Rotary Hot Glue Labellers

Premium technology - universal hot glue labelling particularly for PET containers

Gernep Rollina

All-round labelling with hot glue, in particular for PET-bottles – cost-effective and logical.

Labelling machines with unmistakable performance.



This fully automatic labelling machine was specially developed for economical wrap around labelling of glass, plastic and metal containers of various shapes and forms.

Wrap around labelling with pre-cut paper or plastic labels works without the involvement of a gluing drum. The hot melt is applied economically as spots onto the container through high pressure nozzles and the container takes the label directly from the magazine.
The final gluing is by a continuous vertical glueoff strip. Using this economical and clean gluing method means we save not only on change parts and components but also minimise the daily cleaning requirements.

Operation – precise and user friendly: The ROLLINA is very easy to use. The machine works continuously with easy handling and a minimum of operating costs. Changeover to other containers and label formats is quick. The closed hot melt system is absolutely low maintenance. The ROLLINA is complete with transparent, attractively shaped guarding and meets the highest accident prevention standards.

Easy changeover: The ROLLINA provides for exceptionally quick changeover to other bottle sizes. Apart from the guiding parts, there is only a timing belt pulley to change for another container diameter. The initial gluing is adjusted by a simple 2 way setting.

Speed range : 20 to 700 per minute. The labelling machines are customer driven solutions adapted to the speed and size. Hence we produce small and compact machines for lower speeds right up to high performance machines over a whole range of equipment configurations.

• Comprehensive safety systems

Available features

Firmly seated labels with very low glue usage



Hot melt is applied contact-free onto the container in spots with a hot melt unit through nozzles. These glue spots on the container pick off the label from the fixed label magazine. The final gluing is by a vertical gluing strip on the end of the label. Any foreign material ingress is effectively prevented because it is a closed system without glue recycling, thus minimising cleaning.
When there are different label heights, nozzles required for gluing are simply activated or deactivated.



Control of Bottle Plates


The control of the bottle plates varies with machine type.

Mechanically via cam segments.... or
With a timing belt that controls the rotation of the bottle plate.
or utilising Servo motors located at each bottle plate.

The latter allows a recallable program to rotate every container size to suit, ensuring perfect application of the labels for each set up.

Mechanical container aligner


The container aligner has special alignment systems to guarantee an exact alignment of the container.



Flexible and cost-effective


The labelling system can be easily and cost-effectively retrofitted for other bottle designs.
The rotary table is divided into segments so that labour-intensive changeover is no longer required, and often not all the cams need to be changed.
Bottle alignment, hot glue assembly and coders etc can be added at any time.

Label monitoring


Sensor based and/or a camera based system can check the presence and alignment of labels on containers of all types. Bottles where labels are incorrect can be rejected accordingly.
 

 

Precise rolling

The turning of the bottle plate of the ROLLINA is for cylindrical containers via a precision drive belt. The label is pulled taught by the turning action, and then securely attached by way of the final glue strip.

When processing molded containers, the turning of the bottle plate is operated by way of special control pad system that provides a specific turn for the molded container.

Servicing a breeze

The complete electrical system for the drive, servo motors, photoelectric controls and camera system is clean and easy to maintain and is integrated into the machine base. Separate space-consuming control cabinets are not required.

Drive and Control

The drive is a frequency-controlled three phase AC motor.

The integrated PLC not only ensures a reliable mode of operation, but it also opens up the possibility of readily upgrading with various additional attachments.

Multiple Configurations

The modular design of the machine means that the carousel can be of different diameters to suit the speed required.

For lower speeds the carousel can be extremely compact.
