Abstract
Apparatus for the detection of defects in a moving band, characterised in that it comprises optical means (25, 27) for inspection of the lower face and optical means (29, 31) for inspection of the upper face of the band, separate optical means (33, 34) for detection of the edges of the band, electronic means (35, 36) for indication of defects associated respectively with the optical means (25, 27, 29, 31) for inspection of the lower and upper faces of the band, electronic means (37) for indication of the presence of holes in the band, associated with the optical means for detection of the edges of the band and means (38) for processing the information delivered by the electronic indication means (35, 37, 38) and means (42) for displaying faults in the upper and lower faces of the band and holes in the latter, the display means being connected to the information processing means (38). <IMAGE>
