Question

Parallel Close winding is observed in the following winding principle

• A. Plane
• B. Precision
• C. Cross winding
• D. Drum

Hint:

Precision winding produces compact parallel close wound packages with uniform coil geometry.

Answer 1

The Correct Option is B

Concept: Winding systems are classified based on package formation and yarn laying pattern. In precision winding, the winding ratio between spindle and drum is kept constant, resulting in closely packed parallel layers of yarn. This produces a compact and stable package structure known as parallel close winding.

Step 1: Understand winding types.
Precision winding maintains controlled coil placement. \[ \text{Constant winding ratio} \Rightarrow \text{Uniform coil spacing} \]

Step 2: Identify package structure.
Precision winding produces:
• Parallel yarn layers
• Close packing
• Stable cone structure

Step 3: Compare options.

• Drum winding → random coil formation
• Cross winding → criss-cross pattern
• Plane winding → not standard industrial classification

Step 4: Final answer selection.
Thus, \[ \boxed{\text{Precision winding}} \] Therefore, \[ \boxed{\text{Option (B) is correct.}} \]
