Hole Detection
An incandescent photoelectric control and sensor array can detect a
hole as small as 1/6'' in diameter moving as fast as 600 FPM.
The array contains a line of closely-spaced high-speed light
sensors mounted behind a cylindrical lens. Flood lights are mounted
above them, and the web passes between the lights and sensors. When a
hole flaw passes over the sensor, light momentarily falls onto one or
more of the sensors, causing the control relay to actuate.
The control has a time delay feature to ''stretch'' the brief
light signal to a length adequate for a positive relay contact
reversal. With the short delay range in the control, and effect
similar to an on/off function can be achieved.
