Useful Hints when using the ULTRAFEEDER device on socks or
pantyhose production machines
ƒ It is advisable to insert the thread guide when the speed is lower than 200 rpm
(the higher the yarn title, the higher can be the insertion machine speed).
ƒ It is advisable to exclude the thread guide when the machine speed reaches
about 200 rpm.
ƒ
During the thread guide insertion/exclusion operation it is advisable to use
acceleration/deceleration ramps on machine speed.
ƒ If, using very thin or soft yarns, you experience frequent yarn breakage during
machine stop and restart phases with ULTRAFEEDER running, prior to start
the machine at the maximum speed, it is advisable to perform 2/3 revs at test
(or
jog) speed, in order to extend the yarn, so that possible yarn over-feedings in the
machine stop phase will be eliminated.
Even if the torque of motor driving the roller rotation is very low and does not
involve hazards for the operator safety, it’s always advisable to lock the motor
prior to operate on KTF/100HPS devices (yarn threading, tilt adjustment of
coil separation device, etc.) in order to avoid unexpected motor start-up
events.
To lock the motor, just press the C button and check that the STOP
red LED (front) turns-on.
At the end of the manual operation press again + and check that the STOP red
LED (front) turn-off.
