Abstract (en)
[origin: EP0990473A2] The device has an assembly station with a folding device by means of which the two pairs of opposite edges of each plate can be folded respectively with the edges of the plates above and below it. The prefabricated plates are conveyed to the assembly station from the pick-up stations where they are stacked, the plates in each stack being oriented at 90 degrees to one another ready for assembly.
