Question

During yarn formation on the ring frame, the cotton material passes through:
A. back roller
B. ring bobbin
C. delivery roller
D. traveller
E. lappet guide Choose the correct answer from the options given below :

• A. A, C, E, B, D
• B. A, C, E, D, B
• C. A, C, D, E, B
• D. A, C, B, D, E

Hint:

The Traveller (D) is the tiny component that does all the hard work—it inserts the twist and controls the winding onto the Bobbin (B).

Answer 1

The Correct Option is B

Concept: The ring frame drafting and twisting zone has a very specific mechanical path for the fiber strand.

Step 1: The Drafting Zone.
Roving enters the drafting system at the A (Back roller). It is thinned out as it moves toward the front, leaving the system at the C (Delivery roller).

Step 2: Twisting and Guiding.
The thinned strand passes through the E (Lappet guide) (also called the thread guide) which centers the yarn above the spindle.

Step 3: Winding.
The yarn then passes through the D (Traveller), which rotates around the ring to insert twist, and is finally wound onto the B (Ring bobbin).
