Abstract

Procedimento per la realizzazione di manufatti strutturali (P) in lamiera metallica, in cui un nastro (4) di lamiera viene fatto avanzare lungo un piano (?) e tagliato mediante una testa laser (T) in una pluralità di lastre (L1, _, L4); ciascuna lastra viene fissata su una rispettiva superficie di supporto (16) di un portapezzi (6) rotante e saldata ad una lastra precedentemente tagliata lungo uno spigolo comune da un'altra testa laser (S). Vengono descritte varianti del procedimento e delle relative apparecchiature per la realizzazione di scatolati a sezione quadrata, rettangolare, e di scatolati rastremati.(Fig. 1)
