Abstract
A feeder for feeding material along a feed path. The feeder includes a conveyer, a sensor and a control system. The conveyer operates at a normal cyclical rate to transfer the material along the feed path. The sensor mounts on the feeder and detects the material being fed. The sensor detects and signals fault when the material is fed in an undesirable manner. The control system couples with the conveyer and with the sensor and responds to the sensor to slow the conveyer to a reduced cyclical rate when the sensor signals fault. The reduced cyclical rate is less than the normal cyclical rate to enable the feeder to self-correct and thereby eliminate the fault. When the conveyer operates at the reduced cyclical rate and the feeder has self-corrected, the sensor ceases to detect fault and the control system speeds the conveyer back to the normal cyclical rate.
