Question:
In a bobbin leading roving frame, the correct relationship between spindle speed and bobbin speed is
In a bobbin leading roving frame, the correct relationship between spindle speed and bobbin speed is
Show Hint
- The bobbin diameter increases as the yarn is wound, causing the spindle speed to decrease with increasing bobbin size.

The Correct Option is C
Solution and Explanation
In a bobbin leading roving frame, the spindle speed decreases as the bobbin diameter increases because the friction between the bobbin and spindle changes with the increase in the bobbin size. The graph that shows this inverse relationship between spindle speed and bobbin speed is option (C).

- In a roving frame, the ratio of the diameter of the top (driver) cone-drum to the diameter of the bottom (driven) cone-drum is inversely proportional to bobbin diameter. At an instant,
Top cone-drum diameter = 212 mm
Bottom cone-drum diameter = 108 mm
Bobbin diameter = 54 mm
When the bobbin diameter becomes 100 mm, the ratio of the top cone-drum diameter to the bottom cone-drum diameter (up to 2 decimal places) is ____________________________________.- GATE TF - 2023
