For the production of roof and walls panels with excellent fire resistance requirements, the line can be equipped with a parallel additional series of machines dedicated for the preparation of insulating material core made of mineral wool.

This line automatically loads the boards of insulation material from stack with an high speed bridge loader to deposit on a series of conveyors that infeed to the cutting machine.
The cut of mineral wool strips is made by circular disks mounted on interchangeable cassettes for a short time thickness change.

The strips proceed through a tilting station to be introduced into main line between the two profiled sheets.
A multicomponent distribution system spreads the glue onto the inner side of the profiled metal facing that join with the insulation material.

For the roof panel production, a dedicated line loads, cut, feeds and inserts the trapezoidal strips into the corrugations of the profiled sheet.
