Experiment Name: Study on gearing diagram and production calculation of pirn winding machine.




Objective of the experiment:

  • To know about different parts an drives used in pirn winding machine.
  • Calculate the production of pirn winding machine.
  • Draw a simple diagram of pirn winding machine.
  • Make a short report basis on this experiment.

Parts and drives:
I)       Motor 960 RPM.
II)      Motor pulley.
III)    V –belt.
IV)    Machine pulley.
V)     Intermediate pulley.
VI)   Spandle pulley.
VII)  Bearing tensional.
VIII) Pirn package.








Production Calculation:
Motor R.P.M = 960
Motor pulley dia = 3”
Spandle pulley dia = 1.5”
Pirn head surface = 2.5”
Pirn tail surface = 1.5”
Pirn average surface = 2”

RPM of spandle = 960 X 3/1.5
                             = 1920 R.P.M
Yarn winding = 2 X 1920
                         = 3840 inch / minute
                         = 106.67 yds/minute
                         = 106.67 X 60 = 6400.2 yds/ Hour
                 = 6400.2 X 8 = 51201.6 Yds/ Shift
My machine capacity is 20 spandle winding at a time
51201.6 X 20 = 1024032 Yds / Shift


Result:  1024032 Yds / Shift


Conclusion: By doing this experiment we have learnt about production calculation of pirn winding machine.
