The objects of tensioners are: To control package density. This is

achieved by giving the required tension onthe yarn.

To remove weak places. This is achievedby the amount of tension weight on theyarn. Because of tension weight weak

places are broken while passing throughthe tensioners.

To remove the adhering impurities presentin the yarn.

Yarn tension plays an important role in winding. Too high atension can damage the yarn, whereas too low a tension can leadto unstable packages ("slough off").

There are several requirements which influence the choice of atensioning device, including:

Must be reliable.

It must be easily threaded. It must neither introduce nor magnify tension variations. It must not introduce differences in twist. It must not be affected by wear. It must be easily adjustable. It must not be affected by the presence of oil or dirt.

It must not encourage the collection of dirt and lint. It must be capable or easy cleaning. The operating surfaces must be smooth. It must be inexpensive.
