Concept:
In modern comber machines, the web formation and delivery system plays a crucial role in productivity and sliver quality. The half-moon shaped web is designed to improve continuity of fibre transfer and reduce interruptions during detaching and feeding.
This improves machine efficiency and results in higher production rates.
Step 1: Understand half-moon web function.
Half-moon web improves fibre flow from nippers to detaching rollers.
\[
\text{Improved fibre continuity} \Rightarrow \text{Higher efficiency}
\]
Step 2: Analyze effect on production.
With better web control:
• Reduced fibre breakage during transfer
• Faster and smoother delivery
• Reduced machine stoppages
\[
\text{Result: Increased production (HOK)}
\]
Step 3: Evaluate other options.
• Low U% → quality improvement, not primary function
• High U% → incorrect
• High bulk → not related to web shape
Step 4: Final answer selection.
Thus,
\[
\boxed{\text{High Production in terms of HOK}}
\]
So,
\[
\boxed{\text{Option (A) is correct.}}
\]
