Thanks to the partnership with company Buson Srl, KRONN decides to produce internally the sandwich panel line core structure.
This structure is made up of electro-welded beams with reference surfaces processed by CNC machine. This makes our sandwich panel line the strongest one in the world.
The spindle is self-expanding in order to block the coil by means of a hydraulic cylinder activated by a hydraulic box complete with all the valves necessary for its operation.
The same hydraulic box activates the transversal movement of the structure to align it with the rest of the sandwich panel line.
The spindle is rotated through an electrical motor equipped with a sensor which detects the height of the coil loop.
