Updated: Dec 22, 2023

Q. Compare between ordinary & automatic shuttle.


S. No.

Automatic shuttle

Ordinary shuttle


There is no spindle.

There is a spindle.


Threading is done automatically.

Threading is done normally.


Three metallic rings are present in this shuttle.

Ordinary pirn is used.


Automatic pirn is used

Ordinary pirn is used.


Fixing of pirn in the shuttle is done automatically.

Fixing of pirn in the shuttle is done ordinarily.

Q. State the Importance or Effects of tensioning Device.


Too high tension:

  • Can damage the yarn.

  • The breakage rate may be greater.

  • Elongation properties may change.

Too low tension:

  • Can lead to unstable or loose packages which will not unwind cleanly.

  • Variation in yarn tension in different parts of a wound package can cause undesirable effects.

For MMF:

Too high tension:-

  • Can cause molecular change which affects dyeability.

  • Random variation in color shading.

For Staple or Spun yarn:

Too high tension:-

  • May breakage at a thin place

Q. Differentiate between cone winding & cheese winding.


S. No.

Cone winding

Cheese winding


It is a conical package.

It is a parallel package.


The traversing system of cone winding m/c is rotating.

The traversing system of cheese or spool winding m/c is reciprocating.


Package rotate with surface contact & variable speed.

Package rotate with surface contact or variable speed.


It is used largely

It is used less than cone winding


It is used in weft insertion of shuttleless loom

It does not use


Cone is used in warping m/c

Cheese/spool is used in the warping process.


Cone is used in knitting m/c.

Cheese or spool does not use in knitting m/c.

Q. What are the requirements of a tensioning device? Write down the factors that influence fore selection for tensioner?



  1. The device must be reliable to control uniformly in tension.

  2. It must be easily threadable.

  3. It must neither introduce nor magnify tension variation.

  4. It must not introduce differences in a twist.

  5. It must not be affected by wear.

  6. It must not easily adjustable.

  7. It must not be affected by the presence of oil and dirt.

  8. It must not encourage the collection of dirt and dust.

  9. It must be capable of easy cleaning.

  10. The operating surface must be smooth.

  11. It must be inexpensive or cheap.

  12. It must be simple in design & operation.

  13. It must not cause damage to the yarn.

Q. What is winding efficiency?


It is the percentage expression of the ratio of actual production & calculated production.
