Abstract

L'invenzione riguarda un metodo e la relativa apparecchiatura per il rilevamento, a mezzo di scansione con teste di lettura indipendenti, dello spessore di un film mentre questo avanza.La scansione avviene contemporaneamente secondo una direzione parallela alla direzione di avanzamento del film e secondo una direzione trasversale e le misure rilevate vengono visualizzate contemporaneamente su un monitor mediante la rappresentazione contemporanea di due profili, anche sovrapposti, di colore differente.
