Experiment Name : Study on middle and back roller of ring
frame machine.
Introduction: Middle and Back roller operated in drafting
zone of a ring frame machine. Th objective of that two roller is to draft the
roving to convert into yarn.
Objective:
1) To learn about gearing of back roller.
2) To learn about gearing of middle roller.
3) To calculate those roller speed.
Figure:
Calculation:
Speed of middle roller =
(131 X 20 X 23 X 40 X 33 X 63 X 81) / (80 X 77 X 81 X 63 X
81 X 26) [131 = front roller speed]
= 6.131
Speed of back roller
(131 X 20 X 23 X 40 X 22 X 60 X 69) / (80 X 77 X 81 X 60 X
69 X 23) [131 = front roller speed]
= 4.62
Result :
Speed of Middle roller = 6.131
Speed of Back Roller = 4.62
