10) Graphic bar indicating the shift in one of the two directions with respect to the optimum condition
(*) K is a constant value added in one direction and subtracted in the other direction. This is due to the
fact that in one of the two directions, besides the yarn used for the actual manufacturing process, an
extra amount of yarn is consumed, as the carriage moves away from the position where the
ULTRAFEEDER/ROLLING FEEDER/UNIFEEDER device is mounted; in the other direction, i.e. during
the carriage approach movement, the machine uses the amount of yarn already drawn in the previous
movement.
Setting the KL and KR values.
Click on the rotary selector to select KL or KR setting
field (according to the installation position of
ULTRAFEEDER/ROLLING FEEDER/UNIFEEDER
device).
