Abstract

Procedimento per rilevare le fibre sintetiche nella lavorazione del cascame di seta, in cui una zona sostanzialmente definita di un velo dì fibre di seta (20) sostanzialmente parallelizzate viene illuminata per trasparenza con luce bianca (23), detta zona venendo ripresa da una telecamera (24) associata ad un sistema di elaborazione, detta zona venendo altresì illuminata per trasparenza con luce polarizzata (25) e contemporaneamente ripresa da una telecamera (26) anch'essa associata al detto sistema di elaborazione, le immagini (14, 15) riprese da dette telecamere (24-26) venendo elaborate e confrontate per definire posizione e lunghezza delle dette fibre sintetiche.Apparecchiatura per rilevare le fibre sintetiche nella lavorazione del cascame di seta in fibre presentante un piano trasparente (36) su cui è deposto un velo di fibre di seta (20) sostanzialmente parallelizzate al di sotto del quale sono presenti una prima ed una seconda sorgente di luce, essendo una a luce bianca (23) ed una a luce polarizzata (25), cooperarti con almeno una telecamera (24,26) associata ad una unità dì elaborazione (27).
