|
(6) Symptom: | Large variations in the sheet overlap |
Possible causes: | – The sheets may slip under the rolls during feeding of heavy paper without weights |
| in the gravity rollers. Add weights to the gravity rollers. |
| – The sheets are pressed excessively against the gates during feeding of very light |
| paper if the weights in the gravity rollers are to large. Remove the weights. |
(7) Symptom: | The upper snapping roller was turning and stopped suddenly while |
| the machine was running |
Possible cause: | – The reasons may be too small of a gap between the upper snapping roller |
| – Because of the roller friction against paper, the motor overheated and the fuse |
| tripped. Reset the fuse in the distributor. ( Service technician repair only) |
(8) Symptom: | The feeding table does not rise automatically. |
Possible causes: | – The reason may be, while the paper pile was moved into its working position, the |
| table rise wasn't switched off by the sensor, which is located on the roll bar in the |
| center of the machine. |
| – The sensor in the feeding head didn’t switch on due to the adjustment knob on the |
| feeding head was turned completely to the right. |
(9) Symptom: | The snapping assembly operates correctly at low speeds but loses |
| its efficiency at higher speeds |
Possible causes: | – Low air pressure and flow in the pneumatic circuit of the laminator. Ensure the air |
| pressure source is adequate. |
| – Increase the air hose diameter from the air source. |
