Question

The drive for the feed lattice in Mixing Bale Opener is

• A. Continuous
• B. Intermittent
• C. Interruptive
• D. Higher

Hint:

Feed lattices in blowroom machines operate with intermittent motion to ensure controlled fibre feed and uniform opening.

Answer 1

The Correct Option is B

Concept: In a Mixing Bale Opener, the feed lattice is responsible for transporting compressed cotton layers from the bale feed zone towards the opening unit. Since the bale laydown must be controlled and uniform, the feed is not allowed to move at a constant continuous rate. Instead, the feed is regulated in steps so that controlled layers of cotton are presented to the opening rollers. This ensures proper opening, blending, and avoids overloading of the machine.

Step 1: Understand the function of feed lattice.
The feed lattice carries cotton from bales in a controlled manner to ensure uniform feeding. \[ \text{Feed lattice} \Rightarrow \text{Controlled delivery of cotton layers} \]

Step 2: Analyze type of motion required.
For proper blending and opening:
• Continuous motion would cause uneven feeding
• Controlled stepwise feeding is required Hence, the system uses intermittent drive.

Step 3: Relate mechanism with production control.
Intermittent motion ensures: \[ \begin{aligned} &\bullet \text{Uniform bale opening} &\bullet \text{Controlled fibre tufts} &\bullet \text{Avoids overfeeding} \end{aligned} \]

Step 4: Final answer selection.
Therefore, the drive of feed lattice in Mixing Bale Opener is: \[ \boxed{\text{Intermittent}} \] So, \[ \boxed{\text{Option (B) is correct.}} \]
