840 x 40 x 100
Where,
Delivery speed = 19000
No. of spindle = 480,
TPI = 19.60,
Count= 40,


 Production    = 5.09 bags/day/frame
                          =5.09x52
                         = 265 bags/52 frames
                                           
C.  SIMPLEX:

Ring consumption = 265x (100/100-waste)
Ring consumption = 265x (100/100-3)
Ring consumption = 273 bags

H.R =1.20 TM = 0.757 T.P.I = 0.829

                   Avg. Spindle speed x 60 x No. Of.                             Spindle x 24 x Eff%
Production = -----------------------------------------------
                         T.P.I x 36 x 840 x Count.

                       1100 x60 x120 x 24 x 0.85
Production = --------------------------------------
                       0.829 x 36 x 840 x 1.20 x 100


Production = 53.70 bags/day/frame
No of simplex frame require = ring consumption/production of one simplex frame
No of simplex require=273/53.70
No of simplex require= 5 simplex

D. Finisher Drawing:

Simplex consumption: 273x (100/100-2)
Simplex consumption: 278.57bags

                      Speed (mtr/min) x 1.0936 x 60 x                             24 x 70 x 0.85(efficiency)
Production = -----------------------------------------------
                                           7000 x 100

                   400 x 1.0936 x 60 x 24 x 70 x 0.85
 Production   = ------------------------------------------
                                         7000 x 100

                         = 54.53bags/day/drawing

No of drawings require = simplex consumption/production of one drawing
No of drawings require=278.57/54.53
No of simplex require= 5

E. Breaker Drawing:

Finisher consumption: 278.57bags

                     Speed (mtr/min) x 1.0936 x 60 x.                     24 x 70 x 0.75(effi)
Production = -----------------------------------------------
                                                7000 x 100
                     300 x 1.0936 x 60 x 24 x 70 x 0.75
                     = ------------------------------------------
                                               7000 x 100

                     = 35.43bags/day per single hand
                     = 70.68 bags (double delivery)

No of drawings require = finisher consumption/production of one drawing
No of drawings require=278.57/70.68
No of drawings require= 4

Polyester % = 278.57 x 0.52 = 144.85 bags
Cotton % = 278.57 x 0.48 = 133.71 bags

Card :( polyester)
B. Drawframe  consumption: 144.85bags

             Delivery speed (mtr/min) x                           1.0936 x 60 x 24 x 70(grains/yrd) * xn%
Production = -----------------------------------------------
                              7000 x 100

                   150 x 1.0936 x 60 x 24 x 67
Production = ------------------------------------ X 0.80
                                7000 x 100

                            = 18.89 bags/day/card
No of cards require = B.Drawframe consumption/production of one card

No of cards =144.85/18.89
No of cards = 8
