    In this particular moment, being it not possible to take part at exhibitions, Uteco has organized the first of a series of Webinars which will focus on the presentation of the latest developments in various fields. The first Webinar will be held on December 2nd on the new coater/laminator Dualam. The Webinar will take place at the Uteco technological center ConverDrome, located at Uteco headquarters, and will be broadcasted through Youtube in two different sessions, the first one at 9.00 a.m., and the second one at 5.00 p.m. The participation will be confirmed after signing up at the following link: REGISTRATION

    Dualam system is an innovative, eco-friendly laminating solution that performs as well as solvent-based adhesive technology, while being voc free. The system includes a laminating machine of the same name, developed by a special Team coordinated by Luigi Bertagna” historical” founder Member of Uteco and Chief of the Special Machines Division. The machine is composed of two coating groups, one is a solventless unit for NC0 component, the second group is the semi-flexo unit with a closed chamber doctor blade for OH component, then one laminating unit.
    The solventless unit is also equipped with an automatic washing system for cleaning all the rollers, using special spray nozzles integrated into the machine. This washing system uses a total green, non-flammable and non-toxic detergent, able to remove any trace of adhesive after the lamination process. The quantity of detergent is about 3 liters. This operation requires about 3 minutes and guarantee the rollers’ cleaning. The unit is completed by a fume suction box positioned above coating cylinders for elimination of the harmful emission, it is connected by an efficient suction fan.

    The semi-flexo unit with a closed chamber doctor blade consists of three cylinders:

    – a motorized adhesive coating gravure roller with Uteco patented system “Thermilox” sleeve, which has the advantage of keeping at the pre-set temperature, the coating adhesive constant during the entire production process, the temperature is controlled by a independent thermoregulation;
    – a motorized pressure rubber sleeve roller with independent pneumatic pressure system;
    – a steel counterpressure cylinder which has the function of keeping the tension of the film controlled and constant.

    Then there is a special heated closed chamber doctor blade with independent thermoregulation and aa heated tank, with an independent thermoregulation unit, complete with gear pump controlled by inverter motor.
    The new coating technology developed with the semi-flexo unit enables the homogeneous application of minimal amounts of adhesive over the whole material surface.

    “Sustainability has always been a key emphasis for our company, as demonstrated by our significant reuse of energy as well as our ongoing efforts to improve plant efficiency, which includes the adoption of the Industrial Internet of Things system. Thanks to this consolidated technological partnership, the DUALAM machine meets emerging market needs for production efficiency, cost reduction, and, of course, sustainability”, commented Aldo Peretti, Group President and CEO Shareholder, Converting.

    The DUALAM system will be available across Europe, Latin America and the North America Region through the sales networks of Uteco, Sun Chemical and Synaptik from Q1 2021.
