Slip Draft Spinning Frame Machine | Jute Slip Draft Spinning Frame Machine

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:
  • Motor rpm = 1450.
  • Motor pulley diameter = 8.5²
  • Machine pulley diameter = 11²
  • Tin cylinder diameter = 6²
  • Flyer diameter = 2²
  • TCP = 50T
  • DCP = 46T
  • Drawing roller diameter =2.25²
  • Retaining roller diameter = 2.5²
  • Intermediate roller diameter = 1.375².
Calculations: 

Fig: Gearing diagram of Jute Slip Draft Spinning Frame Machine
 Result:
  • Flyer speed = 13361.36
  • Surface speed of Tin cylinder =  121120.07"/min
  • Surface speed of drawing r/r =  910.35"/min
  • Surface speed of retaining r/r =  64.42"/min
  • Surface speed of intermediate r/r =  83.3"/min
  • Draft =14.13
  • 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.
