Photoelectrically controlled line follower apparatus |
摘要 |
A photoelectric follower for following centers or edges of lines to control associated cutting torches produces a sharply-defined edge-of-line signal by making the 'black' and 'white' level signals of equal amplitude and opposite polarity. The follower has adjustable 'lead' and a kerf width adjustment. Line scanning is effected by a piezoelectric rod.
