Abstract:

A rundown detector system for controlling operation of the cylinder of a circular knitting machine includes a photoelectric circuit, including fiber optic means and a sensor for sensing predetermined extended periods of low reflected light level and emitting signals to a logic circuit. The logic circuit includes a timer and counting mechanism for stopping rotation of the machine cylinder if a predetermined number of signals are emitted to the logic circuit within a predetermined time period. The timer mechanism also prevents stopping of the machine cylinder, upon start-up of the machine, until a predetermined amount of knit fabric absent of defects has moved past the sensor.
