Study on calculation of draft constant of ring frame machine.

 

Experiment Name: Study on calculation of draft constant of ring frame machine.

Introduction:

Drafting is one of the major operation of ring frame machine. Ring frame contain three pairs of roller called front roller, middle roller, back roller. Draft = Draft Constant / D.C.P

Objective:

1) To learn about draft, draft constant, D.C.P

2) To write a report according this experiment.

Figure:

Calculation:

Draft Constant = (23 X 60 X 81 X 77 X 80 )  / (69 X 22 X 1 X 23 X 20)  =  986

Draft =  Draft Constant / DCP = 986 / 40 = 24.65
