Calculation of Draft, Draft Constant of Ring Frame

2) To find out draft of each zone of the ring frame.

M/C specifications:

• RPM of the motor =1440


• Dia of the motor pulley = 5”


• Dia of the tin cylinder pulley = 10.5”


• Dia of the tin cylinder = 10”


• Dia of the wharve = 1.125”


• No of teeth of fibre wheel = 42T


• No of teeth of front roller driving wheel = 98T


• Dia of the front roller = 1”
