Abstract

L'invenzione riguarda uno sbozzato in forma di lastra di materiale plastico sostanzialmente rettangolare, trasformabile per fresatura, in modo noto, in un frontale di montatura di occhiali. Tale lastra presenta zone cave, prive di materiale, almeno all'interno dei cerchi ed al disotto del nasetto del frontale come pure, eventualmente, una parte principale a spessore assottigliato e zone a spessore pieno almeno in corrispondenza del nasetto e degli attacchi delle cerniere. Lo stampo di fabbricazione di un tale sbozzato è realizzato essenzialmente in forma di una camera piatta, rettangolare - in cui una miscela di materiale plastico in scaglie, grani e/o pezzi viene introdotta e passata a cado - degli inserti di occlusione delimitando nelle camere delle zone cave, prive di materiale. Tali inserti possono inoltre essere realizzati in materiale cedevole, che. viene pressato allo stesso momento del materiale in scaglie.
