Question

Which of the following type of action occurs between inclined spiked lattice and evener?

• A. Beat out
• B. Combing
• C. Tearing up
• D. Picking part

Hint:

• Inclined spiked lattice Lifts fiber tufts.
• Evener roller Regulates feed and performs initial opening.
• The interaction between these two spiked surfaces results in larger tufts being pulled apart, which is a "tearing up" or plucking action.
• "Beat out" refers to high-speed impact (beaters). "Combing" is a finer parallelizing action. "Picking part" is too general.

Answer 1

The Correct Option is C

To solve this problem, we need to understand what kind of mechanical action takes place between the inclined spiked lattice and the evener in the cotton blowroom process.

1. Understanding the Components:

Inclined Spiked Lattice: This part of a blowroom machine is designed to transport and open up cotton tufts using spikes on a moving inclined surface.
Evener: It helps regulate the material flow and even out the fiber feed to ensure uniformity before further processing (e.g., scutching).

2. Nature of the Action:

As the cotton moves between the inclined spiked lattice and the evener, the fiber mass is mechanically pulled and broken up into smaller pieces. This process is relatively harsh and involves applying force to separate fiber clusters — known as a tearing up action.

3. Explanation of Options:

• Beat out: Involves impact or hammering action — not relevant here.
• Combing: Refers to fiber alignment and short fiber removal — happens later in the process.
• Tearing up (Correct Answer): This describes the harsh mechanical separation of fibers between the spiked lattice and the evener.
• Picking part: Typically associated with lifting or parting tufts — not the main action here.

Final Answer:

Option C: Tearing up is the correct action that occurs between the inclined spiked lattice and the evener.
