- Drum winders
- Precision winders
- Ply winders
- Doubler winder
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
In precision winding, the winding ratio between spindle and drum is kept constant, ensuring a fixed number of coils per layer throughout the bobbin build. This results in uniform package structure and consistent yarn length per layer.
Step 1: Understand constant coil formation.
Constant coil count indicates fixed winding ratio. \[ \text{Constant coils} \Rightarrow \text{Fixed winding ratio} \]
Step 2: Identify winding system.
Precision winders maintain controlled and constant winding geometry.
Step 3: Compare options.
• Drum winders → variable winding
• Ply winders → twisting process
• Doubler winders → yarn doubling
Step 4: Final answer.
\[ \boxed{\text{Precision winders}} \] Thus, \[ \boxed{\text{Option (B) is correct.}} \]
