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. |
