Easy UBM Series applicators for Polyurethane Reactive (PUR) adhesives in cartridges are ideal solution for melting and applying small quantities of PUR adhesive in a variety of sectors such as paper-transformation, bookbinding, textiles, and assembly.
Once the PUR cartridge is inserted and hooked into the melting plate, the lower piston (the only component in movement of the whole system), pushes the cartridge from the bottom guiding it and melting only the required amount of adhesive. With the emissions of radiation upwards, it will be heated only the required amount of adhesive necessary for the supply, avoiding to melt the entire cartridge as happens in all the other equivalent systems. The lower part of the cartridge will always be ambient-temperature until it will be in very close contact with the melting plate, assuring a perfect PUR preservation that won’t undergo deteriorations or reticulations.
Another advantage of the Easy UBM Series applicator is the total absence of glue residuals in the system, that could involve the channels’ clogging and consequently a continuous maintenance of the machine (almost once a week); in addition, thanks to the system technology, is not necessary the use of dry air for prevent the product oxidation and its reticulation in contact with the air humidity.

LCD DISPLAY AND INNOVATIVE PROGRAMMING
This feature provides images of all sections of the machine (tank, pipes, and guns) and the relevant parameters, making it extremely simple to programme the system even for non-specialist personnel. There are no problems involving codes or foreign languages to interpret. A notification area constantly and dynamically monitors the machine's status. Specific messages are displayed for alarms, errors and malfunctions. A rotary switch is used to set all system parameters very easily.

PUR CARTRIDGES
The system uses mono-component PUR adhesive cartridges with a diameter of 125-150 mm and maximum height 200 mm. The cartridge fits directly into the tank with its aluminium inliner and there is no need to add inert gas or dried air. This procedure prevents harmful vapours from being released during the cartridge change phase – a simple, quick and completely safe procedure, thanks to a special system.

EASY MAINTENANCE
All parts of the applicator can be inspected easily because of a practical body design system that opens quickly to facilitate cleaning, especially around the pressure plate area. Thanks to this innovative construction method the entire plant requires almost no maintenance, with clear savings in terms of time and money.

GEAR MOTOR
The applicators are fitted with variable speed AC motors run by horizontally positioned inverters. This arrangement minimises overall dimensions and provides easy access both for inspection and maintenance, through a quick connector and an easy-to-open body system.

HIGH PRECISION GEAR PUMP
The system is fitted with very precise and reliable gear pumps made of fully tempered high speed steel (HSS) with different flow rates. Like the other internal parts of the applicator, the pump is easy to remove in case of maintenance or replacement.

BY-PASS VALVE FOR PRESSURE REGULATION AND RELEASE
This valve maintains the pressure constant with machine settings and ensures the utmost safety during system operation by releasing the pressure of the adhesive inside the plant automatically and safely, even in the event of an emergency.

PRESSURE CONTROL GAUGE
The applicator display shows the output pressure of adhesive at the manifold, monitored by a sophisticated control system. The display can be read like a traditional digital pressure gauge, indicating the pressure of the adhesive in bars.

"MELT ON DEMAND" TECHNOLOGY
The melt on demand melting system only heats the quantity of adhesive required. A piston is activated that presses the cartridge onto the melting plate to feed the manifold. This system makes it possible to reduce thermal stress to a minimum, protecting the remaining adhesive that is perfectly preserved in its original packaging.

In the new U Easy Series applicators for polyamides and reactive polyurethane (PUR) melt hot-melt adhesives the new microprocessor controls all those operations necessary to the system proper running: thermo-regulation in all different system areas, programming control of 8 glue tracks for each of the 4 independent channels. Additional features are: Economy Function, Clock, Weekly Program, Max. temperature alarm, Sequential Heating of all channels and delay Temperature Set Point lock.

HERMETIC MELTING TANK AND SAFETY LID
A large cylindrical, hermetically sealed loading inlet facilitates tank filling. The tank has a capacity of 5 and 8 kg. The tank lid is then blocked by a safety system that prevents it from opening involuntarily or accidentally, and also prevents material from spilling.

LCD DISPLAY
A new LCD display (specifically designed) graphically shows all the machine sections (tank, manifold, hoses and guns with respective parameters), allowing an immediate and extremely easy system programming also by unskilled operators, eliminating problems generated by codes and foreign languages to understand and meaning that the displays are all the same, independently of the country of use. A specific notification area controls the system status constantly and dynamically in all its operation phases. In case of eventual alarms or faults error messages are displayed.

INNOVATIVE PROGRAMMING
Another innovative feature of the new Easy Series is the "Rotary Switch": the selector through which it is possible, with extreme easiness, to program, modify and set section by section all those parameters intended for the system running.

GEAR MOTOR
The applicators are fitted with variable speed AC motors controlled by inverter positioned horizontally so as to have reduced overall dimensions and ease to access both for inspection and maintenance, thanks to a quick connector and to an easy to open body system.

GLUE FILTER
Easy to access and replace, it ensures a better distribution of the adhesive preventing the nozzle clogging due to the presence of impurities in the adhesive.

AIR DRYING SYSTEM
An innovative automatic air drying system (provided as standard and connected to the applicator with a quick coupling connector) removes the air from the tank and replaces it with inert gas or dehumidified dry air to prevent oxidation and thus prevent that the product react irreversibly, in a very brief time, upon contact with humidity in the air.

PRESSURE CONTROL DEVICE
A sophisticated control system shows on the applicator display the adhesive output pressure in the manifold. This visualisation is comparable to a traditional digital pressure gauge indicating the adhesive pressure in bar.

HIGH PRECISION GEAR PUMP
With the same dimensions it is possible to choose between gear pumps of different capacity. Absolute precision and reliability, they are made of super-quick steel and are fully hardened. Like all the inside parts of the applicator, also the pump is easy to remove in case of maintenance or replacement.

QUICK PRESSURE RELEASE AND REGULATION VALVE
It keeps the pressure set constant and ensures the utmost safety during the system use by and releasing the adhesive pressure into the system in an automatic and safe manner, even in the event of an emergency.

The new EASY TOUCH Series applicators for hot-melt adhesives with gear pump are significantly innovative in terms of simplicity of use, productive flexibility, maintenance operations and costs, speed of installation, easy programming, high safety standards, exceptional reliability and total integration with any existing assembly line. They represent a quality solution for application of thermoplastic hot-melt adhesives in several sectors.

The EASY TOUCH systems are equipped with a new microprocessor with 7" LCD Touch Screen colour display, through which, with a single graphic interface showing all sections of the system (tank, manifold, hoses and guns).

NEW MICROPROCESSOR WITH 7" TOUCH SCREEN DISPLAY
The following are some of the main functions of the new user interface: sequential channel heating, machine ready and pump start signals, absolute maximum temperature protection system, Economy Dual Mode, Weekly Program with Daily ECO function, colour status button with real time diagnostics and Screen Saver function, machine parameters and Firmware updates uploaded and downloaded through a USB port, and many more...

NEW MELTING TANK
The new tank was entirely redesigned to ensure perfect efficiency in terms of melting evenness and capacity. The large loading inlet open on 3 sides makes filling easier, optimizing cleaning and maintenance operations. The heaters are positioned on the bottom of the tank and across the melting fins, and are specifically designed to create a special grid to improve the melting of the glue more efficiently, so it can slide directly towards the pump drawing spot. This heating system allows a homogeneous and uniform distribution of the heat improving the thermal efficiency of the whole system with a consequent energy saving.

HIGH PRECISION GEAR PUMP
Gear pumps of different capacities (0,8 - 3,0 - 7,0 - 10 and 20 cc/rev) are available with the same dimensions. These pumps are absolute precise and reliable, made of fully hardened super-quick steel. Like all internal parts of the applicator, the pump is also easy to remove in case of maintenance or replacement.
The pump is propelled by an inverter-controlled variable speed AC motor.

GLUE FILTER
Easy to access and replace, it guarantees excellent quality of application, preventing impurities in the adhesive from clogging the nozzles. There is a wide range of available models (with single or multi-layer filtering micro-mesh, and different pitches starting from 200 micron) depending on the type of adhesive used.

AUTOMATIC PRESSURE RELIEF VALVE
A standard part, it guarantees maximum safety during operation by automatically discharging residual pressure in case of emergency or system shut-down.
