BH range coating heads are used for the application of adhesives where it is necessary the lamination of two or more materials, such as textiles, for the profile wrapping or to produce films.
Their main purpose can be found in the textile, woodworking, automotive, converting and graphic sector.
BH range coating heads are a highly customizable accessory, as their width can be changed according to the manufacturing requirements of the customer.
These applicators differ for their high reliability, as the adhesive coating will always result uniform and constant.
Strengths of our BH range coating heads are the construction material, as it is a particular steel alloy, and the special hardening treatment applied on the lips: as a matter of fact, we have engineered and developed a specific hardening treatment, in order to obtain a long-lasting and performing final product. This special treatment provides to our heads a high quality of the finish compared to standard treatments, for a uniform coating without stripes and a high endurance against abrasion and productive wear, keeping in this way the product like new and preserving its original technical specifications, guaranteeing a hardness up to 70 HRC.

Electropneumatic applicators/jetting heads are used for accurately dispensing the hot melt adhesive already melted and delivered from the heated hose.

They can be manufactured for automatic dispensing, via solenoid valves, or for manual dispensing, via related trigger.

Applicators/jetting heads can be supplied complete with modules, nozzles, solenoid valves etc. and can dispense the hot melt adhesive in beads, dots, lines, spray etc.

BD range drum melting units have been engineered for melting 200 lt or 20 lt barrel adhesives and are the best solution for reactive polyurethane (PUR) adhesives. These kinds of adhesives, in fact, tend to reticulate in contact with oxygen, but thanks to a teflon-coated aluminium plate covering whole drum contents, just the adhesive in contact with the plate will be melted, while the remaining inside the drum will be preserved entirely.
BD range drum melting units can also be used as premelter for the melting of self-adhesives for the following feeding of a tank unit.**
Available on request the tandem working mode for two drum units, in order to avoid the stop of the productive cycle during drum exchange.
All drum melting units are also equipped with remote assistance.

TYPES OF ADHESIVES:
PUR = reactive polyurethane
UV curable
**PSA for the following use in a tank melting system

TYPES OF PLATES:
FLAT
FINNED
HIGH MELT FINNED

• Teflon-coated drip catcher in order to avoid adhesive leaks during drum exchange
• Siemens touch screen operator panel
• MELT ON DEMAND system: the drum unit melts only the adhesive part in contact with the melting plate

BT range tank melting units are used for melting granules or sticks hot melt adhesives.
The structure of the standard melting unit model involves the assembly of a tank plus a grid, guaranteeing a better melting compared to the model assembling just the tank.
Thanks to their structure, BT range tank units result very easy to clean and versatile, due to the different capacities of the adhesive tanks which can be assembled.
BT range tank units are all arranged for installing various communication systems with other machines such as Profinet, Profibus o Modbus.
All tank melting units are also equipped with remote assistance.

TYPES OF ADHESIVES:
UV curable
PSA
EVA
**PUR optional version

TANKS CAPACITIES (lt):
6 – 12 – 25 – 50 - 100 – 160 - 300

• Arrangement for assembling pressure sensors
• Arrangement for assembling loading cells
