Integrated automatic dispensing system for the automatic regulation of the application primer.
The system dispenses the quantity in gr/m2. The calculation is done in gr/m2 following the working speed by the computation of the requested quantity a m2 with the width of the substrate that you want to apply with primer.

Hot melt PUR applicators for reactive thermo melting adhesives (HOT MELT PUR) complete with CPU for the centralized supervision of the machine functions, of the processing data and times setting functions, of alarms and safety functions. Automatic dosage of glue disbursement

Model “LUNA” for the wrapping of extruded PVC profiles and aluminum profiles with foil on a coil. Bonding by Reactive Polyurethane Hot Melt (HMPUR).

INITIAL SET-UP
The first set-up is done by the operator with the help of a multifunctional joystick. All the production parameters are memorized in apposite recipes during the initial set-up.

PRESSING ROLLS AND AUTOMATIC POSITIONING
The machine offers the “traditional” way of positioning the pressing rolls. The automatic pressing control compensates possible variations on the profile dimensions.

QUICK CHANGE OF THE PRESSING ROLLS
Quick change system for pressing rolls. The type and the position of each roll is managed by the control software.

Machine type “NWA” for the wrapping of panels in metal, extruded PVC, ABS, PS etc. with coiled foil in flex paper, PVC or CPL laminate. The supporting material can have a width between 500 and 1350mm. Bonding by use of Reactive Polyurethane Hot Melt (HMPUR).

Machine type “NWA” for the wrapping of profiles and panels in metal, extruded PVC, ABS, PS etc. with coiled foil in flex paper, PVC or CPL laminate. The supporting material can have a width between 10 and 1350mm. Bonding by use of Reactive Polyurethane Hot Melt (HMPUR).

Thanks to their innovative design, the Hot Melt and Hot Melt PUR slot nozzles are compact and simple to use and maintain. They perform a homogeneous distribution of the glue in all conditions, spreading it precisely along the whole length. Also on PVC, they also provide high quality distribution on special foils.
