| PROBLEM |
CAUSE |
SOLUTION |
| Formation of tangles around the
pressure roller |
Bad rollers, with corrugation
and furrows, cut. |
To change rollers |
| |
Too high enlargement for the
respective zone of breakage |
To lower the enlargement |
| Audible blows in the main zones
of breakage |
Too low pressure of the
Polyurethane rollers |
To increase pressure of the
cylinders (to fit wings indications of the machinery manufacturers) |
| |
Too much amount of material in
the main zones of breakage |
To choose the greater
pretension. ATTENTION: The enlargement between plates heating engineers and the
speed of entrance must be constant, if they cannot occur diferences in the
shrinking, can be found . Corrections can be made by changing the plates
temperature. |
| |
Covering of the rollers is
hollow due to the wearing down |
To change rollers |
| Long breakage in groups or
breakage |
Too low pressure of the Rubber
rollers, jebe (Polyurethane) |
To increase the cylinders
pressure ( fit to the indications of the machinery manufacturers) |
| |
Covering of the rollers worn
away, too thin or hollow |
To change rollers |
| |
Smooth inferior cylinder, layer
of worn away ceramics |
To change rollers |
| Insufficient shrinking |
Mistaken temperature of plates |
To change temperature of plates |
| |
Mistaken enlargement between
plates |
To change the enlargement
between plates |
| |
Defect in the indication of the
temperature or the heater. Indication does not correspond to the effective
temperature |
To repair defect |
| |
Defective Cooling Device |
Repair and clean if it were
necessary |
| |
Heating Plates do not close correctly |
To review the closing of plates |
| Shrinking too much hard |
Mistaken temperature of heating
Plates |
To change temperature of plates |
| |
Estiraje mistaken between
heating Plates |
To change the estiraje between
plate |
| |
Defect in the indication of
temperature of heating Plates or in the heater |
To repair the defect |
| Impossible to control the
shrinking |
heater do not close correctly |
To review the closing of plates |
| Too much volatile fiber |
Feeding of the tape is rough,
for that reason there are damages in filaments |
To repair the defect |
| |
Too high pressure of the rollers |
To lower the pressure of the
cylinder |
| |
Covering of the rollers too
thin, worn away or hollow |
To change the pressure rollers |
| |
Too smooth inferior cylinder,
layer of worn away ceramics |
To change cylinders |
