Abstract
Apparatus for sensing faulty knitting needles includes two needle sensors that are supported in predetermined relation for concurrently sensing different portions of the same needle. An indicator produces an output indicating that a sensed needle is defective in response to a differential change indicative of a faulty needle in the output indications of the two needle sensors.
