Slip Draft Spinning Frame Machine | Jute Slip Draft Spinning FrameMachine

Experiment Name: Study on the Jute Slip Draft Spinning frame machine.

Objects:
1. To know about gearing diagram of the M/C.
2. To know about Flyer speed.
3. To know about surface speed of drawing, retaining r/r and Tin cylinder.

Main Parts:
§ Retaining roller.
§ Intermediate roller.
§ Drawing roller.
§ Tin cylinder.
§ Flyer.
§ Bobbin rail.

General Description:

• Machine manufacturer = JAMES MACKIE AND SONS.
• Model number = 14376.
• No of flyer per frame = 20 
• Draft range = 10-20 
• Machine pitch = 4.25²
• Flyer speed = 3000-4000 rpm.

Machine Specification:
o Motor rpm = 1450.
o Motor pulley diameter = 8.5²
o Machine pulley diameter = 11²
o Tin cylinder diameter = 6²
o Flyer diameter = 2²
o TCP = 50T
o DCP = 46T
o Drawing roller diameter =2.25²

 Result:
o Flyer speed = 13361.36
o Surface speed of Tin cylinder =  121120.07”/min
o Surface speed of drawing r/r =  910.35”/min
o Surface speed of retaining r/r =  64.42”/min
o Surface speed of intermediate r/r =  83.3”/min
o Draft =14.13
o Draft constant = 650

Conclusion: 

This experiment is very important for us to know and learn about the slip drafting sliver spinning frame. So, we should learn about this experiment very carefully and sincerely.
