Abstract

Per effettuare l'esplorazione dell'articolo (30, 31) in lavorazione su una zona anulare intorno al piedino premistoffa in una macchina per cucire, è provvisto un sistema (25) di lenti di forma anulare, che produce l'immagine di una linea circolare (33) nel piano (A) dell'articolo in lavorazione, circondante concentricamente il piedino premistoffa, sulle estremità di entrata della luce di una pluralità piuttosto grande di fibre fotoconduttrici (26), disposte parimenti in forma anulare. Con associazione individuale, queste fibre fotoconduttrici (26) portano ai singoli elementi di ricezione della luce di una riga di sensore fotoelettrico in una apposita camera, che può essere sottoposta a lettura ciclica.(fig. 2).
