Step 1: Recall loom parts.
- The reed is a comb-like device made of metal strips fixed in a frame.
- It is positioned between the heddles and the cloth beam.
Step 2: Functions of the reed.
The reed performs three functions:
1. It pushes the weft yarn into place after each pick.
2. It maintains warp yarn spacing.
3. It guides the shuttle carrying weft across the loom.
Step 3: Option analysis.
- (A) Reed: Correct, comb-like device controlling yarn spacing.
- (B) Warp: Refers to lengthwise yarns, not a device.
- (C) Shuttle: Device carrying weft yarn, not comb-like.
- (D) Lease Rods: Maintain warp order, but not comb-like.
Step 4: Conclusion.
Therefore, the comb-like device described is the Reed.
