Auto linear hot glue labeling machine is of the new generation, suitable for handling labels in different materials, as paper laminates, polystyrene-polypropylene-polyethylene compounds, a. o. The labels can be applied onto
the containers using hot-melt glue compatible with the material of the label and of the container.
The machine is equipped with a double roll rest.
The electronic web aligner automatically corrects any vertical web misalignment.
A servomotor interacting with the notch detector controls the web driving system, and adjusts the label
dispensing speed by comparing the real printing speed with the speed stored in the format menu.
The fine adjustment of the knives’ interference provides for a clean and constant cut, and for a long life of the
The transfer roller gets the pre-cut label from the cutting roller. The label is drawn and kept without using
grippers, and without adding special treatments on the roller.
Thanks to a special suction system, the label sticks to the transfer roller, while the glue is distributed on both
label ends prior to its transfer onto the container.
The machine distributes the hot-melt glue on the leading and trailing edges of the label. The system features a
selfcontained glue tank with gear pump with full control of all heated zones. The glue is recirculated through an
enclosed and insulated system.
The design of the glue tank provides for simple cleaning and maintenance because entirely separated from
the glue roller.
The glue roller features a scraping system that does not require adjustments, providing for a constant and very
thin glue layer. Moreover, the glue heating system start-up is timed on weekly.
The mechanical parts of the label cut and application station are lubricated by centralized greasers, for a
simple maintenance and improved reliability.
All systems are designed to perform without any need for operator adjustments or tuning.
