Hint:

Follow the material transformation in a spinning mill: Bale \(\rightarrow\) Blow Room \(\rightarrow\) Lap \(\rightarrow\) Card \(\rightarrow\) Sliver \(\rightarrow\) Draw Frame \(\rightarrow\) Sliver \(\rightarrow\) Speed Frame \(\rightarrow\) Roving \(\rightarrow\) Ring Frame \(\rightarrow\) Yarn.

Answer 1

The Correct Option is C

Step 1: Identify the input or output material for each machine in the spinning process.
- A. Blow room: The blow room line opens and cleans baled cotton. Its final product is typically a lap (a rolled sheet of fibers) or it can feed directly to the carding machine (chute feed). Lap is the correct product form listed.
- B. Carding: The carding machine takes the lap (or tufts from a chute feed) and produces a sliver, which is a thick, untwisted rope of fibers.
- C. Speed frame (Simplex): The speed frame takes the sliver from the draw frame and drafts it to produce a thinner strand called roving, which has a slight protective twist.
- D. Ring frame: The ring frame is the final spinning machine. It takes the roving as its input and drafts and twists it to produce the final product, yarn.

Step 2: Assemble the correct matches.
- A (Blow room) \(\rightarrow\) III (Lap) - B (Carding) \(\rightarrow\) I (Sliver) - C (Speed frame) \(\rightarrow\) IV (Roving) - D (Ring frame) \(\rightarrow\) II (Yarn)

Step 3: Find the corresponding option. The combination A-III, B-I, C-IV, D-II matches option (C).
