Question

In \(\underline{\hspace{2cm}}\) rapier, the gripper heads are propelled by flexible tape.

• A. Telescopic
• B. Double bonded rigid
• C. Flexible
• D. Single head rigid

Hint:

The key difference between rapier types is how they are stored outside the shed: - Rigid Rapier: Needs large side housing for the rigid rod. - Flexible Rapier: The flexible tape coils up, saving space.

Answer 1

The Correct Option is C

Step 1: Understand the function of a rapier in a loom. A rapier is a device used to carry the weft yarn across the shed. It can be rigid or flexible.

Step 2: Differentiate between rigid and flexible rapiers.
- Rigid Rapier: Uses a solid, rigid rod to carry the weft. These require a large amount of floor space on either side of the loom to house the rapier when it is withdrawn from the shed. Examples include single rigid and double rigid rapiers. Telescopic rapiers are a type of rigid rapier that retracts into itself to save space.
- Flexible Rapier: Uses a flexible tape or band to carry the gripper head. This tape can be coiled into a housing when it exits the shed, which significantly reduces the machine's width and floor space requirement compared to a rigid rapier system.

Step 3: Match the description to the type. The description "propelled by flexible tape" directly defines the mechanism of a flexible rapier loom.
