True
False

Question 2: Which of the following components is traversed through maximum distance in a ring frame?

Lappet rail
Spindle rail
Ring rail
BCR rail

Question 3: The end breakage is maximum within a chase length when

The ring rail is at the bottom most position
The ring rail is moving up
The yarn tension is maximum
The ring rail is moving down

Question 4: The zone where the yarn is weakest in the spinning zone is

The zone between ring and the bobbin
The zone between the lappet and ring
The zone between the delivery drafting roller and the lappet
Yarn already wound on the bobbin

Question 5: The purpose of having round cop bottom is

To facilitate smooth unwinding of coils without slough off
To increase the cop content
To have higher spindle speed
To have better grip of the bobbin with the spindle

Question 6: Usually the spindle speed is kept at maximum while winding happens in

Top of the spindle
Bottom of the spindle
Middle of the spindle
Both middle and top portions of the spindle

Question 7: Within one chase length, the tension in the yarn balloon is minimum when the winding happens in

The neck (top) of the chase
The shoulder (bottom) of the chase
When the ring rail is moving up
When the ring rail is moving down

Question 8: The most critical aspect in ring spinning which limits the spindle speed is

The drafting system
The overhead cleaning system
The builder mechanism
The ring and traveler system

Question 9: The reason for using different ‘spacers’ in the ring frame is

To change the spacing between the neighboring rovings
To accommodate different twists in the twisting system
To accommodate different thicknesses of fibre strands in the drafting system
To change the spacing between different drafting rollers

Question 10: Traversing of the fibrous strand during roller drafting helps in

Improving the drafting behavior of the fibres
Reducing the wear of the drafting rollers
Improving the twist insertion in the yarns
Reducing the end breakage rate during spinning.
