Typically, we can consider two distinct cases:
Case 1:
- Startup with a higher tension (10 g in the example below)
- Switching to a lower work tension (5 g in the example below) after a given number of meters (after
200 m in the example below).
This condition can be useful to crimp the yarn on the package cone.
Example of parameter setup in the
START METER =
START TENS =
WORK TENS =
INC/DEC METER =
TARGET METER =
Case 2:
- Startup with a lower tension (2 g in the example below)
- Switching to a higher work tension (5 g in the example below) after a given number of meters (after
200 m in the example below).
This condition can be useful when using elastic yarns, to avoid an excessive tension on the yarn during
the startup phase.
Example of parameter setup in the
START METER =
START TENS =
WORK TENS =
INC/DEC METER =
TARGET METER =
In both cases, whenever a position is stopped for more than 3 seconds (for instance after a yarn breakage
condition), the system will resume the
number of meters defined in

The difference with respect to the previous example is that the system is programmed to provide the target
signal when reaching the number of meters setup (position stop, and Target output generation).

This condition can be useful to facilitate the "doffing" operation.
