Photoelectric Detector for a Register Control Device Within a Rotary Printing Machine
Реферат: The detector comprises a row of reading devices arranged to face the band to which the printing is to be applied. Each device comprises one or two illuminating optical fibres (30) each associated with a single reading optical fibre (40). The reading fibre conveys light reflected by the band to one of a row of photodiodes situated behind the machine. The extremity of each reading optical fibre (40) is rigidly held in position with a spherical of hemi-spherical lens by means of an optical quality glue. The refractive index of the optical glue used is ideally equal to that of the lens used to focus the image of the band within the optical fibre.
