Other Specifications:

The machine includes a primary unwinder, a secondary unwinder, an applicator body for solventless adhesives, a bridge with bearings for the passage of the material, a laminator body, a winder & a chiller

Compared to a standard machine, the machine has :
Extra secondary unwinder with a reel diameter of 1.5 m
Extra rewinder, roll diameter 1,5 m
Higher web tension for paper up to 280 gr/m2
Dosing system for solvent-free single component glue (monodispenser)
Additional web guide
Please note that the extra costs for the unwinder and rewinder also include the modification of the electrical installation, adaptation of the bridge, carbon fiber reel shafts to reduce the weight of the shaft, etc.

Two dispensers are included: single component and two component:
The single component is VEA model Monodispenser. It is used for paper laminates only
Two-component dispenser/mixer designed by Comexi, with very precise gear pumps and alarm system if the proportion changes. Mainly used to laminate two films.
There are also heating belts for 200kg drums.
