Amongst the following, the correct sequence of drives from main shaft to bobbins in a roving frame is
Show Hint
In roving frames, cone drums regulate variable speed transmission to bobbins, and planetary gears adjust bobbin speed relative to flyer.

- Main shaft → Twist change gears → Cone drums → Planetary gears → Bobbins
- Main shaft → Draft change gears → Cone drums → Planetary gears → Bobbins
- Main shaft → Draft change gears → Planetary gears → Cone drums → Bobbins
- Main shaft → Twist change gears → Planetary gears → Cone drums → Bobbins

The Correct Option is A
Solution and Explanation
Understanding drive transmission in a roving frame.
In a roving frame, motion is transmitted in a specific sequence to control draft, twist, and winding on the bobbins. The path for bobbin winding control typically follows:
Main shaft → Twist change gears → Cone drums → Planetary gears → Bobbins. This sequence ensures proper synchronization of twist insertion and bobbin winding as the roving builds up on the bobbin.

- For a textile industry, the revenue of selling \( x \) tons of yarn is \( R(x) = 4x \) and the cost of producing \( x \) tons of yarn is \( C(x) = 10 + 2x + 3x^{2/3} \). The industry decided to calculate the break-even (when revenue is equal to the cost) for \( x \) tons of yarn using the Newton-Raphson method. Assuming the initial break-even of 8 tons, the break-even (in tons) after the first iteration is:
- High drape coefficient of fabric indicates:
