Sewing Thread Winding System | Different Types Winding | Precision winding | Parallel winding

Introduction:
A transformer winding in which all the turns are arranged on a bobbin instead of in the form of a disk. Generally used for the high-voltage windings of small transformers.

Different Types of Sewing Thread Winding System

Precision winding:
  • Constant winding ratio
  • Winding angle reduces with increasing diameter
  • No pattern areas
  • Good off-winding characteristics
  • High package density
Step precision or digicone winding:
  • Almost constant winding angle
  • The wind ratio is reduced in steps
  • Combines the advantage of random and precision winding
  • No pattern areas
  • Higher consistent package density
  • Perfect unwinding characteristics
  • Straight sided packages
Random winding:
  • Winding angle is kept constant since the winding ratio reduces with increasing diameter
  • Stable packages
  • Even density
Pineapple winding:
  • Winding traverse reduces to produce packages with tapered edges
  • Required for filament winding operations
  • All three types of winding applicable
Parallel winding:
  • Very high package density
  • Thread vertical to package axis
  • Relatively short lengths of thread
  • Suitable for side unwinding
  • No pattern areas 5,6
Ball winding:
  • Very easy unwinding
  • Winding takes place in 4 stages:
  1. Rough base winding
  2. Form winding
  3. Surface layer winding
  4. Circumferencial winding
Skein winding:
  • Easy unwinding
  • Very small parallel strand of soft twisted thread.
