Abstract

In fase di realizzazione di elementi multistrato con bordo di sovrapposizione, partendo da una lastra costituita da almeno uno strato di copertura (29) rigido e da un anima (28) in materiale espanso, si evita, in occasione del taglio, la formazione di sbavature, in virtù del fatto che il taglio di separazione viene effettuato con una sega a nastro (3), mentre quello di incisione viene effettuato con una sega circolare (25).(Fig. 1)
