Classification of Winding Machines

Classification of winding machines based on package, winding, drive, and type of yarn used which are listed below:

  1. According to package:
    • Flanged bobbin winding m/c.
    • Cone winding m/c.
    • Cheese winding m/c.
    • Pirn winding m/c.
    • Cop winding m/c.
  2. According to winding:
    • Precision winding m/c.
    • Non-precision winding m/c.
  3. According to Drive:
    • Direct Drive winding m/c.
    • Indirect Drive winding m/c.
  4. According to the type of yarn used:

For warp yarn:

  • Upright spindle winding m/c.
  • Drum/Cylinder winding m/c.
    • Warp winding m/c
    • cheese winding m/c
    • Spool winding m/c
    • Cone winding m/c

For weft yarn:

  • Pirn winding m/c
    • Ordinary pirn winding m/c
    • Automatic pirn winding m/c
  • Cop winding m/c.

Faults in Winding

Some of the common winding faults and their causes are as follows:-

Fault Description
Yarn breakage The main causes are :

  • Improper slub catcher setting.
  • Incorrect tension level.
  • Improper winding speed.
Faulty Stitch The main causes of faulty formation of stitch :

  • Excessive spindle speed.
  • Worn out spindle speed.
  • Large tension variation during winding.
  • Defective release of Yam after knotting.
  • Improper alignment of tension bracket.
  • Worn out or damaged grooves in the drum
  • Improper setting of traverse restrictions.
Faulty Patterns or Ribbons The main causes of faulty formation of patterns are

  • Defunct antipatterns motion.
  • Incorrectly set antipatterns motion.
  • Cone or choose loose fitting on winding spindle.

 


Entanglements Entanglements are mainly caused due to:-

  • Repeated knotter fiber
  • Strong suction pressure
