Simplex Machine for Spinning Process

Simplex Machine for spinning process is an industrial machinery used for spinning process of Textile technology to transform the drawn sliver into roving. The main function of simplex machine is the attenuation of drawn sliver and insert small amount of twist to give required strength of roving. Finally, the twisted roving is wound on to bobbin. Simplex machine is used to the carded and combed yarn process but for the rotor spinning system this process can be eliminated.

Functions of this Spinning Machines

  • Drafting: The main task of the spinning machines to attenuation of the sliver to required count of the roving.
  • Twisting: To hold it together, small amount of twist is inserted. The numbers of twist is very low.
  • Winding: To easily transport the twisted roving, it winds onto the bobbin  developed by textile machine manufacturers

Recent Developments of Simplex Machine

  • Higher flyer speed: maximum 2000rpm. 1000~1500rpm is commonly used.
  • Improved drafting system: for example, SKF PK1500 and SKF PK1600. Apron drafting, better control of fibre and draft range 4-20.
  • Improved flyer design
  • Higher flyer speed: up to 1500 rpm
  • Plastic flyer: Light in weight, enables higher flyer speed and less power consumption.
  • Top mounted flyer
  • No spindle is used; flyer gets drives from the top.
  • Suction unit in the drafting zone.
  • Data collection system.
  • Automatic Tension Control device(ATC)
  • Improved building mechanism
  • Higher content of roving
  • Sliver stop motion
  • Roving stop motion
  • Separate flyer and bobbin drive
  • Over Headed Traveling cleaner(OHTC) is used
  • Speed profile
  • Desired doff length can be achieved
  • False twister
  • Equal angle of roving
  • Computerized monitor
  • Inching motion
  • Gearing in the oil bath for smooth running of the machine and high production.

Simplex Machine for Simplex Filler

  • This simplex filler machine is to transform the sliver coming from draw frame into roving for textile production
  • The main operation of the machine involved creeling, drafting, twisting, winding, building and doffing.
  • Entering sliver counts of 0.12 Ne to 0.24 Ne and counts of the delivered roving of 0.27 Ne to 3Ne.
  • The number of revolutions of the spindle is maximum value of 1500r.p.m. for textile production
  • Drafting system stretches draw frame sliver and make it thin using modern textile technology
