Abstract

Il dispositivo comprende almeno due radiatori di luce (41, 42) disposti su due lati della cimossa (2) al di sopra della pezza (1), dei quali ciascuno emette un fascio di raggi luminosi (7) che colpisce la pezza (1) nella zona della cimossa e presenta una sezione trasversale sovrastante la cimossa (2) trasversalmente alla direzione di movimento della pezza (1) orientata verticalmente al piano di disegno. Visti nella proiezione parallela alla direzione di movimento della pezza (1) i due fasci di raggi luminosi (7) sono inclinati contrariamente tra di loro con un angolo (6) uguale rispetto al piano della pezza. Una videocamera (8) fornisce riprese solo nella luce di uno o dell'altro dei due radiatori di luce (41, 42). I videosegnali ottenuti con l'una e con l'altra ripresa si memorizzano e si sottraggono tra di loro. Dall'analisi dell'andamento di questa differenza di segnali, risultante nella zona della cimossa, si determina la posizione della cimossa.Fig. 1
