B & H Labeling Systems introduces the new B & H Glue Extrusion System (GES), a patent-pending extrusion glue system that is fully automatic, recipe-driven hot melt applicator for roll-fed labeling.
Compared to traditional glue wheel systems and spray glue systems, the GES improves the accuracy of glue application and produces void-free glue patterns while eliminating vacuum drum re-padding.
The system minimizes downtime, reduces glue waste, improves the quality of labeled containers and requires no operator adjustments during production.
The automatic PLC-driven GES applies a precisely extruded film of hot melt adhesive to preprogrammed locations on a label through a vertical pattern nozzle.
Using proprietary algorithms developed for each adhesive, the system uses a controlled combination of pressure and temperature to accurately and consistently extrude and apply hot melt adhesive to labels regardless of fluctuations in production speed.
The B & H GES is comprised of four key components: extrusion tower assembly, dedicated PLC / HMI, all-metal GES vacuum drum, and melt-on-demand glue tank.
It is available as an option on new Marathon and BH8000 Series labelers, and is offered as an aftermarket upgrade for installed Marathon, BH8000S and BH8000U labelers.
The GES can run at speeds up to 600 cpm.
The GES eliminates glue slinging, angel hair and glue build-up on the vacuum drum and glue wires, which maximize uptime by requiring fewer operator adjustments and labeler stoppages.
Its closed system reduces glue recirculation by more than 90%, which eliminates overcooking the glue and damaging its bonding properties.
The system reduces glue waste as there is no glue pan overflow, draining of glue tanks full of overcooked or contaminated adhesive and glue slinging.
GES vacuum drums are high-precision, all-metal drums that eliminate the need for vacuum drum re-padding.
The vacuum drum and extrusion tower assembly have a no-impact interface – the vacuum drum does not come into contact with the pattern nozzle as it deposits glue on labels.
This no-impact interface means the GES vacuum drums do not experience wear like conventional vacuum drums.
A PLC and HMI controls the glue application process.
Recipes for every adhesive/container/label combination are entered and stored in the PLC where they are accessed via the HMI.
The system’s recipe-driven repeatability minimizes operator intervention while maximizing system performance and the quality of labeled containers.
