Function of positive relaxation device(Plain weave only)

Relationship between opening and relaxation device

If there is no positive relaxation device

Tension is applied to the string when it is opened, but the tension applied to the string is loosened when it is closed.

In such a case, it is not suitable for high-speed weaving.
This is because poor opening is likely to occur.

If there is positive relaxation device

The tension roller is moved back and forth according to the opening operation of the warp. Then, the tension fluctuation of the warp is absorbed.
In such a case, it is suitable for high-speed weaving.
If you do positive relaxation exercises other than plain weave, extra stress will be applied to the warp strings.
