| POSSIBLE REASONS | METHODS FOR SOLVING PROBLEMS |
|---|
| The label peels off |
| Too little glue was applied. Increase the amount of glue applied. | Check the glue supply with a pump, if necessary, increase the number of cycles per minute. |
| Adhesive is not in contact with the surface of the paper. A dry glue film is on the back of the label. | The surface of the bottle is not cleaned sufficiently. Adhesive is contaminated with a foreign substance. |
| A large output on an adhesive pallet. | Replace worn parts or repair. |
| The pressing mechanism is not properly adjusted. | Adjust the necessary settings. |
| The label/coquette edges peel off |
| The edges of the labels are not lubricated with glue. | Check whether the labels are completely covered with a uniform layer of glue. Configure the labeling machine. |
| Incorrect label position. | Adjust the necessary settings. |
| The clamping mechanisms are not adjusted. | Adjust the necessary settings. Ensure that the water supply to the pressing mechanisms is properly adjusted. |
| The area of the glue pallet is less than the area of the label. | Check the shape of the adhesive layer on the back of the label. Select the adhesive pallet of the required size. |
| The glue pallet is not completely covered with adhesive. | Check the adhesive supply from the glue shaft to the pallet. Adjust or replace the glue pallet if necessary. |
| Ready labels have the wrong fibre direction. | Contact the label manufacturer. |
| Output on the glue shaft. | Replace worn parts or repair. |
| The surface of the neck of the bottle does not match the shape of the coquette. | Carefully check the shape of the coquette with the neck of the bottle. |
| Adhesive pumps poorly |
| Adhesive is cold. | Preheat adhesive to the operating temperature in accordance with the technical specifications. |
| Adhesive is mixed with a different trademark of glue. | Rinse the equipment thoroughly. Replace the container with the proper adhesive. |
| Low glue viscosity. | Apply adhesive with a higher viscosity. |
| Adhesive splits and forms threads |
| Too much adhesive is applied. | Reduce consumption. |
| The glue shaft and glue pallets are damaged. | Replace or repair the shaft and glue pallets. |
| Traces of adhesive on the bottle. Bottles / labels are glued together after labelling |
| The glue was washed off with condensate. | Reduce the thickness of the adhesive layer. Add air to the labelling machine. |
| Incorrectly configured labelling machine. | Adjust the necessary settings. |
| “Floating labels” |
| Too much adhesive. | Reduce the adhesive layer thickness. |
| High bottle humidity. | Increase airflow around the labelling machine. |
| Weak strength of wet labels |
| Adhesive with excessive adhesion. | Contact the glue supplier. |
| Weak strength of wet labels. | Use labels made from stronger paper. |
| Incorrect clamp position. | Adjust the necessary settings. |
| More than one label is removed from the cassette |
| The labels stick together due to insufficient print drying time. | Soak a stack of labels to separate them from each other before loading into the cassette. |
| Glue spray occurs. | Check to see if the glue supply can be reduced. |
| The cassette stops are not adjusted. | Adjust the grip and pressure in the cassette. |
| The labels are not removed from the cassette |
| Adhesive with insufficient adhesion. | Contact the glue supplier. |
| The stops on the cassettes are not adjusted. | Adjust the grip and pressure in the cassette. |
