Trouble Shooting - Corghi PW IW 6 Manual De Uso

Speed too fast for yarn count
➥ Reduce the speed using the IW keypad, remembering that when this is done during winding
operations a minor deformation of the cone may be caused.
Excessive yarn braking
➥ Slacken off pressure on yarn brakes (11-6 fig.9) and, if necessary, use only one, setting the other
one at zero pressure.
Cone support spindle (3 fig.7) cone holder arm spindle centre does not run freely
Clean away yarn or fluff. With the cone (12 fig.15) assembled the spindle should turn
➥
freely.
Overfeeders 1-4 (fig.9) rotate in the opposite direction from that of the yarn because of incor-
rect threading
➥ Follow the threading instructions
The cone is too soft and the yarn guide (1 fig.7) touches the cone
➥ Increase the braking effects and rotate the counterweight (2 fig.7) to a position opposite the
spindle (3 fig.7). Check the position of the yarn guide (see fig.20)
Overfeeders do not work
➥ Check that the feeder belt (1 fig.13) has not come out of the pulley grooves. Clean and reas-
semble correctly.
The yarn guide drops the yarn or snaps it on the cone
➥ Adjust the position of the yarn guide (1 fig.7) so that the taut yarn barely touches the bottom
bushing. The gap between the yarn guide (1 fig.7) and the cone (12 fig.15) at the bottom should
be 4.5 - 5 mm (see fig.20).
Variation in cross-over angle, running speed, braking or threading during cone formation.
➥ Do not perform any parameter adjustments from the time the cone is started until it is com-
pleted.
Fluff under the yarn brake plates
➥ Clean both sides of the plates.
Cones too dense
➥ Counterweight too far back.
➥ Insufficient braking.
➥ Arm too tight.
Cone vibrates
➥ Tube faulty or not suitable for the spindle.
➥ Arm insufficiently tightened; regulate lock-rings.
Turns were too slack at the beginning
➥ The acceleration ramp is not working or is turned off.
➥ The spindle centres are not running freely.
➥ Arm too tight.
➥ Insufficient counterweight on the cone.
➥ Regulate. If this does not solve the problem, when starting briefly rub the yarn between the
fingers, as the yarn is too slippery.
